Nvidia CEO Jen-Hsun Huang has shown an interesting new stylus technology at Computex 2013.
Namely, the Nvidia official has demonstrated how a non-digitizer stylus can be used to perform actions normally only possible with a digitizer one – such as the S Pen used with Samsung Galaxy Note devices and made by Wacom (a company in which Samsung has bought a stake).
Using a Tegra 4-powered 7-inch tablet, Huang has used a normal stylus to draw and write at different levels of thickness, depending on the pressure he was applying, as you can see in the image below. Furthermore, he showed that the bottom of the stylus could even perform as an eraser.
According to Engadget, sensitivity was excellent, giving a lot of hope for the technology’s future.
Nvidia says that the innovation should help save on battery life and also promises to detect curved lines in a better fashion. The technology will only work on Nvidia’s own Tegra 4 hardware, combined with its DirectTouch technology. The latter moves some of the load of processing the touch input from the controller to the processor.
Unfortunately, the company hasn’t mentioned yet when we’ll see the new technology in a commercial product.
