Abstract: A matrix switching type pressure-sensitive touch detecting device has a simple configuration. The matrix switching type pressure-sensitive touch detecting device may include an upper substrate, a lower substrate, and a unified sensor module disposed between the upper substrate and the lower substrate.

Abstract: A method of detecting a click event for sensing a motion of a finger corresponding to a click on a sensing area of an optical pointing device, the method including: obtaining an image of the finger from the sensing area; sensing a change in the image of the finger; analyzing a horizontal movement of the finger based on the change in the image of the finger; and generating a click signal when the horizontal movement of the finger is within a predetermined range is provided.

Abstract: By a control method of a screen of a terminal apparatus with a pointing device according to an embodiment of the present invention, a pressing operation of a user's finger for selecting a predetermined function displayed on a screen is sensed. At this time, it is determined whether the pressing operation is temporary or is continued for a predetermined time. When the pressing operation is temporary, the pressing operation is determined as an easy click operation, such that a function linked to a region where a cursor or a pointer is positioned is implemented on the screen. Further, when the pressing operation is continued for the predetermined time, the previously set control function is implemented on the screen by determining the pressing operation as the easy press operation.

Abstract: The present invention relates to an ultra thin optical pointing device, and a personal portable device having the optical pointing device. The optical pointing device includes a PCB (508). An infrared LED (501) is provided on a side of the top surface of the PCB. A cover plate (503) detects motion of a finger, which is a subject. An illumination system (502) transmits light from the infrared LED to the cover plate. An image forming system lens (505) is placed below the cover plate to condense reflected light. An optical image sensor (507) receives a reflected image of the subject and detects motion of the subject. A body tube (509) is provided on a side portion over the PCB. The illumination system, the cover plate and the image forming system lens are made of an optical plastic material capable of passing only a wavelength band of infrared rays.

Abstract: The present invention relates to an optical pointing device for mobile terminals, which can improve assembly efficiency and stability. An optical pointing device according to the present invention includes a holder having an accommodation opening therein. Light emitting means is installed in the accommodation opening of the holder. A condensing element includes a pair of prisms installed in the accommodation opening of the holder and integrated into a single structure so as to condense light emitted from the light emitting means, and a condensing lens disposed between the paired prisms. An image sensor captures light provided through the condensing element and calculates the captured light as displacement values. The condensing element includes a lens holder coupled to the condensing lens so as to maintain stable installation of the condensing lens between the paired prisms.
