The path drawn on the screen but the android device is generated by a simple program that just uses Java libaries to randomly generate 4 x,y pairs on the screen and draw them. The algorithm makes sure that all the x,y pairs are atleast a minimum distance from eachother. The paths are seeded with an incrementing count before each use to ensure easy reproducability of each individual path.

1. /581Project/

• This folder contains all the code for the android project used to record the data

2. /scripts/

• Has all the python scripts I've created to generate output and figures

3. /Figures/

• Contains all the generated figures created by genFigures.py

4. /OutputCSVs/

• This folder has all of the CSVs with the raw location/pressure data collected from the android project

5. /OutputGenerated/

• Contains all the generated binary files using different strategies. Each strategy has it's own sub folder and are detailed below.

6. /Results/

• Contains the results from automated tests like the PRG testing and hamming distance tests.

7. /Screenshots/

• Screenshots of the android app used to record the pressure data.

These are the strategies used to generate the random 1's or 0's.

1. Simple Average

• This is the simplest strategy, averages all the pressure values and then outputs a 0 or 1 depending on if it is above or below the average.

2. Moving average n=5

• This strategy uses a moving average with an n of 5 to compare the pressure value against

3. Moving average n=10

• Same as above but n=10

4. Cumulative moving average

• This strategy uses a cumulative running average for the pressure comparison.
