3D Image Pointer Selection Using Eye-Tracking Vectors

The patent replaces manual mechanical operations (mouse movements, clicks, and coordinate input) with an eye-tracking system that uses optical detection to automatically determine spatial position coordinates. The eye tracker captures eye position data and the processor automatically converts this into three-dimensional spatial coordinates, eliminating the need for complex manual input operations while maintaining precise selection capability.

The system enables self-service operation where the user's natural eye movements automatically control the selection of spatial position coordinates. The eye tracker continuously monitors eye position and the processor automatically translates this into three-dimensional coordinates and performs the corresponding image manipulation operations, eliminating the need for the user to manually process images or input coordinates, thereby significantly reducing operation time and increasing productivity.

The patent introduces an eye tracker and processor as intermediary devices between the user and the three-dimensional display system. The eye tracker serves as the mediator that captures eye position data, and the processor acts as the intermediary that converts this data into precise three-dimensional spatial coordinates. This intermediary system maintains measurement precision while eliminating the need for the user to understand or input complex operating instructions, as the system automatically handles the coordinate transformation and selection process.
