For exle, if Chris Smind Joo are bothng an ysis, the identifier might be CS1 or JK75. If both a heuristic evaluation and a think-aloud usability study were

6、me of this UAR when you talk about its relation to other UARs. Make the name as short as sible (about three to five words) but still descriptive and distinguishable from other aspects of the system. If this UAR is about a problem (as op ed to a good feature), make sure you have a name t describes th

7、e problem, rather n a solution.;s3=This is the objective supporting material t justifies your identifying the aspe worthy of report. This section needs to contain enough information for a reader of this UAR to understand what triggered the report. For an HE report, for instance, this could be an ima

8、ge of a cluttered screen and the heuristic about aesthetics and minimalist design. In a think-aloud study this is usually what was on the screen (a screen shot or description), what the user did (keystrokes, mouse movements), what the system did in response to any user actions, and what the user sai

9、d. You need to include enough pertinent information about the identification of an aspect for the reader to understand what the yst was thinking when the aspect was identified (for HE) or what the user was trying to do when the aspect either hindered or facili ed his or her progress.;s4=This is your

10、 re ion of the evidence. t is, for a think-aloud usability test, why you think what happened happened, or, for an HE, why you think the aspect was designed the way it was. You need to provide enough content his explanation for the reader to understand the problem-even if they do not know the system

11、oras well as you do.;s5=This is your reasoning about how important it is to either fix this problem or preserve this good feature. This includes how frequently the users will experience this aspect, whether they are likely to learn how it works, whether it will affect new users, casual users, experi

It is not nesary to have a solution as soon as you identify a problem-you might find after yzing the wholeerface t many problems are related and c

However, if you do proe asible solution, report anypotential design trade-offst you see;s7=It is often the case t UARs are related to each other. This is where you record which UARs this one is related to and a s ement a

It is a common mistake to enter the po er o a newly created UAR, but neglect to go back to the previous ones t it relates to and update their UARs.;ponents(); jButton1.setMnemonic(KeyEvent.VK_D); jButton2.setMnemonic(KeyEvent.
