Navigation assistive technologies have been designed to support individuals with visual impairments during independent mobility by providing sensory augmentation and contextual awareness of their surroundings. Such information is habitually provided through predefned audio-haptic interaction paradigms. However, individual capabilities, preferences and behavior of people with visual impairments are heterogeneous, and may change due to experience, context and necessity. Therefore, the circumstances and modalities for providing navigation assistance need to be personalized to different users, and through time for each user. We conduct a study with 13 blind participants to explore how the desirability of messages provided during assisted navigation varies based on users' navigation preferences and expertise. The participants are guided through two different routes, one without prior knowledge and one previously studied and traversed. The guidance is provided through turn-by-turn instructions, enriched with contextual information about the environment. During navigation and follow-up interviews, we uncover that participants have diversifed needs for navigation instructions based on their abilities and preferences. Our study motivates the design of future navigation systems capable of verbosity level personalization in order to keep the users engaged in the current situational context while minimizing distractions.
An Independent and Interactive Museum Experience for Blind People
Museums are gradually becoming more accessible to blind people,
who have shown interest in visiting museums and in appreciating
visual art. Yet, their ability to visit museums is still dependent on
the assistance they get from their family and friends or from the museum personnel. Based on this observation and on prior research, we
developed a solution to support an independent, interactive museum
experience that uses the continuous tracking of the user’s location
and orientation to enable a seamless interaction between Navigation
and Art Appreciation. Accurate localization and context-awareness
allow for turn-by-turn guidance (Navigation Mode), as well as detailed audio content when facing an artwork within close proximity
(Art Appreciation Mode). In order to evaluate our system, we installed it at The Andy Warhol Museum in Pittsburgh and conducted
a user study where nine blind participants followed routes of interest
while learning about the artworks. We found that all participants
were able to follow the intended path, immediately grasped how
to switch between Navigation and Art Appreciation modes, and
valued listening to the audio content in front of each artwork. Also,
they showed high satisfaction and an increased motivation to visit
museums more often

Informal science learning spaces such as museums have been exploring the potential of Augmented Reality (AR) as a means to connect visitors to places, times, or types of content that are otherwise inaccessible. This proposal reports on a design-based research project conducted at La Brea Tar Pits, an active paleontological dig site located within a city park in the heart of Los Angeles. The Natural History Museums of Los Angeles County and the University of Southern California engaged in a research practice partnership to enhance place-based science learning through the design and iterative testing of potential AR exhibits. Results from one implementation show that AR technology increased visitor interest in the park and positive emotions around science content. Significant learning gains and decreases in science misconceptions also occurred for participants. We also give guidance on developing scientifically accurate assets for AR experiences and leading users through a virtual narrative. This presentation offers insights into museum and university partnerships for promoting public understanding of science in informal spaces by leveraging place-based learning through technology-enhanced engagement. https://mw21.museweb.net/proposal/tar-ar-bringing-the-past-to-life-in-place-based-augmented-reality-science-learning/

Informal learning settings such as museums provide unique opportunities for educating a local community about sleep. However, in such settings, information must be capable of immediately inciting interest. We developed a series of sleep “icebreakers” (brief, informal facts) to determine whether they elicited interest in sleep and encouraged behavioural change. There were 859 participants across three cross-sectional samples: (a) members of the local museum; (b) Mechanical Turk workers who responded to a “sleep” study advertisement; and (c) Mechanical Turk workers who responded to a “various topics” study advertisement that did not mention sleep. All three samples demonstrated high interest in sleep topics, though delayed recall of the icebreakers was strongest in participants who expected to learn about the sleep topics. Icebreaker interest ratings were independent of age, gender and race/ethnicity, suggesting that sleep is a topic of universal interest. Importantly, regardless of demographics and sample, the more the icebreakers interested the participants, the more likely participants were to indicate willingness to donate to a sleep exhibit, change their sleep behaviours, and post to social media. Thus, sleep icebreakers can rapidly elicit people's interest, and future outreach efforts should couple icebreakers with opportunities for subsequent personalized learning.

Participating in a research experience for undergraduates (REU) site provides opportunities for students to develop their research and technical skills, network with other REU students/professors, raise their awareness of graduate studies, and understand the social context of research. In support of this mission, our REU site at the University of Alabama is exploring research at the intersection of engineering and communicative disorders. Beyond research training though, an REU site provides the opportunity for professional development, social activities, and cultural activities to enrich the student experience. These are important features of an REU, which typically range from 9-10 weeks. Students that participate in summer REUs are recruited from around the country and are brought together at a central research site. Each student brings with them their unique perspectives and lived experiences. To form a cohesive cohort from the individual students, it is important to facilitate shared experiences early in their 9-10 week REU. Supporting the development of a student community through shared experiences has a significant impact on student perspectives of the program. Shared experiences also provide the opportunity to increase the students’ understanding of the new city/state/region that is the setting for the REU. The 2019 iteration of our REUmore »

GPS accuracy is poor in indoor environments and around buildings. Thus, reading and following signs still remains the most common mechanism for providing and receiving wayfinding information in such spaces. This puts individuals who are blind or visually impaired (BVI) at a great disadvantage. This work designs, implements, and evaluates a wayfinding system and smartphone application called CityGuide that can be used by BVI individuals to navigate their surroundings beyond what is possible with just a GPS-based system. CityGuide enables an individual to query and get turn-by-turn shortest route directions from an indoor location to an outdoor location. CityGuide leverages recently developed indoor wayfinding solutions in conjunction with GPS signals to provide a seamless indoor-outdoor navigation and wayfinding system that guides a BVI individual to their desired destination through the shortest route. Evaluations of CityGuide with BVI human subjects navigating between an indoor starting point to an outdoor destination within an unfamiliar university campus scenario showed it to be effective in reducing end-to-end navigation times and distances of almost all participants.
