Problem Description

• Reduce toxic food consumed possibility

• Keep food freshness/expiration dates updated

• Keep a right track on refrigerator's temperature and lighting

Related Work

• Most website and mobile apps only support textual information/instructions.

• Many of them are focus on food itself and additive, but ignore the environment and method to store the food.

• Many of the information are either too professional or too complicated for common people.

Website

Mobile App• Good information but hard

for user to remember.

• Very professional, however may not be the thing common people want

• Passive: with no visualized information and interact function

Our Solution

• Provide live refrigerator information

• Keep track on all the food user purchased and build inventory list with detailed information for user to interact.

• Send warning and reminding when foods are going bad

Tasks Overview

The functional prototype followed three basic tasks:

Food Storage History Review

Warning Summary

Food Inventory Maintenance

Lo-fidelity Prototype

Our prototyping progressed throughout the project:

• Paper Mock Ups• Balsamiq Models• Interactive Website and

Mobile Application

User testing performed on our

Balsamiq model helped shape

the future of our program• Witty names• Ease of navigation• Labeling of graphics

Mid-Fidelity User Testing

Our primary interactive prototype was a mobile application.

• Android Operating System• Some functionality was dictated by system

User Testing

User Testing (contd)Rank Description Suggested Changes

4 repeatedly go back to previous screens in order to get back to home screen

add a home screen button

4 strain eyes to see words make font size bigger

3 click on selection bar instead of words

lighting excesso view current refrigerator's temperature and lighting

settings

• Future Additionso camera view of refrigerator o recommended recipes for upcoming expired foods o text processing tool (parse items on a receipt)
