user study conditions
User study conditions
  • 26 participants.
  • It is a within-subject user study, all of the participants use both traditional terminals and my menu-based terminal.
  • They first recorded their usage of the traditional terminals for at least 5 times in 5 days, then they recorded their usage of my Linux terminal for at least 7 times in less than two weeks.
results and analysis
Results and Analysis:
  • Hypothesis 1 (accepted): easier to use
  • Reason: Novices prefer menu based interaction style to command line based interaction style, since it reduces memory load, learning time and key strokes.
  • Hypothesis 2(accepted): used more commands and their corresponding extensions.
  • Reason: Users are more willing to explore new functionalities when viable options are presented explicitly.
  • Hypothesis 3 (rejected): able to recall how to complete a wider range of distinct tasks
  • Externalization of task-oriented information does not instigate memorization, thus, less knowledge is ratained after the usage.
conclusions
Conclusions:
  • 1. Menu-selection interact style appeals to novice users.
  • 2. Although externalization of task- oriented information reduces memory load of users, it may not be helpful for knowledge acquisition.
