1. TIME DELAY DATABASE AND ECULIDEAN DISTANCES

2. TIME DELAY DATABASE Goals from last milestone: 1)Choose between Excel or Matlab to use for Database. Done! We wrote code for a Matlab Database. 2)Write code for Euclidean distance. Done! 3) Achieve localization. In-Progress. 4) Construct or use a GUI tool to display coordinate values. In-Progress.

3. TIME DELAY DATABASE For each sample point in the Test Space (180 Total) Receive Onset values from each mic- 4 total Use Onset values to get the abs. difference Create a 1 dimensional (9 element array)

4. 9 element array Create the 9 element array – (x coordinate, y coordinate, z coordinate) – Difference between Onset 1 and Onset 2 – Difference between Onset 1 and Onset 3 – Difference between Onset 1 and Onset 4 – Difference between Onset 2 and Onset 3 – Difference between Onset 2 and Onset 4 – Difference between Onset 3 and Onset 4

5. 9 element array For each sample point.( 180 points) (x, y, z, ab, ac, ad, bc, bd, cd) Write the array in the database Continue the loop!

6. Results (Time-delay Database)

7. Euclidean Distance Once Database is complete, modify it for real- time and Euclidean distance.
