- Learnability
- Items can be dragged and dropped in the managing mode to different wishdexes, which is a model that is learnable because it provides is externally consistent and has a natural mapping.
- The use of three basic panes (wishdexes, items, item information) for both exploring and managing provides good internal consistency.
- Visibility
- The user can easily see if he is in the Explore or Manage mode at the top of the page.
- Switching between panes will be frequent and must not have long loading times to prevent issues with feedback.
- Efficiency
- Similar to the "Hipmunk" design, providing item information on hover is a good example of anticipation.
- All three panes cannot be viewed at once, which requires heavy use of the back button in viewing multiple wishdexes while exploring.
- Error Prevention
- Similar to the "Hipmunk" design, providing item information on hover is a good example of anticipation.
- Error Prevention
- Although the Explore and Manage modes are visually separated, their action sets may not seem disjoint because they involve similar navigation patterns. This may cause errors, particularly if the mode buttons are not in the user's locus of attention.
Overall Analysis:
- Learnability
- Use of Facebook, Twitter, and email icons is externally consistent with many other websites.
- Heavy use of images for wishdexes and shopping items allows for good information scent, and is consistent with the design of other shopping websites.
- Familiar icons (sharing, adding, # of likes, # of comments, editable) allow for affordances for understanding the meaning of icons.
- Visibility
- There may be feedback issues when the user attempts to add a new item using keywords or a URL because of the time needed to process the query. Progress indicators will definitely be needed.
- Efficiency
- Filling in the item information using a query of URL or keywords makes use of defaults and reduces the time needed to add an item.
- Login will only be allowed through Facebook Connect, providing efficient account creation by using preset information for a user's profile picture, name, email, etc.
- Error Prevention
- There is currently no way of recovering a deleted item, but an undo feature in the managing designs could be easily added.
