1. A method comprising, by a head-mounted device:
receiving, at the head-mounted device, one or more touch inputs from a user corresponding to an activation trigger for an assistant system executing on the head-mounted device;
accessing, by the head-mounted device, one or more signals from one or more inertial measurement unit (IMU) sensors of the head-mounted device;
determining, by an on-device don/doff detection model and based only on the one or more signals from the one or more IMU sensors, that the user is either donning or doffing the head-mounted device; and
overriding the activation trigger to prevent an activation of the assistant system responsive to the received one or more touch inputs.
