Abstract: A portable device (100) comprising a controller (210), a memory (240), a camera (160) and a passive proximity sensor (170). The controller being configured for receiving input from said passive proximity sensor (170) indicating a light environment in front of the passive proximity sensor (170) detecting a change in light environment, determining a light pattern (P) of changes in light environment, determining if the light pattern (P) matches a stored initiating pattern, which is stored in the memory (240), and if so, accepting the light pattern (P) and in response thereto activating the camera (160), identifying an object (H) in front of the camera (160) and tracking the object (H) thereby enabling touchless gesture control of the portable device (100), characterized in that the passive proximity sensor is an ambient light sensor and the light pattern consists of a series of changes between dark and light (dark is light below a threshold, light is light above a second threshold).

Abstract: A computing device (100, 200) comprising a display (120) and a controller (210), wherein said controller (210) is configured to detect and track an object (H) via a video stream (265) provided by a camera (160, 260), detect a movement (G1, G2) of the object (H), translate said movement (G1, G2) of the object (H) to a resulting movement (M1, M2) of a marker (136) based on a scale, detect a change in distance to the object (H), and adapt said scale accordingly.

Abstract: The present invention relates to mechanisms for sharing media items connected to an event between user accounts. An event for media items is created where the event is associated with a context. The created event is associated with a user account. The created event is shared with at least one further user account. The user account and the at least one further user account are associated with a specified subset of user accounts from at least one group of user accounts. Captured media items are connected to the created event. The captured media items are associated with the user account or the at least one further user account. The user account and the at least one further user are provided access to the connected media items. The connected media items are thereby enabled to be shared amongst the user account and the at least one further user account.
