  • Patent number: 9430865
    Abstract: Disclosed herein is a real-time dynamic non-planar projection apparatus and method, which can reduce visual errors, such as distortion of a screen image or deviation from a border area, upon projecting screen images from a projector onto the surface of a non-planar object that is moved in real time. The presented real-time dynamic non-planar projection apparatus includes a preprocessing unit for preprocessing data related to a static part of a screen image to be projected onto a non-planar surface. A real-time projection unit classifies non-planar objects in the screen image to be projected onto the non-planar surface into a rigid body and a non-rigid body using data output from the preprocessing unit, respectively renders the rigid body and the non-rigid body depending on a viewer's current viewpoint, and projects rendered results onto the non-planar surface via projection mapping.

  • Patent number: 9398144
    Abstract: A mobile device operates in a standard mode of operation, or operates in a visually impaired (VI) mode of operation designed for visually impaired users and in which a display screen of the mobile device is turned off by default. The display screen may thus remain turned off in the VI mode even when conditions under which the display screen is turned on in the standard mode are satisfied. The display screen may further remain turned off in the VI mode even when conditions under which a touch-screen input interface of the mobile device is turned on in either of the standard and VI modes. The mobile device may be configured to automatically transition from the VI mode to the standard mode in response to detecting a gaze directed towards the display screen.

    Abstract: A communication system, method and communication terminal are configured to permit bandwidth reduction when communication partners are engaged in a communication session. In one embodiment, a communication terminal such as a cellular phone or tablet may turn off at least one of its display and camera sensor within a predetermined amount of time when the terminal is detected as being positioned near a user's ear via at least one sensor of the terminal. In some embodiments, the communication terminal may also transmit one or more messages to communication devices of communication partners engaged in the communication session to inform those devices that video transmissions should no longer be sent to the communication terminal. The communication terminal and other communication devices involved in the communication session may also stop transmitting video as a result of the detection of the communication terminal being positioned near a user's ear.
