More Straps, Please
One notable issue with the strap sleeve is obstruction when the wearer had it opposite to the person trying to find them. To improve its features, a sleeve on both straps would prove much more effective than one, essentially making the sleeves visible from both sides of the guide rather than just one.
Testing the strap sleeve further with plenty more user tests would also be helpful since we only tested on 20 people total.
Beyond the Technical
This particular project taught me the possibilities of UX outside of digital iterations that I commonly resort to in other projects. As we explored and iterated, concepts beside digital ones captured our attentions, and to then reframe our minds to avoid the typical route led to interesting and effective prototypes.
