...
- Restrictions
- Unclear whether checking item 'includes' or 'excludes' it
- Item preference selection inconsistent between 'restrictions' menu
- 'Partial checkbox' for partially-restricted item groups is unclear
- Some food categories were obvious (chicken is obviously under 'protein'), some were not (is 'peanuts' under grains?)
- Users appeared to understand that checking an 'item group' meant checking everything beneath it
- Right-pointing arrow to indicate 'folded accordion' was well-understood
- Groups
- Not clear if checking 'vegetarian' is reversible
- Some users simply selected 'vegetarian' and did not attempt to 'de-select' chicken
- Item browsing
- Not clear at first that this is *not* an ordering system, just a menu system
- Not immediately clear what selecting 'happy face' did (reordered preference list, moved preferred items towards the front)
- One user wanted to be able to 'dislike' food; not sure if that would cause even more confusion
- Use of 'neutral' face to indicate lack of restriction/preference is confusing; suggest happy face (and excited face for preference)
- Some users thought X/neutral face/happy face meant 'amount of ingredient in food'
...
- Unify preference/restriction editing menu menu
- Instead of X/neutral face/happy face, use 'disgusted' face/happy face/excited face
- Use clearer categories than 'grains/fat/protein' (where are peanuts?)
- Drop checkbox interface entirely
- Perhaps preserve 'restrict all' button?
- Use same interface for 'edit
- Clarify how to switch between menu and restrictions
- Big, eye-catching arrow
- 'Directional' for consistency; the menu is to the 'right' of the preference restrictions
- Remove ability to edit 'generic' preferences from menu viewing; only list selected items. Decrease UI clutter
- Using 'leading' phrases to indicate what to do: "what can't you eat?", etc.
- Add 'undo' button to indicate actions are reversible; grayed out when no actions are possible
