Eye-tracking reveals how observation chart design features affect the detection of patient deterioration: An experimental study

The features of the expert study of traces from the effects of foreign objects on the inner surfaces of the cylinder mechanisms are considered. With the trasological examination of locks, most experts after examining the external and internal surfaces of the cylinder mechanisms of locks, unlocked by various types of keys, falsified or selected keys, ambiguously understand the mechanism of their trace formation, which can sometimes lead to a false conclusion. The purpose of the work is to present the results of the investigation of the mechanism of trace formation and localization of signs of exposure of foreign objects (lock pick, selected or fake keys) on the internal surfaces of the cylinder mechanisms of locks and recommendations to forensic experts in drawing conclusions during the course of the Trasological research. The mechanism of trace formation is considered, the characteristic and classification of traces of exposure to foreign objects are provided (lock pick, selected or fake keys). Groups of lock pick are identified, which are most often found in the Commission of criminal offenses, for their further research. A number of experimental studies have been carried out to study and analyze the mechanism of trace formation, as well as to localize the signs of influence of certain groups of lock pick on the internal surfaces of the cylinder mechanisms of the lock. The progress of the experimental studies has been described in stages. The results of the research on the opening of the cylinder mechanisms of locks are presented with various types of lock pick, depending on their design features. The illustrations explain the conditions for the location of traces on the relevant parts of the cylinder mechanisms of locks from the influence of the respective groups of lock pick. The results of an experimental study are summarized and conclusions are made on the possible conditions for the mechanism of trace formation. Recommendations to judicial experts on the formulation of conclusions in the course of trasological studies of cylinder locking mechanisms are proposed.

Multiple Patients

Head-worn displays (HWDs) can help clinicians monitor multiple patients by displaying multiple patients’ vital signs. We conducted four experiments exploring design features that affect how a HWD can quickly and reliably cue attention to patient deterioration. In a series of lab-based experiments, we found that a HWD could quickly and reliably cue participants’ attention with high-contrast visual highlights with two distinct levels, or with a short white flash. However, visual alerts on a HWD did not cue attention as quickly as similar alerts on a conventional screen or auditory alerts. We conclude that HWDs can quickly notify clinicians of patient deterioration when paired with a strong visual cue, but there are perceptual challenges unique to HWDs.

Tracking Method

This experimental study ( N = 77) examined the role of infographics in orienting viewer's attention in television news. The results of pupil dilation measurements using the eye-tracking method showed that when used in the over-the-shoulder format, visual representation of numerical data triggers an orienting response and directs the viewer's attention to that part of the screen. The study also showed that bar graphs were more successful in holding viewer's attention than the simple tabular presentation of information, with a significant covariate of video viewer size, and that the presence of infographics and individuals’ quantitative ability both positively predicted information recall.

The Impact

Simulation-based learning is an effective technique for teaching nursing students’ skills and knowledge related to patient deterioration. This study examined students’ acquisition of theoretical knowledge about symptoms, pathophysiology, and nursing actions after implementing an educational intervention during simulation-based learning. A quasi-experimental study compared theoretical knowledge among two groups of students before and after implementation of the intervention. The intervention introduced the following new components to the existing technique: a knowledge test prior to the simulation, video-recording of the performance, and introduction of a structured observation form used by students and facilitator during observation and debriefing. The intervention group had significantly higher scores on a knowledge test conducted after the simulations in comparison to the scores in the control group. In both groups scores were highest on knowledge of symptoms and lowest on knowledge of pathophysiology; the intervention group had significantly higher scores than the control group on both topics. Students’ theoretical knowledge of patient deterioration may be enhanced by improving the students’ prerequisites for learning and by strengthening debriefing after simulation.
