Abstract: A method for the broadcasting by a watch of an informative message relating to an evaluation of the quality of life of a wearer of the watch includes the following steps: recording, by the processing unit, of data describing at least one factual episode of at least one type of environmental event recorded during a given period; identifying at least one type of environmental event disturbing the quality of life of the wearer from processing of the descriptive data; estimating an evaluation index of the quality of life of the wearer according to an indicator of disturbance of the quality of life relating to each type of environmental event disturbing the quality of life identified, and design of the informative message including the estimated evaluation index in prediction of its broadcasting to the wearer.

Abstract: A method transmits by a watch an information message relating to an assessment of the sleep quality of a user of the watch. The method includes the following steps: recording by the processing unit of data describing at least one event-driven episode of at least one type of environmental event recorded during a sleep period of the user; identifying at least one type of environmental event that disturbs the user's sleep by processing the descriptive data; estimating a sleep quality assessment index for the user as a function of a sleep disturbance indicator for each identified type of sleep disturbing environmental event, and devising an information message including the estimated assessment index for the purpose of diffusion to the user.
