English: Touchscreen

It would also be particularly useful for handwriting recognition

Touchscreens found in most mobile devices today use capacitance or resistance technology – fine for detecting input from a finger, but not so great when it comes to detecting how much pressure that finger is applying. However, this limitation could be about to change with news that Japanese touch screen manufacturer, Nissha, has licensed new technology that allows a touchscreen to detect pressure, even from a finger. This adds a third dimension to touchscreen interaction and opens up a raft of potential applications.

The licensing agreement concerns Peratech’s Quantum Tunnelling Composites (QTC) technology, which is used to create ultra-thin, low power force sensitive switches of any shape or size. Adding force sensitivity to touchscreens offers the prospect of adding the third dimension to touchscreen interfaces and could give users the ability to search deeper into a file structure simply by pressing harder, or control an avatar’s movement through a game more naturally. It would also be particularly useful for handwriting recognition in Asian markets due to the variation in line thickness in Asian scripts.

  1. Hi my name is Andrew Buddingh I am a student that is wondering if it possible to make a pressure sencetive vest that can register impacts of 6mm to 12mm all across the chest about 12" inch by 12" inch. with out registering impacts of just bumps into things. The objects that will be forced toward the vest will be shoot from a cannon that reaches a volicty of 120 fps to 400 fps. If it is possible could you please write me a letter or email me.
