NVIDIA DirectTouch on Tegra 3 gets partners
NVIDIA just ahead of Mobile World Congress on Saturday lined up partners for its unique DirectTouch (PDF interface technology. Atmel, Cypress, N-Trig, and Synaptics will have touchscreen controllers that can use NVIDIA's quad-core Tegra 3 to handle some of the touch input processing instead of just their own circuitry. The method not only improves the responsiveness dramatically but could lower power use by keeping just one chip active.
Adding DirectTouch should help companies making primarily Android- and Windows 8-based tablets, and Android-based smartphones, get to shops faster than they would otherwise, even as it speeds up touch response.
The newcomers didn't say which phone and tablet makers they were involved with, but ASUS, HTC, Fujitsu, LG, and others either have been or are known to be working on Tegra 3 mobile devices, many of which should be on shelves by the spring.
