摘要： An apparatus for detecting a pointer within a region of interest comprises a first reflective element extending along a first side of the region of interest and reflecting light towards the region of interest. The first reflective element comprises at least two generally parallel bands thereon, the bands at least comprising a retro-reflective band and a reflective band. A second reflective element extends along a second side of the region of interest and reflects light towards the region of interest, the second side being joined to the first side to define a first corner. The second reflecting element comprises at least two generally parallel bands thereon, the bands at least comprising a retro-reflective band and a reflective band. At least one imaging device captures images of the region of interest including reflections from the reflective and retro-reflective bands of the first and second reflective elements. At least one illumination source is positioned adjacent to the at least one imaging device and directs light across the region of interest towards the first and second reflective elements.

摘要： An apparatus for detecting a pointer includes a waveguide and a touch surface over the waveguide on which pointer contacts are to be made. At least one reflecting device extends along a first side of the waveguide and touch surface. The reflecting device defines an optical path between the interior of the waveguide and the region of interest above the touch surface. At least one imaging device looks across the touch surface and into the waveguide. The imaging device captures images of the region of interest and within the waveguide including reflections from the reflecting device.
