Development of gait training system using the virtual environment simulator based on bio-information

For hospitalized patients who cannot freely walk outdoors, we have proposed a new gait training system using a virtual environment simulator in which the scene reflected in the HMD (head mounted display) changes with walking. We have studied the association of electrical bio-information with various stresses, and a positive correlation between healing music and stress resolution has been obtained by pulse wave measurements. We developed equipment which measures pulse wave and heart rate and installed it in the virtual environment simulator. Then the conditions of the user were obtained while undergoing gait training, and the bio-information was feed back to control the gait training system.
