The objective of this research was to develop and evaluate an advanced alerting technique that uses the auditory sense as well as the visual sense for alerts in the Combat Information Center CIC. For a tactical officer to make critical decisions, time-critical information needs to be highlighted. Auditory icons were developed and an experiment was designed to test the effectiveness of auditory icons for alerting operational personnel. Auditory icons were compared to buzzers and voice alerts. Overall, the results showed that both voice and auditory icons improved detection and discrimination of alerts compared to the buzzer condition currently used in the CIC. The data were analyzed according to subjects with high errors and subjects with low errors. Both voice and auditory icons significantly improved both alert discrimination and detection for those subjects with high errors. In other words, the high error group greatly improved so that both high and low error groups were more uniform. Only voice alerts reduced response time. Communication deception.
