When a signal inputted to a pixel is erased by setting potentials of a gate terminal and a source terminal of a driving transistor to be equal, a current slightly flows through the driving transistor in some cases, which leads to occur a display defect. The invention provides a display device which improves the yield while suppressing the increase in manufacturing cost. When a potential of a scan line for erasure is raised, a potential of the gate terminal of the driving transistor is raised accordingly. For example, the scan line and the gate terminal of the driving transistor are connected through a rectifying element.

Methods and apparatuses for operating a portable device based on an accelerometer are described. According to one embodiment of the invention, an accelerometer attached to a portable device detects a movement of the portable device. In response, a machine executable code is executed within the portable device to perform one or more predetermined user configurable operations. Other methods and apparatuses are also described.

A touch screen computer executes an application. A method of operating the touch screen computer in response to a user is provided. A virtual input device is provided on the touch screen. The virtual input device comprises a plurality of virtual keys. It is detected that a user has touched the touch screen to nominally activate at least one virtual key, and a behavior of the user with respect to touch is determined. The determined behavior is processed and a predetermined characteristic is associated with the nominally-activated at least one virtual key. A reaction to the nominal activation is determined based at least in part on a result of processing the determined behavior.

A method and system that provides filtered data from a data system. In one embodiment the system includes an API (application programming interface) and associated software modules to enable third party applications to access an enterprise data system. Administrators are enabled to select specific user interface (UI) objects, such as screens, views, applets, columns and fields to voice or pass-through enable via a GUI that presents a tree depicting a hierarchy of the UI objects within a user interface of an application. An XSLT style sheet is then automatically generated to filter out data pertaining to UI objects that were not voice or pass-through enabled. In response to a request for data, unfiltered data are retrieved from the data system and a specified style sheet is applied to the unfiltered data to return filtered data pertaining to only those fields and columns that are voice or pass-through enabled.

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.

A near-to-eye display system for forming an image as an illuminated region on a retina of at least one eye of a user is disclosed. The system includes a source of modulated light, a proximal optic positionable adjacent an eye of the user to receive the modulated light. The proximal optic has a plurality of groups of optically redirecting regions. The optically redirecting regions are configured to direct a plurality of beams of the modulated light into a pupil of the eye to form a contiguous illuminated portion of the retina of the eye. A first group of the optically redirecting regions is configured to receive modulated light from the source and redirect beams of the modulated light into the pupil of the eye for illumination of a first portion of the retina. A second group of the optically redirecting regions is configured to receive modulated light from the source and redirect beams of the modulated light into the pupil of the eye for illumination of a second portion of the retina.

Mobile devices are described, along with related services, systems, and methods. These devices include displays with pixel dimensions and pixel densities in ranges that are chosen to allow users to enjoy a more intuitive and more “desktop-like” Web or multi-media experience compared to other devices, while still enabling the devices to be pocketsize. Also described are devices with touch sensitive areas on the edges or back that let users efficiently and intuitively control some behaviors of the devices by touching the touch sensitive areas in certain ways. Embodiments of the present invention reduces the need for mechanical controls, which enables keeping the frame around the device's display unusually narrow, thereby permitting larger displays without increasing the overall sizes of the devices.

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.

A system for communicating between members of a group is disclosed which includes a communications interface transmitting at least one of voice, video and text communications from an originating member to at least one destination member within a virtual group. The graphical communication flow module graphically depicts to each member of the virtual group the originator and target of different types of communication (text, voice or iconic) occurring simultaneously within the virtual group. The simultaneous access window allows virtual group members to engage in “real-life” group activities (like viewing a video, reviewing a document, or participating in training exercises) while at the same time transmitting, receiving, and viewing communications occurring between computer users connected to the virtual group. This system of providing group interaction over networks has unique and important applications to virtual group counseling, virtual office meetings, and group communications in the form of chat rooms over the Internet.

Head-mounted display systems and methods of operation that allow users to couple and decouple a portable electronic device such as a handheld portable electronic device with a separate head-mounted device (e.g., temporarily integrates the separate devices into a single unit) are disclosed. The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted device and the portable electronic device.

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.

An electronic device has a display and has a touch sensitive bezel surrounding the display. Areas on the bezel are designated for controls used to operate the electronic device. Visual guides corresponding to the controls are displayed on the display adjacent the areas of the bezel designated for the controls. Touch data is generated by the bezel when a user touches an area of the bezel. The device determines which of the controls has been selected based on which designated area is associated with the touch data from the bezel. The device then initiates the determined control. The device can have a sensor for determining the orientation of the device. Based on the orientation, the device can alter the areas designated on the bezel for the controls and can alter the location of the visual guides for the display so that they match the altered areas on the bezel.

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.

A multi-touch system is disclosed that compares finger arrangements at the beginning of multi-touch gestures and discriminates between neutral- and spread-hand performances. Gestures by the neutral- and spread-hand versions of each chord are then mapped to separate, but intuitively related cursor functions or sets of commands. Less-frequently performed functions and commands are typically assigned to the spread-hand chord, since spreading the hand from neutral takes deliberate effort. With these neutral and spread distinctions, a two-handed gesture set can be packed into a one-handed touch surface, or for two-handed touch surfaces, twice as many intuitively customizable gesture command sets can be accomodated.

A transparent, capacitive sensing system particularly well suited for input to electronic devices is described. The sensing system can be used to emulate physical buttons or slider switches that are either displayed on an active display device or printed on an underlying surface. The capacitive sensor can further be used as an input device for a graphical user interface, especially if overlaid on top of an active display device like an LCD screen to sense finger position (X/Y position) and contact area (Z) over the display. In addition, the sensor can be made with flexible material for touch sensing on a three-dimensional surface. Because the sensor is substantially transparent, the underlying surface can be viewed through the sensor. This allows the underlying area to be used for alternative applications that may not necessarily be related to the sensing system. Examples include advertising, an additional user interface display, or apparatus such as a camera or a biometric security device.

A tablet device with a flexible cover is disclosed. Thin flexible display technology can be integrated into the flexible cover without affecting the overall form factor of the cover or tablet device. Adding the integrated display to the flexible cover greatly enhances the overall functionality of the tablet device.
