CLARAi (clinical augmented reality and artificial intelligence) is a experimental tool developed by the University of Michigan to measure and to show “pain level” as objectively as possible. It uses Microsoft HoloLens AR glasses to help physicians to visualize pain “on the head” of patient! Another great advantage of CLARAi is to possibility to transport it easily. It allows to use it almost everywhere.
Red and blue dots were used to denote location and level of brain activity, and this “pain signature” was mirror-displayed on the HoloLens AR screen, in order to gauge the cortical activity during evoked acute clinical pain. They found that 3-layer NN achieved optimal classification accuracy (80.37%) for pain discrimination. The study was published on May 12, 2019, in the Journal of Medical Internet Research.
