The document discusses research and development work packages for a project. It describes work being done on sensor developments, signal processing algorithms, and user interfaces for biosignal recording and monitoring COPD patients. It outlines two work packages - WP1 focuses on system design, sensor hardware development, and clinical trials, while WP4 analyzes physical and cognitive capacity of COPD patients and evaluates user acceptance. It also discusses the development of user devices to record biosignals with an ergonomic and wireless design, and usability testing of the base station interface with elderly COPD patients at nursing homes and senior centers.
