    摘要: An optical touch device includes an indication plane, two image sensing units and a processing unit. The two image sensing units are disposed at two corners of the indication plane diagonal to each other, respectively, and the two corners define a diagonal line connected therebetween. The processing unit is electrically connected to the two image sensing units. When two touch points are performed on the indication plane, the processing unit determines whether the two touch points are located at opposite sides of the diagonal line, respectively, according to images sensed by the two image sensing units. Once the two touch points are located at opposite sides of the diagonal line, respectively, the processing unit calculates and outputs coordinates of the two touch points immediately according to the images sensed by the two image sensing units.

    摘要: A frameless optical touch device includes an indication plane, an image sensing unit, a light emitting unit and a processing unit. There is no any frame disposed on a periphery of the indication plane such that a first light from an external environment can enter a sensing region defined on the indication plane through the periphery of the indication plane. The light emitting unit emits a second light to the sensing region. When there is no any touch object in the sensing region, the image sensing unit senses the first and second lights to generate a first image. When a touch object is in the sensing region, the image sensing unit senses the first and second lights to generate a second image. The processing unit compares brightness of the first image with brightness of the second image so as to obtain a position blocked by the touch object.

    摘要: A system for generating calibration information for an optical imaging touch display device includes a calibration tool and a processor. The calibration tool is disposed within an image capturing range of an image capturing unit, and has a surface with mark patterns. Each adjacent pair of the mark patterns defines a pattern boundary. The calibration tool is disposed such that the pattern boundary forms a predefined positional relationship with a corresponding predefined location on the optical imaging touch display device. The processor receives an image frame corresponding to an image of the surface of the calibration tool, performs edge detection on the image frame to determine a position of each of at least one detected pattern edge, and generates the calibration information with reference to the position thus determined and the corresponding predefined location.
