The preparatioin was quite easy for me, because I’ve already known the test subjects. It was fast done to find a fixed date. During the interviews II realized that I sometimes had to look between the lines to filter what my interview partner really thinks. So I got the most usable answers by questioning their answers (“Why do you think so?”) or ask a question like “So, do you think it’s like…?” I used pen and paper, I haven’t had audio equipment, but the written answers had been useful. | The preparatioin was quite easy for me, because I’ve already known the test subjects.

* Test subject 1: | |||
She is not quite satisfied with her current chat programs. Sometimes she holds back her opinion about political references and don’t give an access to her adress, e.g. in facebook. She’d like to have a chat that’s secure, but she only uses it, if all of her friends would use it, too. | |||
* Test subject 2: She knows about the dangers of someone that could spy out her messages, but it doesn’t bother her at all. As long as it isn’t someone that she knows and it could have consequences for her, she not interested in a secure chat. For her functions and look is more impotant. | |||
* Test subject 3: She is a quite cautios person that feels insecure all the time when being in the internet. She don’t hold back with her opinion, but writes messages with the perpetual feeling of “I can be watched now.” She would appreciate a chat that is secure, but one that is instinctively and simple to handle, because she gives up pretty fast and changes the app when she needs a longer time to figure out the single functions. | |||

Data Analysis | ==Data Analysis== | ||
We searched for specific answers in the interviews and looked how it could help to spot a problem. Then we put all our results together and created an affinity diagramm. | We searched for specific answers in the interviews and looked how it could help to spot a problem.

What we learned from our user research: We got a lot of information about the requirements and the possible use of a chat application. The most important features people wanted to be part of such an application where group chat functionality, image transfer, smileys and an easy to use but appealing interface. People often want to plan parties in a chat, so the group function could be necessary and image transfer is also an important factor of communication for most people. | What we learned from our user research: We got a lot of information about the requirements and the possible use of a chat application.

It was also interesting for us to find out that the main percentage of the users know about possible security issues: | |||

However, they did not try to find an alternative. Related to this we also found out that people using chat software for business had much more concerns about their personal information and especially the topic and content of the talk then the private users. | However, they did not try to find an alternative.

Since insecurity in their currently chats doesn`t bother them much, they just haven`t thought about a secure alternative yet. Most important thing has always been, that all friends use the app/chat. They would change to a secure chat, where all friends are logged in, though. | Since insecurity in their currently chats doesn`t bother them much, they just haven`t thought about a secure alternative yet.

Heuristic analysis | '''Heuristic analysis''' | ||
To improve our prototype, we did a heuristic analysis to search for specific problems in the chat. This analysis is divided in ten subitems. We had been going through them all and found some problems which we wanted to take care of. For time reasons though, we couldn’t involve them all and since we didn’t know how the finger print item works for expample, we concentrated on the more realizeable problems for us. | To improve our prototype, we did a heuristic analysis to search for specific problems in the chat.
