Getting the Buzz: What's Next for Tactile Information Delivery?

As a result of continuous technological advances, information delivery is becoming multi-modal and complex. In many professions (e.g., air traffic control, combat operations) an abundance of information is delivered simultaneously over the visual and auditory sensory channels resulting in cognitive overload and leading to performance degradation over time. The Multiple-Resource theory suggests that offloading information from overtaxed sensory modalities to other modalities can reduce workload (Wickens, 2002). If properly implemented, tactile displays – i.e., devices used to present information to the user by stimulating the skin – may be a viable solution in reducing sensory and cognitive overload from the visual and audio channels. Shifting information to the tactile (touch) channel or judicious use of tactile information in conjunction with auditory and/or visual cues can lead to a reduction in cognitive and perceptual overload and an increase in positive performance outcomes. The primary objective of ...
