摘要： The invention relates to a system (100) for automating adjustment or adaptation of devices (141-143) such as light, computer programs and positioning of devices used during patient examination. The patient examination is performed by use of a scanner system where the patient is lying on a bed (102) which can be moved into a scanner zone of the scanner where the scanning can be performed and away from the scanner zone. The automated control is achieved by detecting the position of the bed and using the detected position for adjusting or adapting the state, i.e. the function or working of one or more devices (141-143).

摘要： An apparatus (1) for rotating objects (40) on screens (9) defines a hand axis (20) in response to 3D position information related to the hands (21, 22) of a user and detects a changed orientation of the hand axis (20) with respect to a 3D space and calculates a rotation for the object (40) on the screen (9) in response to said detecting. This way, to rotate the object (40) on the screen (9), an imaginary copy of the object (40) is considered to be inside an imaginary ball (41) held by the user, which imaginary ball (41) is being rotated. The changed orientation of the hand axis (20) comprises changes in angles between the hand axis (20) and the axes (31, 32, 33) of the 3D space. To improve stability in case of each one of said changes being unequal to zero, the apparatus (1) further detects the angles and compares the respective angles with respective thresholds and reduces or weights the respective changes in response to respective comparison results.

摘要： A system has a contactless user-interface for control of the system through pre-determined gestures of a bodily part of the user. The user-interface has a camera and a data processing system. The camera captures video data, representative of the bodily part and of an environment of the bodily part. The data processing system processes the video data. The data processing system determines a current spatial relationship between the bodily part and another bodily part of the user. Only if the spatial relationship matches a pre-determined spatial relationship representative of the pre-determined gesture, the data processing system sets the system into a pre-determined state.

摘要： The invention relates to a system for manipulating images or graphics where the manipulation to be performed are selected or activated using eye-tracking. A number of hotspots are arranged around and bordering a region of interest (ROI), which are each, associated with an image parameter adjustment (e.g. contrast or brightness). An eye-tracking device determines a fixation point of the user and the system automatically performs the associated adjustment whenever the fixation point falls within a hotspot. The close bordering of the hotspots around the ROI allows the user to keep focus on the ROI and only slightly shift his/her gaze to or towards a hotspot for adjusting an image parameter. Thereby, the adjustment can be controlled while still keeping the ROI in focus so that the effect of the adjustment can be followed simultaneously.
