Seeing Images with Touch and Sound
Mar-18-17
A force-feedback joystick that vibrates to simulate textures could help the visually impaired interpret the image on a computer screen.Developed by a team from Purdue University, the assistive technology system requires that the user hold the joystick to move a cursor on the computer screen. As the cursor moves over different images, the joystick will vibrate to simulate different textures in conjunction with the system’s audible cues.

How small differences in temperature visually impaired can feel with their fingers? Could a screen to visually impaired based on different temperatures between colours be possible? That could be also a touchscreen, if there is a separate OK-pick.

Could that be a glove and a camera instead of a joystick? Visually impaired could ‘look’ all surfaces with their hand. Picture could be done also with varying pressures using air or blunt needles.
