    摘要: A method and apparatus are provided for detecting activation of a touch panel. The method includes the steps of providing an N by M touch panel including a matrix of N rows of touch elements along a first axis and M columns of touch elements along a second axis, providing N optical beams where a characteristic of each beam of the N beams is different than the corresponding characteristic of any other of the N optical beams, where the summation of a characteristic any first group of the N optical beams is different than the summation the corresponding characteristic of any other N beams and where each respective beam of the N optical beams corresponds to an input of each of the N rows; and summing the characteristic from an output of each of the N rows.

    摘要: A method and apparatus are provided for detecting activation of a touch panel (16). The method includes the steps of providing an N by M touch panel (16) including a matrix of N rows of touch elements (22, 26) along a first axis and M columns of touch elements (22, 28) along a second axis, providing N optical beams (60, 62) where a characteristic of each beam of the N beams is different than the corresponding characteristic of any other of the N optical beams, where the summation of a characteristic any first group of the N optical beams (60, 62) is different than the summation the corresponding characteristic of any other N beams (60, 62) and where each respective beam of the N optical beams corresponds to an input of each of the N rows; and summing the characteristic from an output of each of the N rows. The method further includes the steps of providing M optical beams (60, 62) where a characteristic of each beam of the M beam (60, 62) is different than the corresponding characteristic of any other of the M optical beams, where the summation of a characteristic of any first group of the M optical beams is different than the summation the corresponding characteristic of any other M beams and where each respective beam of the M optical beams corresponds to an input of each of the M columns, summing the characteristic from an output of each of the M columns and unambiguously identifying a touch element or multi-touch elements (22, 26, 28) of the N rows and M columns of touch elements based upon the summation of the outputs.
