The personality of product features: assigning personalities to medical devices

Anaphylaxis is an allergic emergency. Treatment urgently requires a single does of epinephrine from an auto-injector that is designed as a single-use product. Unfortunately, the auto-injector is designed to have visually confusing cues, lending to misuse of the product. This study examined how visual cues can communicate a mode of use to better inform correct administration of the life saving drug contained in the auto-injector. Lastly, a set of principles was created to help design less ambiguous medical products to help guide a user through the products mode of use in medical emergencies.
