Touch screens that track two fingers will soon seem basic. At least if you compare them with the multitouch-sensor ClearPad 3000 Series, recently announced by Santa Clara, Calif.-based Synaptics.
The transparent sensor tracks up to 10 simultaneous finger touches--we assume that should cover most uses--making possible complex multifinger gestures such as closing an application by "crumpling" it with several fingers, or playing polyphonic sounds on a virtual piano keyboard.
Apple made multitouch popular with its iPhone, which debuted about four months after Synaptics introduced its currently shipping two-finger sensor,. Though widely speculated that Apple is using Synaptics' technology, that has not been confirmed.
One phone thatis the T-mobile G1 by HTC, and manufacturers such as Samsung and LG are also confirmed customers.
The new sensor features an accuracy of plus/minus 1 mm, is 0.3 mm thick, and is available in sizes up to 8 inches diagonally.
That supported screen size, and the speculated relationship between Synaptics and Apple, makes us wonder if this sensor is what Apple's been waiting for to launch its.
Synaptics is also introducing a more basic model, the ClearPad 1000 Series, that supports single-finger gestures such as tapping, pinching, pressing, and flicking. These sensors are available in sizes up to 4.3 inches diagonally.
The company says manufacturers already have the sensors in hand, and consumers can expect to products containing them by the end of the year.
The sensors use capacitive technology, usually considered to be more sensible to fingers than resistive sensors, and also more transparent. Capacitive sensors cannot be used with a stylus or a glove though, as opposed to resistive sensors.
