The influence of various graphical and numeric trend display formats on the detection of simulated changes.

摘要: Integration of a large amount information is important in anaesthesia but there little research to guide the development data displays. Anaesthetists from two hospitals participated five related screen based simulation studies comparing various formats for display historical or 'trend' data. Participants were asked indicate when they first noticed change each displayed variable. Accuracy and latency (i.e. delay) detection changes recorded. Latency was shorter with graphic than numeric display. Increasing number variables reduction y-axis height increased detection. If same points included, no difference between graphical numerical displays There accuracy These results suggest that way trend presented can influence speed changes.
