Three animals and one habitat environment, such as farm field, forest, and pond, are displayed on the top side and
the bottom side, respectively. In this course unit, the participants should imitate the ‘grasp’ action
(open and then close the hand), select one of the animal icons, and move the animal to
its corresponding habitat environment. Meanwhile, with the TI system, participants perform the clickand-
drag task and move the desired animal icons to the corresponding habitat
environment
