Disney Research has announced some new touch interface technology that add extra gesture functionality to existing touchscreens and more exotic items like doorknobs and even the water's surface. Touché works by sensing capacitive signals across a range of frequencies -- whereas typical systems only pick up signal at a single frequency. This Swept Frequency Capacitive Sensing (SFCS) can recognize exactly how we interact with an object or surface, not limited to surface area differences. According to Disney Research, this could include embedding different commands for when a user pinches or grasps a hooked-up object. One proof of concept door knob allows it to be locked or display a "be right back" sign depending on exactly how it's handled. Get the full explanation -- and see some watery fingertip detection -- right after the break.
