Abstract: A method and system are provided for visualizing a surgical path for a surgical tool. The method comprises a step of receiving anatomical information about a position of at least one anatomical structure in a region to undergo surgery, geometric information describing the surgical path and at least one safety margin defining a minimal distance between the surgical tool and the anatomical structure. The method further comprises defining a critical segment of the surgical path, in which critical segment a distance to the anatomical structure is smaller than the safety margin. Then a graphical representation of the surgical path is provided, wherein the critical segment is highlighted.

Abstract: A system for inducing a subject to fall to sleep includes a light pattern generator for generating a time varying light pattern in view of the subject. Further, the system includes a breathing rate measuring unit for measuring a breathing frequency of the subject. In addition, the system includes a control unit connected to the breathing rate measuring unit and the light pattern generator, for controlling the light pattern generator such that the generated light pattern has a pattern frequency substantially between the measured breathing frequency and a pre-selected desired frequency.

Abstract: A method and system are provided for visualizing a surgical path (31, 41, 51) for a surgical tool. The method comprises a step of receiving (21) anatomical information (14) about a position of at least one anatomical structure (32, 33, 34, 35) in a region to undergo surgery, geometric information (15) describing the surgical path (31, 41, 51) and at least one safety margin defining a minimal distance between the surgical tool and the anatomical structure (32, 33, 34, 35). The method further comprises defining (23) a critical segment (43, 44, 45) of the surgical path (31, 41, 51), in which critical segment (43, 44, 45) a distance to the anatomical structure (32, 33, 34, 35) is smaller than the safety margin. Then a graphical representation (30, 40, 50) of the surgical path (31, 41, 51) is provided (24), wherein the critical segment (43, 44, 45) is highlighted.

Abstract: 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.

Abstract: The invention relates to a method (100) of controlling a viewing parameter for viewing an image on a display for displaying the image, the method comprising a determining step (110) for determining a view of interest within the image, an identifying step (120) for identifying a field of view within the display, a controlling step (130) for controlling the viewing parameter based on the field of view, and a computing step (140) for computing the image based on the controlled viewing parameter and on the field of view, which field of view comprises the view of interest, wherein the field of view is identified using an eye-tracking system for tracking an eye of a user. The method (100) provides a way of controlling the viewing parameter which reduces interruptions in viewing the view of interest.

Abstract: The invention relates to a system (1) for inducing a subject to fall to sleep, comprising a light pattern generator (3) for generating a time varying light pattern in view of the subject. Further, the system comprises a breathing rate measuring unit (2) for measuring a breathing frequency of the subject. In addition, the system comprises a control unit connected to the breathing rate measuring unit and the light pattern generator, for controlling the light pattern generator (3), such that the generated light pattern has a pattern frequency (13) substantially between the measured breathing frequency (8) and a pre-selected desired frequency (5).

Abstract: The invention relates to a method of providing touchless manipulation of an image through a touchless input device (210), the method comprising selecting a property of a manipulation mode with the image in response to touchless user interaction along a first axis with respect to a plane of a sensing region (206, 208) of the touchless input device, and manipulating the image in response to touchless user interaction along a second axis substantially orthogonal to the first axis according to the selected property of the manipulation mode. The invention further relates to a computer program product, a computer storage medium, a display device and a medical workstation.

Abstract: A method and system for effectively and efficiently constructing a development environment for graphical user interfaces for an electronic consumer product. The basic aim of the invention tool is to automatically generate an interface in the authoring environment for customer specific target control components. This is done so by automatically creating a host platform control component (in the format of an OCX) from an existing target platform control component (in the format of a C header file). After running the invention once for every control component, a designer can then write on the host, for instance Visual Basic application code that performs calls to properties and methods of these generated control components.
