Note:2 or more subjects required. Can be students themselves.
Print out a number of these and run at least two people (not yourself) on the experiment described. If you've got time, run lots of people.
Analyze and compare performance of the two devices
Find tasks with big differences between devices.
IDTest.exe produces a text file called IDTest.dat. Rename it, save it, ship it home, copy it into a spread sheet.
Plot time vs DI (ID?); compare to Fitts' model (intercept+slope*time).
You shouldn't need the sources, because we've already installed it on the lab machines. In case you'd like to try to run these on your own machine at home, here are the files.
You may have to thrash around with java to get things to work, though. Better to run it in the warm, secure, and comfortable HCI Lab.
The ID Test is written by Shuman Zhai's colleague (and manager) Barton Smith, in Java, partially for this class. You can download it Here
