Abstract [en]

Gait analysis can be described as a study of human walking patterns. This is very useful in health care, since gait analysis can reveal important information about a patient, and be an aid in diagnosis and rehabilitation. Today gait analysis is done either by qualitative visual observation of the patient, or in resource demanding and advanced laboratory settings. Many studies have been done in the search for new technical solutions that enables quantitative gait analysis outside of the laboratory.

The goal of this thesis was to evaluate the usability of a new gait analysis system and to find out how the user interface could be better adapted to the end user’s needs and goals. This was done by defining and using suitable methods for learning about the users, evaluating the system and by defining usability in a clinical setting. A redesigned prototype was then developed and tested.

It was found that the original user interface had many usability issues and was in need of better adaption to the intended user group. Through user research personas and key user needs could be determined that became the basis for the design work, along with guidelines from previous studies within the field. The redesigned prototype was tested on potential end users.

It was in this study determined that semi-structured interviews are suitable for learning about the users. Usability evaluation should preferably be done using a combination of evaluation that involves real end users and evaluation by usability experts. Guidelines for usability in clinical systems could also be defined. Considering the redesigned prototype, the users saw a great potential, and could see themselves using it in the future. The testing determined that the redesigned prototype managed to solve many of the usability issues found in the original design.
