- Bad linearity of progress
- Confusion between restriction/preference
- Users might select preferred items and restricted items in arbitrary order
- User will can make mistakes on his restrictionsrestriction entry, only to discover it too late in once on the dishes page , and have to go backto return to edit restrictions.
Although some of these issues have been resolved, more brainstorming and discussion is needed. The depth of the menu may also have been a factor in what we observed. Our interface shown only eight total dishes and sixteen ingredients. Our results could have been much different with 100s of dishes and ingredients. We may need better ways of displaying information to reduce cluttering.
