Overview
Weight perception is a fundamental part of interacting with real-world objects, and incorporating it into VR can significantly enhance immersion—imagine truly feeling the heaviness of an apple or a glass of water in a virtual scene. However, delivering weight sensations in a lightweight form factor remains a persistent challenge.


We introduce an electrotactile weight simulation method that enhances weight perception by inducing a slip illusion. When the user applies insufficient force, the system delivers a specific electrotactile pattern to create a slipping sensation, prompting the user to subconsciously tighten their grip and thereby perceive the virtual object as heavier. Multiple user studies have shown that this method reliably elicits the slip illusion and substantially enhances perceived weight in VR.
