Crafting a Leather Self-tracking Device for Pollen Allergies.

In this pictorial, we offer an overview of the design and step-by-step guidance on crafting a leather self-tracking device for pollen allergies. We designed the device to support patients’ daily lives allowing them to track symptoms and their severity and medicine intake while on the go, multiple times per day. The self-tracker sends the data to an accompanying smartphone application to support patients in understanding their illness, be used in doctors’ consultation, and collect data for allergy research. We chose natural leather as a material for this domestic medical device due to its associations with everyday artifacts, so it would be easier to integrate it into allergy patients’ everyday lives.
