Sammanfattning
For most people, the act of going to the bathroom is not a big deal. However, for people with
bowel disfunction, this act can be thought of differently. Bowel disfunction can happen to
anyone as a result of an illness or an accident. Some people with bowel disfunction use
transanal irrigation which is a procedure where the user instill water into the bowel to loos en the feces and to stimulate bowel movement. Using transanal irrigation allows the user to
choose when and where to empty the bowel. This enables the user to regain control over a
part of their life. The current smart transanal irrigation product which is being redesigned in
the thesis have some usability issues and the review functionality is not widely adopted which
would be beneficial to solve.
The aim of the thesis is to create prototypes which provides a more intuitive and positive
user experience when performing transanal irrigation. Firstly, the project started with three
para-llel phases to create understandings: interviews, digital prototype tests and physical
prototype tests. Secondly, the insights from the first three phases have been used to create
requirements, focus areas and guidelines to influence the concept decision and the next
designs. Lastly, a final prototype was designed to be used for further testing.
The final prototype uses a combination of physical buttons which ensures that the user feels
in control when performing the treatment and a resistive touchscreen which enables an easy
way to interact with interface. The experience of reviewing the treatment has been simplified
and put in the device, from previously being in an app. This enables the user to faster and
more conveniently make the review. The interface also includes information boxes and more
informative error messages which lets new users learn about the treatment.
This project is thought of as one iteration of the development and thus multiple more needs
to be made to cover more areas. The result of this thesis helps the development of the unit to
take a step in the right direction in terms of further considering the needs of the users.
