MULTITOUCH TECHNOLOGY: TRULY NECESSARY?

摘要

Your decision on whether to select projected capacitance-touchscreen technology, specifically the mutual capacitance variant of it, hinges in part on whether your application requires the ability to simultaneously decode the location and movement direction and rate of two or more touch inputs. You might believe, for example, that the zoom, sweep, and rotate capabilities of modern high-end cell phones and track pads indicate that they implement multitouch support.
