Focusing on a sense of body ownership (SoB) and a sense of agency (SoA), we designed an interaction in which the user's upper limb movements are synchronized with the arm movements of a giant avatar to destroy a building using a wearable force-sensing device. The device combines a magneto-viscous fluid brake and a vibration motor, and is capable of presenting inertial forces and a sense of collision in response to joint acceleration. Experimental results showed that the device improved the sense of weight and the sense of destruction while maintaining the sense of body ownership and the sense of agency.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Virtual reality; Haptic devicesHuman centered computing → Virtual realityHaptic devices10.2312/egve.202513652 pages
