The ??Preventive Care Infrastructure based On Ubiquitous Sensing? (PRECIOUS) project aims to improve motivation to healthy life by providing the end-users with a lifestyle dashboard. The system collects information about the user from a variety of devices that measure food intake, physical activity, stress levels and sleep patterns. Links between these key lifestyle aspects are important in delivering an overall picture of the users?? health status. Furthermore, the system and its sensors were designed to be user-friendly and to reduce the burden of recording was possible. In the present study we focus on heart rate sensor and compare the acceptability and usability of the various devices candidates to feed the PRECIOUS system. More precisely, smart-watch, chest-belt and 2-points-electrodes have been tested by users from different categories. Here, a sample of 16 participants with cardiovascular disease and 16 healthy participants composed of students, single workers, family units and retired couples used each kind of heart rate sensor during 24 hours. Each device test leads to consult lifestyle reports about stress, sleep and physical activity. During this experimentation, participants completed different acceptability questionnaires. Results interpretation was performed according to the Technological Acceptance Model (Davis et al. 1989) where the acceptability is determined as the relation between the perceived usefulness and the perceived ease of use. Eventually, the findings of this study reveal which sensor is the most acceptable and give insight into how the different devices features influences their respective usability in the daily life.
