A system for exerting forces on a user. The system includes a user-mounted device having one or more masses disposed along one or more tracks. The system further includes a processor configured to generate a first actuator control signal to configure a first actuator to move a first mass included in the one or more masses at a first acceleration in a first direction along a first track included in the one or more tracks. The processor is further configured to generate a second actuator control signal to configure at least one of the first actuator and a second actuator to move the first mass at a second acceleration in the first direction along the first track. A magnitude of the first acceleration is above a threshold acceleration, and a magnitude of the second acceleration is below the threshold acceleration.
