Under computer control haptic interfaces can create the tactile and kinesthesic sensations. One application is to allow operators to touch virtual objects, for example, icons of graphical displays. An experiment has been designed at the Canadian Astronaut Program to evaluate a haptic device (see ``A Two DOF Planar Haptic Interface: The Pantograph'') in microgravity and compare it to a conventional trackball device. Microgravity flight experiments are planned for the summer 1995.
