Mobile devices equipped with touch screens, such as the iPhone, are without a doubt a stellar forward progression in device interface that is very intuitive to users, but still have their faults. The technology behind the screens fault due to occlusion and the way in which the touch is mapped to cursor position making it sometimes difficult to make a selection, especially if you have large fingers. Enter LucidTouch, a technology in the works from Microsoft and Mitsubishi Electric lab research.
LucidTouch employs a pseudo transparency that displays the fingers as shadows from behind the screen but not other objects behind it. The shadow effect is essentially a feature designed to make the user experience more natural than simply displaying touch points coming from the back of the screen which might confuse a user as to which finger is associated with which dot, with the shadow transparency the user needn’t think making the UX more intuitive. A passive touch feature allows the user to utilize their thumbs in making direct touch selections from the front of the device which may be used simultaneously with other fingers at the back using the multi-touch ability of the device.
