DualPanto: A Haptic Device that Enables Blind Users to Continuously Interact with Virtual Worlds
summary
A handheld dual-pantograph system maps an avatar to a me handle and actuates an it handle to continually show a moving object’s position; hardware uses aluminum linkages, Teflon washers, low‑ratio rotation motors and PID position/rotation control, with a teardrop handle shape for orientation. Six visually impaired participants play a soccer prototype after 8–15 minutes training, report high enjoyment (6.5/7), can pass, aim and dodge, but the device currently supports only one multiplexed “it” object.
