E-navigation poses significant challenges for shipping. The analysis of the legal norms in the International Regulations for Preventing Collisions at Sea (COLREGS) and court decisions supports the use of information technology on the bridge for the purpose of improving navigational safety. However, the current regulatory and standardisation requirements hamper the introduction of new information streams in navigational systems and remove the incentives for investment in navigation technology. The liability arising from navigational failures will remain on the employer of the crew irrespective of how the additional navigational information is provided to the navigational systems. The shipowner's liability may depend on the way information streams are provided to the ship only within the context of the Civil Liability Convention (CLC) 1992 and other similar pollution conventions where the characterisation of the navigational system as a navigational aid or an aid to navigation may decide the issue of liability. Research on the legal background of these terms underlines the need for a clear distinction between the two terms to be made. An interpretation is proposed which ensures that the CLC liability exception operates in accordance with the underlying legal requirements.

This paper presents the exploitation of Wi-Fi signals sensors using fingerprinting method to capture the location and provide the possible navigation paths. Such approach is practical because current smartphones nowadays are equipped with inertial sensors that can capture the Wi-Fi signals from the Wi-Fi’s access points inside the building. From the comparative study conducted, the AnyPlace development tool is used for the development of dynamic navigation indoor map. Its components, namely; Architect, Viewer, Navigator and Logger are used for different specific functions. As a case study, we implement the proposed approach to guide user for navigation in Sunway Pyramid Shopping Mall, Malaysia as floor plan as well as using Google Maps as the base map for prove of concept. From the developer point of view, it is observed that the proposed approach is viable to create a dynamic navigation indoor map provided that the floor plans must be generated first. Such plan should be integrated with the SDK tool to work with the navigation APIs. It is hoped that the proposed work can be extended for more complex indoor map for better implementation.

Based on traditional expressions and spherical trigonometry, at present, great circle navigation is undertaken using various navigational software packages. Recent research has mainly focused on vector algebra. These problems are calculated numerically and are thus suited to computer-aided great circle navigation. However, essential knowledge requires the navigator to be able to calculate navigation parameters without the use of aids. This requirement is met using spherical trigonometry functions and the Napier wheel. In addition, to facilitate calculation, certain axioms have been developed to determine a vessel’s true course. These axioms can lead to misleading results due to the limitations of the trigonometric functions, mathematical errors, and the type of great circle navigation. The aim of this paper is to determine a reliable trigonometric function for calculating a vessel’s course in regular and composite great circle navigation, which can be used with the proposed axioms. This was achieved using analysis of the trigonometric functions, and assessment of their impact on the vessel’s calculated course and established axioms.

Electronic Chart Display and Information Systems (ECDIS) technology has recently emerged as a promising aid to maritime navigational safety and operational efficiency. ECDIS is likely to have multiple effects on the tasks bridge personnel must perform. However, careful consideration must be given to safety in adopting this new technology. A shiphandling simulator-based evaluation of some human factors aspects of the use of ECDIS is presented. The issues discussed include the effect on navigational safety and workload as a result of introducing ECDIS to the bridge, and the mariner's preference for and use of chart information and navigational data. Experienced mariners each made multiple port arrivals and departures as the lone watchstander on the bridge: navigating a planned route, responding to harbor traffic, and managing the preparations for arrival or departure. During “baseline” transits, conventional methods were available to the mariner. During the test scenarios, one of two prototype ECDIS systems was also added to the bridge. Under certain conditions, ECDIS reduced the mariner's workload for navigation. In addition, ECDIS showed a potential to increase safety as measured by a smaller cross-track distance from the planned route and by a larger proportion of time available to devote to collision avoidance and “look out”.

Background. Augmented reality (AR) glasses with GPS navigation represent the rapidly evolving technology which spares (and externalizes) navigational capacities. Regarding the expected everyday usage of this device, its impact on neuroplastic brain changes and navigation abilities should be evaluated. Aims. This study aimed to assess possible changes in functional connectivity (FC) of hippocampus and other brain regions involved in spatial navigation. Methods. Thirty-three healthy participants completed two resting state functional magnetic resonance imaging (rsfMRI) measurements at the baseline and after 3 months. For this period, the experimental group (n = 17) has had used AR device (Vuzix M100) with incorporated GPS guidance system during navigation in real world. Participants from the control group (n = 16) have not used any GPS device while navigating during walking. The rsfMRI FC of right and left hippocampi was analyzed using a seed-driven approach. Virtual city task was used to test navigational abilities both before and after the usage of AR device. Results. We identified strong functional coupling of right and left hippocampi at the baseline (p < 0.05, FDR corrected). Mild changes in bilateral hippocampal FC (p < 0.05, FDR uncorrected) were observed in both assessed groups mainly between the bilateral hippocampi and between each hippocampus and temporal regions and cerebellum. However, the experimental group showed FC decrease after three months of using GPS navigation implemented in AR glasses in contrast to FC increase in the control group without such intervention. Importantly, no effect of intervention on navigational abilities was observed. Discussion. Our observation supports the assumption that externalization of spatial navigation to technological device (GPS in AR glasses) can decrease the functional coupling between hippocampus and associated brain regions. Considering some limitations of the present study, further studies should elucidate the mechanism of the observed changes and their impact on cognitive abilities.

Underwater positioning and navigation is a technology that provides the attitude, speed, position and other information of underwater robots. It is the premise for underwater robots to successfully complete various underwater tasks. The underwater environment is complex and changeable, and a single positioning and navigation technology will inevitably not meet the needs of long-range, multi-target and high-precision. The navigation system of the future underwater intelligent robot integrates the integrated navigation mode of various technologies. This paper discusses the basic underwater positioning and navigation mode and integrated navigation mode, describes the development process of underwater positioning and navigation technology, compares the research methods and progress of Chinese and foreign scholars, analyzes the current research bottlenecks and technical difficulties, and points out the direction for future research, which can be used as a reference for the follow-up research of underwater robot positioning and navigation system.

Background: Sarah Cannon has established a standardized nurse navigation program for breast, lung, and Gi cancer patients. Navigators play a significant role in addressing barriers that may adversely impact patient outcomes. Historically, nurse navigators were spending up to 65% of their time data mining to identify new patients for navigation. This lost time compromises a navigator’s ability to effectively support patients. Sarah Cannon implemented a technology solution to address this manual process. Methods: A patient identification software application (patient ID), utilizing natural language processing technology, was developed to identify positive pathology reports across the enterprise in real time. Patient ID instantly routes those reports to a tumor site-specific oncology nurse navigator. The impact of this technology was assessed in 3 Hospital Corporation of America (HCA) markets from December 2016–March 2017. Total patient recall, total volume of reports reviewed, navigated patient volumes, navigator time allocation, and time from diagnosis to first treatment were studied. Results: Patient ID reviewed 47,544 pathology reports during the 4-month pilot, identifying 7,224 potential cancer reports. 2,782 of those represented breast, lung, or Gi cancer patients and were routed to a nurse navigator. Patient ID performed with an overall total patient recall of 98%, respectively. Decreased time spent data mining was observed, and navigator caseload increased by 71%. Time from diagnosis to first treatment decreased by an average of 6 days. Time allocated to direct patient contact and physician interaction increased by 35%. Conclusions: Implementation of a technology solution to rapidly identify new cancer patients for navigation in a community health system is feasible and associated with multiple benefits. Increased navigator patient volumes and navigator productivity were observed. Navigator time spent with patients and physicians increased with a concurrent reduction in data mining time. Timeliness of care metrics improved, suggesting a favorable impact on quality. This technology is now being deployed across the HCA enterprise.

The use of blind-aided navigating systems has become very essential in the 4th industrial revolution. The essence of this is to improve navigating autonomy for the blind. Although, navigation challenges are not of serious concern to people with eye defects. However, this is a major concern for blind people due to the time-consuming navigation process. These limitations necessitate the use of walking sticks, dogs, or people to navigate their path. This project provides a blind navigation system based on Light Detection and Ranging Based Navigation System for Blind People (LiDAR). The components of this fabricated device involve a charging system, a LiDAR sensor, a microcontroller, a calling stick, two buzzers, a switch vibration motor with an RF transmitter, and a receiver to give object detection and real-time assistance to the blind. The mode of its operation is by detecting obstacles along the route of a blind person and giving a notification via the buzzer and the vibration motor. Also, during emergencies, the buzzer rings and informs the visually impaired person using the device. On the other hand, the microcontroller and other modules in the device have a continuous ongoing relationship which is beneficial to the user. Another appreciable benefit of this device is the ability to recharge the battery component, the device is of low-cost, quick, simple-to-use, and novel solution for the blind.

People have always relied on some form of instrument to assist them to get to their destination, from hand-drawn maps and compasses to technology-based navigation systems. Many individuals these days have a smartphone with them at all times, making it a common part of their routine. Using GPS technology, these cellphones offer applications such as Google Maps that let people find their way around the outside world. Indoor navigation, on the other hand, does not offer the same level of precision. The development of indoor navigation systems is continuously ongoing. Bluetooth, Wi-Fi, RFID, and computer vision are some of the existing technologies used for interior navigation in current systems. In this article, we discuss the shortcomings of current indoor navigation solutions and offer an alternative approach based on augmented reality and ARCore. Navigating an indoor environment is made easier with ARCore, which brings augmented reality to your smartphone or tablet.

The issues of cybernetic security are considered in the aspect of effective proposals of alternatives to the satellite system in order to be able to promptly reorient to a backup positioning system in case of any technical problems. The assessment of the use of computer-specific competencies in the field of information technologies of the marine fleet as a secondary factor of end-to-end cybernetic security management is given. Information processing in a duplicate analogue of the positioning system is based on the technology of spline functions in order to extract the advantages of piecewise approximation for practical navigation purposes. The functionality of the navigator is analyzed within the framework of the «augmented reality technology» of the bridge of the future with the possibility of observational fixation of the look of the watch officer based on improved virtual professional scenarios against the background of the flow of typical navigation information. In addition to alternatives to the traditional positioning system, the requirements of space all-weather, system noise immunity and round-the-clock use in emergency situations, military conflicts and man-made disasters are formulated. In the circumstances of uncertainty of satellite systems, the problems of their vulnerability are theoretically leveled due to the intended use of navigation equipment based on other physical principles of operation. Correlation-extreme navigation through natural geophysical fields, the innovative e-LORAN project and the means of celestial navigation automated on the basis of computing resources of the onboard computer are highlighted as promising variants of the autonomous positioning principle. The research carried out in this work is combined with the results of experiments within the framework of the magnetic navigation project on the practical implementation of autonomous aviation positioning. Validation of the characteristics of the isotropic field as an informative standard of correlation-extreme navigation is confirmed by practical implementations of various fragments of geophysical fields in the form of three-dimensional visualizations of spline synthesis. The accuracy of geolocation with «terrain-referenced navigation» by extreme indicators is analysed. The forecast of achievability of the predictability effect of a mobile object location in a satellite-based environment is given with optimal motion control using predictive modeling, provided that an accurate assessment of the uncertainty of the navigation system is foreseen. The algorithms tested on the methods of spline functions to ensure authoritative positioning are performed as an intellectual support for the ship’s management staff in an emergency situation.

The technology breakthrough that Electronic Chart Display and Information System (ECDIS) has brought to modern navigation has the capability to improve the safety of navigation. This could be achieved only when the capabilities of the system are known by an end-user. Cross Track Limit (XTL) is an ECDIS safety parameter, set by the navigator, which enhances the navigational task automation in the function of workload reduction. Determination of factors affecting the value of XTL safety parameter, with special consideration to chart data reliability, is elaborated in this paper. Chart data reliability depends on the quality of chart survey data, which in many cases are outdated and unreliable. Analysis of past research on this subject is used to define the factors affecting XTL. Practices of different shipping companies with regards to XTL are analyzed and compared in order to confirm if there is a uniform practice between them. Nevertheless, shipping companies have a different or no practice of obtaining XTL, which allows the navigator to define safety parameters by a subjective opinion. In this paper, method of XTL determination for a specific vessel is suggested, considering previously defined factors. Finally, crucial influence of survey data to the safety of navigation is presented in this study.

Blockchain technology brings new possibilities in assisted spatial navigation. Decentralized map building enables collaboration between users around the world, while providing researchers with a common reference map for extending the capabilities of navigational systems towards more intuitive and accurate landmark navigation assistance. Research on landmark navigation has been mainly focused on the visual characteristics of landmarks. Human behavior, however, has systematically been shown to be enhanced in the presence of multisensory unified events. We propose, therefore, the enhancement of spatial assisted navigation by utilizing landmarks that are multisensory and semantically congruent. Further, our research will provide insights in terms of the auditory parameters that could be combined with a given visual landmark, so as to facilitate landmark retrieval algorithms and user satisfaction during assisted spatial navigation.

Abstract In the 21st century marine navigation has become dominated by satellite positioning systems and automated navigational processes. Today, global navigation satellite systems (GNSS) play a central role in the process of carrying out basic navigational tasks, e.g. determining the coordinates of a vessel’s position at sea. Since satellite systems are being used increasingly more often in everyday life, the signals they send are becoming more and more prone to jamming. Therefore there is a need to search for other positioning systems and methods that would be as accurate and fast as the existing satellite systems. On the other hand, the automation process makes it possible to conduct navigational tasks more quickly. Due to the development of this technology, all kinds of navigation equipment can be used in the process of automating navigation. This also applies to marine radars, which are characterised by a relatively high accuracy that allows them to replace satellite systems in performing classic navigational tasks. By employing M-estimation methods that are used in geodesy as well as simple neural networks, a software package can be created that will aid in automating navigation and will provide highly accurate information about a given object’s position at sea by making use of radar in comparative navigation. This paper presents proposals for automating the process of determining a vessel’s position at sea by using comparative navigation methods that are based on simple neural networks and geodetic M-estimation methods.

Healthcare has a trend of going hi-tech. With an aging population growing more than ever, researchers and health care providers are now relying on robots to ease the symptoms of dementia and help an aging population stay where they would like, at home. Several therapeutic robots such as Paro recently introduced in the markets are manifestation of such trends. In this paper, we propose a social robot missioned to autonomously capture images of people and feed multimedia contents to a social network or to a hospital for various social activities or for health monitoring purpose. The main technical barriers of such robots include autonomous navigation, human face detection, distance, and angle adjustment for clean and better shots. To that end, we study autonomous mapping/navigation as well as optimal image capturing technology via motion planning and visual servoing. To overcome the mapping and navigation at a crowded environment, we use the potential field path planning harnessed with two competitive potential update techniques. The robot is an agent navigating in a potential field where detected environmental significances provide sources of attractive forces, while previously occupied locations estimated by SLAM technique provide sources of repelling forces. We also study visual servo technique to optimize image capturing processes. This includes facial recognition, photographic distance/angle adjustment, and backlight avoidance. We tested several scenarios with the assembled robot for its usefulness.

All ships need navigation data to ensure they stay on track during course-changing maneuvers. Navigation data are usually obtained by shipyards while conducting turning trials at sea. The aim of this research was to generate navigation data for warships, such as the Leander Class Frigate (LCF). The research was conducted using the Ship Bridge Simulator (SBS) simulation technology at the Maritime Centre of the National Defence University of Malaysia (NDUM). Turning trials were conducted at various speeds, rudder angels, and heading changes. Distance to new course, advance and transfer have been tabulated for LCF navigation data. Navigation experts validated the data by nautical chart plotting. The data were found to be highly reliable for the training module. The research was successfully conducted and generated LCF navigation data. The navigation data collected are highly accurate and effective for the naval cadet navigation training module at the NDUM. The SBS software is highly suitable for turning trials and navigation data generation.

A user-controlled navigation system is one of the important aspects of human-computer interaction. Finding best path from one location to another and navigating through that path has been a great concern in the geo-virtual navigation. Earlier studies on the geo-virtual navigation systems mainly focus on navigation and visualization, but lack in geo-spatial analysis. Geo-spatial analysis is the domain of geographic information systems (GIS) in which 3D geo-spatial information is used for navigation, geo-visualization, and geo-spatial analysis. The present study deals with wayfinding in the road network of the campus of National Institute of Technology (NIT) Hamirpur, India, in a hilly terrain. It facilitates perform various types of geo-spatial analyses on the road network and virtual travelling in a 3D space.

Dynamic Navigation is a computer-aided technology that allows the surgeon to track the grip instruments while preparing the implant site in real time based on radiological anatomy and accurate pre-operative planning. The support of this technology to the zygoma implant placement aims to reduce the risks and the errors associated with this complex surgical and prosthetic treatment. Various navigation systems are available to clinicians currently, distinguished by handling, reliability, and the associated economic and biological benefits and disadvantages. The present paper reports on the different protocols of dynamic navigations following a standard workflow in correlation with zygomatic implant supported rehabilitations and describes a case of maxillary atrophy successfully resolved with this technology. An innovative and minimally invasive dynamic navigation system, with the use of an intraoral anchored trust marker plate and a patient reference tool, has been adopted to support the accurate insertion of four zygomatic implants, which rapidly resolved maxillary atrophy from a 75-year-old male system. This approach provided an optimal implant placement accuracy reducing surgical invasiveness.

Abstract: GPS and Inertial Navigation Systems (INS) are used today in automobile navigation and tracking systems to locate themselves in Four Dimensions (latitude, longitude, altitude, time). However, GNSS or GPS still has its own bottleneck, such as the long initialization period of Precise Point Positioning (PPP) without dense reference network. For navigation, a number of selected LEO satellites can be equipped with a transmitter to transmit similar navigation signals to land users, so they can act like GNSS satellites but with much faster geometric change to enhance GNSS capability, which is named as LEO constellation enhanced GNSS (LeGNSS). This paper focuses on Low Earth Orbit navigation and anti-theft tracking system in automobiles that represents a framework which enables a navigating vehicle to aid its Inertial Navigation System when GNSS or GPS signal becomes unusable. Over the course of following years LEO satellite constellation will be available globally at ideal geometric locations. LEO Satellite aided Inertial navigation system with periodically transmitted satellite positions has the potential to achieve meter-level-accurate location. Keywords: LEO constellation, LEO enhanced GNSS (LeGNSS), Precise Point Positioning (PPP), Inertial Navigation System (INS), Precise Orbit Determination (POD)

Any user can navigate outdoors by using online maps with the help of a GPS signal, but navigation in an indoor environment is difficult as the GPS signals can be weak inside a building. In this article, a system for providing a solution for indoor navigation with the help of augmented reality technology based on a computer vision approach is developed so as to provide navigational assistance to users in any new or unknown environment. This is done with an android based mobile phone application. This can be done by using augmented reality technology along with a computer vision-based approach to find where the user is and what is present in front of the user. Using this information, the user can get to navigate inside the building.

The integration of navigation and communication technologies can be divided into three levels: system level, terminal level and the signal level. The integration technology of satellite communication and navigation is introduced briefly at first. Then the combination of communication and navigation functions at the signal level is analyzed and researched in depth. A novel idea is proposed that pseudo-range measurement and positioning can be achieved while keeping the existing communication functions, only by adding positioning related information. Finally, application of communication and navigation signal integration is prospected.

Prior work on AI-enabled assistive technology (AT) for people with visual impairments (VI) has treated navigation largely as an independent activity. Consequently, much effort has focused on providing individual users with wayfinding details about the environment, including information on distances, proximity, obstacles, and landmarks. However, independence is also achieved by people with VI through interacting with others, such as through sighted guiding in navigation. Drawing on the concept of interdependence, this research aims to (1) present an exemplary case of interdependence and draw out important implications for designing AI-enabled AT; (2) propose and evaluate a prototype that enhances social interactions in sighted guiding and aids navigation.
