Provided is an optical sensing member, comprising a light guide plate 102 which propagates light from a light source unit 108, detecting units 104, 106 which detect scattered light from the light guide plate 102 being touched, an optical member which guides the scattered light to the detecting units, and a primary control unit 118 which computes the touch location upon the light guide plate 102 on the basis of information relating to the detected light. The optical member has arc-shaped curved surfaces formed on the end parts which face each of the detecting units. Each of the detecting units outputs, as the information relating to the light which is detected by the detecting units, location information corresponding to the angle of entry to the detecting units of the light which is radiated from the facing arc-shaped curved surfaces. It is thus possible to clarify contours of the light which is detected by the detecting units, and to improve the precision of the detection of the touch location.

An active-matrix touchscreen includes a substrate, a system controller, and a plurality of spatially separated independent touch elements disposed on the substrate. Each touch element includes a touch sensor and a touch controller circuit that provides one or more sensor-control signals to the touch sensor and receives a sense signal responsive to the sensor-control signals from the touch sensor. Each touch sensor operates independently of any other touch sensor.

An apparatus and method are described herein, which simultaneously promotes a positive computing experience for users of portable computer systems and increases overall durability and longevity thereof. In one embodiment, an optical apparatus enhances the user computing experience, in one embodiment by simplifying operation, and is much more durable and long-lasting than mechanical switch and dial type devices it may replace. In one embodiment, the present invention is directed to an apparatus, which enables efficient portable computer device function, field, and data selection, gaming, input, interconnection, and other switching-related functions, simplifying operation and enhancing versatility thereof, yet without exposing the portable computer interior to any degree to incursion of environmental contamination. In one embodiment, an optical apparatus obviates openings in a portable computer package which would otherwise be required. In one embodiment, the apparatus, capable of sensing manipulation and directed by software, has a light source and corresponding light sensor.

A method of imitating a texture on a touch surface, the method including the steps of sensing a position of a user's finger on the touch surface, modulating a coefficient of friction of the touch surface in response to the sensed position of a user's appendage relative to the touch surface and/or a derivative thereof, where the friction modulator does not alter the contour of the touch surface in a manner that is perceptible to a user's sight or touch.

The present invention relates to a method, which is operated by a control unit, and which enables the user to select any of the menu elements and switchover between menus at the main display menu of the machines desired to be interacted, or within an application installed on such device. By virtue of said method, the menu elements can be present on the display according to the level cluster of a cone-shaped function with any set of parameters, but also the positioning of the menu elements can also be performed according to the position of the pointer (M) after interacting with the machine. Upon interaction with the machine the corresponding menu element/elements is/are magnified according to the position of the pointer (M). The size of the elements deviated from due to movement of the pointer is reduced, while the elements converged to are magnified. Moreover, the position of the elements can be altered in the movement direction or a certain direction depending on the reverse direction according to the position of the pointer (M).

An operation method of an electronic device for sensing an optical signal is provided. The electronic device includes a plurality of optical sensors and a plurality of light-emitting elements disposed adjacent to the plurality of optical sensors.
