Adaptive projected information handling system output devices
First Claim
1. An information handling system comprising:
- a housing;
processing components disposed in the housing and operable to cooperate to process information;
a projector interfaced with the processing components and operable to present the information as images at a projection surface, the projector generating light for the images with a point light source operable to scan the projection surface;
an input sensor operable to detect objects proximate the projection surface; and
a scan module stored in non-transitory memory and interfaced with the projector, the scan module operable to adjust the light source scan in response to one or more predetermined conditions so that the light source scan traces less than all of the projection surface.

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.

9. A method for adaptive projected output devices, the method comprising:
-
projecting an image at a projection surface with a point light source that scans area to create the image; detecting a predetermined condition associated with the projection surface; and in response to the predetermined condition, automatically altering the scan of the point light source at the projection surface; wherein; detecting a predetermined condition comprises detecting an object disposed in a first portion of the projection surface; and automatically altering the scan of the point light source at the projection surface further comprises adjusting the point light source scan out of the first portion to project the image in a second portion of the projection surface. - View Dependent Claims (10)

11. A method for adaptive projected output devices, the method comprising:
-
projecting an image at a projection surface with a point light source that scans area to create the image; detecting a predetermined condition associated with the projection surface; and in response to the predetermined condition, automatically altering the scan of the point light source at the projection surface; wherein; detecting a predetermined condition comprises detecting that the projected image has a content portion and a non-content portion; and automatically altering the scan of the point light source at the projection surface further comprises adjusting the point light source scan to trace substantially only the content portion. - View Dependent Claims (12)
