As far as > ease of implementation I suspect Why wouldn't you do autochromaticity to adjust colors to match ambient lighting? For example many monitors allow color balance settings to match indoor lighting. This is useful for doing photo/printing work to ensure that what you see on the screen appears the same as what you print. The human visual system automatically adjusts the perception of colors to filter out light sources that aren't perfectly white. I also know people who replace indoor lights, and/or adjust color balance of their televisions to match indoor lighting (since it's not the same as natural light). For example there are several perceptual experiments in which it has been shown that even with monochromatic light sources you can perceive colors. Wouldn't we want the HMD color balance to match the environment, so colors are perceived correctly? Just a thought. :-) -Paul -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org Please, *PLEASE* don't subscribe through a forward/expander/false domain
