Exercise 8 - Mensch-Maschine-Interaktion 1 (MMI 1)
Exercise 8 - MMI 1
Topic: Qualitative User Study
a) Write a summary (100-300 words) of the lectures on "Analyzing the
Requirements" / "Designing Interactive Systems" (depending on which one
you did already summarize).
b) If you were to design a new meeting-room reservation software for
e.g. Siemens, which people (max. 6) would you invite to a focus group?
Give reasons for your choices.
16. User StudyYour task is to conduct a qualitative user study of KA/PI, an addressbook application for desktop computers and mobile devices.
is open-source and runs on Windows and Linux. The user interface
is optimized for mobile devices with a 640x480 VGA screen and a
hardware keyboard (Sharp Zaurus). On a desktop computer the size
can be adjusted arbitrarily.
The primary target group are power users that want the same application to be running on their PDA and on their desktop PC.
on the PDA is operated with a stylus. A right-click on the touchscreen
is done by keeping the stylus pressed down for about one second. These
right-clicks are very inefficient, and thus seldomly used in KA/PI.
Text is usually entered using the hardware keyboard. The keyboard is
operated with two thumbs. Switching input between keyboard and
touchscreen takes time and should be avoided. KA/PI shares some UI
concepts with KO/PI, a calendar/todo application. As users ar probably
using both KA/PI and KO/PI, the user interface should be consistent in
between those two applications.
KA/PI's user interface has some
usability problems. Find out a many as possible in a qualitative user
study with at least three participants. Create at least four closed
and one open tasks. Closed tasks might be e.g. "Add as much
contact information as possible from a business card into KA/PI and
note from where you know this person". Open tasks might be e.g. "Find
out what types of information you can store in KA/PI."
a report including a short description of the task, the software, the participants, and
the way you have done the evaluation.
all usability problems your test participants have encountered together
with a severity rating and a suggestion for improvement. If it is
difficult to precisely describe a problem with words, add an annotated
screenshot. Please try to give constructive
We plan to give the results to the developer of KA/PI. Please
state in your report (last line) if you permit us to do this. This has
no effect on grading.
Technical Information:A recent version of KA/PI for Linux is installed in the CIP-Pool. Run /home/proj/mi_dm/kapi/kapi.sh for starting KA/PI. A file kopi.sh in the same directory can be used to start KO/PI. All information entered into KA/PI will be stored under $HOME/kdepim/...
If you want to evaluate KA/PI on a PDA, you can borrow a Sharp Zaurus SL-C1000 with installed KA/PI for one day. Please contact Raphael Wimmer.
can import the file test_data_XX.vcf (XX = 40, 100, 400) from the
program directory. It contains a number of randomly generated test
persons. If you want to generate your own test data you can use Barnum with Ross Burton's vCard modification.
