Designing for Intuition
How could we design for intuitive placement & usage when the object is so fundamentally unfamiliar?
Early prototypes from the internal team were regularly placed incorrectly on the finger. This was combined with user confusion over how the vibration was controlled.
To uncover the solution to these key UX challenges we engaged in deep user testing. Over 12 different prototypes were built and tested with a cohort of 25 representative users.
Designing for Approachability
The answer to the placement challenge was a gently curved overall shape, mimicking the bend of a finger. This eliminated errors in positioning almost completely and significantly improved UX in the process.
This unlocked the overall design of the product. Throughout the physical design and development phase we combined this form with a soft approach to detailing, aiming to bring familiarity and approachability to an inherently unusual object.
As of June 2021 the finished PA is now shipping with Letsgetchecked kits.
