ABSTRACT
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.

AudioDraw: user preferences in non-visual diagram drawing for touchscreens
W4A '16: Proceedings of the 13th International Web for All ConferenceIt can be very difficult and sometimes impossible for people who are blind to create visual diagrams on their own. Even with sighted assistance, it can be difficult to verbally convey the visual image in one's mind. We conducted a survey to determine ...
Investigating Cursor-based Interactions to Support Non-Visual Exploration in the Real World
ASSETS '18: Proceedings of the 20th International ACM SIGACCESS Conference on Computers and AccessibilityThe human visual system processes complex scenes to focus attention on relevant items. However, blind people cannot visually skim for an area of interest. Instead, they use a combination of contextual information, knowledge of the spatial layout of ...
Feasibility of using haptic directions through maps with a tablet and smart watch for people who are blind and visually impaired
MobileHCI '16: Proceedings of the 18th International Conference on Human-Computer Interaction with Mobile Devices and ServicesIn order to navigate through the world, people who are blind and visually impaired typically use maps through either textual directions or tactile printouts. However, visual maps on a touchscreen are not accessible to this population. Two prototypes ...
