M.I.D.A.S. touch.

This paper describes the development of a working prototype of a novel free-space haptic human-computer interface called MIDAS Touch. MIDAS Touch works by applying physical forces to a user's finger through the production of a dynamic magnetic field. The magnetic field strength is adjusted in real-time based on the user's movement of his/her finger. A user's hand/finger motion in the real world is mapped to movement of a virtual finger in a virtual world through the use of a Leap Motion 3D tracking sensor. As a person's virtual finger collides with objects in the virtual world, the magnetic field strength is varied. In this demo, we present a case of MIDAS Touch coupled to a standard PC as a computer drawing viewer and drawing application for helping individuals with visual impairment feel what they or others have drawn.
