Solar System Sonification: Exploring Earth and its Neighbors Through Sound

2017-06 , Tomlinson, Brianna J. , Winters, R. Michael , Latina, Christopher , Bhat, Smruthi , Rane, Milap , Walker, Bruce N.

Informal learning environments (ILEs) like museums incorporate multi-modal displays into their exhibits as a way to engage a wider group of visitors, often relying on tactile, audio, and visual means to accomplish this. Planetariums, however, represent one type of ILE where a single, highly visual presentation modality is used to entertain, inform, and engage a large group of users in a passive viewing experience. Recently, auditory displays have been used as a supplement or even an alternative to visual presentation of astronomy concepts, though there has been little evaluation of those displays. Here, we designed an auditory model of the solar system and created a planetarium show, which was later presented at a local science center. Attendees evaluated the performance on helpfulness, interest, pleasantness, understandability, and relatability of the sounds mappings. Overall, attendees rated the solar system and planetary details very highly, in addition to providing open-ended responses about their entire experience.

What's the Weather: Making Weather Data Accessible for Visually Impaired Students

2016 , Tomlinson, Brianna J. , Bruce, Carrie M. , Schuett, Jonathan H. , Walker, Bruce N.

We determined during a collaboration project in Kenya that students with visual impairments were interested in learning about weather data as part of their Science, Technology, Engineering, and Mathematics (STEM) education. Unfortunately much of this data is not accessible to the students due to lack of integration with assistive technologies, as well as limited access to landline internet. Therefore we created the Accessible Weather App to run on Android and integrate with the TalkBack accessibility feature that is already available on the operating system. This paper discusses the process for determining what features the users’ would require, and our methodology for evaluating the beta version of the app. User feedback was positive and suggestions have helped advance the interface design. The overall goal of our project is to develop, evaluate, and integrate the Accessible Weather App into weather and meteorology learning activities for students with visual impairments.
