Laser pointers and a touch screen: intuitive interfaces for autonomous mobile manipulation for the motor impaired
"Based on interviews of patients with amyotrophic lateral sclerosis (ALS), we have developed and tested three distinct interfaces that enable a user to provide a 3D location to El-E ("Ellie" a prototype assistive robot) and thereby select an object to be manipulated: an ear-mounted laser pointer, a hand-held laser pointer, and a touch screen interface. We present the results from a user study comparing these three user interfaces with a total of 134 trials involving eight patients with varying levels of impairment recruited from the Emory ALS Clinic. During this study, participants used the three interfaces to select everyday objects to be approached, grasped, and lifted off of the ground...Results indicate that robots can enhance accessibility by supporting multiple interfaces."
RouteCheckr: personalized multicriteria routing for mobility impaired pedestrians
"We developed RouteCheckr, a client/server system for collaborative multimodal annotation of geographical data and personalized routing of mobility impaired pedestrians. The construction of algorithms supporting multiple bipolar criteria is described, applied to route calculation, and demonstrated in our university's campus. To satisfy individual requirements, user profiles are incorporated enabling adaptivity over heterogeneous user groups while preserving privacy. Finally, a general architecture for RouteCheckr is presented and simulation results are analyzed."
