The “up-side” and “down-side” of tactile parameters: An evaluation of increases and decreases in tactile cue magnitude to support anesthesia monitoring

摘要

There is a need to find alternative ways to present information to alleviate data overload in the complexenvironment of anesthesia monitoring in the operating room. The tactile modality has been shown as apromising means in supporting this effort; however, to develop effective tactile displays, it is important toensure that the tactile parameters convey information that is both meaningful and easy to learn. This workaimed to address this gap by evaluating how increasing and decreasing tactile parameter magnitude couldmap to physiological variables to support anesthesia monitoring. It was found that increases in magnitudefor the intensity and temporal parameters mapped to urgent changes in physiological variables whereasdecreases in magnitude for these parameters mapped to less urgent changes (e.g., a physiological variable isnormalizing). This work provides preliminary support towards a better understanding of which tactileparameters should be used to represent information in the operating room to support anesthesia monitoring.Furthermore, it demonstrates how increases and decreases in tactile parameters can be interpreteddifferently, emphasizing the importance of carefully considering how to utilize changes in tactileparameters to convey information in complex domains.
