  • Touch system and method for determining pointer contacts on a touch surface
    Patent number: 6947032
    Abstract: A system and method for determining pointer contacts on a touch surface includes a touch surface to be contacted by a pointer. At least one imaging device having a field of view looks generally along the touch surface. At least one processor communicates with the at least one imaging device and analyzes images acquired by the at least one imaging device to detect the relative positions of a pointer and a reflection of the pointer therein and thereby determine if a pointer contact with the touch surface has been made.
    Type: Grant
    Filed: March 11, 2003
    Date of Patent: September 20, 2005
    Assignee: Smart Technologies Inc.
    Inventors: Gerald D. Morrison, Randy McCharles, Scott Yu Tseng Su, Manvinder Singh
  • Passive touch system and method of detecting user input
    Publication number: 20050088424
    Abstract: A passive touch system includes a passive touch surface and at least two cameras associated with the touch surface. The at least two cameras acquire images of the touch surface from different locations and have overlapping fields of view. A processor receives and processes images acquired by the at least two cameras to detect the existence of a pointer therein and to determine the location of the pointer relative to the touch surface. Actual pointer contact with the touch surface and pointer hover above the touch surface can be determined.
