Dimension | Pros | Cons |
---|---|---|
Learnability | > There are several dimensions that the user can search based on, so the user can learn quickly what sorts of keywords to input. | > Since there are a few search boxes, the user may not know at first what types of keywords to use to get good results according to what he/she wants. |
Visibility | > Uploading photos and entering comments gives feedback right away. | > The view page does not show the pictures in the same series (uploaded in the same date by the same person) as the current picture. |
Efficiency | > There is only one search box for all types of search terms. The user does not need to categorize his search term first. | > The user needs to upload one photo at a time and click "Add Photo" to add the next one. There is no way to upload photos in batches. |
Error Prevention | > Photo information can be corrected using the Edit Photo page | > Some people may supply incorrect photo information, which leads to contaminated search results. Since only the uploader can change the photo information, that error may persist for a long time. |
