Shadow Replacement

2. Original Ideas I knew that I wanted to create user interaction
I wanted to do so with little to no work by the user
I also wanted a relatively subliminal output, something you don’t necessarily notice

3. Double- Taker (Snout)

4. Hand From Above

5. Shadow Replacement
Shadows are something that surround us on a momentary basis
Something that we take for granted
So what happens if this shadow disappears? Better yet, what happens if it gets replaced?
Will people notice?

10. Problems Numenta People tracking
Originally I began to develop something just using a normal camera
Problem was that what I did worked a lot better with stereo cameras

12. With out the stereo camera the program had several inclusions resulting in a shaky output
Stereo cameras are very expensive, so I had to think about what I had to work with

16. Ended up beginning to work with Kinect
Kinect can track multiple people simultaneously with out the use of the freeze pose
Can also monitor depth and several other aspects that will be beneficial

17. Basically… The program places a box around the individual
Take the lower coordinates of the box and import those numbers into Max
Implement a shadow and control the way the shadow moves based on the speed of the individual
A stopped person results in a stopped shadow
