DualPanto is a non-visual gaming interface for the blind
October 22nd, 2018—
While there are tools that allow the visually impaired to interact with computers, conveying spacial relationships, such as those needed for gaming, is certainly a challenge. To address this, researchers have come up with DualPanto.
As the name implies, the system uses two pantographs for location IO, and on the end of each is a handle that rotates to indicate direction. One pantograph acts as an output to indicate where the object is located, while the other acts as a player’s input interface. One device is positioned above the other, so the relative position of each in a plane can be gleaned.
The game’s software runs on a MacBook Pro, and an Arduino Due is used to interface the physical hardware with this setup.
DualPanto is a haptic device that enables blind users to track moving objects while acting in a virtual world.
The device features two handles. Users interact with DualPanto by actively moving the ‘me’ handle with one hand and passively holding on to the ‘it’ handle with the other. DualPanto applications generally use the me handle to represent the user’s avatar in the virtual world and the it handle to represent some other moving entity, such as the opponent in a soccer game.
