An optical touch device and a touch detecting method using the same are provided. The optical touch device is suitable for use with a touch surface and includes a control unit and first to fourth optical capturing units. The first to fourth optical capturing units are disposed on a side of the optical touch device close to the touch surface. The first to fourth optical capturing units are respectively disposed at predetermined distances from the touch surface and are disposed based on predetermined angles. A touch covering area of each of the first to fourth optical capturing units is obtained respectively based on the predetermined distance and the predetermined angle. The touch covering area is positively correlated to the predetermined distance. At least one touch point on the touch surface is calculated by the control unit based on optical sensing information captured by the first to fourth optical capturing units.

Invention principally regards a remotely controllable touch-sensing apparatus. The apparatus comprises a planar light guide, a plurality of light emitters arranged to emit light into the light guide for propagation by total internal reflection inside the light guide, and a plurality of light detectors, each being arranged to detect at least a portion of the emitted light propagating inside the light guide and at least a portion of the ambient light, said detectors being distributed along the periphery of the touch surface such that the optical plane of detection of light coincides with the plane of the light guide, at least one of said detectors being adapted to detect light emitted by an external device configured to emit light. The apparatus also comprises a processor unit configured to, ultimately, generate a digital signal containing data regarding light generated by the external device. Invention also regards a method for enabling control of a touch-sensing apparatus by an external device.

A system is provided that modifies a haptic effect experienced at a user input element, where the user input element is positioned within the housing so that a first contact with the housing defines a first maximum range of a first movement of the user input element. The system receives a position of a user input element of a peripheral device. The system further sends a haptic effect definition to the haptic output device in response to the received position of the user input element. The system further causes the haptic output device to output a force to the user input element of the peripheral device in response to the haptic effect definition. The system further causes the haptic diminishment prevention to define a first diminishment range of the first movement of the user input element, where the first diminishment range is less than the first maximum range and prevents the first contact with the housing.

A novel data processor which can display a plurality of images arranged in a predetermined order, a novel method for displaying data, or a novel program is provided. The data processor includes an input/output unit which supplies operation instructions, an arithmetic unit which determines data marked as a starting point according to the operation instructions to generate image data, and a display portion which displays the image data.
