This work explores a rather intriguing sensory illusion that can extend the sense of touch beyond the confines of your own body.
For a highly accessible discussion, please see the Scientific American Observations write-up of our work (“If (Virtual) Reality Feels Almost Right, It’s Exactly Wrong“).
And for a proper scientific write-up and analysis, see our Science Robotics cover article, The uncanny valley of haptics. Note the main article is short (per the format favored by Science) but the supplementary materials go into considerable depth. The full data, materials, and Azure notebook for the analysis are available as well.
nature materials also featured this work (“Zombie Materials“) but alas their article is paywalled.
