Position detection in a room

Laser_Developer:
jicx,
This can definitely be done. Do you have a budget in mind? Have you considered what kind of software and outputs you would need?

At this moment, the project is only in the initial phase as yet. Therefore, I don’t mean that is in a strict sense, but as I wrote above I have been thinking to use Arduino, and it is also possible to use Processing, openFrameworks, Max, Kinect etc. if necessary. Concerning with the budget, I am not sure yet. Maybe maximum 1000$ ?

These is major criteria, though:

  1. It is very often not possible to hung a camera or Kinect on the ceiling. Otherwise, an organizer of festival does not allow us to set it up enough time.
  2. With the similar reasons, it is not possible to install many sensors on the stage. (If the ultrasound sensor has a very wide beam, it looks like it is possible.)
  3. The condition of light can largely change, such as sometimes a lot of lights, sometimes almost obscure. Thus, it does not work with a normal camera, but it is OK with an infrared camera or Kinect.
  4. For example, Mocap has many dots on a body of dancer. In this project, it is not possible to have anything like this.

Thanks.
