Publication number: 20100229090Abstract: Embodiments include position detection systems that can identify two touch locations mapped to positions proximate a GUI object, such as a boundary. In response to movement of one or both of the two touch locations, the GUI object can be affected, such as moving the boundary to resize a corresponding object and/or to relocate the boundary, or the GUI object can be selected without movement of the touch locations. Embodiments include single touch gestures, such as identifying a rolling, bending, or other movement occurring while a touch location remains substantially the same and interpreting the movement as an input command. Embodiments may utilize one or more optical sensors having sufficient sensitivity to recognize changes in detected light due to variations in object orientation, makeup or posture caused by the rolling, bending, and/or other movement(s).Type: ApplicationFiled: March 4, 2010Publication date: September 9, 2010Applicant: Next Holdings LimitedInventors: John David Newton, Keith John Colson

Publication number: 20100045629Abstract: An optical touch detection system may rely on triangulating points in a touch area based on the direction of shadows cast by an object interrupting light in the touch area. When two interruptions occur simultaneously, ghost points and true touch points triangulated from the shadows can be distinguished from one another without resort to additional light detectors. In some embodiments, a distance from a touch point to a single light detector can be determined or estimated based on a change in the length of a shadow detected by a light detector when multiple light sources are used. Based on the distance, the true touch points can be identified by comparing the distance as determined from shadow extension to a distance calculated from the triangulated location of the touch points.Type: ApplicationFiled: November 6, 2009Publication date: February 25, 2010Applicant: Next Holdings LimitedInventor: John David Newton
