INTRODUCTION
Neonode has patented and commercialized the zForce touch technology, which was designed to overcome many of the limitations of today’s touchscreens. The premise of the Company’s approach entails the projection of an infrared grid across an electronic display. As users tap, swipe, or write on the screen, zForce® detects the location of the touch based on the interruption in infrared light projecting across the screen, which translates to coordinates on the grid. The zForce® architecture and input method is believed to be unique to Neonode.
A zForce Touch Screen can be activated by multiple modes of input, including bare fingers, gloves, styluses, and (multiple simultaneous touches). It is uncommon today to find both of pens, as well as recognizes multi-touch these features innately built into the same touchscreen. The resistive touch technology used on most PDAs to recognize stylus writing works as a spot on the screen is pressed inward, causing one layer of the touchscreen to make contact with a layer beneath. 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).
TOUCH SCREEN
A Touch screen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or hand. Touchscreens can also sense other passive objects, such as a stylus. Touchscreens are common in devices such as game consoles, all-in-one computers, tablet computers, and smart phones.
MULTI TOUCH
In computing, multi-touch refers to a touch sensing surface's (trackpad or touchscreen) ability to recognize the presence of two or more points of contact with the surface. This plural-point awareness is often used to implement advanced functionality such as pinch to zoom or activating predefined programs. Multi-touch was invented in 1982 at the University of Toronto
CONCLUSION
Neonode’s optical infrared touch technology can be integrated into consumer and industrial electronics to enable touch controls. The Company seeks to compete with low-cost resistive touch options while outperforming today’s advanced capacitive touch solutions. To do so, Neonode strives to effectively combine the advantages of each technology into one streamlined solution.
