Touch-screen image scrolling system and method

Electronic image displays, of lists that extend beyond the vertical display dimension of the display screen, are displaced in the vertical direction by touching the screen with a finger and then moving the finger in the desired direction on the screen. In a natural manner, the initial speed of displacement of the displayed image corresponds to the speed of motion of the finger along the screen. When the user's finger is disengaged from the screen, the system senses the disengagement and thereafter allows the vertical displacement speed of the image to decrease at a controlled rate. When it is desired to stop the motion of the image at a given point, or to make a selection from the displayed image, the system measures the length of time that the finger is in contact with the screen and the distance that the finger is moved during that time, to determine if a selection is desired or if it is desired only to stop displacement of the image. That is, a short term contact with the screen, say 500 ms or less, accompanied by little or no displacement on the screen, can be identified as an intended selection, while a longer contact with little or no accompanying displacement can be interpreted as being intended to stop the motion of the image without making a selection.

Cellular phone with special sensor functions

Specific ambient and user behaviour sensing systems and methods are presented to improve friendliness and usability of electronic handheld devices, in particular cellular phones, PDAs, multimedia players and similar.
The improvements and special functions include following components:
    • a. The keypad is locked/unlocked (disabled/enabled) and/or the display activated based on the device inclination relative to its longitudinal and/or lateral axes.
    • b. The keypad is locked if objects are detected above the display (for example the boundary of a bag or pursue).
    • c. The keypad is locked/unlocked (disabled/enabled) and/or the display activated based on electric field displacement or bio-field sensing systems recognizing the user hand in any position behind the handheld device.
    • d. The electric response signal generated by an electric field through the user hand in contact with a receiver plate is used to identify the user and in negative case lock the device.
    • e. Connection with incoming calls is automatically opened as soon as a hand is detected behind the device and the device is put close to the ear (proximity sensor).
    • f. The profile (ring-tone mode, volume and silent mode) can be changed just putting the device in a specific verse (upside up or upside down).
    • g. Has a lateral curved touchpad with tactile markings over more surfaces to control a mouse pointer/cursor or selection with the thumb finger.

Real-time receipt, decompression and play of compressed streaming video/hypervideo; with thumbnail display of past scenes and with replay, hyperlinking and/or recording permissively intiated retrospectively

Streaming compressed digital hypervideo received upon a digital communications network is decoded (decompressed) and played in a client-computer-based "video on web VCR" software system. Scene changes, if not previously marked upstream, are automatically detected, and typically twenty-one past scenes are displayed as thumbnail images. Hyperlinks within the main video scene, and/or any thumbnail image, show as hotspots, with text annotations typically appearing upon a cursor "mouse over". All hyperlinks-as are provided and inserted by, inter alia, the upstream network service provider (the "ISP")-may be, and preferably are, full-custom dynamically-resolved to each subscriber/user/viewer ("SUV") upon volitional "click throughs" by the SUV, including retrospectively on past hypervideo scenes as appear within the thumbnail images. Hyperlinking permits (i) retrieving information and commercials, including streaming video/hypervideo, from any of local storage, a network (or Internet) service provider ("ISP"), a network content provider, and/or an advertiser network site, (ii) entering a contest of skill or a lottery of chance, (iii) gambling, (iv) buying (and less often, selling), (v) responding to a survey, and expressing an opinion, and/or (vi) sounding an alert.

Method and apparatus for integrating manual input

Apparatus and methods are disclosed for simultaneously tracking multiple finger and palm contacts as hands approach, touch, and slide across a proximity-sensing. compliant, and flexible multi-touch surface. The surface consists of compressible cushion, dielectric, electrode, and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize signal-to-noise ratio and to reduce wiring complexity. Such distributed transduction circuitry is economical for large surfaces when implemented with thin-film transistor techniques. Scanning and signal offset removal on an electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contact and extracts shape, position and surface proximity features for each group. Groups in successive images which correspond to the same hand contact are linked by a persistent path tracker which also detects individual contact touchdown and liftoff. Combinatorial optimization modules associate each contact's path with a particular fingertip, thumb, or palm of either hand on the basis of biomechanical constraints and contact features. Classification of intuitive hand configurations and motions enables unprecedented integration of typing, resting, pointing, scrolling, 3D manipulation, and handwriting into a versatile, ergonomic computer input device.
