Abstract : This work investigated the advantages of multi-modality in display capacity for various soldier-critical tasks such as visual search for threat detection. Experiments were conducted at differing sites using individuals of differing skill level. Experimental findings confirmed the multi-modal advantage of joint signal presentation and ascertained that such a multi-modal advantage is found predominantly in the perceptual and decision-making phases of information processing as opposed to purely the motor element. Further, we established that improvements in processing speed were due to concurrent tactile stimulation while improvements in processing accuracy were due to auditory augmented cues, when both were used in conjunction with a visual search task for threat evaluation. These latter advantages occur and thus represent important practical performance gains. This series of experiments have resulted in numerous publications in the open literature and the operationally relevant aspects of these forms of basic investigation have already been usefully deployed.
