Method for calibrating the physical position and orientation of an electronic device using device sensors only

A sensor position system, comprising:

• a portable programmable electronic device having a visual display screen and at least one motion sensor;
• and
• an executable sensor position system program loaded onto said electronic device, said program including executable instructions which visually display a two- or three-dimensional virtual representation of a user-selected physical space on the electronic visual display, enable a user to mark an initial reference point in the displayed virtual representation of the physical space, receive a data signal from said at least one motion sensor, evaluate the data signal from said at least one motion sensor so as to distinguish walking and running movements from other movements, and when the movement is determined to be a walking or running movement that moves the electronic device from the initial reference point to a new point within the physical space, causes the electronic data device to calculate the direction and distance traveled by the user and to display an end reference point in the virtual representation of the physical space;
• wherein data from electronic positioning systems physically independent from said electronic device are not used.
