ABSTRACT
Neonode has patented and commercialized the zforce(an abbreviation for “zero force necessary”)touch technology ,which was designed to overcome many of the limitations of today’s touch screens .Thepremise of the company’s approach entails the projection of an infrared grid across an electronic display. Asusers tap, swipe, or write on the screen, zforce detects the location of the touch based on the Interruption ininfrared light projecting across the screen, which translates to coordinates on the grid. The zforcearchitecture and input method is believed to be unique to Neonode. A zforce Touch Screen can be activated ymultiple modes of input, including bare fingers, gloves, styluses, and (multiple simultaneous to touches). It isuncommon today to find both pens.as well as recognizes multi-touch these features innately built into thesame touchscreen. The resistive touch technology used on most PDAs to recognize stylus writing works as aspot on the screen is pressed inward, causing one layer of the touchscreen to make contact with a layerbeneath. This contact sends a signal to the device to recognize the touch. Although relatively low cost,resistive touchscreens do not typically allow multi-touch (swiping, gesturing).
