Toshiba introduces its new multi-touch technology on resistive touchscreens
Primarily made for the industrial and medical application, Toshiba new Multi-touch technology works, unlike other on regular resistive touchscreens, yep the very same kind of touchscreens that were used on the first PDAs. By bringing multi-touch technology on such resistive screen it will now be possible for your to get the same benefit of a capacitive touchscreen while using a pen/stylus or even gloves while touching the screen.
Consumers are becoming increasingly used to touchscreens in personal devices such as mobile phones and tablet PCs. These products utilise multi-point (generally two-point) sensing to deliver flexibility and control in on-screen operations. Similar capabilities are valuable in industrial and medical equipment where the ability to manipulate, for example, a slider and rotary switches simultaneously provides a greater degree of control.
Smartphones generally employ capacitive touchscreens that can recognise dual-touch gestures, such as pinch/zoom, but are unable to function with a pen, stylus or gloved hand. Resistive touchscreens, conversely, can accept pen, stylus and gloved inputs but do not typically support multi-touch. Resistive touchscreens cost significantly less than their capacitive equivalents, a factor that is particularly significant if touch technology is to migrate from its current bastion in high value portable consumer devices to the more cost-sensitive industrial marketplace.
Toshiba’s demonstration shows a resistive touchscreen that, as well as accepting the usual pen, stylus and gloved inputs, can also interpret multi-touch gestures. The Resistive Touch Technology Demonstrator comprises an ARM9 development board front end for the touchpad and display coupled with an add-on PCB that amplifies the touch stimulus and calculates position and movement.
The demonstrator is intended to showcase the capabilities of technology currently under development within Toshiba and planned for introduction later in the year.
