Interactive Braille module

Laptop for blind people: A new display surface makes graphics accessible for blind computer users.

Working together with metec and IMS Chips from Stuttgart within the framework of the HyperBraille project supported by the Federal Ministry for Economic Affairs and Energy, Hahn-Schickard, for the first time, has created the basis for blind people and those with visual impairments to access image information alongside textual information. This device allows much more comprehensive access to multimedia, so the visually impaired can now also access the Internet through a Braille surface display. Thanks to this display, blind users can, for the first time, navigate and use graphical user interfaces on computers and conventional user programs. Even the "mouse click function" can now be utilized via the touch sensors.

MID technology makes modules possible for an interactive Braille display

The Braille display surface features a total of 7200 Braille pins. The core of the display are the Braille modules, which each contain ten pins with a spacing of 2.5 mm for each. The pins can be pushed out of the surface individually by 0.7mm using vertically mounted piezo actuators. Touch sensors integrated on the surface make it possible for the user to interact by clicking the mouse. The Braille modules are produced in LPKF-LDS® technology, which fulfills high requirements in terms of the 3D conductor guide. Modules of this type can be lined up in two dimensions, compactly and in any way required. The approximately DIN A4 size interactive display consists of a total of 720 individual Braille modules.
