HE1 - Good Feature
Succinct description:
Users can know what he has to do was just to select a picture from the box.
Evidence for the aspect:
Heuristic: error prevention
Interface aspect:
A textbox on the left tells the users only to select a picture not the other things.
Explanation of the aspect:
For the new users they maybe not know how to reset the screen picture.So they may kake some errors.But when we show the textbox on the left ,they can know what they have to do was only to select a picture.
Benefit of the good feature:
The users will reset the property qiuckly . This will prevent errors for all types of users (novice, occasional, and skilled).
Solution:
I cannot foresee any problems with this implementation.
Relationship to other UARs:
None when the original UAR was written.

HE2—Problem
Succinct description:
Many projects for setting the appearance.And some of the projects are similar.
Evidence for the aspect:
Heuristic: Aesthetics and minimalist design
Interface aspect:
There are ten projects for the buttons and windows.Four for the color,three for the fontsize.There are maybe many different projects.But some are so similar.
Explanation of the aspect:
Ten projects for the windows and buttons ,four for the color,three for the font size.We can count how many different projects there are.Though it can offer many projects for us to select.But people don’t like the same projects.
Severity of the problem:
The users may find that they spend so much time but get the same appearance.So they may feel frustrated at it.
Solution:
At a minimum, analyze whether we can unit some similar projects and try to cut the number down.
Relationship to other UARs:
None when this UAR was originally written.
UAR Identifier
HE3 – Good Feature
Succinct description:
Some window setting effectcan appearon the other windows
Evidence for the aspect:
Heuristic: recognition rather than recall.
Interface aspect:
For example the setting of the screen saver can appear on the background.
Explanation of the aspect:
When the users reset the screen saver and then he goes to the background ,he finds what he sets havemade effect.Now he knows he has changed it successfully.
Benefit of the good feature:
This can be very useful when the users make many settings .At that situation he may be confused by so many tasks.So it’s good to show them.
Solution:
I cannot foresee any problems with this implementation.
Relationship to other UARs:
None

HE23—Good Feature
Succinct description:
The good windows show the different settings’ effect.
Evidence for the aspect:
Heuristic: Help and documentation
Interface aspect:
Explanation of the aspect:
When we don’t know how to control the settins’ effect,the windows could show them and tells us the different effect.
Benefits of the problem:
This can help the users well to do their setting work.The settings’ effects show directly on the windows ,the users can properly do it.
Solution:
I cannot foresee any problems with this implementation.
Relationship to other UARs:
None

HE5—Problem
Succinct description:
When the users input the numbers or others to reset ,the panel has no projects to tell the users what the problems are if we hava made errors.
Evidence for the aspect:
Heuristic: Help and documentation, specifically that Help needs to be available at all times.
Interface aspect:
The numbers input should be informed.
Explanation of the aspect:
When there are no such projects that informed how to do it right or inform what errors are,we can’t make lessons from it ,maybe we will do it again.People prefer to be informed as possible as we can.
Severity of the problem:
It maybe cut down the efficient of our tasks for resetting and make some small errors but could make our use of PC discommodiously
Users may
Solution:
show a message when the errors occur and tell how to recover them by making a dialog box.
Relationship to other UARs:
None at the time this UAR was originally written.
