Abstract: The invention relates to a movement assembly (2) particularly, although not necessarily exclusively, for use in the movement of an item in the form of a display screen (20) between a number of possible positions within a predefined environment and/or the possibility of altering the height and/or angle of the display screen at the particular location. The display screen is mounted on a bracket (14) which is moveable and which, in turn, is mounted on a movement assembly including a vehicle (12) for movement along guide means and drive means are provided to allow the movement assembly to be moved in response to remote control signals and/or in a predesignated manner to the required position and provide the display panel at the required orientation.

Abstract: A user control device operates with a variety of host systems, including computers, televisions and recorded or streaming video playback devices, and gaming systems, is mounted to the user's hand. The user control device includes audio and optical sensors for capturing audio and image or video data, allowing the use of voice commands and display focal center alignment control for “swiping” or scrolling the display. A combined inertial (accelerometer(s), gyroscope(s) and a magnetometer) sensor detects translation and rotation movement of the user control device for pointing and selecting within real or virtual three-dimensional space. Haptic (e.g., vibration) feedback units provide tactile feedback to the user to confirm double clicks and similar events.
