Persona/Super-user
Since this project really took departure in Lasse, our super-user, it made perfect sense to make him our persona for the design process.
We gave the persona a POV and decided on suitable Design Drivers.
At this point in the process we could list design criteria we wanted our wearable to fulfil. We also brainstormed ideas for how the wearable should look, feel, sound and work. View our notes of both below.
We sketched our ideas.
In the beginning, our ideas for the mother device revolved around a clip that one could fasten on a watch's wristband. Iterating the ideation and sketching process took us further into making mother device a buttons instead. It would go under the wristwatch instead of on the wristband. This solution makes the wearable practical since it's not in the way, and does not easily fall off. The mother-button can also be attached to jewelry such as a pendant or brooch, for people who do not wear watches.
One of the initial ideas for the child-device was a rubber sleeve that would fasten via a hook. Then we thought of the easier solution of a sticker on the back that would attach to practically anything. The child-device is easily removable from the cover for ease of charging.
Prototyping & Testing
After deciding on the universal button-design, we made prototypes in FIMO-clay and also in Rhino that we 3D-printed. We tested these with our super-user Lasse and also asked him to touch different materials such as a rubber headphone case, a rubber spatula and a rubber duck to gain insight on the sensory impact of materials, much like we did during our make tools session.
After gathering the insights from the testing session with our super-user, we researched different sustainable material choices in KEA's material design lab, and then it was time to start making the concept come to life. To see how we did that, check out the Technology section below.
