Methods, systems, and apparatuses for combining pressure measurement with a dynamic system model to estimate the air mass within an actuator, and then estimate the applied contact force which may be based on a quasi-static deformation model.

Estimation or control of contact force in actuators using pressure

The present concepts relate to devices that can employ graspable controllers that can be employed in various scenarios, such as virtual reality scenarios and augmented reality scenarios. One example device can include multiple expansion assemblies having independently adjustable girths. The multiple expansion assemblies can be stacked adjacent to one another along an axis. A controller can be configured to expand or contract the girths of the expansion assemblies to collectively approximate girths of an object.
