IFD:Nutzerstudien WiSe1314/Gruppe Anmeldung

Aims of data gathering

During the course "Nutzerstudien" we wanted to know how important security is for students at our age, what they expect from chat apps and what their problems/whishes are. Main focus was also the question of authenticity. For that reason we started to interview a few people from our social environment.

Data gathering: Interviews/Observation

1. Interviews:

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 these 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.

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?

2. Observation:

Next week we want to make some usability tests of the app (ChatSecure) to find out how others deal with the login-process.

Great idea. It is not easy though to see why for an outsider. You could fix it by explaining first, why and how you canged to the topic "login" and because of this it could not be part of the interview process one or two weeks ago.

Data Analysis & Main Results

• App Requirements
  • The user wants an app/program which is used by a lot of people.
  • 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
  • The user wants a simple, intuitive, neatly arranged design, which looks uniform on all gadgets.

• Interface & Functions
  • The user wants an interface, where you can see who is online at the moment and when a contact was online the last time.
  • The user wants to know if the chat partner read the messages.
  • The user wants to send out photos/videos.
  • The user wants to use a lot of smileys.
  • The function "writes..." is not necassary.

• Security
  • It would be useful to have a password for the app.
  • The user wants 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.

There are lots of "the user wants". It would be easier for outsiders to understand, if you could explain why the user wants this (if you know that. Naturally, my request is not asking for inventing explanations! If you only know that users want but not why you could make it subject of further research)

What specifc 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.

Nice proposal. Are you really talking about the log-in or about setting up a new (Jabber) account? Because in my experience it is not easy to set it up, but once you have your account working and data saved, it behaves very well. But please prove me wrong if that is a singular experience

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

Our first prototype for the login process.
