Dr. Miller’s research activities center around the application of robot systems and control to improve mobility and/or the human experience of controlling mobile devices. In particular: 1. Smart mobility assistance: Intelligent scooters and wheelchairs. Wheelchairs and similar devices that are situationally aware and can assist the user not only in basic mobility, but also in the control of mobility to help achieve common tasks involving positioning, obstacle avoidance, navigation and control of peripheral devices. 2. Mobility training and amplification: Assistive devices to assist in the user development and acquisition of mobility skills and the cognitive skills related to mobility. 3. Interacting with mobile devices through visual, tactile and haptic interfaces such that control feels natural and has improved performance over more traditional vehicle control interfaces.
