Method and Apparatus for Operatively Controlling a Virtual Reality Scenario with an Isometric Exercise System

Abstract

An interface, in the form of an isometric exercise system, according to the present invention includes an effector with at least one sensor, a platform and control circuitry including a processor. The platform accommodates a user in a standing position and includes the effector attached thereto. The sensor measures at least one force applied by a user lower body portion to the effector and causing a measurable strain on the effector. An additional effector with at least one sensor and a game controller or other input device may further be attached to the platform. The sensor measures at least one force applied by a user upper body portion to the additional effector and causing a measurable strain on that effector. The processor receives and processes data corresponding to applied force information for transference to the host computer system to update a virtual reality scenario.

AI Technical Summary

Benefits of technology

[0026] The present invention provides several advantages. In particular, the isometric interaction inverts the paradigm utilized by the related art devices (such as the CyberForce and the Treadport). In contrast to that paradigm (e.g., allowing the user to move freely and apply unrealistic forces), the isometric interaction of the present invention enables the user to exert realistic forces, while constraining the motion. The ramifications are considerable and include attaining the desired effect without moving parts and the associated high cost and mechanical complexity. Further, reaction times are immediate since there is no lag required for some mechanism to reflect the new state of the simulated world. Moreover, the user may apply forces equivalent to those the user applies in the real world to cause a synthetic object to move in the simulation. Since the present invention employs no moving parts, the isometric interface is extremely simple, rugged and inexpensive. This in combination with the small size of the interface make the interface extremely suitable for group training both in traditional training environments as well as forward deployments. Thus, the present invention system provides a level of integrated physical and cognitive training comparable to systems with significantly greater cost. In addition, the present invention enables a user to perform upper and / or lower body isometric exercises to interact with a virtual environment or game, thereby facilitating exercise and consumption of an increased quantity of calories during game play.

Problems solved by technology

However, if the soldier has been trained in an environment where the physical component of the activity has not been taken into account, the soldier can possibly commit to a course of action that the soldier is physically incapable of performing (e.g., sprinting up to a roof with a heavy pack and calmly engage in sniper activity, etc.).

However, problems exist with respect to including physical interfaces in dismounted soldier type simulations.

These problems relate to technology and cost.

In particular, interfacing with the human body is an extremely challenging problem.

The mechanical complexity of the interface rises sharply with the number of axes along which the soldier can move.

On the other hand, the Treadport is capable of supporting motion in the X and Y axes along with up to thirty degrees of slope, but is extremely impractical and uneconomical.

Further to the cost and complexity of these systems, robotic force type feedback systems are limited and can only apply a small portion of the opposing force that the systems are capable of producing.

Since a trivial malfunction of hardware and / or software results in a maximum force being applied, the machine motors of these systems are restricted to prevent injury to the user.

The restricted operation prevents the systems from applying sufficient force to simulate hard, impenetrable surfaces in the virtual environment.

This lack of sufficient exercise may contribute to a growing population of overweight people or even an epidemic of obesity.

As a result, the subject can only play the game by performing certain isometric exercises.

However, the above-described exercise systems of the related art suffer from several disadvantages.

In particular, interaction between the exercise system and a computer in the previously described International Publication is limited to simple representations on a display that are based upon achieving set goals.

Thus, this exercise system does not provide a fully interactive virtual reality environment (e.g., controlling a variety of movements of a character or an object in the scenario as well as other features relating to the scenario).

Further, the system is generally not universally compatible with various gaming or other processors and associated “off the shelf” gaming or other applications.

This limits the applications for which the system may be utilized.

In addition, the system is bulky and includes various components for operation, thereby complicating portability and use for exercise at various locations.

Thus, the system is generally not universally compatible with various gaming or other processors and associated “off the shelf” gaming or other applications.

This limits the applications for which the system may be utilized.

Further, the system includes various components requiring assembly for operation, thereby complicating portability and use for exercise at various locations and preventing immediate (e.g., plug and play type) operation.

In addition, the IVES system is limited to isometric knee and ankle exercises and, thus, is incapable of being utilized in a variety of different contexts where it is desirable to exercise upper body parts alone or in combination with lower body parts of a user.
