Abstract: An apparatus for detecting a pointer within a region of interest includes a first reflective element extending along a first side of the region of interest and reflecting light towards the region of interest. 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 is joined to the first side to define a first corner. A non-reflective region generally in the plane of at least one of the first and second reflective elements is adjacent the first corner. At least one imaging device captures images of the region of interest including reflections from the first and second reflective elements.

Abstract: A touch system comprises a large scale touch surface on which an image is presented and at least two imaging devices looking across the touch surface and having overlapping fields of view. Processing structure communicates with the imaging devices and processes image data acquired by the imaging devices to determine pointer contacts on the touch surface using triangulation. The processing structure further executes at least one application to facilitate user interaction with the touch surface. Methods of interacting with the touch surface are also disclosed

Abstract: 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.
