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 dual-mode input apparatus is disclosed and includes a panel, a processing module, and an image-capturing system capable of capturing images in front of the panel. The image-capturing system can capture a touch input image and a gesture input device by an image-sensing component and a light-modulating component. The processing module processes the sensed images to determine input information. Alternatively, the image-capturing system can include an image-capturing device capable of rotating relative to the panel. The processing module is therefore capable of controlling rotating of the image-capturing device so as to capture a touch input image and a gesture input image selectively for the processing module to determine input information. Therefore, the dual-mode input apparatus of the invention can provide two input modes by use of the same image device, which overcomes the limitation of a conventional single image-capturing system being applied only to a single input architecture.
