Today at Computex, Nvidia’s CEO Jen-Hsun Huang showed off a software-based pressure sensitive display powered by the company’s Tegra 4 chipset, using a normal non-digitizer stylus to draw on it.
As the Verge reports :
Using the third generation of Nvidia’s own Direct Touch technology on a reference Tegra 4 tablet, Huang was able to draw with extreme precision using a very basic and crude conductive stylus. “The precision of Direct Touch is many, many times higher than your normal touch controller,” said the CEO, “the resolution and sample rate are much higher.”
The software is able to sense how much the stylus’ head is pressing down on the display at the point of writing and adjusts the stroke sizes accordingly. Huang also flipped the stylus around to erase what he wrote, and because the stylus had a specific thickness at that end, it’s able to “know” that it should be erasing.
Also, speaking at Computex, Asia’s biggest PC trade show, Chief Executive Jen-Hsun Huang told The Wall Street Journal that the Santa Clara, Calif., company is interested in technologies that “fit into its businesses,” but declined to give more specifics. He revealed that Nvidia was open to acquisitions.
The chip maker is expanding beyond selling chips by developing a portable device that can play video games. The handheld console called Shield will be priced at $349 and is on track to ship by the end of June, Mr. Huang said.
