A pointing device with independently movable portions is described. In an embodiment, a pointing device comprises a base unit and a satellite portion. The base unit is arranged to be located under a palm of a user's hand and be movable over a supporting surface. The satellite portion is arranged to be located under a digit of the user's hand and be independently movable over the supporting surface relative to the base unit. In embodiments, data from at least one sensing device is read, and movement of both the base unit and the independently movable satellite portion of the pointing device is calculated from the data. The movement of the base unit and the satellite portion is analyzed to detect a user gesture.

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.

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.

A modular development platform is described which enables creation of reliable, compact, physically robust and power efficient embedded device prototypes. The platform consists of a base module which holds the processor and one or more peripheral modules each having a peripheral device and an interface element. The modules can be electrically and physically connected together. The base module communicates with peripheral modules using packets of data with an addressing portion which identifies the peripheral module that is the intended recipient of the data packet.

A touch panel is described which uses at least one infrared source and an array of infrared sensors to detect objects which are in contact with, or close to, the touchable surface of the panel. The panel may be operated in both reflective and shadow modes, in arbirary per-pixel combinations which change over time. For example, if the level of ambient infrared is detected and if that level exceeds a threshold, shadow mode is used for detection of touch events over some or all of the display. If the threshold is not exceeded, reflective mode is used to detect touch events. The touch panel includes an infrared source and an array of infrared sensors.

A touch panel is arranged to enable communication using infrared signals with nearby devices. The touch panel includes an array of infrared sensors, arranged parallel to the touchable surface of the panel and at least one of the sensors is capable of detecting an infrared signal received from a nearby device.

Augmented reality with direct user interaction is described. In one example, an augmented reality system comprises a user-interaction region, a camera that captures images of an object in the user-interaction region, and a partially transparent display device which combines a virtual environment with a view of the user-interaction region, so that both are visible at the same time to a user. A processor receives the images, tracks the object's movement, calculates a corresponding movement within the virtual environment, and updates the virtual environment based on the corresponding movement. In another example, a method of direct interaction in an augmented reality system comprises generating a virtual representation of the object having the corresponding movement, and updating the virtual environment so that the virtual representation interacts with virtual objects in the virtual environment. From the user's perspective, the object directly interacts with the virtual objects.

Aspects relate to detecting gestures that relate to a desired action, wherein the detected gestures are common across users and/or devices within a surface computing environment. Inferred intentions and goals based on context, history, affordances, and objects are employed to interpret gestures. Where there is uncertainty in intention of the gestures for a single device or across multiple devices, independent or coordinated communication of uncertainty or engagement of users through signaling and/or information gathering can occur.

A user input device is described. In an embodiment the user input device is hand held and comprises a sensing strip to detect one-dimensional motion of a user's finger or thumb along the sensing strip and to detect position of a user's finger or thumb on the sensing strip. In an embodiment the sensed data is used for cursor movement and/or text input at a master device. In an example the user input device has an orientation sensor and orientation of the device influences orientation of a cursor. For example, a user may move the cursor in a straight line in the pointing direction of the cursor by sliding a finger or thumb along the sensing strip. In an example, an alphabetical scale is displayed and a user is able to zoom into the scale and select letters for text input using the sensing strip.

Speckle sensing for motion tracking is described, for example, to track a user's finger or head in an environment to control a graphical user interface, to track a hand-held device, to track digits of a hand for gesture-based control, and to track 3D motion of other objects or parts of objects in a real-world environment. In various examples a stream of images of a speckle pattern from at least one coherent light source illuminating the object, or which is generated by a light source at the object to be tracked, is used to compute an estimate of 3D position of the object. In various examples the estimate is transformed using information about position and/or orientation of the object from another source. In various examples the other source is a time of flight system, a structured light system, a stereo system, a sensor at the object, or other sources.
