1. A system for navigating a virtual environment using seated walking-in-place footstep locomotion, the system comprising:
a first sensing device configured to sense first footstep locomotion of one of feet of a user seated in a physical environment to generate and transmit a first stepping signal, wherein the first sensing device comprises:
a first main body;
a first sensor arranged in a location where the first main body senses the first footstep locomotion of a first foot of the user in a seating posture and configured to sense the first footstep locomotion to generate the first stepping signal; and
a first controller, arranged on the first main body, connected to the first sensor, and configured to receive and transmit the first stepping signal;
a second sensing device configured to sense second footstep locomotion of another of the feet of the user seated in the physical environment to generate and transmit a second stepping signal; and
a virtual reality device configured to receive the first stepping signal and the second stepping signal and navigate the virtual environment in a virtual locomotion mode according to an order of receiving the first stepping signal and the second stepping signal.
