  • Patent number: 8502788
    Abstract: A mobile terminal including a body and a display module, which is flexible and is capable of receiving a touch input and a method of controlling the mobile terminal are provided. The method includes setting the touch sensitivity of a display module to a first level; if the display module is bent or folded, setting the touch sensitivity of a bent or folded portion of the display module to a second level; and if the display module is unbent or unfolded and thus returns to its original shape, setting the touch sensitivity of the bent or folded portion of the display module back to the first level. Accordingly, it is possible to adaptively adjust the touch sensitivity of the display module according to whether and how the display module is bent or folded.

  • Patent number: 8427440
    Abstract: Tools and techniques for contact grouping and gesture recognition for surface computing are provided. These tools receive, from a finger grouping subsystem, data representing velocity parameters associated with contact points, with the contact points representing physical actions taken by users in interacting with software applications presented on a surface computing system. These tools also identify gestures corresponding to the physical actions by analyzing the velocity parameters, and provide indications of the identified gestures to the software applications.

  • Patent number: 8405621
    Abstract: In some embodiments, an electronic device with a touch interface detects one or more user gestures that correspond to instructions to vary the playback speed of a media file that is being played on the device. In response, the device initiates a variable rate scan through the media file, forward or backward. The touch interface can be a touch screen or touch pad.

  • Patent number: 8294633
    Abstract: Provided are methods and systems for reducing visual distortion in near-to-eye (“NTE”) visual display systems that is worn, at least partially, on a viewer's head. The movement rate of the viewer's head is sensed while an image that comprises individual content frames is displayed on the NTE using a vertically based raster scan. A characteristic of the raster scan is varied to mitigate distortion of the content frames due to the viewer's head movement.

  • Patent number: 8130199
    Abstract: A keyboard type input device used in conjunction with a wristwatch or a portable telephone has multiple key positions provided as character entry keys. Each key corresponds to one key in the selected row of the conventional QWERTY keyboard. A second set of control buttons provide for the selection of which row of a conventional QWERTY keyboard are represented by the character keys in addition to other functions such as case shift, and alpha-numerical control functions. A selected row is shown on a display, as visual feedback. Alternatively the keys are implemented as LCDs with pressure sensors and the characters of the selected row are displayed directly on the corresponding key positions. The keyboard finds particular use in portable devices as it demands less space than traditional keyboards.
