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.

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”).

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

After the introduction, the user can quickly understand the intent of the prototype. When he left the prototype with a certain distance, he knew that the light on the prototype could be restarted after entering the tester again.

Interviewee 3

1. Can I just choose to display the emoticon package? I don't really like to keep lighting up.
2. Completely reached. It is a good understanding of the function of this phone case.
3. Yes! If I see someone using such a smart phone case, I will feel cool and will go up to talk to him.
4. The color of the light can be more, or there are other ways to replace the display of the light. The lights are sometimes glaring.

Observation

The user can participate in the test with the companion, and the two can smoothly adjust the light within the distance. At the same time, you can choose different expressions according to your own interests.

Interviewee 4

1. It is easy to use I think, and I do not feel confused at all.
2. This is a new idea which is exciting and fun to use, and I think it reached my expectation.
3. Yes, I think this phone case can. Because this can help you know the emotion of the people you may talk to and can avoid some unnecessary situation.
4. Do you know that people in our generation love to use memes and emojis to represent our emotion and mood? I think you can change the light to a screen which displays the emojis or memes.

Observation:

It is easy for the user to use this prototype, and during the process, she looks happy and positive, when she changes the lights, she looks like surprised.

Interviewee 5

1. Not really actually. Before user testing, you provide a detailed introduction of your concept. On the other hand, I could clearly comprehend your purpose via poster and brochure.
2. From functional aspects, the prototype achieves it. However, the aesthetics the prototype need more focus on the design of the phone case.
3. Absolutely, I like your idea and I want to have a try if the prototype produced and the design of phone case could be more attractive.
4. As I mentioned before, the design of the prototype could be better and more attractive for users to use in the future.

Observation:

The user is satisfied with prototype and inquiry more things on the production of the phone case and how to link this device with Facebook.

Interviewee 6

1. Sometimes need to consider which light represent which kinds of mood may confuse for me. If there have real emoji could demonstrate on phone case.
2. Partially achieved my expectation.
3. Maybe. To be honest I’m not sure about that if I’m an introverted person really could communicate with people who I don’t know even I know in the real world.
4. The device could be d connected to the application on the phone, and user could control the current state through the application which is more easy for them to use.

Observation:

User feel confused that don’t remember which light represent which light and if they don’t have an introduction it will be mess for him.
