摘要： The invention relates to techniques for speckle reduction in holographic optical systems, in particular holographic image display systems. We describe a holographic image display system for displaying an image holographically on a display surface, the system including: a spatial light modulator (SLM) to display a hologram; a light source to illuminate said displayed hologram; projection optics to project light from said illuminated displayed hologram onto said display surface to form a holographically generated two-dimensional image, said projection optics being configured to form, at an intermediate image surface, an intermediate two-dimensional image corresponding to said holographically generated image; a diffuser located at said intermediate image surface; and an actuator mechanically coupled to said diffuser to, in operation, move said diffuser to randomise phases over pixels of said intermediate image to reduce speckle in an image displayed by the system.

摘要： We describe a touch sensing system comprising a light source to project light defining a touch sheet above a surface; a camera directed to capture a touch sense image from the touch sheet, comprising light scattered by an object; and a signal processor to process the touch sense image to identify a lateral location of the object on the surface. A brightness of the projected light is modulated to define bright, touch detecting intervals and dark intervals. The camera and the light projection are synchronized such that the camera selectively captures scattered light during the touch detecting intervals and rejects ambient light during the dark intervals. The system further comprises a pen. The pen comprises a photodetector to detect the projected light, a first light source detectable by the camera, and a controller coupled to control the first light source such that it is selectively illuminated during touch detecting intervals in synchronism with modulated projected light of the touch sheet.

摘要： We describe a touch sensitive image display device for projecting a touch sensitive displayed image at an acute angle onto a surface on which the device is placed. The device comprises: light sources to project two-dimensional first and second light distributions in respective first and second planes; and a multi-pixel sensor system to remotely detect touch of an area of said surface within or adjacent to the displayed image by detecting light from the first distribution to provide a detected touch signal. The multi-pixel sensor system also remotely detects presence of an object within the second light distribution to provide a detected presence signal. The device is configured to multiplex projection of the first light and second distributions. A controller has an input to receive the detected touch and detected presence signals and is configured to control the device responsive to these signals.

摘要： A method of distributed authorization of one or more client applications to one or more connected devices. The method comprises: receiving at a connected device, from a browser executing a client application, a client token and an access request. The client token has been provided to the client application by a process comprising generating one or more client tokens, one for each of one or more client applications (a client token defines permissions for a client application and a domain hosting the client application); signing the client tokens with a private key of a client token issuer, and distributing the client tokens to the client applications; verifying a signature of the client token using a public key of the client token issuer; determining whether the client token grants the client application permission for the access request and, if permission is granted: replying to the browser with a redirect response including an access token granting permission for the client application to access the connected device and identification of the domain hosting the client application from the client token; and executing the redirect response with the browser to make the access token available to the client application for use by the client application when requesting the connected device to perform a task.

摘要： We describe a method of capturing writing or drawing on a whiteboard. The method comprises: inputting camera data for a succession of image frames, wherein the camera data is from a camera directed towards the whiteboard and the image frames comprise successive images of the whiteboard from the camera; and user filter processing data from said image frames to remove parts of said image frames corresponding to parts of a user or user pen writing or drawing on said whiteboard. The user-filter processing comprises filtering to distinguish between motion of the user/user pen parts in the image frames and writing/drawing image information in the image frames which appears or changes during said writing or drawing but which is thereafter substantially unchanging. The method outputs writing/drawing data from the user filter-processing, this defining captured writing or drawing from the whiteboard.
