OlfaCare: A Portable Testing and Rehabilitation Assistance Service Designed for Groups with Olfactory Dysfunction

Olfactory dysfunction, including conditions such as anosmia, affects a significant portion of the population, particularly the elderly. It can substantially impair daily activities, including the ability to detect hazardous situations such as gas leaks, and diminish the enjoyment of food, ultimately affecting individuals' quality of life. Despite the high prevalence of olfactory disorders, existing at-home testing and rehabilitation solutions are often cumbersome and lack sufficient user engagement.The Olfacare system aims to bridge these gaps by providing a comprehensive, user-friendly solution for olfactory dysfunction. The proposed system consists of three main components: a portable olfactory test kit, an olfactory recovery kit, and a mobile application. The portable test kit enables users to self-assess their olfactory abilities at home using a series of standardized odour samples. The recovery kit, tailored for individuals with olfactory dysfunction, provides clinically proven odour-based stimuli for training, supporting personalised rehabilitation. The mobile application serves as the core platform for the system, guiding users through the testing and rehabilitation process, recording data, offering real-time feedback and supervision. Key features of the app include olfactory testing and training sessions, progress tracking and rehabilitation reminders.Through this approach, Olfacare addresses the major challenges faced by individuals with olfactory dysfunction, such as limited access to professional services and difficulties maintaining at-home rehabilitation routines. The system is designed to enhance user autonomy by offering a seamless, engaging experience that encourages sustained participation in olfactory training. This research represents an important step toward improving the daily lives of those affected by olfactory disorders, promoting independence, and reducing reliance on healthcare providers. Future evaluations and user feedback will further refine the system’s effectiveness and usability.
