Auto Gamma / Dimming of screen

**skippy76** · 05-13-2004, 01:12 PM

VOICES currently has a button that enables you to apply / remove the Gamma, providing a brightness control for use at night.

An automatic system would be a big advantage. There should be two options when applying an automatic switch:

- By time of day, manually configured for on and off.
e.g. gammaon=19:00
gammaoff=05:00

- By long and lat value, based on a sunrise and sunset calculation. Code for this can be found at:

second method would be best

The first one is what other programs use and is manual and should be an option for those who dont have GPS...Remember not everyone ownes a GPS (yet)

I personally like the second option the best becasue it requires no setup from the user except for initial setup.

Good work

Both the options will be implemented

Impressive! I think there should also be an option/voice command for a manual gamma change. I find that it not only depends on where the sun is at, but what i'm doing with the computer. IE. During the day its gloomy and i want it dimmed...i could say: 'computer dim display'
If its night and I'm watching a movie i may want it brighter so i could say "computer bright display"

etc...

is there a way to add a shortcut on the desktop that can do this? like media car kindof has?

why not just link it to the headlight/dash light circuit? When you turn on your dash lights, it's typically low light or night time and the ideal time for the screen to dim...
