Navigating large college campuses presents significant challenges for new students and visitors, especially with inadequate facilities to identify key landmarks such as administrative buildings, departments, libraries, and cafeterias. This paper proposes the development of a static location-based application for Android smartphones, featuring interactive markers and navigation functionalities to streamline campus navigation. The application allows users to locate desired destinations and receive step-by-step directions from their current location. Additionally, the inclusion of voice assistant-based search enhances user experience by enabling users to vocalize their destination, making navigation more intuitive and accessible. This solution aims to improve overall campus accessibility and convenience for students, faculty, and staff, thereby enhancing the campus experience.

A meta-comparison of link analyses was performed using two eye scanning studies. One study was an analysis of the Etak navigator performed by Antin, Dingus, Hulse and Wierwille, (1990). Antin and his associates compared the Etak system to a paper map control condition and a memorized route baseline condition. The second study was an evaluation of the TravTek system performed by Dingus, McGehee, Hulse, Jahns, Natarajan, Mollenhauer and Fleischman (1995). The TravTek Camera Car Evaluation tested six different navigation conditions (a TravTek visual display of a full, heading-up route map with voice guidance, the same TravTek route map without voice guidance, a TravTek visual display showing a graphic representation of static turn-by-turn information, the same turn-by-turn screens without voice guidance, a textual paper direction list with large legible font, and a conventional paper map). The eye glance data shown in the comparison of these two studies revealed several interesting findings. In all conditions, scanning of instruments, mirrors and signs/ landmarks was a low frequency occurrence and largely constant. Increases in visual attention by a navigation condition draws attention from forward, left and right roadway scanning resources. Thus, navigating draws upon potentially valuable accident avoidance resources in some circumstances. The eye scanning results also shared the relative benefits of the addition of a highlighted route to a moving map display, the simplification of a visual display from a full map to a turn-by-turn graphic, and the addition of a voice supplement to a navigation aid.

A navigation system using a binaural bone-conducted sound is proposed. This system has three features to accurately navigate the user to the destination point. First, the selection of the bone-conduction device and the optimal contact conditions between the device and the human head are discussed. Second, the basic performance of sound localization reproduced by the selected bone-conduction device with binaural sounds is confirmed considering the head-related transfer functions (HRTFs) obtained in the air-borne sound field. Here, a panned sound technique that may emphasize the localization of the sound is also validated. Third, to ensure the safety of the navigating person, which is the most important factor in the navigation of a visually impaired person by voice guidance, an appropriate warning sound reproduced by the bone-conduction device is investigated. Finally, based on the abovementioned conditions, we conduct an auditory navigation experiment using bone-conducted guide announcement. The time required to reach the destination of the navigation route is shorter in the case with voice information including the binaural sound reproduction, as compared to the case with only voice information. Therefore, a navigation system using binaural bone-conducted sound is confirmed to be effective.

This paper describes the driver performance and behavioral interaction results of a comparison between visitors to a major city (Orlando) and local drivers while using differing navigation configurations of an Advanced Traveler Information System (ATIS). The system utilized for the study was TravTek, a device which provided in-vehicle information via color touch screen CRT, steering wheel buttons, and synthesized voice. The TravTek driver interface was developed with the intent of providing navigation, service and attractions, and roadway incident and traffic information to the driver. Both visitors and local users tested six different navigation-aid configurations. The six navigation-aids included: static turn-by-turn graphics and a moving map both with and without voice, a paper map and a textual direction list. The research showed that visitors drove more cautiously, but they made more glances to the navigation-aids when compared to local users. In addition, visitors went off-route and got lost less frequently than local users. Visitors apparently were more careful in driving and navigating to their destinations.

As GPS navigation systems become more powerful, they offer the convenience of more efficient travel, and the use of such navigational aids while driving is now prevalent. Numerous issues still exist during actual use, however, such as incomprehensibility and inaccuracy of voice navigation prompts. The majority of studies have focused on humanized design and the influence on driving behavior of GPS navigation systems, while the psychological factors underlying drivers’ decisions to use them have received little attention. This study employs the extended theory of planned behavior (TPB) to investigate the psychological factors that influence drivers’ use of GPS navigation systems, including the additional variables of navigation involvement, navigation information quality, and distraction perception. Independent t-tests revealed that female, non-professional, novice, and highly educated drivers were more likely to use navigation systems. Factors analysis proved the extended TPB questionnaire to be valid and reliable. Structural equation modeling showed that attitude (0.19), subjective norms (0.14), perceived behavioral control (0.29), navigation involvement (0.36), and information quality (0.16) significantly influenced drivers’ intentions on the use of navigation. However, distraction perception (–0.05) had no significant influence. These findings demonstrate the need for navigation systems which serve drivers better. For navigation system manufacturers, the humanized design should be strengthened. For highway transportation agencies, more consistent designs for road signs are needed to improve the cooperativity between navigation and traffic signs.

A real-vehicle experiment was carried out to study the effects of in-vehicle information on driver workload, during which data of the driver blink duration and frequency were collected to check for discrepancies among drivers with and without vehicle navigation usage. In the meanwhile, the blink characteristics of drivers with vehicle navigation device mounted at three different positions were explored through image prompt or image & sound multi-channel simultaneous prompt. Experimental results showed that when the data of blink with a duration of 0-200ms was distributed at a 10ms interval, the driver blink count distribution curve shows obvious bimodal characteristics. The peak of blink with 50-60ms duration was lower than that with 10-20ms duration when vehicle navigation was not used, and higher when vehicle navigation was used. The difference between medium and long blinks was not significant when the navigation device was mounted at different positions, yet the short blinks showed a significant difference. The peaks of blink count without voice navigation were all greater than those with voice navigation. In particular, without voice navigation, the short blinks increased obviously, and the medium blinks increased relatively, but the long blinks remained almost unchanged. The above results indicate that the driver workload was greater when using vehicle navigation. When the navigation device is installed in position B, the driver workload reaches the minimum. Using voice navigation could reduce driver workload.

In recent years, mobile phone navigation software has been widely used, but the voice broadcast information of many navigation software is not clear, which is easy to cause confused driving. Urban expressway is an important artery of the city. The road and traffic conditions of urban expressways are extremely complicated, and there are many types of exits, which can easily cause confused driving. Therefore, optimization of navigation modes under the condition of multi-exit urban expressways is particularly important. Based on the experimental data of simulated driving, this paper focuses on the influence of voice navigation broadcast timing on driving under urban expressway, founding driver’s behavior is significantly different under diverse navigation modes. This paper uses the principal component analysis method to comprehensively evaluate the navigation broadcast timing, and gives the optimal navigation broadcast timings for various multi-exit urban expressways. In most cases, the first broadcast time should be 1500m from the exit. This paper clarifies the impact of navigation broadcast timing on driving, and optimizes the navigation mode of multi-exit urban expressways, which is of great significance for reducing yaw under navigation and improving navigation services.

In this article, I consider how the redesign of vehicle dashboards has restructured car-related data processes. I do so by charting the emergence of two such processes enabled by the redesign of vehicle dashboards: firstly, the transformation of ‘geodata’ into ‘navigational data’ with the integration of voice-activated navigation systems into vehicle dashboards, and secondly, the transformation of ‘vehicle data’ into ‘driving data’ in the convergence, and customization, of dashboard features and functionality. Both transformations are enabled through strategic design decisions, persuading drivers to participate in novel practices they might otherwise not. Firstly, in that voice-activation is depicted as a seamless, unmediated interface between the normal, natural speech of a driver, and the vehicle itself. Secondly, through the strategy of control, the driver is persuaded to believe they have full(er) customizable power within, and of, the vehicle. The systems discussed here – a voice-activated navigation system built on the What3words platform, and a ‘widescreen’ dashboard in a range of Mercedes-Benz vehicles – are representative of broader efforts within the automotive industry to cultivate a newly ‘datafied’ driving experience.

The interest for indoor navigational systems is expanding daily with concerns among visually impaired people who cannot navigate safely indoors. The main goal of such systems is the localization and direction of the individual who has a wearable device that provides voice commands to navigate indoor buildings. This paper aims to present the design and the implementation of the GuideMe project. The GuideMe project's goal is the design, implementation, and evaluation of a navigation system focused on people who face troubles in indoor moving utilizing a wearable device. Specifically, the focus group is people suffering from visual impairment. The person carrying the wearable device takes guidelines about the location from indoor ultrawide band (UWB) anchors. The commands provided are about indoor direction through voice commands, assisting him to avoid obstacles in his route. The authors present the architecture and the details of the various modules, which consist of the proposed indoor navigation system, and some initial evaluations of the proposed system yielding promising results.

The difficulty associated with spatial navigation is one of the main obstacles to independent living for visually impaired people. With a lack of visual feedback, visually impaired people must identify information from the external environment through other sense organs. This study employed an observational survey to assess voice navigation version A, created by visually impaired people, and voice navigation version B, created by non-visually impaired people. Thirty-two simulated visually impaired people were assigned to conduct task assessments of voice navigation version A and version B. For mission 1, the mean completion rate is 0.988 ± 0.049 (version A); the mean error rate is 0.125 ± 0.182 (version A). For mission 2, the mean completion rate is 0.953 ± 0.148 (version A); the mean error rate is 0.094 ± 0.198 (version A). The assessment results concluded that version A has a higher completion rate (p = 0.001) and a lower error rate (p = 0.001). In the assessment of subjective satisfaction, all the indicators regarding the impression of navigation directives in version A were significantly superior to those indicators in version B. It appears that version A has a different logic of framing than version B. In future applications, a voice navigation version shall be built, according to the way visually impaired people think, because it will facilitate the direction guide when there is a lack of visual feedback.

This paper argues for the use of landmarks (for example, traffic lights, churches, petrol stations) within the turn-by-turn visual and voice directions given by in-vehicle navigation systems. Such prominent features of the driving environment are consistent with basic human navigational strategies, are valued by drivers, and have been shown significantly to improve the usability of electronic in-car navigational aids. For future systems actively to include such information, it is critical that (a) only ‘good’ landmarks are used, (b) such landmarks are presented to the driver in the most appropriate way, and (c) the practical needs of industry are fully accounted for.

Purpose – Because the voice-to-technology (V2T) encounter remains under-theorised, the purpose of this paper is to overcome this gap by investigating customers use of the interactive voice response (IVR) system and “the customer journey” through the call centre service system. Design/methodology/approach – From an interpretive study of a UK call centre, the metaphorical aspects of language used to represent the service process are analysed, accompanied by an examination of how the servicescape dimensions of spatial layout and signs are constituted in the call centre service process, and the resulting implications for virtual-aural navigation. Findings – Despite no physical movement, customers represent their experience of navigating “through” the service process in spatial terms. Therefore, understanding precisely how servicescape dimensions are reconfigured within the virtual-aural setting of the call centre is necessary to appreciate customer experience of V2T but also voice-to-voice (V2V) encounters. The call centre servicescape lacks a spatial representation of layout and signs that would conventionally support navigation and purposeful movement. Research limitations/implications – Despite observing live calls, direct interaction with customers was not possible. The paper was based upon a single case study, and the hermeneutic focus on understanding and meaning meant that the study did not emphasise the quantification of phenomenon. Therefore, further research on virtual navigation is required. Practical implications – Problematic V2T encounters compromise the quality and efficiency of service provision. A visual representation of the IVR system may possibly support V2T encounters, while encouraging customer service advisors to act as “guides” during V2V encounters may reduce problems emerging from V2T encounters. Originality/value – First, an original theorisation of the customer experience of the V2T encounter is provided through the theoretical notion of spatialisation metaphors. Second, a preliminary conceptualisation of the call centre servicescape is developed, which shows how spatial layout and signs are reconfigured and represented in this virtual-aural setting.

Nowadays, navigation systems are widely used in public travel because they can instantly offer GPS-based route directions. Following the navigation prompt messages while driving is considered a secondary driving task, while vehicle control is regarded as a primary driving task. Navigation prompt messages with more information can deliver more cues to drivers, but they require a higher cognitive demand and vice versa. To systematically explore the effects of the amount of information from navigation voice prompts and further quantify the utility of voice prompts, four types of prompt messages with increasing amounts of information, denoted as a Single Message, Double Message, Triple Message, and Quadruple Message, were designed. A driving simulation experiment was conducted to obtain driving behavior data under different prompt messages. The one-way analysis of variance (ANOVA) and Kruskal–Wallis (KW) test were used to examine the differences in driving performance under the guidance of different prompt messages from multiple perspectives. Then, eight indicators were selected based on the functions of the navigation system and the driver’s response, and the grey near-optimal method was used to determine the utility of the four types of prompt messages. This study found that the four types of navigation prompt messages all began to take effect at about 200 m upstream of the stop bar. The differences between the four types of prompt messages were more significant in the zone from 100 m upstream and ended at 100 m downstream of the stop bar of the intersection. Drivers using Single and Double Messages exhibited more powerful deceleration than those using Triple and Quadruple Messages. The utility values of the four types of prompt messages increased with the increase in the amount of information. This study provides theoretical support for optimizing navigation information and lays a foundation for establishing navigation broadcast guidelines.

Modern technologies such as the Internet of Things (IoT) and physical systems used as navigation systems play an important role in locating a specific location in an unfamiliar environment. Due to recent technological developments, users can now incorporate these systems into mobile devices, which has a positive impact on the acceptance of navigational systems and the number of users who use them. The system that is used to find a specific location within a building is known as an indoor navigation system. In this study, we present a novel approach to adaptable and changeable multistory navigation systems that can be implemented in different environments such as libraries, grocery stores, shopping malls, and official buildings using facial and speech recognition with the help of voice broadcasting. We chose a library building for the experiment to help registered users find a specific book on different building floors. In the proposed system, to help the users, robots are placed on each floor of the building, communicating with each other, and with the person who needs navigational help. The proposed system uses an Android platform that consists of two separate applications: one for administration to add or remove settings and data, which in turn builds an environment map, while the second application is deployed on robots that interact with the users. The developed system was tested using two methods, namely system evaluation, and user evaluation. The evaluation of the system is based on the results of voice and face recognition by the user, and the model’s performance relies on accuracy values obtained by testing out various values for the neural network parameters. The evaluation method adopted by the proposed system achieved an accuracy of 97.92% and 97.88% for both of the tasks. The user evaluation method using the developed Android applications was tested on multi-story libraries, and the results were obtained by gathering responses from users who interacted with the applications for navigation, such as to find a specific book. Almost all the users find it useful to have robots placed on each floor of the building for giving specific directions with automatic recognition and recall of what a person is searching for. The evaluation results show that the proposed system can be implemented in different environments, which shows its effectiveness.

Abstract Wheelchairs are a very beneficial tool for commuting used by physically challenged people. But not everyone can make the wheelchair move on their own and often depend on help for movement of the wheelchair, making them dependent on constant support for every movement. Even when the physically challenged individuals are indoors, they end up being the dependent. The idea being proposed in the paper is develop a wheelchair that can make the movement of the wheelchair either automatic with inbuilt indoor navigation for easy navigation along with voice-based commands and joystick control for easy control. The wheelchair proved to be extremely beneficial for the physically challenged, at a relatively low cost.

Compared with the traditional electric-powered wheelchair, people are paying more attention on intelligent wheelchair. While the traditional intelligent wheelchair relays on separate designed control system, it is not good for general use. In that case, ROS provides an easy to use framework for rapid system development so that the researchers can develop various software packages to meet their needs, and we can also call each other packages without considering the compatibility problems. In this paper, we present a ROS (Robot Operating System) based intelligent wheelchair with the function of voice-control navigation. Compared with the traditional navigation, the voice-control navigation is more human. Obviously, ROS increases the versatility of system and reduces the cost. In order to prove the advancement and feasibility of this developed system, some experimental results are given in the paper.

Abstract There are many factors of environmental hazards that endanger the lives of personnel at radioactive waste sites after sudden extreme weather disasters, and the use of robotic substitutes can effectively safeguard the lives of personnel. For the situation where the environmental information of radioactive waste sites is unknown and there are many variables, an autonomous navigation system of emergency disposal robots with strong resilience and stability is designed. First, an algorithm based on the Rao-Blackwellized particle filtering theory is used in the autonomous navigation system to achieve more accurate robot positioning and map building through four processes: prediction, correction, resampling, and map building. Second, the traditional path planning algorithm combined with road information is added to Hopfield neural network to achieve deep analysis of complex road conditions. Finally, the intelligent voice interaction function is added to the navigation system to realize the robot’s interaction and real-time monitoring and feedback. The experimental results show that the emergency disposal robot has high accuracy in positioning, navigation, obstacle avoidance, etc., can respond quickly in unexpected situations and can carry out effective voice interaction.

Access to complex graphical information is essential when connecting blind and visually impaired (BVI) people with the world. Tactile graphics readers enable access to graphical data through audio-tactile user interfaces (UIs), but these have yet to mature. A challenging task for blind people is locating specific elements–areas in detailed tactile graphics. To this end, we developed three audio navigation UIs that dynamically guide the user’s hand to a specific position using audio feedback. One is based on submarine sonar sounds, another relies on the target’s coordinate plan x and y-axis, and the last uses direct voice instructions. The UIs were implemented in the Tactonom Reader device, a new tactile graphic reader that enhances swell paper graphics with pinpointed audio explanations. To evaluate the effectiveness of the three different dynamic navigation UIs, we conducted a within-subject usability test that involved 13 BVI participants. Beyond comparing the effectiveness of the different UIs, we observed and recorded the interaction of the visually impaired participants with the different navigation UI to further investigate their behavioral patterns during the interaction. We observed that user interfaces that required the user to move their hand in a straight direction were more likely to provoke frustration and were often perceived as challenging for blind and visually impaired people. The analysis revealed that the voice-based navigation UI guides the participant the fastest to the target and does not require prior training. This suggests that a voice-based navigation strategy is a promising approach for designing an accessible user interface for the blind.

With the development in agricultural mechanization and information technology, orchard agricultural machinery is also constantly pursuing the goal of intelligence and efficiency. Fruit picking is the most labor-intensive part of the orchard harvesting process. In order to resolve the problems of high labor intensity, low picking efficiency, and labor shortage when harvesting dwarf high-density orchards, an automatic navigation fruit-picking platform with voice control was developed in the present study. First, the platform utilized a voice-controlled high-level extendable working platform and a fruit-box-lifting device to adapt to varying orchard planting row spacing and enable convenient fruit box loading and unloading. Second, an automatic navigation system, which employed China’s Beidou navigation satellite system to acquire positional data and the Stanley algorithm for path-tracking control, was implemented. Third, the fruit-picking platform with automatic navigation system was fabricated and assembled, its outer wheel steering was measured to have a maximum angle of 30.3° and an average minimum turning radius of 4.5 m, meeting the turning radius requirements under orchard conditions. Finally, automatic navigation tests of the developed platform were performed in the orchard conditions. The results indicated that the platform could maintain a straight-line path with a maximum lateral deviation of 101.5 mm and a maximum absolute average deviation of 44.1 mm at 0.4 m/s. Under the U-shaped paths, the measured maximum lateral deviation was 148.6 mm and the maximum absolute average deviation was 57.2 mm. The navigation accuracy was sufficient to meet the requirements for the harvesting platform’s routine operation in the orchards.

Along with the development of ship navigational equipment, ship operators have to process a larger amount of information than before and be exposed to more alarm sounds. These ships’ bridge environment increases burdens to ship operators. One of the methods proposed to solve this problem is the audible voice alarm method. However, there is a lack of studies that objectively prove the efficacy of the method. Therefore, in this study, a comparative experiment was performed to confirm the effect by applying the method to an electronic chart display and information system (ECDIS), a representative navigation instrument. We analyzed collected data according to a data-driven process and confirmed the difference between a traditional alarm method and the audible voice alarm method by distinguishing groups through clustering.

Abstract The development of indoor navigation systems should utilize advanced teleinformation, geoinformation and cartographical knowledge. The authors analyzed available specifications of prototypes of indoor navigation systems and drew conclusions about how to enhance the use of cartographical methods in the whole process of designing a new system. The analysis proves that cartographical methodology is still very limited in the process of designing indoor navigation systems. Researchers focus mainly on improving the positioning accuracy, and they often neglect the issue of developing spatial databases and the rules of their effective visualization. The process of designing indoor navigation systems, just like in the case of outdoor navigation systems, consists of a number of tasks that can be supported by the theory and practice of cartography. This article presents the issues of determination of spatial database model appropriate for an indoor system, improvement of accuracy of positioning algorithms utilizing spatial data and methodology of generating graphical and voice directions for indoor navigation. In the authors’ opinion, the discussed cartographical methods and techniques may considerably enhance indoor navigation systems and accelerate their development. The fundamental knowledge of cartographical methods should be within the interest of designers of these systems. At present the first attempts in this field may be observed, although they are still not mature and complex

In this article, a new design of a wearable navigation support system for blind and visually impaired people (BVIP) is proposed. The proposed navigation system relies primarily on sensors, real-time processing boards, a fuzzy logic-based decision support system, and a user interface. It uses sensor data as inputs and provides the desired safety orientation to the BVIP. The user is informed about the decision based on a mixed voice–haptic interface. The navigation aid system contains two wearable obstacle detection systems managed by an embedded controller. The control system adopts the Robot Operating System (ROS) architecture supported by the Beagle Bone Black master board that meets the real-time constraints. The data acquisition and obstacle avoidance are carried out by several nodes managed by the ROS to finally deliver a mixed haptic–voice message for guidance of the BVIP. A fuzzy logic-based decision support system was implemented to help BVIP to choose a safe direction. The system has been applied to blindfolded persons and visually impaired persons. Both types of users found the system promising and pointed out its potential to become a good navigation aid in the future.

Visually impaired is a term for someone who has lost or reduced the function of vision. People with visual disabilities often experience difficulties in daily activities, for example when walking or navigating. They need the help of others to help them go to a room or move from one place to another. Currently, existing navigation aids do not fully meet the needs of the blind. They still need the help of others to get detailed information about visual objects such as the layout of rooms in buildings, traffic signs, and vehicles. Based on these problems, an Android-based navigation application needed that utilizes Text-to-Speech (TTS) technology to help blind people navigate independently by utilizing navigation information provided by voice. In order to help the development process, applications are developed by adopting Agile Software Development principles using the Test Driven Development (TDD) method. The features developed begin with a test fail phase where the developer creates unit test code before the production code is implemented, then refactor the code, and tests afterward (test passes). The success status of the features being tested gets success status with a rate of 100% for all features. Then in the TTS test, testing was carried out with 2 TTS engines, namely Google TTS and Samsung TTS, the results showed that the Word Error Rate (WRE) of Google TTS was 2,86, lower than Samsung TTS which got 4,06.

Considering China Beidou has unique two-way communication capability for short messages that are not available in other navigation systems such as GPS, a 600bps vocoder adapted to the short message channel of Beidou is developed. The sinusoidal excitation linear prediction algorithm is adopted by the vocoder to achieve voice communication with clear communication quality. Furthermore, a coordinate compression algorithm for processing positioning information is designed to provide more transmission space for speech encoded data. Based on the above-mentioned results, a communication system that only the Beidou navigation system is used to complete two-way secure voice and positioning simultaneous interpretation is realized. The system firstly uses a voice conversion program to convert the voice coded data obtained by the vocoder codec module into the Beidou short message data format; and then the voice code analysis program and the latitude and longitude analysis program is used to parse the voice code and location information; Finally, the experimental results of voice communication and positioning transmission are verified on the Beidou short message transceiver, and the subjective MOS test score indicates that the way is paved for the practical use of Beidou short message voice communication.

The anxiety of the humans to eradicate the difficulties of people landed up in the technological advancements. But the present scenario in India shows that navigation of blind people is a difficult task. The blind people have been using sticks and dogs for their navigation for the past decades. To make them autonomous in their mobility we put forward our idea over the existence of voice commands (IVRS).Two issues have been discussed in this paper. (i)Their navigation has been instructed by the prodigious vibroactuators which could make their mobility in a glib way [1]. The vibrations sensed through haptic perception by the blind make them to reach their destination. Voice commands will be given along with the vibrations in order to make them comfortable [2]. (ii) Our proposal proposes an idea to detect the hindrances using Ultrasonic sensors and it alerts them.The idea has been levelled up with prototype which gave the better results which has been illustrated in this paper.
