CIS 376 Project 1
Fall 2011

Your first project will give you an opportunity to do modeling of user tasks. You will need to identify 3 functions in the same program (e.g. Winzip or Acrobat Reader). For each function, you will need to identify one situation in which the function works well and one situation in which the function works poorly.

For each of the functions, build Keystroke Level Models for one situation in which each function works well and one situation in which the each function works poorly. Estimate the execution time (including mental operators) for each model. Measure the actual execution times required for 3 users to complete each of the 6 situations.

Write a GOMS model for each of the 3 functions. The GOMS model should cover both situations modeled for each function. You should then calculate the estimated times to execute each function. Compare the estimated execution times for the GOMS models, the keystroke models, and the actual execution times.

The write-up for this project is due 2 weeks from Wednesday. Your write-up for this project should include: the models, your assumptions, the task scenario descriptions, calculations, relevant data displays, statistics, and your conclusions.
