Photographs of actual training using the objects in mixed reality (MR)-board training. The photographs show actual training using objects. Visual feedback was provided to the patients through a monitor that reflected the position of the object on the board. (A) “Matching the same shape” involved positioning of six objects correctly while comparing those displayed on the monitor. (B) “Moving the object” involved moving specific objects to the right and left repetitively. (C) “Stacking the objects” involved stacking objects on top of one another, without them collapsing, according to the shape shown on the monitor.
