Title: PREventive Care Infrastructure Based On Ubiquitous Sensing (PRECIOUS)
Brief Summary: The goal of the MI field test is to assess users' overall satisfaction, usability and acceptability of the PRECIOUS system, and to explore if MI in combination with gamification principles is a feasible solution to foster adherence to PRECIOUS system. Moreover, it is pursued to trigger behavior change and build up motivation to maintain sustained change towards healthy lifestyles. The field test at University Hospital Vall d'Hebron will be carried out with morbidly obese pre-diabetic patients. This pilot test will serve to explore users' acceptance of PRECIOUS system in an early stage of its development. Considering that this is a pilot test, feedback and outcomes obtained will serve to refine and adjust PRECIOUS system concept and architecture.
