Imaging of the turn space and path of movement of a wheelchair for remodeling houses of individuals with SCI

The houses of individuals with SCI (spinal cord injury) are remodeled according to their wheelchair operation ability, the method of body transfer, and their use of welfare equipment before they return from the hospital. In our rehabilitation center, house remodeling is demonstrated for individuals and family members using three-dimensional computer graphic images before the house construction is started. In this study, the turning radius is calculated using image sequences of the wheelchair that are estimated using the speeds of the motion of both the wheelchair rear wheels as measured using rotary encoders. The two-dimensional remodeled house image on which the turn space of the wheelchair is displayed is created using the individual's calculated turn radius of the wheelchair. Moreover, to design the toilet room, the path of motion and the image sequences of the wheelchair approaching and leaving the toilet are displayed on an image of the toilet room.
