Abstract
As survival rate of cerebrovascular disease due to improvements in medical care, the number of patients requiring such rehabilitation is growing. Since the effects of rehabilitation show only if it is continuous, it is hard to keep motivation in monotonous rehabilitation environments. Therefore, with the use of latest virtual reality devices, it is possible to a rehabilitation environments like taking a walk outside while being at the rehabilitation's facilities. This research is about a gait rehabilitation system with the use of a Head-Mounted-Display (from now on, HMD). This HMD uses a smart phone and a method for changing the field of view on the HMD when gait is detected by the smartphone sensors. As a result, it was possible to walk with a virtual environment displayed in the HMD. However, this HMD had low frame rate issues. Future work will improve frame rate and compare with high-performance HMDs such as the OculusRift.
