Persuasive e-coaching framework: test with a reduced number of sensor

Increasingly, persuasive technologies are used to convince, stimulate and motivate users to engage in healthy behaviours. Currently persuasive technologies are based either on social psychology theories (the user compares him/herself with other people), self-determination (human behaviour is a result of a decision that was either taken autonomously or that was rather imposed to a person), goal-setting (process by which people attempt to constrain unwanted urges by gaining control over the impulsive response), or health belief model (individual's perception of the severity, benefit, barrier of a situation or action to perform). However few approaches have tried to integrate user's emotion. In this paper we present a persuasive e-coaching framework which explicitly consider and integrate the emotion in the decision making process. Toward the objective to deploy such solution, the first critical step is to identify a sensor configuration that is accurate enough and minimally invasive. We present the results obtained with only one physiological sensor.
