Interactive tactile display for computer screen

This invention creates a display you can touch, converting a visual image from a screen into a pattern of raised pins. It works by sensing the light directly from the screen, without using lenses, and then adjusts the height of tiny pins to match the image, with darker areas making the pins taller. A specific version can also recognize words on the screen and show them in Braille.

Why it matters: The core challenge of word recognition and Braille translation, a significant software hurdle in 2001, is now much more tractable with modern AI and OCR. Additionally, MEMS technology and high-resolution, low-cost imaging sensors have matured, making the physical display more feasible.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedDense micro-actuator array, control electronics, software.
