    摘要： Teachings herein compose a digital image so that the image is perceptible on a viewing surface, such as a projection surface or a transparent screen. In doing so, the teachings advantageously recognize a digital image as consisting of one or more logical objects, like buttons of a user interface. Often, logical objects may be spatially arranged within the image and/or colored in different possible ways without substantially affecting the meaning conveyed by the image. Exploiting this, teachings herein evaluate light reflected from, or transmitted through, the viewing surface, and compose the digital image from one or more logical objects that have a spatial arrangement or coloration determined in dependence on that evaluation. The teachings might, for example, place a logical object within the image so that it will be displayed on a region of the surface which has high contrast with the object's colors and/or low color variance.

    摘要： A method for facilitating anonymous audio and video communication between at least a first user using a first web browser and at least a second user using a second web browser via a server, and a web based system configured to implement the method, is provided. The method comprises browsing to the server using the first web browser, establishing a signalling channel on the server and creating a first unique identifier for the signalling channel. The first unique identifier may be at least temporarily stored at the server. The first unique identifier is transferred to the second user. The method further comprises browsing to the first unique identifier using the second web browser, whereby an anonymous connection is established between the first web browser and the second web browser.

    摘要： Teachings herein prepare a digital image for display on a substantially transparent screen. The teachings advantageously recognize that the perceptibility of the digital image on the screen will often depend on what is visible to a user through the screen, since that will effectively serve as the background of the screen. A method of preparing a digital image thus includes dynamically calculating which part of an environmental background is visible to a user through the screen and thereby serves as an effective background of the screen. This calculation may entail obtaining an image of the environmental background and identifying which part of that image serves as the effective background (e.g., based on the angle at which the user views the screen). The method further includes composing the digital image for perceptibility as viewed against that effective background and outputting the composed image as digital data for display on the screen.

    摘要： A parallel processor (10) having a plurality of parallel computational lanes (L 0 -L 7 ). The parallel processor (10) comprises a data-vector generation unit (40). The data-vector generation unit comprises a first input port (50) for receiving a first vector of data elements from a memory unit (30) and a second input port (60) for receiving a control vector. The data-vector generation unit further comprises an output port (70) for outputting a second vector of data elements to the plurality of parallel computational lanes (L 0 -L 7 ). The second vector comprises more data elements than the first vector. The data-vector generation unit (40) is adapted to generate the data elements of the second vector based on the data elements of the first vector and the control vector. A method of operating the parallel processor (10) is also disclosed.
