Abstract: A “human motion tracking” device (HMT) that translates natural body movements into computer-usable data. The data is transmitted to a simulation application as if it came from any conventional human interface device (HID). This allows an individual to interact with the application without the need for a conventional computer input device (e.g., a keyboard, mouse, etc.). The HMT captures a user's heading as well as the individual's current stance (i.e. standing, sitting, kneeling, etc.). The HMT accomplishes this by using two sensors known as an accelerometer and magnetometer to produce digital input. The digital data will then be passed from the HMT to the application.
