System and method for adjusting display brightness levels according to user preferences

A method for associating a brightness level and an ambient light level with an identifier for a user currently authorized to access a computer comprising:

• receiving an ambient light level signal indicative of a current ambient light level on a display;
• receiving a brightness level signal indicative of a current brightness level for controlling brightness of the display;
• and
• associating the current ambient light level and the current brightness level with the user identifier.

A system for associating a brightness level and an ambient light level with an identifier for a currently authorized user comprising:

• means for generating an ambient light level signal corresponding to a current ambient light level on a display;
• means for generating a display brightness level corresponding to a current display brightness level;
• and
• means for associating the ambient light level and the display brightness level with the identifier.

A method of adjusting brightness of a display comprising the steps of:

• receiving an ambient light level signal indicative of a current ambient light level on a display;
• receiving a brightness level signal indicative of a current brightness level of the display;
• associating the current ambient light level with a stored ambient light level associated with a user currently authorized to access a computer driving the display;
• determining a preferred brightness level out of a plurality of stored brightness levels associated with the stored ambient light level;
• determining that the current brightness level is different from the preferred brightness level by at least a predetermined threshold;
• and
• adjusting the brightness of the display to the preferred brightness level.
