summary

A wearable dual-channel skin-stretch device is built to render an “imaginary joint” at the waist, encoding tail bending and torque by superposed angle and force mappings so bilateral waist skin stretches indicate side, bend, and push. A controlled experiment shows participants identify tail angle and applied force without vision and with higher perceptual accuracy and a tighter confusion matrix than vibrotactile feedback. Angle and force can be read out simultaneously, and the extension is reported as more embodied and intuitive.
