  11. 11. Next Window: Human Touch <ul><li>Operating Systems: </li></ul><ul><li>Windows XP, Windows 2000, Mac OS and Linux. </li></ul><ul><li>Calibration : </li></ul><ul><li>Four-point calibration required when the touch screen is powered up for the first time. </li></ul><ul><li>Mouse Functionality </li></ul><ul><li>Full mouse functionality: click, drag, double-click and right-click. Double-click and right-click timers can be controlled independently from the operating system. </li></ul><ul><li>Applications Software </li></ul><ul><li>Point anywhere </li></ul><ul><li>Operates drawing, spreadsheet, presentation programs </li></ul><ul><li>Draw, write, move/edit objects and scroll through menus </li></ul><ul><li>Spin and rotate objects with your fingers or hand </li></ul>
  12. 12. NextWindow's Optical Touch Screen Technology: How does it work? <ul><ul><li>“ NextWindow's optical touch screen technology uses two line scanning cameras located at the corners of the screen. The cameras track the movement of any object close to the surface by detecting the interruption of an infra-red light source. The light is emitted in a plane across the surface of the screen and can be either active (infra-red LED) or passive (special reflective surfaces).” </li></ul></ul><ul><li>NextWindow 2403 Camera Bloc k </li></ul><ul><li> </li></ul><ul><ul><li>A circuit board called the the Digital Signal Processor (DSP) receives signals from the cameras and runs software that compensates for optical distortions. It triangulates the position of the finger (or any object) extremely accurately. </li></ul></ul><ul><li>Surface </li></ul><ul><li>NextWindow's glass touch surface overlays the display surface. </li></ul><ul><li>System uses optical technology, no special surface coatings are required. </li></ul><ul><li>Clear image with a clear glass touch surface </li></ul><ul><li>Touch registers just before the finger or object actually touches the surface. </li></ul><ul><li>http://www.nextwindow.com/ </li></ul>
  13. 13. <ul><li>A Range of Possibilities : </li></ul><ul><li>1900 Miniature Touch Frame </li></ul><ul><ul><li>uses low profile cameras mounted on the surface of the glass. </li></ul></ul><ul><li>1803 Through Glass </li></ul><ul><ul><li>locates the cameras behind glass for security purposes. </li></ul></ul><ul><li>2800 Rugged Touch Frame </li></ul><ul><ul><li>uses precision alloy camera blocks rigidly mounted in a steel frame. </li></ul></ul><ul><li>All models: </li></ul><ul><ul><li>infrared light source and scanning cameras are synchronized with an algorithm, that eliminates ambient light effects. </li></ul></ul><ul><li>NextWindow's Two Main Categories: </li></ul><ul><li>Touch panel overlays for existing LCD or plasma screens. </li></ul><ul><li>Interactive touch frames for integration into manufacturers' display models. </li></ul>
  14. 15. Design I
  15. 16. Design II
  16. 17. Issues I <ul><li>The Xbox 360 is not ready for interactive displays just yet, but the XNA Framework has been used in the design of the Wiimote API </li></ul><ul><li>The current version of the XNA Framework does not have any classes to do interactive displays yet </li></ul><ul><li>Columbia University has come out with an API (GoblinXNA) to do pervasive computing with the XNA Framework </li></ul>
  17. 18. Issues II <ul><li>Many of the touch tables we looked at in our research were high-level prototypes </li></ul><ul><li>The places that will create these tables for you often constrain you to their specifications and software packages </li></ul>
  18. 19. What We Learned <ul><li>Touch table technology is still relatively new </li></ul><ul><li>It is important to paper prototype any table-based interface </li></ul><ul><li>For interactive table top games, game design principles must be “tweaked” to fit these new interfaces </li></ul><ul><li>The tables produced by the major electronics manufacturers are not out on the market yet, they are prototypes </li></ul>
