Representative Tasks Finding a recipe Sharing a list Shopping from a list

Lo-fi Prototype Structure

Scenarios

Scenario 2 - Sharing a List Asked the users to share a list. Asked the users to share a list

Scenario 3 - Shopping from a List Asked the user to check items off the list as they shopped.

Experimental Method

3 participants in a grocery store

2 were shopping for their families and 1 was shopping for themselves. 2 shopping for family, 1 shopping for themself

Our main tasks were collaborative shopping lists and recipe searching- things that are often associated with families BUT we also wanted to cater to individuals But why…

Efficiency in completing tasks We measured # of mistakes # of questions Efficiency in completing tasks 2 shopping for family, 1 shopping for themself

Experimental Results

? ? #1 Unclear what was scrollable

? ? “I feel like I have to click everything.” “I didn’t know I could click more than one…”

? ? #2 Share feature seems like too much work…

? ? “…if I'm at the grocery store, I'll text her and ask her what she needs….” “…you don’t really think about what you need from the grocery store until someone asks you….”

? ? #3 Share feature is confusing

? ? “How do I share my list with people who aren’t there??”

? ? #4 People don’t know how to add recipe ingredients to the list

? ? “…Wait what? What do the checks mean? Can I uncheck them?….” “…How do I put them into my list? There isn’t an add button….”

? ? #5 Not everyone has a smart phone

? ? “my wife doesn't have a smart phone…”

Suggested UI Changes

! ! #1 Add a key word search, or categories for recipe results “Recipes need to be alphabetical and need some sort of order – they need sort options”

! ! #2 Make scrolling more apparent on the filters page

! ! #3 Have a recently added section in shopping list “I want to easily see what other people recently added…”

! ! #4 If a contributor is adding an item to the list, make that item get approval first. “I don’t want my kids to add a bunch of junk to my shopping list…”

! ! #5 Ability to skip the filter - or add the ability to select more than one option. “I want to be able to look up Thai food and Mexican food during the same search.”

! ! #6 A way for users to add to a list If they have don’t have a smart phone “I should to be able to select from my contacts or something…”
