1. A workstation including a height-adjustable work surface, the workstation comprising:
a frame;
a lift assembly operable to assist translation of the height-adjustable work surface relative to the frame to vary a height of the height-adjustable work surface;
a sensor configured to generate a first signal indicative of translation of the height-adjustable work surface relative to the frame based on movement of a movable member of the workstation;
a processor in communication with processing circuitry; and
a memory coupled to the processor, the memory including instructions that, when executed by the processor cause the processing circuitry to:
receive the first signal;
determine, using the first signal, a work surface value associated with movement of the movable member;
determine, using the first signal, a work surface travel time; and
generate, using the work surface value and the work surface travel time, a translation representation indicative of the translation of the height-adjustable work surface relative to the frame.
