3632 results about "Touchpad" patented technology

A touchpad or trackpad is a pointing device featuring a tactile sensor, a specialized surface that can translate the motion and position of a user's fingers to a relative position on the operating system that is made output to the screen. Touchpads are a common feature of laptop computers as opposed to using a mouse on a desktop, and are also used as a substitute for a mouse where desk space is scarce. Because they vary in size, they can also be found on personal digital assistants (PDAs) and some portable media players. Wireless touchpads are also available as detached accessories.

Method for presentation of revisions of an electronic document

A method and apparatus for displaying the evolution of an electronic document (e.g. word-processing document, portable-document-format file, spreadsheet, drawing, and the like), containing tracked changes, is disclosed. In accordance with the disclosed method and apparatus, the revisions of an electronic document may be treated as parent frames. In between the parent frames, child frames may be constructed from the combined images of their parent frames. To form a child frame, an image of a parent frame has a degree of translucency as it is combined with the translucent image of the other parent frame, such that every child frame contains traces of the images of both its parent frames. An input device (e.g. keyboard, mouse, touchpad, stylus, voice activation, and the like) may be used to control the frame visible to the user at any one time. The user may use the input device to traverse the frames at various speeds and in either direction, creating the visual illusion that a certain revision of the document is being morphed into its future revisions—or stripped off its changes as it is morphed into previous revisions—depending on the direction chosen by the user.

Touch Sensing Using Shadow and Reflective Modes

A touch panel is described which uses at least one infrared source and an array of infrared sensors to detect objects which are in contact with, or close to, the touchable surface of the panel. The panel may be operated in both reflective and shadow modes, in arbirary per-pixel combinations which change over time. For example, if the level of ambient infrared is detected and if that level exceeds a threshold, shadow mode is used for detection of touch events over some or all of the display. If the threshold is not exceeded, reflective mode is used to detect touch events. The touch panel includes an infrared source and an array of infrared sensors.

Sensors, algorithms and applications for a high dimensional touchpad

A high dimensional touchpad (HDTP) controls a variety of computer windows systems and applications by detecting a user's finger movement in the left-right, forward-backward, roll, pitch, yaw, and downward pressure directions. Measurements obtained from the touchpad of at least two attributes of finger movement at two different time intervals are used to provide a first and a second finger position attribute used to control an application on an electronic device. The finger roll angle is determined by detecting the edge and the peak region of a finger contact area. Also, a visual color displayed in an application operating on an electronic device is controlled by a measured-angle value of a finger in contact with a touchpad.

Touch Screen Element

A capacitive two-dimensional (2D) touch panel has three sets of interleaved electrodes. A first set of electrodes is spaced apart along the y-direction and these are galvanically connected to each other by a resistive strip connected at either end to a connection line. A second set of electrodes is also arrayed along the y-direction and these are galvanically connected to each other via a notionally non-resistive first connection. A third set of electrodes is also arrayed along the y-direction and these are galvanically connected to each other via a notionally non-resistive second connection. The second and third sets of electrodes are interleaved without galvanic cross-conduction to provide a gradient along the x-direction to resolve touch position in the x-direction. The first set of electrodes resolves touch position along the y-direction. Passive or active capacitive sensing techniques may be used to acquire the position information from the 2D touch panel.

Apparatus and method for manipulating a touch-sensitive display panel

The present invention enables to easily perform a graphic processing even when a touch panel is used. When a resistance film unit is pressed with a pen or a finger, output voltages associated with the X coordinate and the Y coordinate position are changed and these output voltages are transmitted as the X coordinate data and the Y coordinate data to a touch panel driver. According to the output from the resistance film unit, the touch panel driver generates an event for supply to a GUI handler. The touch panel driver includes a two-point specification detector which detects two point specifications and causes to calculate coordinates of the two points. The GUI handler generates a message corresponding to the GUI according to the event and supplies the message to an application. The GUI handler includes a processing mode modification block which differently interprets the event when a single point is specified and when two points are specified, thereby modifying the graphic processing mode.
