Embodiments of the present disclosure relate to a two-person exercise wheel. The two-person exercise wheel may include an exercise ring, a non-equilateral parallelogram linkage mechanism, a tension spring, and a suspension seat. When the ring is rotated, the non-equilateral parallelogram linkage mechanism may be rotated by a rocker arm. In some embodiments, the gravitational forces and the tension spring connected between the two seats act on the ring via the non-equilateral parallelogram linkage mechanism and the rocker arm. In some embodiments, the supporting force of the ring may pass through a circular center. Further, the gravitational forces may act on the non-equilateral parallelogram linkage mechanism and the persons on the seats may pedal to enable the ring to gain a rotation torque. Further, the tension spring may adjust the torque between the seats and the circular center when the two seats are in positions different from each other.

Method and system for visualizing dynamic virtual sub-systems of a virtual simulated element in an interactive computer simulation system comprising a computer generated environment. One or more tangible instruments control the virtual simulated element in the computer generated environment. A graphical user interface comprising an interactive display portion depicting a rendered view of the virtual simulated element. While an interactive computer simulation of the virtual simulated element is performed in the interactive computer simulation system, a storage system logs dynamic data in relation to the dynamic virtual sub-systems. At least one of the dynamic virtual sub-systems of the virtual simulated element is selected and a subset of dynamic data related to the selected virtual sub-system is loaded from the storage system. The selected virtual sub-system is displayed together with the related dynamic data on the graphical user interface.

Method and system for dynamically modifying visual rendering of a visual element in a computer generated environment from an interactive computer simulation is provided. Pre-defined visual characteristics are associated with the visual element. A tangible instrument module is used to provide one or more commands for controlling a simulated vehicle of the interactive computer simulation. At the interactive computer simulation station, dynamically affecting the visual element is performed by enhancing at least one of a visual contouring of the visual element and one or more pre-identified distinctive visual characteristics of the visual element. Tailoring parameters determined considering at least one of an identity of the trainee in the interactive computer simulation station and an identifier of the visual element are considering when dynamically affecting the visual element in real-time during execution of the interactive computer simulation prior to rendering the visual element for display.
