To present GestureCollection, a set of applications designed to offer cognitive stimuli and motor coordination, through an unconventional way of human-computer interaction. The applications were based on Natural User Interface, Open Natural Interaction and gesture recognition from depth images provided by the Kinect sensor. GestureCollection contains three applications (GesturePuzzle, GestureChess and GestureMaps) that allow gestural interaction with virtual reality environments through movements of upper and lower limbs. This set of applications allows muscle recruitment in different ranges of movement and speed of execution, besides showing potential to reduce the monotony of motor therapy.
