Tech promises cheap, force-sensitive multi-touch

Touchco's IFSR multi-touch due in 2010

Young startup Touchco revealed today that it has developed a new touchscreen technology that could add pressure sensitivity to multi-touch even as it drives the cost down. Known as Interpolating Force-Sensitive Resistance (IFSR), it uses embedded resistors that alter the level of capacitance, or stored electric charge, depending on the amount of pressure applied at a given point. The technique would still allow for the light, quick touches of a capacitive touchscreen like the iPhone's but could add extra functions for more deliberate presses.
