Beyond Motion Primitives: Behavioral Activity Recognition from Head-Mounted IMU

ArXi:2605.27464v1 Announce Type: cross AR smart glasses need continuous behavioral context to offer proactive assistance, yet their most practical always-on sensor, the head-mounted Inertial Measurement Unit (IMU), detects only motion primitives such as walking or standing. We push beyond motion primitives to behavioral-level recognition, defining five categories that balance AR application need with sensor observability.
