摘要:
A scanning display apparatus (10) is described. The apparatus (10) includes a display (70) operable: (I) to receive driver signals and generate corresponding visual information for presentation on the display (70); and (ii) to sense radiation received at the display (70) and generating corresponding sensing signals corresponding to a region proximate to the display. The apparatus (10) also includes computer hardware (80) coupled to the display (70) for generating the one or more driver signals for the display (70) and for receiving the one or more sensing signals from the display (70), the computer hardware (80) being operable to provide an interactive user interface (ULI) at the display (70). The display (70) comprises an array of pixel devices (150), each such device (150) integrally being operable to emit radiation therefrom or transmit radiation therethrough, and also to sense radiation incident thereupon. Preferably, the pixel devices (150) are implemented in polyLEDs and/or LCD/TFT technologies.

摘要:
An image display including a touch-sensitive display, that creates tactile sensation and movement of an object (3-2) along its surface is provided. Actuators including conductive rods (4-111, 4-112) attached together may be used, such that each rod of the actuator (4-11) may increase or decrease in size when current is applied to that rod to cause the actuator to bend toward a specified direction. Also, an image display that includes ball bearings (1-10) whose rotation is controlled by driving magnets (1-21, 1-22) to cause an object to move is provided. Further, air holes (3-11) tilted in various directions to control object movement by air pressure may be provided. Moreover, rods (3-10) may be moved up or down as activated by driving magnets (2-20). The actuators, rods, ball bearing assemblies, or holes may provide touch sensitivity for the image display.

摘要:
The invention relates to a system (102) for providing biofeedback to a person (104). The system (102) comprises a source (106) for generating a source signal (108) and a transducer (110) for generating a measurement signal (112) in response to a physiological parameter (114) indicative for mental relaxation of the person (104). The system (102) furthermore comprises a filter (116) for variably filtering the source signal via modifying a cut-off frequency in response to the measurement signal (112) and an interface (118) for providing a biofeedback signal (119) to the person on the basis of the source signal as variably filtered by the filter (116).
摘要:
The invention relates to a method and a system for reducing anxiety of patients before and during e.g. MR scanning examinations. The method is based on displaying images on walls (106,107) of the scanner room (100) so that when the patient enters the scanner room, then an image is displayed on a wall visible to the patient, e.g. a wall adjacent to the entry door (103). When the patient is laying on the table (102) of the scanner (101) the projection of images is switched to another wall by reflecting the projected images using e.g. a mirror which is moved into the light rays emitted by an image projector.
