As i have selected zforce touch screen technology as the topic for the academical technical seminar...i need some references of the ieee paper based on zforce touch screen technology.

ZForce's touch technology is the company's innovative 2D optical touch technology. It offers a number of important advantages compared to traditional touch technologies, such as capacitive or resistive. With zForce technology, you can use any type of screen or screen. In fact, zForce technology works with any surface - flat, round or any other shape. Another advantage is that any type of object can be used - a finger or a stylus, a car key, nails, gloves and common feathers.
Neonode has patented and commercialized zForce® (an abbreviation of "zero force required") touch technology, designed to overcome many of the limitations of today's touchscreens.
The premise of the company's approach involves the projection of an infrared grid through an electronic display. When users touch, slide or write on the screen, zForce® detects the location of the touch based on the interruption of infrared light projected through the screen, which translates into coordinates in the grid. It is believed that the zForce® architecture and input method are unique to Neonode.
A zForce touch screen can be activated by multiple input modes, including bare fingers, gloves, highlighters and (multiple simultaneous taps). It is rare nowadays to find both of the pens as well as recognizes multi-touch these features innately built on the same touch screen. The resistive touch technology used in most PDAs to recognize pen writing functions as a point on the screen that is pressed inward, causing a layer of the touch screen to make contact with a layer underneath. This contact sends a signal to the device to recognize the touch. Although relatively low cost, resistive touch screens usually do not allow multi-touch (swiping, gestures).
