CORNEAL REFLECTED IMAGE IDENTIFYING DEVICE AND GAZE DETECTION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18358124 titled 'CORNEAL REFLECTED IMAGE IDENTIFYING DEVICE AND GAZE DETECTION DEVICE
Simplified Explanation
The patent application describes a device that can accurately detect a person's gaze even when they are wearing something that covers their eyes. The device includes a light projecting part that projects light from two sources towards the person's eye, and a camera that captures an image of the eye with the projected light. A distance calculating part uses the captured image to calculate the distance between reflected images of the projected light. A corneal reflected image identifying part then identifies the corneal reflected image to be used for gaze detection, by excluding the reflected image of the projected light that is reflected by the object covering the eye based on predetermined features.
- The device can accurately detect a person's gaze even when they are wearing something that covers their eyes.
- It uses two light sources to project light towards the person's eye.
- A camera captures an image of the eye with the projected light.
- A distance calculating part calculates the distance between reflected images of the projected light.
- A corneal reflected image identifying part identifies the corneal reflected image to be used for gaze detection.
- The identified corneal reflected image is used for gaze detection by excluding the reflected image of the projected light that is reflected by the object covering the eye based on predetermined features.
Potential applications of this technology:
- Eye tracking systems for virtual reality or augmented reality applications.
- Assistive devices for people with disabilities, such as controlling a computer or wheelchair with eye movements.
- Market research and advertising, by analyzing a person's gaze patterns to understand their interests and preferences.
Problems solved by this technology:
- Accurately detecting a person's gaze even when they are wearing something that covers their eyes.
- Overcoming the limitations of traditional gaze detection systems that rely on direct eye contact.
Benefits of this technology:
- High precision gaze detection.
- Improved usability and accessibility for individuals wearing eye-covering objects.
- Enhanced user experience in virtual reality and augmented reality applications.
- Potential for new insights and applications in market research and advertising.
Original Abstract Submitted
A corneal reflected image identifying device and gaze detection device enabling detection of a gaze with a high precision even when a person being monitored is wearing an object covering the eyes, in particular a corneal reflected image identifying device comprising a light projecting part for projecting light from two light sources which are spaced apart from each other toward an eye, a camera for capturing an image of the eye on which light is projected, a distance calculating part for using the captured image to calculate a distance between two reflected images for each combination of two reflected images among a plurality of reflected images obtained by light projected from the light sources being reflected in a vicinity of the eye, and a corneal reflected image identifying part for excluding a reflected image of light projected from the light sources being reflected by an object covering the eye based on predetermined features and identifying a corneal reflected image to be used for gaze detection, wherein the predetermined features include the distance which the distance calculating part has calculated.
