摘要:
Motion detection notification is described. In an embodiment, a motion detector in a portable device detects a motion of the device and issues an activation signal when the detected motion has a magnitude greater than a preset threshold. A detection notification component in the portable device then receives the activation signal and initiates communication with an additional device that detects a corresponding motion to the motion of the portable device and is configured for communication with the portable device.

摘要:
A device for detecting the position of a human finger or other object on a touch-sensitive scrolling pad. Dual independent oscillators may be used to generate two pulse trains at frequencies dependent upon the capacitance of two conductors resulting from the position of the finger on the conductors. The pulses from each oscillator may be counted over a time interval. A ratio-metric measurement may be taken by calculating the ratio of the two counts, and a sum may also be calculated. The ratio of the two counts relates to finger position on the device, and their sum relates to finger pressure upon the device.

A scrolling device for a computer may include a touch-sensitive surface, which may be elongated and/or have one or more active regions. Scrolling may be performed in manual as well as automated ways that may result in more accurate and efficient scrolling. Scrolling, as displayed on the screen, may further be rounded to the nearest document text line and/or distance unit, even though a more precise scrolling location value may be stored and/or tracked.

A method and computer input device are provided for controlling a displayed object. Using the method and computer input device, an indication of the amount of rotation and translation of the computer input device is received. A decision is then made as to whether to use the amount of rotation of the computer input device to control a displayed object based on the amount of translation of the computer input device.
摘要:
In an input device, a camera captures images of a surface. Using the images, the input device determines its orientation. Data representing the orientation of the input device and data representing the captured image are communicated from the input device to a host computing device.
摘要:
A computer input device includes a camera for capturing an image of a pattern on a surface. A processor in the computer input device determines equations for lines from the image of the pattern, applies the line equations to a transform to form transformed line equations, and uses the transformed line equations to determine the height of the computer input device above the surface.
摘要:
A computer input device and computer system are provided that determine a height of the computer input device over a surface. Based on the height, an audio signal generator generates an audio driver signal. The audio driver signal is applied to an audio signal generate that generates an audio signal based on the audio driver signal.
