Résumé :

The paper reports on a wayfinding study aimed at identifying the information needs of the congenitally totally blind population. A route-finding experiment in a complex architectural setting was undertaken with a group of 15 congenitally totally blind and a matched control group of 15 sighted subjects. The experiment showed that, compared to the sighted control group, the blind persons planned the journey in more detail, requiring for this purpose additional environmental information. During the journey, they formulated significantly more decisions and used significantly more units of information than the sighted control. Furthermore, the nature of the information used and its source were also different for the two groups. A cognitive mapping exercise, on the other hand, showed the blind to perform virtually as well as the sighted person.

Résumé :

Early blind individuals can localize single sound sources better than sighted participants, even under monaural conditions. Yet, in binaural listening, they struggle with understanding the distances between three different sounds. The latter ability has never been tested under monaural conditions. We investigated the performance of eight early blind and eight blindfolded healthy individuals in monaural and binaural listening during two audio-spatial tasks. In the localization task, a single sound was played in front of participants who needed to localize it properly. In the auditory bisection task, three consecutive sounds were played from different spatial positions, and participants reported which sound the second one was closer to. Only early blind individuals improved their performance in the monaural bisection, while no statistical difference was present for the localization task. We concluded that early blind individuals show superior ability in using spectral cues under monaural conditions.

Résumé :

How do individuals who are blind locate, for example, the ‘@’ in an email address, the black king on a chessboard or their own house on a map? To locate information in peri-personal (non-rotated) tabletop space is a two-phase process: Phase 1 is to detect and identify the target; Phase 2 is to discover its position. This study investigated the relationship between Phase 1 and Phase 2 of the location process. A total of 23 individuals who are blind participated. Their accuracy in Phase 2 was affected by what strategy they had adopted in Phase 1; their location time was not. Three location strategies were identified in Phase 2 – the routing strategy, the global view strategy, and the touch vision strategy: the location time and accuracy not affected by which strategy had been adopted. 50% adopted the same strategy for ranking (Phase 1) target-discriminating features and (Phase 2) target-locating cues in order of importance.

Résumé :

Colours and emotions are associated in languages and traditions. Some of us may convey sadness by saying feeling blue or by wearing black clothes at funerals. The first example is a conceptual experience of colour and the second example is an immediate perceptual experience of colour. To investigate whether one or the other type of experience more strongly drives colour-emotion associations, we tested 64 congenitally red-green colour-blind men and 66 non-colour-blind men. All participants associated 12 colours, presented as terms or patches, with 20 emotion concepts, and rated intensities of the associated emotions. We found that colour-blind and non-colour-blind men associated similar emotions with colours, irrespective of whether colours were conveyed via terms (r = .82) or patches (r = .80). The colour-emotion associations and the emotion intensities were not modulated by participants’ severity of colour blindness. Hinting at some additional, although minor, role of actual colour perception, the consistencies in associations for colour terms and patches were higher in non-colour-blind than colour-blind men. Together, these results suggest that colour-emotion associations in adults do not require immediate perceptual colour experiences, as conceptual experiences are sufficient.

Résumé :

It is apparent from the historical perspective regarding the theories of cognitive development and the cognitive functioning of individuals with visual impairments, that sight plays a major role in the development of certain cognitive processes. However, the affects of visual impairment on cognitive development remain to be at issue. Since sight seems to be highly integral in cognitive development beginning in the early stages of physical development, about the sixth month of life, and then begins to diminish in importance as verbal communication develops around eighteen months, then it should stand to reason that significant visual impairment or blindness occurring prior to this time would adversely impact an individual's cognitive development. Conversely, the occurrence of visual impairment or blindness after this critical period of development would have less of an impact. Cognitive theorists have proposed that visually impaired or blind persons may have developed different cognitive pathways to acquire, process, and accommodate sensory information. As a result, visually impaired or blind (VI/B) persons may "think differently" than sighted individuals. The present study was designed to address these issues as they relate to cognitive and neuropsychological development at various stages of growth and to examine possible differences in neuropsychological functioning dependent on the level of visual functioning a person retains; e.g. both the issues of age at onset and degree of impairment. It was also designed to study the possible interaction effects of degree of impairment with the age of onset. Findings indicated that the only differences in cognitive functioning appear to be related to age of onset and not the level of visual impairment. The findings further suggested that congenitally blind individuals have indeed developed alternate methods of cognitively processing nonverbal, abstract, or complex information, especially information involving a high degree of spatial orientation. Implications of this study may influence the educational methods used to teach congenitally blind individuals in order to reinforce these alternate pathways and facilitate more effective means of negotiating in a sighted environment.

Résumé :

The incorporation of the sense of touch into virtual reality is an exciting development. However, research into this topic is in its infancy. This experimental programme investigated both the perception of virtual object attributes by touch and the parameters that influence touch perception in virtual reality with a force feedback device called the PHANTOM (TM) (www.sensable.com). The thesis had three main foci. Firstly, it aimed to provide an experimental account of the perception of the attributes of roughness, size and angular extent by touch via the PHANTOM (TM) device. Secondly, it aimed to contribute to the resolution of a number of other issues important in developing an understanding of the parameters that exert an influence on touch in virtual reality. Finally, it aimed to compare touch in virtual reality between sighted and blind individuals. This thesis comprises six experiments. Experiment one examined the perception of the roughness of virtual textures with the PHANTOM (TM) device. The effect of the following factors was addressed: the groove width of the textured stimuli; the endpoint used (stylus or thimble) with the PHANTOM (TM); the specific device used (PHANTOM (TM) vs. IE3000) and the visual status (sighted or blind) of the participants. Experiment two extended the findings of experiment one by addressing the impact of an exploration related factor on perceived roughness, that of the contact force an individual applies to a virtual texture. The interaction between this variable and the factors of groove width, endpoint, and visual status was also addressed. Experiment three examined the perception of the size and angular extent of virtual 3-D objects via the PHANTOM (TM). With respect to the perception of virtual object size, the effect of the following factors was addressed: the size of the object (2.7,3.6,4.5 cm); the type of virtual object (cube vs. sphere); the mode in which the virtual objects were presented; the endpoint used with the PHANTOM (TM) and the visual status of the participants. With respect to the perception of virtual object angular extent, the effect of the following factors was addressed: the angular extent of the object (18,41 and 64°); the endpoint used with the PHANTOM (TM) and the visual status of the participants. Experiment four examined the perception of the size and angular extent of real counterparts to the virtual 3-D objects used in experiment three. Experiment four manipulated the conditions under which participants examined the real objects. Participants were asked to give judgements of object size and angular extent via the deactivated PHANTOM (TM), a stylus probe, a bare index finger and without any constraints on their exploration. In addition to the above exploration type factor, experiment four examined the impact of the same factors on perceived size and angular extent in the real world as had been examined in virtual reality. Experiments five and six examined the consistency of the perception of linear extent across the 3-D axes in virtual space. Both experiments manipulated the following factors: Line extent (2.7,3.6 and 4.5cm); line dimension (x, y and z axis); movement type (active vs. passive movement) and visual status. Experiment six additionally manipulated the direction of movement within the 3-D axes. Perceived roughness was assessed by the method of magnitude estimation. The perceived size and angular extent of the various virtual stimuli and their real counterparts was assessed by the method of magnitude reproduction. This technique was also used to assess perceived extent across the 3-D axes. Touch perception via the PHANTOM (TM) was found to be broadly similar for sighted and blind participants. Touch perception in virtual reality was also found to be broadly similar between two different 3-D force feedback devices (the PHANTOM (TM) and the IE3000). However, the endpoint used with the PHANTOM (TM) device was found to exert significant, but inconsistent effects on the perception of virtual object attributes. Touch perception with the PHANTOM (TM) across the 3-D axes was found to be anisotropic in a similar way to the real world, with the illusion that radial extents were perceived as longer than equivalent tangential extents. The perception of 3-D object size and angular extent was found to be comparable between virtual reality and the real world, particularly under conditions where the participants' exploration of the real objects was constrained to a single point of contact. An intriguing touch illusion, whereby virtual objects explored from the inside were perceived to be larger than the same objects perceived from the outside was found to occur widely in virtual reality, in addition to the real world. This thesis contributes to knowledge of touch perception in virtual reality. The findings have interesting implications for theories of touch perception, both virtual and real.

Texte intégral

Résumé :

This study hypothesizes a greater ability by blind subjects in detecting deceptive communication from an audio channel only. Accuracy and confidence levels for the blind were compared with normally sighted undergraduate students' results. All subjects were requested to indicate their perception on several audible cues, including: speech errors, pauses, vocal segregates, response duration, vocal certainty, vocal tension, vocal pleasantness, speaking volume and rate. Subjects also indicated whether they thought the messages on the stimulus tapes were deceptive or truthful. Stimulus tapes containing deceptive statements were created by inducing a cheating incident. Undergraduate students in a lower-level communication course participated in a dot estimation task where they either performed on their own abilities or cheated with a confederate. Interviews immediately following the procedure resulted in deceptive responses from all subjects induced into cheating. A discussion of cheating as a methodology is presented in the final chapter. Results from this study indicate that blind participants tended to be more accurate at detecting deceptive communication than sighted subjects. Although vocal cues were rated similarly by both groups, the greater detection accuracy by the blind suggests sensory compensation may occur as a result of blindness. The final chapter suggests that with better measurement of audible cues used by the blind, future research may discover much about the importance of these deceptive cues.

Résumé :

This study investigated the relationship between use of Light Rapid or Light Rail (LRT) by persons with severe visual impairments and independence in orientation and mobility. Use of the LRT poses special problems to blind users and requires skill in mobility. The premise of the study was that blind persons who felt confident in travelling independently were more likely to use the LRT than those who do not. The study also examined the difficulties blind persons experienced in LRT use. The subjects were 63 persons between the ages of 19 and 65 who responded to a survey questionnaire. Thirty five of these individuals were male and 25 were female. All the subjects were registered as legally blind with the C.N.I.B. The range of visual loss included total blindness, light perception, tunnel vision, central vision loss and low vision. The results indicated that orientation and mobility training on the LRT system would resolve many of the difficulties that users of the systems encountered. Modification of the systems by transit companies to make the systems more easily accessible to visually impaired travellers are suggested.

Résumé :

This qualitative study investigated the remembered lived experiences of six individuals who were diagnosed with Usher syndrome, the effect that the progressive condition had upon their lives, and their experiences with vocational rehabilitation. Usher syndrome is an autosomal recessive condition that presents as deafness or hearing loss with comorbid retinitis pigmentosa sometimes with vestibular areflexia. The participants recalled details of their own reaction to the diagnoses as well as the reactions of their parents. Themes were identified in their responses that included independent dependence, Usher support, parental reaction, lowered expectations, hope, and ongoing change. The participants, three men and three women, reported periods of adjustment and sadness as well as hopes for their future, career accomplishments, and social interactions.

Texte intégral

Résumé :

Vocabulary acquisition plays an important role in second language students’ performance. In the process of learning vocabulary, students are exposed to different sorts of input that might affect the way their working memory processes, retains, and recalls the new information they are exposed to, which can be visual, auditory, haptic, or multimodal (Paivio, 1991). Research has been extensively done on the effects of input modality on working memory in L1 word recall tasks in individuals with normal development and also in individuals with visual disabilities; however, no attention has been given to the effects of input modality on working memory in word recall tasks in blind individuals in the realm of second language learning. The current research sought to investigate the effects of input modality on working memory in L2 word recall tasks with the goal of determining if the lack of access to visual stimuli would have any substantial effects on L2 word retention and recall. It was predicted that participants would do better on those word recall tasks that involved the use of more than one modality simultaneously and that lack of access to visual stimuli would not negatively affect L2 word recall. To address these issues, we devised two word recall experiments: experiment 1 for the blind participant of the study (a 24 year old female graduate student who is an English native speaker), and experiment 2 for the sighted participants. Both experiments comprised a Digit Span Test, 4 word recall tasks in which participants were exposed to four different lists of high frequency Spanish words and their English translations in different modalities (Oral, Written (Braille), Oral+Written (Braille), Haptic/visual+Oral), and an interview. Thirty (16 females, 14 males) American English Native speakers who were sighted with ages ranging from 19 to 37 participated in this study; half of them were blindfolded for the last word recall task (Haptic+Oral). The results for both experiments showed that contrary to our predictions and to what dual coding theories claim, our participants were able to recall more words in those tasks that involved the use of only one modality. In part this may be attributed to 1) the fact that it was the first time these participants were exposed to Spanish vocabulary and so it made it more difficult for their working memories to integrate modalities and 2) an information overload since the stimulus words were presented with their translation. Moreover, the lack of access to visual stimuli did not have a strong effect in those participants who were blindfolded, which may be explained by the fact that the oral and haptic input triggered the use of mental imagery when retaining and recalling the words. Finally, the practical and pedagogical implications of the findings of the present study, as well as recommendations for the future research are discussed.

Résumé :

When people go to a mall, museums, or other such locations they tend to rely on maps to find their way around. However, for people who are blind or visually impaired (BVI) maps are not easily accessible and they depend on other means, such as a guide, to get around. Research has only just begun to investigate providing maps for people who are BVI on touch screen devices. Many different types of feedback have been used: audio (sound), tactile (touch), audio-tactile, and multitouch. Some research has been conducted on the benefit of using multiple fingers (multitouch) and has found conflicting results. Yet, no known research has been conducted on the comparison of using audio feedback to that of tactile feedback. In this study, we look to try and answer two questions. 1.) Is audio equal to or better than tactile? As well as: 2.) Does multiple fingers help? Participants were asked to use seven different methods (4 audio, 3 tactile) to explore an overview map and an individual map and answer questions about them. Results showed that overall, audio cues are similar or better than tactile cues which is beneficial since it requires less battery to generate audio cues than tactile cues. It was also shown that the use of multiple fingers was more beneficial in tasks that are spatially demanding. While those who have tactile experience benefited when using two fingers with each finger represented by a different instrument played to separated ears.

Résumé :

The purpose of this research project was to explore how field experience can be used to increase understanding and researcher behaviours in young adults who are blind or visually impaired. This study probed effective teaching methods and solutions to accessibility issues through high-level participation in a field ecology research setting involving marine mammals. The weeklong program was executed in a pre-existing long-term gray whale ecology research site in Clayoquot Sound, British Columbia. Four research questions guided the overall planning of the program. The concentration of effort was applied to adapting the field site and equipment in order for students to use and access the resources during planned multisensory activities. Three post-secondary students spent a week in the field becoming active marine mammal researchers. Data for this study were gathered through a variety of qualitative methods including vocabulary checklists, journal writing, a group case study and questionnaires. The results of this program have implications for educational opportunities by highlighting how addressing and offering learning tools that appeal to a variety of learners can create new and vital opportunities for students who are visually impaired.

Résumé :

The research presented in this thesis addresses the neural mechanisms of auditory motion processing and the impact of early visual deprivation on motion-responsive brain regions, by using functional magnetic resonance imaging. Visual motion, and in particular direction selectivity, is one of the most investigated aspects of mammalian brain function. In comparison, little is known about how the brain processes moving sounds. More precisely, we have a poor understanding of how the human brain codes for the direction of auditory motion and how this process differs from auditory sound-source localization. In the first study, we characterized the neural representations of auditory motion within the Planum Temporale (PT), and how motion direction and sound source location are represented within this auditory motion responsive region. We further explore if the distribution of orientation responsive neurons (topographic representations) within the PT shares similar organizational features to what is observed within the visual motion area MT/V5. The spatial representations would, therefore, be more systematic for axis of motion/space, rather than for within-axis direction/location. Despite the shared representations between auditory spatial conditions, we show that motion directions and sound source locations generate highly distinct patterns of activity. The second study focused on the impact of early visual deprivation on auditory motion processing. Studying visual deprivation-induced plasticity sheds light on how sensory experience alters the functional organization of motion processing areas, and exploits intrinsic computational bias implemented in cortical regions. In addition to enhanced auditory motion responses within the hMT+/V5, we demonstrate that this region maintains direction selectivity tuning, but enhances its modality preference to auditory input in case of early blindness. Crucially, the enhanced computational role of hMT+/V5 is followed by a reduced role of PT for processing both motion direction and sound source location. These results suggest that early blindness triggers interplay between visual and auditory motion areas, and their computational roles could be re-distributed for effective processing of auditory spatial tasks. Overall, our findings suggest (1) auditory motion-specific processing in the typically developed auditory cortex, and (2) interplay between cross- and intra-modal plasticity to compute auditory motion and space in early blind individuals.

Résumé :

AbstractThis paper addresses the issue in live events, especially in sports viewing, where individuals who are deaf, hard of hearing (DHH), blind, or have low vision (BLV) struggle to access sufficient information. Traditionally, information accessibility has relied on specific professionals or volunteers, which is often inadequate. To tackle this challenge, we propose a mechanism that facilitates information sharing for all individuals, regardless of their abilities. We have developed an inclusive web application tailored to address these needs. This application is beneficial not only for DHH and BLV individuals but also for all audiences. Additionally, the system’s applicability extends to other domains, such as museum visits. This paper details the newly developed web application and presents the outcomes of pilot studies conducted in sports viewing and museum settings with DHH and BLV participants. The results of these experiments are analyzed to assess the system’s effectiveness and to identify future improvement areas.

Résumé :

Accurate characterization of fleet and individual aircraft usage spectrums would allow component retirement times to be based on actual aircraft usage rather than on an assumed worst case usage spectrum used in a traditional time-based maintenance approach. A key enabling technology for such a Usage or Condition Based Maintenance (UBM/CBM) program is Regime Recognition (RR). The development and validation of such algorithms commonly employs flight loads survey data, which captures critical regimes and the corner points of the operational envelope. Such maneuver examples are flown precisely and don’t necessarily capture how fleet aircraft are flown. The maneuver generation approach presented herein presents the foundational elements of a methodology to augment existing flight loads survey data with statistically independent maneuvers that address the desire to capture the variation that would be observed in the fleet as a result of different pilots, vehicle load-out, and environmental conditions via a simulation based autopilot. Such a capability allows developers to cost-effectively conduct comprehensive sensitivity analyses and verification of RR algorithms and the end-to-end process, while reserving high-cost flight test data for true blind validation.

Texte intégral

Résumé :

Religious identity is critically important to consider in assessing patterns of displacement and the dynamics of conflict and peace-building, as well as programmatic and policy responses to humanitarian crises. Conflicts are frequently driven by discrimination and generate massive numbers of refugees and internally displaced persons (IDPs) as they flee from persecution and violence, whilst individuals or groups may be targeted for their identity or face insecurity during community activities. As a result, the relationship between diversity, inclusivity, and interdependence is key to developing approaches that address intersecting forms of insecurity experienced by religious minorities. This paper reviews current thinking and policy directions in understanding religious inequalities in humanitarian contexts and asks the following questions: 1) What are the implications of programming that is blind to religious inequalities? 2) How can humanitarian actors incorporate sensitivity to religious difference and persecution in their programming, and what are the challenges of doing so?

Texte intégral

Résumé :

This is one of the first studies in Sweden testing the notion of racial color-blindness empirically in a Swedish context, by asking a sample of Swedish participants to assign race to images of faces with different phenotypes, rate how ‘Swedish’ the faces are perceived (referred to the degree of ‘Swedishness’) and identify the skin color of the faces (through the NIS skincolor scale). We also use eye-tracking to explore whether participants look differently at faces of different racial groups. The results show that skin-color is a decisive factor in the racial ascription as Black, while skin color is not determinant of the degree of Swedishness. What determines the degree of Swedishness is the racial assignment itself, in other words, how individuals perceive and categorize phenotypes into different racial groups. We conclude that Swedes are not truly racially color-blind and race does indeed matter in Sweden.

Résumé :

The toolkit consists of two modules that guide modeling practices or training delivery, including recommendations for training format, duration, and breaks. It is organized to support typical water modeling processes and includes practical guides, tips for further learning, examples, and practice exercises for individuals or groups to achieve GEDSI in water modeling. The toolkit aims to help users: Understand the benefits of incorporating Gender Equality, Disability, and Social Inclusion (GEDSI) into water modelling, recognizing its value in addressing complex water management challenges. Comprehend the negative impacts of GEDSI-blind modelling, which can perpetuate disparities and biases in water management. Build confidence in integrating GEDSI considerations into modeling practices by acquiring the necessary skills and knowledge. Identify strategic GEDSI entry points in the modeling process, such as data collection, analysis, interpretation, model development, and scenario modeling. Develop proficiency in gathering and analyzing GEDSI-disaggregated data and using GEDSI-aware modeling techniques. Gain skills to develop and model scenarios that promote GEDSI and evaluate their potential impacts. The primary audience includes hydrologists, water resources engineers, water managers, and policymakers who use modeling extensively. Other stakeholders, such as those in GEDSI, social science, community representation, agriculture, and disaster risk management, may also find the toolkit useful.

Texte intégral

Résumé :

Industry is directing efforts toward reducing the environmental impact of operation through improving pipeline performance and addressing evolving regulatory requirements. As a result, external leak detection technologies have been recently developed; however, it is challenging to test these systems with real hydrocarbon products in-situ. This research project was developed to assess these external leak detection technologies' abilities to identify the presence of hydrocarbon products on the surface of water. In the first phase of the project, testing was limited to an idealized freshwater environment under ambient conditions. The second phase, described herein, was expanded to a freshwater environment under freezing conditions, where the surface of the water has frozen over. Testing was performed by releasing each test fluid (diesel, Synthetic Sweet Blend and Access Western Blend) into basins containing individual sensors. Releases were performed above the ice surface, below the ice surface, and onto the water surface after freeze/thaw cycles. Each sensor's response to contact with the test fluid was monitored and compared based on time to detection and estimated slick thickness at detection.
