After interviewing doctors and parents of adolescents with arthritis, the most common problems were joint pains in fingers. This usually occurred when adolescents would be in school and hold a pen for too long. As an opportunity, we focused on designing a writing tool that would keep the hand in a neutral position and prevent fingers from gripping and pinching.
Stiff material test
Adjustments of form
Additional finger holder
Adjustments of holder
Added more space
The initial model was
too wide and did
not stay on
Grooves were added for stability, but the finger did not feel comfortable
Tested with pencil to determine the position of its placement
Modified the curves of the prototype to fit the hand
We started with simple ideations and created clay, wooden, and PLA models to further conduct user testing. This helped us consider varying hand sizes and grips to arrive at a universal design with two different tool sizes.
We developed a style guide and logo. The product was packaged using a PLA vacuum closure on printed cardstock.
