This assignment is a hands-on exercise on quantitative evalution. Its immediate purpose is to give you experience conducting a controlled experiment, performing a simple statistical analysis, interpretting the results, and considering its implications to design decisions. Its other purpose is to provide you with enough knowledge of the experimental process to help you understand and appreciate the HCI literature that uses this methodology. The assignment, which changes slightly every year, compares people's mouse-typing abilities on different keyboard layouts. Mouse typing is simply the speed at which someone types, using a mouse, on a soft keyboard presented on the computer screen. Some of the keyboard layouts considered over the years are:
You will work in groups of three, and each group uses its members as subjects. Your group will submit the data collected to the teaching assistant, who will compile the data from all group and hand it back to the class. Your group will then use an unpaired T-Test to check for differences between the typing speeds.
Your group will deliver a substantial technical report that presents the experiment, collects the results, and discusses its implications. Your report must follow the format defined in the above-mentioned handout How to Structure Reports on Experiments in HCI.
