Set-up and scenarios. a RGS setup in the hospital showing the transparent acrylic table in front of which the desktop computer with the Kinect (on a tadpole that elevates it above the screen) is placed. In order to use the second Kinect and the overhead projector on the scaffold above the table for the real world evaluation scenario, a white cover can be placed over the acrylic surface. During a training session, the user sits in a chair facing the screen while resting his/her arms on the table. b Spheroids scenario, where sets of colored spheres are launched towards the player who has to intercept them. c Whack-a-mole scenario, where the user freely chooses which limb to use in order to reach towards an appearing mole. d Collector scenario, where a set of patterned spheroids as indicated in the upper-left corner of the screen need to be collected. e Virtual evaluation scenario, an abstract version of the Whack-a-mole scenario, where the patient has to reach towards an appearing cylinder. f Real-world scenario, where the user has to reach towards randomly appearing dots that are projected from above on the table surface in front of him or her
