摘要： The light communication solution presented herein uses waveguides with multiple entrances to efficiently collect light used for light communications and propagate that collected light to a sensor. To that end each waveguide entrance, or at least all but the initial waveguide entrance, is configured to not only collect and input the light into the TIR waveguide, but also to maintain TIR of light already propagating within the TIR waveguide. In so doing, the solution presented herein increases the amount of light available for light communications. Further, because each waveguide may channel light from multiple collection points to a single sensor, the solution presented herein reduces the number of sensors needed for the light communications. The solution presented herein facilitates the implementation of light communications for a wide variety of devices (e.g., cellular telephones, tablets, smartphones, smart watches, smart glasses, etc.) and/or in a wide variety of scenarios.

摘要： There is provided an image acquisition controller for acquiring an adapted image. The image acquisition controller comprises an interface towards a first image sensor, the first image sensor being arranged to acquire an image, and an interface towards a gaze tracking unit, the gaze tracking unit comprising a second image sensor for registering a gaze position on a scene associated with the image acquired by the first image sensor. The image acquisition controller is arranged to periodically receive information over the interface towards the gaze tracking unit about at least a position on the scene associated with the image provided from the first image sensor where the scene represents a larger part of an image registered by the first image sensor than intended to be acquired as the adapted image. The image acquisition controller is arranged to provide information over the interface towards the first image sensor about a position on the first image sensor, a size of a sensor area associated with the position on the first image sensor and a frame rate for image acquisition within said area. The image acquisition controller is arranged to receive image data over the interface towards the first image sensor wherein the image data at least comprises image data with the size, the position on the first image sensor, and the frame rate for image acquisition within said area such that the received image data is stored. An image acquisition system or device comprising the controller, a communication device with corresponding image acquisition capabilities, a method of image acquisition, and a computer program for implementing the method are also disclosed.

摘要： A viewing device comprising a controller, a transparent display and a visual shutter. The controller is configured to determine a color of virtual content to be displayed; determine a background color contrasting the virtual content displayed; determine a display area corresponding to where the virtual content is to be displayed; cause the visual shutter to enable a background to the virtual content to be displayed, the background having the contrasting background color thereby providing a contrasting background to the displayed virtual content (DVC); and to cause the transparent display to display virtual content for overlapping at least one visual object (VO) perceivable through the transparent display at least partially onto the background. The visual shutter is configured to enable the background by operating in a mode wherein at least a portion of the visual shutter is blocked to obstruct the VO in the blocked portion of the visual shutter.
