    摘要: A tabletop display providing multiple views to users is described. In an embodiment the display comprises a rotatable view-angle restrictive filter and a display system. The display system displays a sequence of images synchronized with the rotation of the filter to provide multiple views according to viewing angle. These multiple views provide a user with a 3D display or with personalized content which is not visible to a user at a sufficiently different viewing angle. In some embodiments, the display comprises a diffuser layer on which the sequence of images are displayed. In further embodiments, the diffuser is switchable between a diffuse state when images are displayed and a transparent state when imaging beyond the surface can be performed. The device may form part of a tabletop comprising with a touch-sensitive surface. Detected touch events and images captured through the surface may be used to modify the images being displayed.

    摘要: Touch detection systems and methods are described. The system comprises a light guiding sheet, a light source, a reflective layer and a detector. When a fingertip or other suitable object is pressed against the light guiding sheet, light which is undergoing total internal reflection within the sheet is scattered. The scattered light is reflected by the reflective layer and detected by the detector. In an embodiment, the light is infra-red light. The touch detection system may, in some embodiments, be placed on a display and the touch events used to control the display.

    摘要: A volumetric display system which enables user interaction is described. In an embodiment, the system consists of a volumetric display and an optical system. The volumetric display creates a 3D light field of an object to be displayed and the optical system creates a copy of the 3D light field in a position away from the volumetric display and where a user can interact with the image of the object displayed. In an embodiment, the optical system involves a pair of parabolic mirror portions.

    摘要: Mobile device localization using audio signals is described. In an example, a mobile device is localized by receiving a first audio signal captured by a microphone located at the mobile device and a second audio signal captured from a further microphone. A correlation value between the first audio signal and second audio signal is computed, and this is used to determine whether the mobile device is in proximity to the further microphone. In one example, the mobile device can receive the audio signals from the further microphone and calculate the correlation value. In another example, a server can receive the audio signals from the mobile device and the further microphone and calculate the correlation value. In examples, the further microphone can be a fixed microphone at a predetermined location, or the further microphone can be a microphone located in another mobile device.

    摘要: Ferromagnetic user interfaces are described. In embodiments, user interface devices are described that can detect the location of movement on a user-touchable portion by sensing movement of a ferromagnetic material. In some embodiments sensors are arranged in a two dimensional array, and the user interface device can determine the location of the movement in a plane substantially parallel to the two-dimensional array and the acceleration of movement substantially perpendicular to the two-dimensional array. In other embodiments, user interface devices are described that can cause a raised surface region to be formed on a ferrofluid layer of a user-touchable portion, which is detectable by the touch of a user. Embodiments describe how the raised surface region can be moved on the ferrofluid layer. Embodiments also describe how the raised surface region can be caused to vibrate.

    摘要: A user interface for an information retrieval system is described. In an embodiment an output region for showing retrieved documents is displayed on an interactive surface. One or more movable user interface items, such as digital buttons or tangible objects, may be positioned in an active region. Each movable user interface item has a stored query associated with it and for example, the queries may be words or images. In an embodiment a user interface controller apparatus identifies any movable user interface items in the active region and identifies a spatial relationship between those items and the output region. In an embodiment, a query is accessed for each of the user interface items in the active region and those queries and the information about the spatial relationship are used to retrieve documents from a document database.
