 Images of mediVR KAGURA-guided rehabilitation. (A) A physical therapist demonstrates VR-guided training tasks. The patient is instructed to catch red or blue falling objects or to touch red or blue fixed targets with their right or left hand controllers, respectively, in a three-dimensional virtual space. These tasks can be provided in the style of a videogame such as (B) a falling carrot thrown by a farmer or (C) a fixed small box bearing a symbol (similar to a police badge) that is used in a popular Japanese television period drama.
