Applying user-centered design and the Pi-CON methodology for vital signs sensor development.

Area of Science:

• Biomedical Engineering
• Health Informatics
• Sensor Technology

Background:

• Remote patient monitoring (RPM) offers benefits like cost reduction and fewer infections, but faces usability challenges with unsupervised medical devices.
• Existing RPM solutions often require direct patient interaction or sensor attachment, hindering user experience.

Purpose of the Study:

• To develop a novel sensor system using the Pi-CON (passive, continuous, non-contact) methodology for remote vital sign acquisition.
• To enhance patient and caregiver user experience by minimizing device interaction and eliminating the need for physical sensor attachment.

Main Methods:

• Application of the Pi-CON methodology for sensor development.
• Integration of radar and optical sensing technologies for vital sign acquisition.
• Development of a cloud-based service with an intuitive user interface for real-time data viewing.
• Adherence to a user-centered design process for both the sensor and interface.

Main Results:

• A novel passive, continuous, and non-contact sensor system for vital sign monitoring was successfully developed.
• The system utilizes radar and optical sensing, transmitting data to a cloud platform.
• An intuitive user interface was created, facilitating remote, real-time data access for patients and caregivers.

Conclusions:

• The developed sensor system addresses usability challenges in RPM by offering a non-contact, low-interaction solution.
• This user-centered approach enhances the potential for effective remote patient monitoring.
• Future work can build upon this technology for broader telehealth applications.
