PIT---Projected Infrared Touch
PIT is a new type of infrared multi-touch technology with excellent performance and special mechanical/design features to bring IR touch into the future. Industrial designers are no longer limited to Projected Capacitive or Resistive “Touch Windows” to achieve modern design.

AHow It Works
Invisible IR light
The infrared beams generated by emission diodes are reflected through a prism-like light guide and go across the front glass surface. gTouch position calculation is IR type with performance enhancements to meet Windows 8 criteria.

requirements
Only responds to finger or capacitive stylusPrice, reliability & quality challenges in large f ( i l 18 ”)format (typical over 18.5”)High NRE for customized formatEMS challenges when system integrationLong leadtime due to low yield for large formatAnti-vandal options limited

Flat Bezel Areas are Important
Utility and Design
Mobile device leads in design (i e Mobile device leads in design (i.e., iPad) with structural rigidity important
Old Windows UI slowed down touch acceptance by consumer
Now, Windows 8 Touch has defined flat bezel areas as important feature to its bezel areas as important feature to its user experience concept
Android designs also follow “flat bezel Android designs also follow “flat bezel area” trend, of course

PIT’s Environmental Characteristics
Can be sealed to meet IPX1, IP54 & IP64 standards
PIT is well-suited for industrial/rugged environments
Any glass or plastic can be used (subject to meeting surface flatness constraints for low fly height) High ambient-light performance is excellentg g pBut, not for mobile devices: edges are susceptible to drop impact

Summary: GeneralTouch PIT Benefits
Market requires more options than P-Cap and today’s optical/multi-touch IR for new design directions and trends
PIT costs less and is more flexible than typical P-Cap for vertical-market volumesPIT solves the majority of the issues with camera-based optical and traditional infrared touch
PIT also extends what is possible today with P-Cap by adding touch surface material flexibility and active bordersWindows 8 logo test certified, but PIT can also address those who don’t need all of the specifications for a Win8 certified deviceWide size-range with a single technology: 15” up to 84” without any performance variationEasy to integrate, no P-Cap like EMC & grounding issues, and no camera re-calibration issues as in optical imaging
