smartwheels | mapping for accessibility
DESCRIPTION
Everyday, wheelchair users navigating across city streets, campuses, and pathways face obstacles due to inaccessible routes and changing terrain. Now, with SmartWheels, they can rely on real-time, personalized route directions. The power of the SmartWheels system is that the wheelchair itself becomes an internet-connected sensor suite for the user. The wheelchair utilizes terrain-sensing technology, which determines the type of surface underneath the wheels as well as grade, elevation, and surrounding curbs and obstacles. Users can enter additional information about the environment to provide context to the collected data. SmartWheels is an integrated system comprised of a SmartWheels Sensor Kit, smartphone app, and crowd-sourced accessible maps for any browser. The Connector Kit can be installed on any wheelchair and provides Internet and sensor capabilities directly to the wheelchair. After installing the Connector Kit, the person can track his or her route data, plus get or give recommendations for improved routes. SmartWheels is a brain collective of Human Centered Design & Engineering (HCDE) students at the University of Washington and we seek to solve real-life accessibility problems. Luke Easterwood, Susan Oldham, Annuska Perkins and Tristan Plank designed SmartWheels as part of an Interaction Design class taught by Kelly Franznick of Blink Interaction at UW.TRANSCRIPT
