Portable device
A portable device, e.g. a laptop, includes a first part ( 110 ), e.g. a base element, and a second part ( 120 ), e.g. a lid element. The second part ( 120 ) contains an optical remote sensing system ( 300 ). The second part ( 120 ) is pivotably attached to the first part ( 110 ) via a hinge means ( 115 ), such that the portable device may be arranged in an open and a closed position respectively. The optical remote sensing system ( 300 ) is configured to track at least one distinctive feature of a user of the portable device when arranged in the open position. The first and second parts ( 110; 120 ) have a respective essentially flat inner surface ( 111; 121 ), which when the portable device is arranged in the closed position are parallel and face one another. The first part ( 110 ) further includes a recess ( 112 a ) which is arranged relative to a position of the optical remote sensing system ( 300 ) such that, in the closed position, the optical remote sensing system ( 300 ) is at least partly contained in the recess ( 112 a ).
