摘要:
The invention describes a method of performing a gaze-based interaction between a user (1) and an interactive display system (2) comprising a three-dimensional display area (D) in which a number of physical objects (10, 11, 12, 13, 14, 15, 16) is arranged, and an observation means (3), which method comprises the steps of acquiring a gaze-related output (30) for the user (1) from the observation means (3), determining a momentary gaze category (Go, Gdw, Gbo, Gnr) from a plurality of gaze categories (Go, Gdw, Gbo, Gnr) on the basis of the gaze-related output (30); and continuously generating display area feedback according to the momentary determined gaze category (Go, Gdw, Gbo, Gnr). The invention further describes an interactive display system (2) comprising a three-dimensional display area (D) in which a number of physical objects (10, 11, 12, 13, 14, 15, 16) is arranged, an observation means (3) for acquiring a gaze-related output (30) for a user (1), a gaze category determination unit (22) for determining a momentary gaze category (Go, Gdw, Gbo, Gnr) from a plurality of gaze categories (Go, Gdw, Gbo, Gnr) on the basis of the gaze-related output (30); and a feedback generation unit (25) for continuously generating display area feedback (29) according to the momentary determined gaze category (Go, Gdw, Gbo, Gnr).
摘要:
Simple gestures such as stroking or tapping of a surface (10) can be used to control common functions of electronic systems (16) by positioning one or more sensors (12) on the surface and detecting sounds generated by the interaction with the surface. Signals corresponding to detected sounds are filtered and interpreted either in the system to be controlled or else in the sensors themselves. The direction of movement of a hand (18) stroking the surface can be interpreted as a command to increase or decrease a parameter, such as the sound volume level of a television, for example. Determination of the position of the user's hand is unnecessary. The apparatus is therefore simple, inexpensive, robust and discrete, requiring only a minimum of installation and without being necessarily dedicated to a particular electronic system to be controlled.

The disclosed embodiments relate to functional and decorative lighting. A transparent body (100) comprises a plurality of light guides (130, 140) forming a matrix. Light is emitted from light sources (210, 220). In the cells of the matrix in which light from different light sources (210, 220) intersects, the light is mixed which results in different cells having different colors.

A pawn (10) for use on a board (21) is provided. The pawn (10) is arranged to provide a trigger signal upon a touch of a triggerable part of the pawn (10) by a user, and comprises communication means for communicating the trigger signal to a board (21). The pawn (10) comprises at least two separate triggerable sub-parts (11, 12) for, upon a touch of each respective one of the at least two separate triggerable sub-parts (11, 12) by a user, respectively providing a first and a second trigger signal. The first and the second trigger signal are mutually distinguishable. Such a pawn (10) can easily be used for activating a certain function of a set of functions. A function is selected by touching a corresponding triggerable sub-part (11, 12).
摘要:
Light-based systems for communicating information associated with the formation of social connections are disclosed. One or more lighting controllers controlling individually controllable luminaires are used in conjunction with communication networks in order to identify and form remote light-based social connections. Additionally, visualization controllers are used in conjunction with visualization infrastructures, visualization actuators, localization systems and identification systems to visually identify proximally present potential social connections.

The invention relates to an apparatus for object presentations by means of an electronic display system, such as a shelf with an integrated lighting system for illuminating objects positioned on a surface of the shelf in order to create appealing object presentations for example in shops, museums or homes. A basic idea of this invention is to integrate a display system such as a lighting system into a presentation device for quickly and easily creating a decoration effect such as a light effect for attracting people. The invention provides in an embodiment an apparatus (10) for object presentations comprising a presentation device (12) with a surface (14) to display an object (16) being placed on the surface, and an electronic display system (18) being integrated in the presentation device and adapted to create a decoration effect (20) on the surface. By integrating the display system in the presentation device, on which an object to be presented may be placed, the decoration effect is created from the bottom, i.e. from below the object, and, thus, does not require as much space as a decoration effect from above the object may require.

The present invention relates to a signage system (10) comprising a plurality of textile products (12), wherein each textile product comprises a flexible display device (14) adapted to show a display content forming part of a unified message. The system is characterized in that each flexible display device (14) further is adapted to show an indication of the position of the display content of the flexible display device in relation to the display contents of the other flexible display devices in the unified message, before showing the display content. The present invention also relates to a method for presenting a unified message by means of a plurality of flexible display devices (14) each comprised in a textile product (12).
摘要:
A storage medium for storing digital information is disclosed. The storage medium comprises a label comprising a light addressable electrophoretic ink layer. Further, a method for labeling a storage medium provided with an electrophoretic ink label is disclosed. The method comprises the steps of applying a voltage between a first and a second electrode being arranged on mutual sides of a electrophoretic ink layer; irradiating selected pixel areas of the electrophoretic ink for addressing a change of visual state. Further, a recorder for an optical storage medium and a label writer for labeling an optical storage medium are disclosed. The recorder and the label writer comprise a light source and a charging device. The charging device is arranged to apply an electric field across an electrophoretic ink layer of the storage medium, and the light source is arranged to write a label on said storage medium by addressing pixel areas of said electrophoretic ink layer.
