Chapter 7 Testing & Experiment results
Later, the videos were analyzed and for every video a number of notes were
made, these notes helped the design of the system a lot since they describe what
is in the scene and what action is being performed by the actors.
7.2 Test plan
Usability is one of the important aspects which determines product’s acceptance
by users and its exhaustive use. The ease of use is now becoming an increasingly
important factor in the purchase of software. A software product may have great
features and wide array of options but if it is difficult to use and is complicated,
then there is a strong chance of an otherwise ‘good’ product to get branded as
‘bad’ product. While developing and testing the software, one must take into
consideration is that both a novice and a seasoned user are able to use it with
relative ease.
A focused testing effort on usability aspects of the product leads to development
of more usable product and satisfied customers.
The testing will be carried out by students who work at the MMI lab. A task list
(Appendix A) is giving where testers have to complete a certain series of tasks
using the system. The first few tasks that were given were relatively easy to do,
and everything was explained exactly, but later on the tasks were open and the
user can do what he/she thinks is the right action, this is done so we can measure
the learn-ability of the system. After finishing the test, the users have to fill in a
debriefing form (Appendix B), where we ask the testers on their opinion
regarding the system, and to give a grade about several things like (difficulty,
user friendly). We also asked the testers to give us three things they like and
dislike about the system. This is done to get a better idea about how the testers
think about the system and the usability of it.
