LINE-OF-SIGHT DETECTING APPARATUS, IMAGE PICKUP APPARATUS, LINE-OF-SIGHT DETECTING METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240114228 titled 'LINE-OF-SIGHT DETECTING APPARATUS, IMAGE PICKUP APPARATUS, LINE-OF-SIGHT DETECTING METHOD, AND STORAGE MEDIUM

Simplified Explanation

The patent application describes a line-of-sight detecting apparatus that uses an eyeball image to estimate the gaze point position of a user on a display element. The apparatus then performs calibration to reduce the difference between the estimated gaze point position and the actual gaze point position of the user. If needed, the calibration can be repeated based on changes in the user's pupil diameter. The user is notified if recalibration is necessary, and the process can be repeated if instructed by the user.

  • Processor acquires estimated gaze point position based on eyeball image
  • Calibration is performed to reduce difference between estimated and actual gaze point position
  • Recalibration may be needed based on changes in user's pupil diameter
  • User is notified if recalibration is necessary
  • Recalibration can be repeated if instructed by the user

Potential Applications

This technology could be applied in eye-tracking systems for various industries such as gaming, virtual reality, and assistive technologies for individuals with disabilities.

Problems Solved

This technology solves the problem of accurately determining a user's gaze point position on a display element, which is crucial for applications like eye-controlled devices and interactive systems.

Benefits

The benefits of this technology include improved accuracy in detecting a user's line of sight, enhanced user experience in interacting with devices, and potential advancements in eye-tracking technology.

Potential Commercial Applications

  • "Enhancing User Experience with Advanced Eye-Tracking Technology"

Possible Prior Art

One possible prior art in this field is the use of eye-tracking technology in virtual reality headsets to improve user immersion and interaction.

What are the potential limitations of this technology in real-world applications?

The potential limitations of this technology in real-world applications could include challenges in accurately calibrating the system for different users with varying pupil sizes and shapes. Additionally, environmental factors such as lighting conditions and screen reflections could affect the accuracy of the line-of-sight detection.

How does this technology compare to existing eye-tracking systems on the market?

This technology offers the advantage of automatic recalibration based on changes in the user's pupil diameter, which can improve the accuracy of gaze point detection over time. Existing eye-tracking systems may require manual recalibration or lack this feature, making them less adaptable to changes in user behavior.


Original Abstract Submitted

a line-of-sight detecting apparatus includes a processor configured to acquire an estimated gaze point position of a user on a display element based on an eyeball image, perform calibration for the estimated gaze point position to reduce a difference between the estimated gaze point position and an actual gaze point position of the user, determine whether or not the calibration is to be performed again based on a difference between a first pupil diameter of the user when the calibration was performed and a second pupil diameter of the user when the estimated gaze point position was acquired based on an eyeball image acquired after the calibration, notify the user of information about performing again the calibration in a case where it is determined that the calibration is to be performed again, and perform again the calibration in a case where it is determined that the user has instructed to perform again the calibration according to notified information.
