Abstract: An optical touch system comprises a first imaging device configured to be directed toward a side surface of a target on a touch surface and a processing device. The first imaging device sequentially generates a first picture having an image of the target and a second picture having an image of the target. The computing device is configured to calculate a first dimension of the target using the first picture and a second dimension of the target using the second picture, and to determine whether the target is formed by one object or two objects by the first and second dimensions.
