Modifying screen resolution as a factor of user distance

Screen resolutions are increasing and improving user experience of gaming, movies, sport events, etc. However, this is at the cost of power consumption and network usage (for streaming data).

    However, the increased resolution is not always noticeable to the naked eye depending on the size of the display and the distance the user is from the display. http://en.wikipedia.org/wiki/Optimum_HDTV_viewing_distance#Human_visual_syste m_limitation http://www.engadget.com/2006/12/09/1080p-charted-viewing-distance-to-screen-siz e/

    And take for instance the 4K (Ultra HD) technology which requires ~20Mbps speeds to stream content - this is far beyond the reach of most households currently.

    The system herein relies on tracking user distance from a display - this can be achieved in a number of ways:
1. Calculating distance using existing tracking software and the computer webcam or game console linked camera
2. Signal generator on the user and triangulation - i.e. in glasses / phone / remote (this could be signal strength calculations: http://www.cs.rug.nl/√£iellom/tesi/takens.pdf, RFID: http://www.rfidjournal.com/articles/view?7393, or even possibly Bluetooth calibrated to the environment)

3. It can even be a couple of preset locations that can be identified by user and triggered by placing remote on a pad, sensor in the seat etc.

    If multiple users are detected (i.e. user camera tracking / facial recognition technologies) the distance to the closest user is used for input to the model.

    When the user moves or the display is powered on, the distance the user...
