  • Interactive input system
    Patent number: 8692768
    Abstract: A method for resolving ambiguities between at least two pointers in a plurality of input regions defining an input area of an interactive input system. The method includes capturing images of the plurality of input regions, the images captured by a plurality of imaging devices having a field of view of at least a portion of the input area, processing image data from the images to identify a plurality of targets for the at least two pointers within the input area, and analyzing the plurality of targets to resolve a real location associated with each pointer.
    Type: Grant

    Date of Patent: April 8, 2014
    Assignee: SMART Technologies ULC
    Inventors: Alex Chtchetinine, David E. Holmgren, Brinda Kabada, Grant McGibney, Daniel McReynolds, Yun Zhang, Ye Zhou
  • INTERACTIVE INPUT SYSTEM AND METHOD
    Publication number: 20120007804
    Abstract: A method of resolving ambiguities between at least two pointers within a region of interest comprises capturing images of the region of interest and at least one reflection thereof from different vantages using a plurality of imaging devices, processing image data to identify a plurality of targets for the at least two pointers, for each image, determining a state for each target and assigning a weight to the image data based on the state, and calculating a pointer location for each of the at least two pointers based on the weighted image data.
