CobU is a talking arithmetic calculator, especially designed to be used by people that are visually impaired or blind.
It provides direct audio and haptic feedback and it features and extra "STATUS" button, which states at any time what actions have been taken so far.
CobU is simple to use: - Click (touch and release) anywhere just to hear what button was pressed. - Keep button pressed to actually select it. - Select CLEAR to reset. - Select DELETE to return to cancel last step.
