To evaluate the idea of a multifunctional mobile pen computer to support information processing tasks of health care professionals we carried out a field study. On a tablet-sized mobile pen computer we set up a health professional workstation, MEDIAS/WIN, with most of the application systems that are presently used by health professionals at Heidelberg University Medical Center. Our experiences during the study, involving 11 physicians, nine nurses and four computer scientists showed that it's not enough to make existing applications mobile most user interfaces have to be adapted for pen input. The presented system served as a valuable basis for study purposes but was not suitable for use in clinical routine. Patient data of the current clinical case and medical knowledge in the form of reference lists were found to be most important for mobile usage. Desirable functionality also included mobile access to electronic mail, electronic ordering of meals and some documentation tasks, e.g. the documentation of diagnoses and orders for diagnostic and therapy.
Physical exposure to risks for potential work-related musculoskeletal injuries has been assessed using a variety of methods, including pen and paper based observation methods, videotaping and computer-aided analysis, direct or instrumental techniques, and various approaches to self-report assessment. These methods are critically reviewed in this paper. The applications of these techniques in ergonomic and epidemiologic studies are considered, and their advantages and shortcomings are highlighted. Finally, a strategy that considers both the ergonomics experts' view and the practitioners' needs for developing a practical exposure assessment tool is then discussed.
The objective of this study was to examine the effects of optical and tracking properties on the accuracy of an optically locatable operating microscope. The intraoperative arrangement was based on experimental results obtained from a skull model. Measurements were taken from 24 patients undergoing intranasal microscopic sinus surgery for various disorders. Two major groups of influencing factors were determined from measurements on the model: 1) optical properties of the microscope, such as the method of focal point adjustment, focal length, and magnification of the lens; and 2) tracking properties of the microscope, such as the distance of the digitizer to the tracked object, the number of reference infrared light-emitting diodes (IR-LEDs), and the area circumscribed by these IR-LEDs. Patient measurements showed an overall spatial error of 2.39+/-1.15 mm with a laser-supported adjustment of the focal point of the microscope. Although the associated 95th percentile was at 4.36 mm, such a value is encouraging for further development of microscopically navigable systems. It must be noted that the noninvasive patient-to-image registration was performed on the basis of a computed tomographic image with a slice distance of 2 mm.
