COMPUTER INTERFACE DEVICE WORN TO HEAD BASED ON LOOKING DIRECTION OF EYES, AND METHOD THEREOF

摘要

PURPOSE: A computer interface device worn to a head based on a looking direction and a method thereof are provided to accurately calculate a looking direction vector on the 3D(Dimensions) by extracting motion data of the head/eyes in every moment and applying various correction methods for expressing the extracted data on the 3D coordinates. CONSTITUTION: A magnetic sensor comprises a transmitter and a receiver(13). A relative 3D position and a rotational quantity between the transmitter and the receiver are calculated in a magnetic sensory information processor(22) and transmitted to a computer(24). A CCD(Charge Coupled Device) camera(12) pictures an image of the eye(21) through a mirror(15) and transmits the image to an image processor(23). The image processor calculates the vector expressing the motion of the eye and transmits the vector to the computer. The looking direction vector of the eye is calculated based on the 3D coordinate system by using the motion data of the head and the eye. A looking point on a monitor(17) is calculated by calculating an intersection point of the looking direction vector and the monitor.
