This chapter first reports the findings based on the user testing: overall impressions, working styles, timing information and error rates. It then evaluates the user interface with respect to how the test users found it. After evaluating the effectiveness of the user testing, it gives an informal usability evaluation of the user interface with respect to Nielsen's ten usability guidelines . This chapter ends with a summary of the positive and negative aspects of the system.
While a total of nine participants gave a good indication of the usability of the system, statistical results generated from the user testing information should be treated as preliminary results. For more statistically valid results, a larger number of participants is required.
