Although the value of video registration is recognized, medicolegal concerns regarding the privacy of patients and professionals are growing. A clear understanding of the legal framework is lacking. Therefore, this research aims to provide insight into the juridical position of patients and professionals regarding video recording in health care practice. Methods: Jurisprudence was searched to exemplify legislation on video recording in health care. In addition, legislation was translated for different applications of video in health care found in the literature. Results: Three principles in Western law are relevant for video recording in health care practice: (1) regulations on privacy regarding personal data, which apply to the gathering and processing of video data in health care settings; (2) the patient record, in which video data can be stored; and (3) professional secrecy, which protects the privacy of patients including video data. Practical implementation of these principles in video recording in health care does not exist. Conclusion: Practical regulations on video recording in health care for different specifically defined purposes are needed. Innovations in video capture technology that enable video data to be made anonymous automatically can contribute to protection for the privacy of all the people involved. http://repub.eur.nl/res/pub/13337/ 2004-07-01T00:00:00Z Previous research has shown that humans generalize distortions of visuomotor feedback in terms of egocentric rotations. We examined whether these rotations are linked to the orientation of the eyes or of the shoulder of the arm that was used. Subjects moved a hand-held cube between target locations in a sequence of adaptation and test phases. During adaptation phases, subjects received either veridical or distorted visual feedback about the location of the cube. The distortions were changes in azimuth either relative to the eyes or to the shoulder. During test phases subjects received no visual feedback. Test phases were performed either with the arm that was exposed to the distorted feedback or with the unexposed arm. We compared test movement endpoints after distorted feedback with ones after veridical feedback. For the exposed arm, the spatial layout of the changes in endpoints clearly reflected the small differences between a rotation around the shoulder and around the eyes. For the unexposed arm, the changes in endpoints were smaller for both types of distortions and were less consistent with the distortions. Thus although the adaptation closely matches the imposed distortion, it does not appear to be directly linked to the orientation of the eyes or of the exposed arm. http://repub.eur.nl/res/pub/1099/ 2003-03-14T00:00:00Z We investigated the human ability to align visually and kinaesthetically perceived end positions of arm movements. We specifically looked at the spatial characteristics of movement endpoints and the responses of the visuomotor system to altered relationships between visual and kinaesthetic information. In these studies we tried to determine what spatial information is incorporated in the motor commands generated by the visuomotor system and how this spatial information is represented. The tasks and experimental setup in the present studies were designed to study three-dimensional arm movements with the above-mentioned factors in mind. The main aim of the present research was to reveal the nature of visuomotor coordination. However, the paradigm used also serves to assess the adaptability of the visuomotor system. This may have implications for ’real-life’ situations in which humans are confronted with discrepant sensory information. Discrepancies between what we feel and what we see are present in nearly all man-machine interactions, for instance, in teleoperation. Depending on the circumstances and the task at hand this may impose major demands on the operator and may lead to serious accidents. Endoscopic surgery is seen as complicated and difficult to learn. Knowledge about the way the visuomotor system is organised and the processes by which adaptation occurs may help to identify the crucial difficulties encountered when using complex tools and contribute to the development of appropriate training programs.
