Method for determining a content parameter of video data, in particular a movie or series, at least comprises the steps: displaying a video with a display device (103, 201), in particularly a TV, constantly capturing values representing the heartrate of a user by means of a heart rate sensor of a wearable device (101, 300), in particularly a smartwatch, linking values of the constantly captured heartrate of the user individually with timestamps of the video data, determining if a captured value is above or below a predefined heartrate threshold and detecting movements of the wearable device (101, 300) by means of at least one motion sensor, wherein capturing of physical parameters of the user is paused in case sensor data generated by the sensor represents movements of the user, wherein said movements are walking or running movements, wherein the wearable device comprises the motion sensor displaying a notification by means of the display device (103, 201), wherein the notification is based on average heart rate data linked to at least one specific timestamp and preferably linked to multiple specific timestamps of the video data, wherein the notification is displayed prior to a specific scene of the video data, wherein the specific scene is identified by means of the at least one specific timestamp and blocking the specific scene in case the measured heart rate of the user is above the predefined heartrate threshold and the average heartrate of an average user of the specific scene was above the predefined heartrate threshold. displaying a video with a display device (103, 201), in particularly a TV, constantly capturing values representing the heartrate of a user by means of a heart rate sensor of a wearable device (101, 300), in particularly a smartwatch, linking values of the constantly captured heartrate of the user individually with timestamps of the video data, determining if a captured value is above or below a predefined heartrate threshold and detecting movements of the wearable device (101, 300) by means of at least one motion sensor, wherein capturing of physical parameters of the user is paused in case sensor data generated by the sensor represents movements of the user, wherein said movements are walking or running movements, wherein the wearable device comprises the motion sensor displaying a notification by means of the display device (103, 201), wherein the notification is based on average heart rate data linked to at least one specific timestamp and preferably linked to multiple specific timestamps of the video data, wherein the notification is displayed prior to a specific scene of the video data, wherein the specific scene is identified by means of the at least one specific timestamp and wherein the notification is based on average heart rate data linked to at least one specific timestamp and preferably linked to multiple specific timestamps of the video data, wherein the notification is displayed prior to a specific scene of the video data, wherein the specific scene is identified by means of the at least one specific timestamp blocking the specific scene in case the measured heart rate of the user is above the predefined heartrate threshold and the average heartrate of an average user of the specific scene was above the predefined heartrate threshold.
