Abstract
Purpose: In two studies examined were the needs of patients regarding the electronic olfactory sensor, and one potential use of prototypic device. Participants with olfactory disorders provided information on situations that are most impaired due to olfactory disfunction, and their expectations of the sensor. Prototypic smartwatch that knows by smell (KnowsWatch) was trained to distinguish spoiled meat and fish from the fresh, and achieved good accuracy in laboratory environment. Methods: Participants with olfactory disorders completed a questionnaire regarding impaired situations and sensor expectations. Their needs were then answered with proper training of the KnowsWatch – electronic nose in a form of a smartwatch. Results: Around half of the participants expressed interest in using KnowsWatch in their daily lives. Most prevalent mentions of desired functions were detection of smoke and gas, recognition of spoiled food, and personal hygiene. KnowsWatch was trained to recognize spoiled and fresh meat and fish and achieved very good accuracy in the laboratory environment. Conclusion: As participants with olfactory disorders express the need of assistance in some olfactory-related daily situations, the KnowsWatch could be good answer to their queries. Prototypic device answers some of mentioned expectations and proved to be efficient in laboratory testing. It is now time to test in in real-life situations.
