An Interactive Infrared Sensor Based Multi-Touch Panel
      Vasuki Soni, Mordhwaj Patel, Rounak Singh Narde
Abstract: This paper contextualizes an idea of implementing an Interactive touch sensitive user interface. It is an optical touch sensing technique and architecture that allows precision sensing of hands, fingers, and other objects within a constrained 2-dimensional plane. This paper gives the details of the touch panel - a hardware and software based architecture for multi-touch sensing. This is a flat-panel optical multi-touch scheme using a linear array of modulated light receivers which surround the periphery of a display to detect touch. It is a point-to-point visual hull sensing technology, meaning it uses much of modulated infrared sensors and many IR LEDs [4] (940nm) to create a series of invisible light beams that cross the screen. When these beams are being interrupted, it means something has touched the screen, and we can visualize interruption of the beams to reconstruct the visual hull of any objects inside the sensor frame. This way the touch interrupt occurred is first transformed into an image with several scan lines and then many such images make a video clip (which contains the information of the touch point/ Blob) which is theninterfaced with the Image processing software for the Blob detection [15] and Mouse cursor control [17].
