    Hello,

    I'm trying to find a way to correct the perspective of a projection which shows a room looking through the vantage point of a window. The viewers will be appx. 20' away from the screen and will be moving left to right. I would like to have the image account for the perspective change as they move left to right. Is there a method to capture the location of the viewers through a camera and drive a skew on the x axis based on their position in the room?

    I think this was done in the most recent version of Mission Impossible ( the movie series).
    There they used an eye tracking system, which is good only for a single viewer.
    As everyone will be in a different position their perspective will change.

    In reality I don't think this has actually reached actual tech yet, or not at a achievable price point.

    Couldn't you do this with a curved screen and a panoramic shot of the image?

    I agree with @Amiers. This would be the best method for all possible viewers. This is the basic principle of the eyes that follow you in paintings/sculptures.

    If you really want a tracking thing for some art installation. I would investigate XBox one connect. I have no useful info but I am sure there are people playing with them doing this type of capture. Then you could use a live video rendering software like isadora to take some imput out of connect into the x values. I would look into communities playing with connect to see what hacks they have put together.

    also Wii motes could do things... if you can put IR LEDs on the viewers
