Tablet PC's in Bright Sunlight?

chadma asks: "I'm developing a program to be used on a Tablet PC; the unit will be used outdoors >80% of the time. I've seen some tablets from ViewSonic and MotionComputing and wondered if anyone had any experience or suggestions in the best screen for high sunlight conditions. Has there been any study or anyone with experience that could suggest the colors we use in the design? Would a white background with black text be most appropriate?"

May be way out there...

But have you considered oh I don't know...

Allowing your users to choose the colour scheme of the program, to provide the best visability in whatever conditions they're in?

Outside in the sun means sunglasses

Use more contrasty colors (black and white are good) in order to make your text stand out from the background. Let the TabletPC owners and makers worry about glare, but make sure that your text is easily visible through polarized sunglass lenses.
