Abstract: A light therapy system (12) for administering a controllable melanopic luminous exposure includes a controllable lighting assembly (16) for use in delivering the desired luminous exposure. The system further includes a visual display means (18) for presenting at the same time a visual output such as a video to the patient. A target melanopic luminous exposure for administration to the patient is received by a controller 24. This target is then adjusted to compensate for an additional melanopic luminous exposure which the visual display means generates in displaying the visual output. A control schedule is then generated for controlling an illuminance of the lighting assembly to deliver over a defined treatment period the adjusted target melanopic luminous exposure. The lighting assembly is then controlled according to the control schedule.

Abstract: The present invention relates to a device for detecting motion of a person. The present invention further relates to a system incorporating the aforementioned device and a corresponding method. The proposed device comprises a projection sweep unit configured to obtain image data comprising depth information corresponding to an image showing the patient and to generate one or more projection images of the patient for different viewpoints, a motion detection unit configured to detect motion of the patient in the one or more projection images and to generate one or more motion detection signals indicating if motion is detected or not in a respective projection image, and an analysis unit configured to detect and localize body movements of one or more body parts of the patient based on one or more combinations of motion detection signals.

Abstract: The present invention relates to a device, system and method for object recognition. To improve reliability and robustness of the recognition, the device comprises an input unit (21) configured to obtain a depth image (40) of a scene, a computation unit (22) that computes, from the depth image, a noise variance map (42) by computing pixel noise variances at object boundaries of one or more objects in the depth image, a depth confidence map (43) by filtering depth values based on their distance to the depth camera, and a motion confidence map (44) by filtering out variances caused by motion of a person in the scene. Further, from the noise variance map, the depth confidence map and the motion confidence map, one or more candidate regions (45) and their confidence in the depth image are computed, and the one or more candidate regions having the highest confidence are selected as final region of interest (41) representing the object to be recognized.

Abstract: The present invention relates to a device, system and method for monitoring a subject. To obtain increased performance at reasonable cost and complexity, the device comprises an input interface (81) configured to obtain image data acquired over time by an imaging unit from a field of view containing at least part of a subject, a monitoring signal determination unit (82) configured to determine a monitoring signal from the obtained image data of the subject, a processing unit (83) configured to evaluate the image data to determine the spatial configuration of the subject with respect to the imaging unit and to generate a feedback signal for providing feedback about the determined spatial configuration, wherein the feedback signal is configured to control a projection unit (9) to indicate through illumination of the field of view if the spatial configuration can be maintained or shall be changed, and an output interface configured to output the feedback signal.
