Claim 19:
20. An artificial reality system comprising:
a head-mounted display dimensioned to be worn by a user of the artificial reality system; and
a haptic feedback system communicatively coupled to the head-mounted display, wherein the haptic feedback system comprises:
an actuator;
a supply valve coupled to the actuator;
an exhaust valve; and
a fluidic mass controller communicatively coupled to the supply valve and the exhaust valve, wherein the fluidic mass controller implements a machine learning model that facilitates:
placing the exhaust valve in a state that prevents a fluid from escaping the actuator;
activating the supply valve to fill the actuator with the fluid;
determining that the actuator has filled with a certain amount of the fluid based at least in part on at least one electrical signal received from an electronic pressure sensor; and
in response to determining that the actuator has filled with the certain amount of the fluid, deactivating the supply valve to trap the certain amount of the fluid in the actuator.
