Various types of ink corresponding to non-overlapping wavelength domains in absorbing lights are utilized on a pattern displaying medium for marking coordinate dots and data dots of a plurality of data blocks. While a scanning device is utilized for scanning the pattern-displaying medium, the marked coordinate dots and data dots are precisely recognized and read. While the pattern displaying medium is to be marked, the coordinate dots are marked in advance, and then the data dots are marked according to the marked coordinate dots for preventing positioning errors. Besides, at least one locality dot is used in each data block. While the scanning device is utilized for scanning the pattern displaying medium, a reading direction of each data block is indicated by the at least one locality dot so as to precisely read dots of each data block.

Data encryption method implemented on a pattern displaying medium with at least two types of ink

An optical operating apparatus includes a soft plate, a transparent supporting plate, a deformable unit, a light source, and an image sensing module. The soft plate is configured for being pressed. The transparent supporting plate is disposed under the soft plate. The deformable unit is disposed between the transparent supporting plate and the soft plate, and has a pattern configuration. The deformable unit deforms as applying an external force on the soft plate and restores after the external force is removed. The light source is configured for providing a light beam to the transparent supporting plate and the deformable unit, and the light beam is reflected by the deformable unit. The image sensing module is arranged on a transmitting path of the light beam reflected by the deformable unit, and a visual field of the image sensing module covers the whole deformable unit. In addition, the present invention also relates to a method for determining operation motion.

Optical touch control apparatus and method thereof

An optical operating apparatus includes a display panel, a transparent supporting plate, a deformable unit, a light source, an image sensing module, a function selecting module and a processing module. The deformable unit is disposed between the transparent supporting plate and the display panel. The deformable unit has a pattern configuration. The deformable unit deforms as applying an external force on the display panel and restores after the external force is removed. The light source provides a light beam to the deformable unit, and a visual field of the image sensing module covers the whole deformable unit. The function selecting module is disposed beside the display panel and has a plurality of function selecting buttons for selecting a predetermined function. The processing module is electrically connected with the display panel, the function selecting module, the image sensing module and the light source. The processing module is configured to control the display panel to display a predetermined picture according to a corresponding predetermined function.
