Toshiba Resistive Multi-touch Screen

Toshiba developed a proprietary algorithm for multi-touch resistive touchscreen and they exhibited a demo at Embedded World 2011. The hardware is based around Toshiba TMPA900 (ARM926EJ-S core running at 200 Mhz) and runs embedded Linux.

Resistive display controlled by Toshiba TMPA900 MCUThis type of system is aimed at home appliances (washing machine, refrigerator…), industrial and medical applications and can be used with a pen, stylus or gloved hand. For example, a doctor wearing gloves would be able to use multi-touch gestures on such screens whereas it would not be possible on capacitive touchscreens or standard resistive touchscreens. It was not specified but I suppose that technology would only support 2 points since they only showed two fingers gesture in the demo. This should not be a problem for the type of application. An another advantage of this solutions is that it brings multi-touch technology to cost sensitive industrial applications. The technology is still under development and will be introduced to the market later this year.

You can see a demo of the resistive touchscreen system in the video below (up to 3:20)
