Pointing devices Remote controls QT1101 charge-transfer (‘QT’) QTouchTM IC is a self-contained, patented digital controller capable of detecting near-proximity or touch on up to ten electrodes. It allows electrodes to project independent sense fields through any dielectric such as glass or plastic. This capability coupled with its continuous self-calibration feature can lead to entirely new product concepts, adding high value to product designs. The devices are designed specifically for human interfaces, like control panels, appliances, gami...
