Vision, Orientation

Maybe a multi-axis accelerometer could provide useful extra input for computer vision applications? By sensing up, the direction of g, the acceleration due to gravity, an accelerometer could provide an extra clue for vision algorithms searching for floors and walls: the first should be perpendicular to "up", the second parallel (usually!).

If your sensor isn't stable, or is always upright, this input won't be so useful, of course.
