Three experiments explored the effectiveness of continuous auditory displays, or sonifications, for conveying information about a simulated anesthetized patient's respiration. Experiment 1 established an effective respiratory sonification. Experiment 2 showed an effect of expertise in the use of respiratory sonification and revealed that some apparent(More)
BACKGROUND Previous studies have demonstrated the construct validity of virtual reality colonoscopy simulators by showing that they can distinguish between users according to their level of endoscopic experience. Although physical model simulators are known to simulate looping more realistically than these devices, they lack published validation evidence.(More)
We have proposed an extension of Ecological Interface Design (EID) to encompass the design of auditory displays. Our analysis shows that EID can succeed in this task if all stages of Cognitive Work Analysis (CWA) are employed and if an extra " attentional mapping " stage is added, which maps the attentional need of the human operators. A review of auditory(More)
BACKGROUND No useful comparative data exist on the relative realism of commercially available devices for simulating colonoscopy. OBJECTIVES To develop an instrument for quantifying realism and provide the first wide-ranging empiric comparison. DESIGN Repeated measures, observational study. Nineteen experienced colonoscopists completed cases on 4(More)
OBJECTIVE We explore whether ecological interface design (EID) principles can be applied to the design of an auditory display for anesthesia monitoring. BACKGROUND EID examples focus almost exclusively on visual displays. In the anesthesia work environment, however, auditory displays may provide better individual and team awareness of patient state.

BACKGROUND In a full-scale anesthesia simulator study we examined the relative effectiveness of advanced auditory displays for respiratory and blood pressure monitoring and of head-mounted displays (HMDs) as supplements to standard intraoperative monitoring. METHODS Participants were 16 residents and attendings. While performing a reading-based distractor(More)
We examine how Ecological Interface Design (EID) might better bridge the gap from analysis to design by taking different modalities into account. Whereas almost all previous research using EID has focused on visual displays, attempts to extend the use of EID to non-visual modalities have revealed hidden assumptions that need to be made explicit and(More)
We reviewed the use of advanced display technologies for monitoring in anesthesia. Researchers are investigating displays that integrate information and that, in some cases, also deliver the results continuously to the anesthesiologist. Integrated visual displays reveal higher-order properties of patient state and speed in responding to events, but their(More)
OBJECTIVE To describe studies evaluating 3 generations of three-dimensional (3D) displays over the course of 20 years. SUMMARY BACKGROUND DATA Most previous studies have analyzed performance differences during 3D and two-dimensional (2D) laparoscopy without using appropriate controls that equated conditions in all respects except for 3D or 2D viewing.

We examined the effect of no music, classical music or rock music on simulated patient monitoring. Twenty-four non-anaesthetist participants with high or low levels of musical training were trained to monitor visual and auditory displays of patients' vital signs. In nine anaesthesia test scenarios, participants were asked every 50-70 s whether one of five(More)
