Nvidia CEO demonstrates Tegra 4 stylus input, pressure sensitivity
The CEO of Nvidia used Computex to demonstrate how <a href="http://macnn.com/rd/286938==http://www.electronista.com/articles/13/05/21/software.defined.modem.hits.150mbps.speed.without. hardware.changes/" rel='nofollow'>Tegra 4</a> could be used to improve stylus input on a tablet. Jen-Hsun Huang drew on a Tegra 4 reference tablet with a basic capacitive stylus, and appeared to show the tablet being able to detect some level of pressure sensitivity, without the aid of an active stylus and digitizer. <br />
<br />
During the demonstration of the company's third generation of <a href="http://macnn.com/rd/286939==http://www.electronista.com/articles/12/02/25/nvidia.directtouch.on.tegra.3.gets.partners/" rel='nofollow' target="_self" title="">DirectTouch</a> to <em>The Verge</em>, <a href="http://macnn.com/rd/286940==http://www.theverge.com/2013/6/3/4393556/nvidia-tegra-4-stylus-gpu-processing" rel='nofollow'>Huang</a> claimed the technology is $20 cheaper per unit than an equivalent active stylus setup. "The precision of DirectTouch is many, many times higher than your normal touch controller, the resolution and sample rate are much higher," said Huang. <br />
<br />
Considering the uptake of Tegra 3 and the improved quad-core Tegra 4 in tablets, the cost saving per unit and minimal extra hardware could reach end users in the future, though this could come in the form of cheaper pressure sensitive devices, or alternatively the addition of pressure sensitivity to tablets as standard.
