Abstract: The present disclosure provides a method of operating a wearable life logging device (2) comprising a data processing unit (9), a camera unit (7), and at least one motion sensor (4, 5). The method comprises selectively operating the device in a take photo state (200), wherein a photo is captured by means of the camera unit (7), and selectively operating the device in a sleep state (300), wherein the camera unit (7) is in a low power mode. The method further comprises causing the device to transition (120, 330, 430) to the take photo state (200) in response to a signal from the motion sensor (4, 5).
