Emulating fluid behavior for virtual environments

A system comprising:

• processing circuitry;
• and
• non-transitory computer-readable media storing instructions that, when executed by the processing circuitry, cause the processing circuitry to:
• obtain position tracking data corresponding to a physical vessel equipped with a plurality of vibrotactile actuators arranged along an interior surface of the physical vessel;
• output a virtual environment for display to a display interface, wherein the virtual environment includes a virtual container representing the physical vessel and a virtual fluid inside the virtual container;
• detect, based on the position tracking data, that a user interaction with the physical vessel satisfies an acceleration threshold;
• and
• in response to detecting that the user interaction with the physical vessel satisfies the acceleration threshold, provide haptic output from the plurality of vibrotactile actuators, wherein to provide the haptic output, the processing circuitry is further configured to:
• calculate a motion of the virtual fluid within the virtual container using the user interaction detected with the physical vessel;
• update the virtual environment to display a relative position of the virtual fluid based on the motion;
• calculate a center of gravity of the virtual fluid based on the motion;
• and
• activate one or more of the plurality of vibrotactile actuators of the physical vessel based on the calculated center of gravity.
