Abstract: A terminal device (TD) coupled to a multimedia distribution system (MDS). The terminal device is provided with an interface (IM) having selection buttons associated to sensors (SNS) for allowing a user not only to select multimedia outputs from the multimedia distribution system (MDS), but also for transmitting zapping intentions corresponding to the behavior of the user to a user behavior analyzing device build into the terminal device. The zapping intentions are derived from biometric parameters such as pressure, movement, temperature, heartbeat and/or sweat and are translated by the user behavior analyzing device into behavior parameters that are transmitted to and interpreted by the multimedia distribution system. As feedback, the multimedia distribution system replies with second multimedia outputs with the purpose of orienting or influencing the user in his/her selection choice.
