Real time simulation using position sensing

A storage unit which is readable by a computer system able to dynamically control an exercise machine and a video playback means, the storage unit comprising:

• a storage media unit;
• course data including locational information and force information for points along a real exercise course stored on said storage media unit, thereby permitting the computer system reading an instance of the storage unit to dynamically control the exercise machine so that users experience a simulation of physical forces which would be encountered at specific locations along said real exercise course;
• and
• video data including captured natural video image sequences from said real exercise course stored on said storage media unit, thereby permitting the computer system to also control the video playback means so that said users experience a simulation of traveling through said real exercise course.

A method of making a storage media which is readable by a computer system to dynamically control an exercise machine and operate a video playback means, the method comprising:

• collecting locational information for points along a real exercise course;
• collecting terrain characteristic information for said points;
• creating course data by associating said locational information and said terrain characteristic information;
• collecting video data including captured natural video image sequences;
• and
• storing said course data and said video data in a computer readable media unit, thereby permitting the computer system reading an instance of said media unit to dynamically control the exercise machine so that users experience a simulation of terrain characteristics which would be encountered along said real exercise course and further permitting the computer system to play said video data on the video playback means so that said users also experience a simulation of traveling through said real exercise course.
