Is gestural technology getting easier?
Gestural interfaces, once requiring such complex, cumbersome technology that real-world installations were rare, appear to be getting slicker and simpler to manage.
At Digital Signage Expo in Las Vegas this week, 3M Touch Systems was showing off gesture-recognition functionality for its Dispersive Signal Technology touchscreen system, in particular the MicroTouch System DST2270DX display.
It supports such functions as expanding, zooming in on, and rotating objects via hand movements, as well as navigational gestures like flicking and scrolling.
At CeBIT in Hannover next week, however, Germany’s Heinrich-Hertz-Institut (HHI) – part of the Fraunhofer-Gesellschaft research organisation – will go a step further by demonstrating gestural control of a glasses-free 3D display without gloves or markers.
The system, called iPoint 3D, is a further development of the technology used in HHI’s iPoint Explorer gesture-based travel-information unit (pictured).
“The heart of iPoint 3D is a recognition device, not much larger than a keyboard, that can be suspended from the ceiling above the user or integrated in a coffee table,” said HHI researcher Paul Chojecki. “Its two built-in cameras detect hands and fingers in real time and transmit the information to a computer.”
The same technology could be used to control appliances, HHI suggests.
