A simple tool for capturing user input like mouse positions, movement, key strokes and plotting them.
For capturing mouse movement and keystrokes, just run the java code and press CTRL + Q to save. If you have trouble starting it, import it as a Eclipse project and it should work.
Remember: CTRL + Q saves the log files and overwrites the old log files. So you might save your files after a run.
For starting a new capture, I suggest to run the Code, and press CTRL + Q if you're ready (that will override the existing data). Then capture your run (or let the users do the tests) and at the end, hit CTRL + Q again to save the data until to that point. You can then end the running java code without writing that back into files.
Standard output variables includes (first three in summary.txt):
- time duration
- distance covered by mouse movement
- number of clicks
- a csv with all the position data of the mouse (positions.csv)
The java code makes use of the jnativehook library (you guys are awesome!) which can capture mouse gestures and keyboard movement system-wide.
You can visualize the data by applying the plot.py program (you'll need python installed). It will plot all the given positions from positions.csv to a transparent PNG-image, which you can then combine with a screenshot of the scene the capture took place.
You may want to customize your screen size and the line color, depending on the background of your screenshot you use to make the captured data visible:
screen = (1366, 768)
line_color = 'black'
There's some sample data also in there, and you see a capture of me playing Angry Birds:
This code is mostly untested and was written for quick use in the course Human-Computer-Interaction. It should work on Ubuntu 12.04, no clue if it works on Windows. Use at your own risk.
