Method and system for emotion-triggered capturing of audio and/or image data

An apparatus for emotion-triggered control of capture of audio or image data by an audio or image capturing device, the apparatus comprising:

• data input circuitry adapted to:
• receive a time-sequential set of data including first physiological data representing a first physiological parameter corresponding to a first person, second physiological data representing a second physiological parameter corresponding to a second person, and voice audio data including a voice of at least one of the first and the second person, and
• a processing unit adapted to:
• analyze the time-sequential set of data to determine whether a set of one or more features obtainable from the time-sequential set of data matches a set of one or more predetermined characteristics being indicative of respective changes of emotional state of the first person and emotional state of the second person being less than a threshold time difference;
• and
• in response to determining that the set of one or more features matches the set of one or more predetermined characteristics, transmit a trigger signal to the audio or image capturing device.
