Course Aims

During the course "Nutzerstudien" we focused on the smartphone app "ChatSecure" by interrelating the security of chat apps. We wanted to find out about the importance of security in chat apps for students at our age. Further we were interessted in generelly expectations they have from chat apps and what their problems/whishes are. For that purpose we tested the app "ChatSecure" with our target group, accomplished usability tests and so developed a varied design to improve the process of creating an account and of signing in.


Progress of work

1. Interviews and target group For that reason we started to interview a few people from our social environment as our target group. So we focused on students at the age of 20 - 30. We reached this test persons personally so we met them to conduct the interviews directly.

2. Analyse and Assessment After that we analysed the results (infinity diagramming) by summing up, comparing and strucuring them.

3. Prototypes and scenarios Then we began to create prototypes. These prototypes also passed through usability tests to further improve the design. For that prototypes we constructed scenarios which had to be accomplished by the test users.

4. Improving Design by Iteration We further improved our design by iteration (five steps) to get our final design.


Data gathering: Interviews

table of interview partner:

Number Age class Course of studies
1 <20 Arts
2 <20 Arts
3 20-25 Science/Engineering
4 25-30 Science/Engineering
5 <20 Fine Arts/Design
6 <20 Fine Arts/Design
7 <20 Fine Arts/Design

Reasons for choosing those people:

We wanted to figure out the differences between the students of Arts, Fine Arts/Design and Science/Engineering. So we chose people from our social environment. Because we are students from different courses of studies (Arts, Fine Arts/Design and Science/Engineering) we had the chance to interview these types of students. Thereby we had a huge spectrum of users.

Form of accessibility:

From the start we were agreed that we want to reach our target group personally by meeting them at the university (fellow students/friends) or at home (homemates). We wanted to talk to them privately to get detailed information and to observe their chat behaviour.


Central questions:

  • What chat apps/programs do you use and for what purposes (one-on-one interviews or group discussions, image, video and link transfer)?
  • Where do you see advantages and disadvantages of your favorite chat program?
  • How important authentication is for you?
  • How should a trustable profile be? What information are important?
  • In what situations you prefer the phone or an E-Mail before chatting?
  • What are requirements for you to use a new app with guaranteed security?
  • How often do you use them and how important they are for you?
  • How important is security for you while chatting with people?
  • What measures do you probably adopt to be safe?
  • What functions and design features do you find most important for a chat app?


Observation

After that we did a usability test with ChatSecure to find out how other users deal with the app.

We wanted to find out if the register and login process is intuitive for the user or not. So we got to know about user's handling with apps and their expectations. We hoped to get suggestions and ideas for a better log in process based on the user's behavior.)


  • What observations during the interviews did we make?

-> here the video can be integrated!

  • What is noticeable during that usability test?

-> results


Data Analysis & Main Results

Nutzerstudien-Authentifizierung.jpg

  • App Requirements
    • accessibility is of prime importance, so the app have to be widespread to make the user downloading it.
    • The app should be for free.
    • For the user it’s important to be up-to-date and flexible with messages. So he/she prefers an app for chatting.
  • Visual Design
    • Complexity takes a lot of time, so you need a simple, intuitive, neatly arranged design, which looks uniform on all gadgets.
  • Interface & Functions
    • It is handy for the user to have an interface, where you can see who is online at the moment and when a contact was online the last time.
    • The app should contain a function to let the user know if the chat partner read the messages because it faciliate the communication.
    • The user wants to send out photos/videos.
    • The user likes to express its emotion with a lot of smileys.
    • The function "writes..." is not necassary.


  • Security
    • It would be useful to have a password for the app.
    • To feel safe, the user desires to have a security warranty.
    • It is important that apps are immune from viruses.
    • Important information, link, photos, videos, … are often sent by E-Mail.
    • Distrust towards apps results e.g. from missing knowledge about safety and smart phone-apps.
    • People use safety-options of social networks (e.g. Facebook) but don’t know, if they really work.
  • Authenticity
    • If you want a trustworthy profile you have to find a good balance between too much and too little information.
    • (To much) Personalized advertising makes the user feel insecure.
    • A “real” profile picture is soothing for the user.
    • Authenticity doesn't loom large for students personally.


Research and problem solutions

What specific problem we want to solve

We want to solve some problems with the login-process and make it easier to use. It's hard and circular to login with one of your accounts, because there are too many steps until you are finally logged in. Moreover the buttons are difficult to find on the interface. Therefore we want to create a new login-process.

Plans – how we want to solve the problem(s)

--> Using the method: other application's test:

First we start to analyse the login process at other applications. We found out that WhatsApp is the most widespread app to chat for our target group, second one is the Facebook messanger.

1. WhatsApp

This application doesn't contain a login process. You only have to choose the app to be online and you directly see all of your conversations. It is quite easy and intuitive.

2. Facebook Messenger

This application functions nearly the same way as WhatsApp, so you don't need a password to sign in.

Our conclusion:

Both applications manage without a password. That's quite intuitive but it isn't quite save. While doing our interviews we experienced that it would be convenient to have a password to have a safety warranty (e.g. in case of losing the smartphone)


First design considerations and ideas

After the intervies, the observations while usability tests and the comparision with other apps, we could draw the first design conclusion and ideas:

1. We want the process of creating an account and signing in as inutitve as possible (comparable with WhatsApp and Facebook Messenger) 2. We want the app as safe as possible (safer than WhatsApp and Facebook Messenger)

first changings/development ideas:

  • additional button for entering a password (if it isn't saved)
  • reduce redundant buttons
  • clarify inconclusive and obscure functions/buttons

Prototypes

Version 1
Our first prototype for the login process contains the additional password entering button if it isn't saved. (at the beginning you can choose if you want to save the password for further use or not) It occurs when you want to switch from offline to online as an extra field.

Version 4 - final version

Our conclusions

Problems we had:

The first user experiences by ourselves with the app "ChatSecure" passed dragging because of difficulties with the process of creating an account. We lost too much time by trying to test the app. It was a huge problem that the app didn't work with IOS.


What did work well:

Our teamwork worked all time. On the one hand inside the course but especially inside our working group because we regulary organised meetings and were always in contact via messaging about the actual state of affairs.

Furthermore we were well prepared before interviewing so that we could implement that while talking to our target group.

Generally we got sufhficient background knowledge for our process of work during the course. So we optained step by step our final design.
