  This is the preprint version of our paper on 2015 International Conference on
Virtual Rehabilitation (ICVR2015). In this paper, we described the imagination
scenarios of a touch-less interaction technology for hemiplegia, which can
support either hand or foot interaction with the smartphone or head mounted
device (HMD). The computer vision interaction technology is implemented in our
previous work, which provides a core support for gesture interaction by
accurately detecting and tracking the hand or foot gesture. The patients
interact with the application using hand/foot gesture motion in the camera
view.
