Assistive Product Touchscreen mit haptischem Feedback durch Wärme

Researchers at Texas AandM have integrated into the displays a way to make short-term changes in temperature on the surface in a small space. This stimulates nerve cells in the skin in the same way as sensing structures. In this way, corresponding shapes can be simulated and virtual buttons can be felt.

In the future, notebooks will also tend to be offered with virtual keyboards on a second touchscreen. With the tactile keys, it would then also be possible to achieve similar typing speeds as is the case with a physical keyboard.

To achieve such a haptic, the temperature change does not have to be particularly strong.

The heat method is much more reliable compared to ultrasound and offers less wear potential than real deformations.
