“…We measure the rotation degree of the right and left rear wheels using the rotary encoders (E6A2-CW3E, made by OMRON) that are attached to the wheelchair frame so that the wheels of the encoders are kept in complete contact with both rear wheels of the wheelchair using the elastic spring as the axis of rotation [4]. We can also detect the direction of the rotation (clockwise or counter-clockwise) of each rear wheel because the encoder has two output phases.…”

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.

“…We have proposed a system that can show the space in which the patient's wheelchair can be moved or turned on a two-dimensional house image, as shown in figure 2. The turn space of the wheelchair is estimated by comparing the house image and the moving or turn area of each patient's wheelchair, as shown in figure 3 [4] . In this figure, P t (i, j) represents the turn area of the wheelchair.…”

“…In our rehabilitation center, the house remodeling demonstrations are carried out using three-dimensional computer graphics in order to prove to be useful for medical staff when they plan house remodeling for SCI patients [3]. For the demonstration, we proposed the evaluation system that showed the calculated turn and movement space on the two-dimensional remodeled house image [4]. Many kinds of electric wheelchairs have been developed.…”

In remodeling the house of an SCI (Spinal Cord injury) patient, it is necessary to accurately determine and carry out changes that are suitable with regard to the patient's ability. In our rehabilitation center, house remodeling is demonstrated for patients and family members through the use of threedimensional computer graphic images before the remodeling occurs. We have proposed an evaluation system that can show whether there is sufficient space in the remodeled house for a wheelchair to be moved or turned using a computer graphic image. The turn space is calculated using only a wheelchair size. Especially, the wheelchair turning radius determined by the physical limitation of each patient is different among SCI patients. In this study, the turning radius is calculated by measuring the moving speed of right and left wheelchair rear wheel using the rotary encoder in order to estimate the actual turn space of wheelchair for SCI patient's remodeling house.

In our rehabilitation center, house remodeling is demonstrated for patients and family members through the use of three-dimensional computer graphic images before the remodeling occurs. We here propose an evaluation system that can show whether there is sufficient space in the remodeled house for a wheelchair to be moved or turned. That space is calculated using a computer graphic image of the house and the specific wheelchair belonging to the patient. Moreover the evaluation system can measure the movement and turn area of the wheelchair.
