Abstract

Projected input and output devices adapt to a desktop environment by sensing objects at the desktop environment and altering projected light in response to the sensed objects. For instance, projection of input and output devices is altered to limit illumination against and end user'"'"'s hands or other objects disposed at a projection surface. End user hand positions and motions are detected to provide gesture support for adapting a projection work space, and configurations of projected devices are stored so that an end user can rapidly recreate a projected desktop. A projector scan adjusts to limit traces across inactive portions of the display surface and to increase traces at predetermined areas, such as video windows.

Claims

1. A method for interactive support at an information handling system, the method comprising:

detecting a predetermined condition at the information handling system; and

projecting one or more images proximate a housing of the information handling system in response to the detecting, the one or images depicting plural of assignable features for interactions with a physical totem;

presenting a password interface with the second MEMS device; and

accepting a password input at the password interface to authorize access to a resource associated with the first image.

3. The method of claim 1 wherein the second image comprises configuration settings for end user interaction with a keyboard.

4. The method of claim 1 further comprising:

detecting a predetermined object with an input sensor; and

in response to the detecting, adjusting the projecting of the first and second images.
