Finding 1: Overall All the users finished all the tasks successfully. All users agree that the overall prototypical system is useful and helpful. Three functions that are valued by participants are foods locate, online shopping, and Magic Spoon. Foods locate: useful especially when fridge is full. Online shopping: preferred by participants dont have car/ time. Magic Spoon: drag and drop interaction method is preferred. Learn while playing. 30. Finding 2: Icons are not intuitive enough Home, Back, Add, Remove, Settings, they are command and easy-understand symbols. Food locate, Shopping list, Recipe, are not command icons for everyone. Need to add on description wording. 31. Finding 2: Icons are not intuitive enough Lesson 1: Keep balance between simple design and explanation. Lesson 2: Brief descriptions or tags under icons may be helpful. 32. Finding 3: Not everyone knows Evernote Only one user knows Evernote. Lesson 1: Choosing famous application is important, but not everyone uses that. Lesson 2: Listen to users. Users preferences: Email/ Print/ Text Message. 33. Findings 4: Users Concerns Idea & Price Idea: advance guard, ideal and impossible. Price: High technology brings out higher cost. Maybe it is expensive now, but how about 5 years later? 34.
