Multitouch was actually invented by companies other than Apple, but it never became as popular. Microsoft’s Surface, LG Prada were one fo the first devices with multitouch.
Synaptics, Atmel,N-trig, Raydium, Cypress and Focaltech all big names in the field of touch-based devices are joining hands to start using the world’s most powerful Mulittouch technology — NVIDIA’s DirectTouch platform.
Nvidia’s DirectTouch is ultra responsive especially in multitouch scenarios where user is using multiple fingers in a touch interaction. Basically, DirectTouch offloads some of the work needed to track and process finger input from the controller to the Tegra 3. Tegra 3 handles this at the wire speed, thereby improving response and battery life.
It was first introduced in CES 2012, but failed to grab attention with no partners. Now that all industry leaders are up for it, future for this technology sure seems bright. We can assume that all the future Tegra 3 tablets would come with DirectTouch platform.
Here’s a video demo of this breathtaking Touch platform:
“The additional processing power provided by Tegra 3 allows device manufacturers to offer enhanced pen and multi-touch performance without increasing cost or power consumption.”
DirectTouch improves touch responsiveness by offloading a portion of the touch panel processing to the CPU cores in the NVIDIA® Tegra® 3 processor, the world’s only 4-PLUS-1™ quad-core processor with a fifth battery saver core. The architecture also simplifies the implementation of touch-based hardware and user interfaces, requiring less power while delivering more scalable performance.DuoSense supports all Windows, Android-based tablets and convertibles, and will be compatible with the Windows 8 operating system.
