Project 4: User interface for logging food intake and activities

Muhammad Zaman, Warren Trinh, Thanh Le, and Christine Liang


What is it

What is it?

  • The project that we are working on is an online application where users can register their daily diet information and physical activities into a calendar log.

  • The application will allow diabetics to track their progress and provide notes on how to improve their diet. 

  • Our primary focus is to test the application for usability issues and suggest ways to improve the app. 

  • We are also assigned the task of improving the look and feel of the site by changing the CSS.


Usability heuristic problems

Usability/Heuristic Problems

  • There was no way for the user to delete and edit meals/ meal items / activities 

  • User had to search the exact name of an item to search for it

  • There was no way for the user to check what meals have been added beforehand

  • The website did not provide significant feedback to the users

  • The site is incomplete and the glucose functions that the diabetic user would need are not supported


Usability research methods

Usability Research Methods

  • Two Iterations of Usability Testing

  • 12 users in total

    • 8 users for first iteration

    • 4 users for second iteration (two returners)

    • At least 1 Diabetes Patient per iteration

  •  Target User

    • Type 2 Diabetes Patients (Primary)

    • Dieters

    • Nutrition/Health Enthusiasts

  • 30-40 minutes

  • Background Questionnaire

  • Pre-Test Interview

  • "Think Aloud" Testing

  • Post Test Interviews


Pre test interview

Pre-Test Interview

  • Initial impressions of the interface

  • Expectations from the options on the website

  • Is the terminology understandable?

  • Rate the ease of use based on initial impressions


Think aloud testing

"Think Aloud" Testing

  • Hardware/Software:

    • Laptop

    • Screen capture software

    • Microphone

    • Webcam to capture facial expressions

  •  Present various scenarios for the user to complete

    • Between 5 and 10 scenarios 

    • Always the same set of scenarios for each user


Tasks

Tasks
