Week 12 User Testing

In order to improve our prototype, we tested our prototype and obtained some feedbacks from people.

Testing plan

Introduce our concept to the user at first, then tell them some limitation of the prototype that there are only two choices for them to choose, the "Red light" and "Green light".

Task

Use the prototype with one of our team member, let your "mood" display on the phone case.

Observation

observe whether user can finish the task smoothly, focus on the facial expression and the actions of the user to get feedback.

Interview

Interview Questions

1. Have you ever feel confused during the process? If yes, please tell me the reason.
2. Do you think the prototype reach your expectation？
3. Do you think this prototype can help you make more friends in real life?
4. Please give some suggestions to help us improve our prototype.

Feedback we obtain

• The colours are too few, need more colours to represent different mood.
• Young people fond of using emojis to represent their emotion.
• It is awkward if two people's phone case display the green light and start talking, but they do not have a common topic to communicate.

Improvement

• Add a screen on the phone case which can display the emoji that user choose.
• Add more colours such as blue to represent sad.
• Let the phone case can connect with Facebook, only when you meet people who are your Facebook friends or in your "people you may know" list, the phone case will work. This can avoid some awkward situation, people who are your Facebook friends or in your recommendation list usually have something in common with you.

Observation and interview raw data

• Interviewee 1

1. In the process I want to know how to adjust different lights. Is it possible to turn on the lights when the distance of fb's friends is close?

2. It is very fun.

3. Yes, I would like to have a display that shows my mood so that I don't want to talk to people around me or feel sad.

4. More want to see the mobile phone application you built, it is more interesting if the color of the phone case can be selected in the application.

• Interviewee 2

1. Not confused, this prototype is easy to use, just press the button and change the mode.
2. I have no idea actually, this idea is interesting, but it is still a little bit awkward that two people do not know each other to talk in my perspective.
3. It can contribute to some extent, but I think it still depends on the personal characteristics, shy people may be still too shy to talk, they may set the “red light”.
4. I think you can add more colours, and people will not be satisfied with happy and mad, other emotions like blue, grey should be added to present different mood.

• Observation

The user can use the prototype smoothly, and she can change the two different modes. But her facial expression looks like a little embarrassing when our team member start talking to her (after they both set the “green light”).
