We present our participatively and iteratively designed 3D audio-tactile globe that enables blind and low-vision users to perceive geo-spatial information. Blind and low-vision users rely on learning aids such as 2D-tactile graphics, braille maps and 3D models to learn about geography. We employed participatory design as an approach to prototyping and evaluating four different iterations of a cross-sensory globe that uses 3D detachable continents to provide geo-spatial haptic information in combination with audio labels. Informed by our participatory design and evaluation, we discuss cross-sensory educational aids as an alternative to visually-oriented globes. Our findings reveal affordances of 3D-tactile models for conveying concrete features of the Earth (such as varying elevations of landforms) and audio labels for conveying abstract categories about the Earth (such as continent names). We highlight the advantages of longitudinal participatory design that includes the lived experiences and DIY innovations of blind and low-vision users and makers.

About the competition
The Innovative Designs for Accessibility (IDeA) student competition aims to inspire students to use their creativity to develop innovative, cost-effective and practical solutions to accessibility-related issues resulting in communities that are more accessible for persons with disabilities.
The objectives of the program are:
to contribute to the creation of a culture of accessibility in Canada
to motivate students to think about accessibility issues and to include accessibility in their creation of social and technological innovations now and in the future
to develop cost-effective, practical and innovative concepts, programs, initiatives or designs that address everyday accessibility issues
Who is eligible?
