Clickers for tactile feedback in the video switch

| tags: ideas, enabling technology

I was talking with Steve Lee about the lack of tactile feedback in our simple video switch. We could play an audio click or even vibrate something like one of the haptic mice that were popular a few years ago. For many users making the switch target tactually interesting will be important.


An inexpensive tactile Braille display and keyboard with reciprocity

| tags: blind, enabling technology, ideas, literacy

I describe an idea for a simple and inexpensive tactile display and keyboard for Braille. The key simplification enabling this design is displaying Braille on six finger tips instead of as six tiny dots under one finger tip. The display is arranged in the same format as standard Braille embossers so users read and write in a reciprocal fashion. The display and keyboard might be useful for teaching Braille to blind children, as a communication system for deaf-blind people, and as a reading aid for blinded adults whose fingers are not sufficiently sensitive to read traditional Braille.
