my 7 step Design process

for quality interaction design

On this page I will dissect my design process of ONIX. Each project comes with its own challenges and requires different methods and tools to tackle them, this is simply an example of a design process I enjoyed.



About this step: I often start my projects with an orientation phase. I perform a literature research and benchmark to quickly acquire an overview of my design space and already provided solutions. If applicable I'll look for external experts for additional information.

problem definition and ideation

The idea that resulted from this is building a practice buddy who respectfully coach you in taking sufficient breaks.


About this step: Based on gathered information I'll form an analysis of the problem at hand and the design space. Based on this in combination with the inspiration from the literature research I'll form an idea.

design Methodology


About this step: This is where it gets truly exciting. The previous step was about setting a goal. This step is about coming up with a plan to achieve it. I often consult academic design literature to come up with fitting design methods.


In general I tend to incorporate both quantitative and qualitative research in my design process. These insights combined provide a broad and in-depth view of how the design is used and experienced.


image: The project is about a user group who has a lot of variation within their lives. Furthermore, the project discusses issues such as how many hours do you play per week and when do you play? These are hard to answer without qualitative data. Therefore, the prototype was build with data logging capabilities (qualitative research).




About this step: Using my skills in form giving, rapid prototyping, electronics and programming I'll quickly build experiencable prototypes/probes.

user test / validate


About this step: The build prototypes are validated through extensive user testing. Prototypes are build as fully functioning experience probes user test participants can take with them for extended periods of time and use in an every-day context to gain in-depth experiences (qualitative research).

During the project I had several musicians from CVA who participated as user test group. The prototypes were made custom to their needs and feedback.



About this step: Through careful reflection and creating data visualizations I turned the acquired data into useful information.


image: As mentioned before, the designed prototypes came with datalogging capabilities. All user input is stored as CSV file which I can later access. The data visualization is generated through a processing sketch I wrote. The gathered insights are used to fine-tune algorithms and steer open ended user interviews.




image: Only half of the prototypes build for the project. It shows a timeline of work based on user input and quantitative research.



About this step: I tend to work in iterations, working my way up from rough experimental prototypes towards hi-fi final solutions. The design process is steered based on user input.


This creates a flexible design process that builds on user input.
