Designing Interactive Systems (Wintersemester 2015/2016)

Dozent: Prof. Dr. Patrick Baudisch (Human-Computer Interaction)


How would you improve the iPhone or create a web site for blind

users? How do you find the best solution and how do you know that it is

indeed the best solution? Unlike computers and programs, humans are hard

to model. The design of interactive systems is thus different from

other areas in computer science in that one has to borrow from Design

and the empirical sciences. The class consists of two parts that run in

parallel: lecture and project 

A. Lecture: Every week I will teach one of the basic techniques in usability 

  1. Design: brainstorming, sketching, presentation, design critique, paper prototyping, refinement
  2. Engineering: rapid prototyping, implementierung in QML, C++, Qt
  3. Evaluation: user-centered

    design, design patterns, discount usability evaluation, heuristic

    evaluation, interviews, quantitative user studies.

B. Project: 

parallel to the lecture the students will apply what they have learned

in a group project. Each week represents a different phase of the

project development cycle. You will form teams of 3-4 students, generate

ideas, sketch, gather input from actual users, implement 2-3 ideas a

paper prototypes, and finally execute the best idea in actual code in

C++ under Qt. You will present your prototypes to each other in design

critiques and you will iterate and refine based on the feedback you

receive. In week 5, two team members per team give the first

presentation to the class; at the end, the other two team members

present the final outcome including a simple demo. The lecture is taught

in English.
