Abstract
Crutches are often used in rehabilitation by injured patients. However, patients are not usually familiar with how to use crutches properly. Improper usage can cause the patients to fall, potentially leading to further injury. In order to ensure patients' safety, a training environment for crutch walk training with a LCD projector was developed. In this training environment, proper landing position was estimated from the motion of a crutch, and it was instructed on the walk way by a LCD projector that is hung from the ceiling. The effectiveness of landing position instruction with a LCD projector was confirmed through experiment.
