Exercise machine comprising a user force input element, for example a set of bicycle pedals, a transmission unit, an electric motor, and an electrical circuit connected to the electric motor. The user force input element is connected to the electric motor via the transmission unit such that said electric motor turns at an angular velocity which is different than the velocity or angular velocity of the user force input element and the motor runs as a generator such that when the electric motor is turned, an electrical current is developed in the electrical circuit. The electrical circuit comprises an electrical resistor, a switching element, a Pulse Width Modulation (PWM) controller, and a load reference controller. The electrical resistor is connected to the electric motor via the switching element such that when the switching element is switched on and off, the electrical resistor is electrically connected and disconnected from the electric motor. The switching element is controlled via the PWM controller to change the time the resistor is connected to the motor. The PWM controller has a switching frequency greater than or equal to 200 Hz. The load reference controller controls the PWM controller by sending a load reference to the PWM controller, said load reference controller having a sampling frequency of greater than or equal to 200 Hz. In this way, a flexible, efficient an fast controlled load can be provided to an exercise machine.

A device for visual walking includes an omnidirectional exercise machine and foot wearable devices. A method for visual walking is applied to the device for visual walking. When a user wears the omnidirectional exercise machine and uses the loading frame to adjust a height of the omnidirectional exercise machine, and wears the foot wearable devices to stand and run on a running plate, human body posture data is obtained by tracking a human body torso. Then displacement data of left and right feet is obtained by tracking the feet. A virtual position and a movement speed of the feet are respectively obtained according to the displacement data, the leg posture is inferred by the IK algorithm according to the virtual position and the walking action of the virtual character is controlled according to the human body posture data, the movement speed of the feet, and the leg posture.
