ELECTRONIC DEVICE FOR OBTAINING FEATURE POINT FROM CODED IMAGE AND METHOD FOR OPERATING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18208102 titled 'ELECTRONIC DEVICE FOR OBTAINING FEATURE POINT FROM CODED IMAGE AND METHOD FOR OPERATING THE SAME

Simplified Explanation

The abstract describes an electronic device that uses a light source, pattern mask, and image sensor to obtain gaze information of a user based on their eye movements. Here is a simplified explanation of the abstract:

  • An electronic device is designed to track a user's gaze using their eye movements.
  • The device includes a light source that emits light.
  • A pattern mask is used to change the path of the light transmitted through a pattern.
  • An image sensor receives the light that is reflected by the user's eye and transmitted through the pattern mask.
  • The device includes at least one processor that processes the received light to obtain a coded image that is phase-modulated based on the light transmitted through the pattern mask.
  • The processor then identifies a feature point of the user's eye from the coded image.
  • Based on this feature point, the processor obtains gaze information of the user.

Potential applications of this technology:

  • Eye-tracking systems for virtual reality or augmented reality devices.
  • Assistive technology for individuals with disabilities, allowing them to control devices using their gaze.
  • Market research and user experience testing, providing insights into where users are looking on a screen or in a physical environment.

Problems solved by this technology:

  • Accurately tracking a user's gaze can be challenging, but this technology provides a solution by using a pattern mask and coded image processing.
  • Traditional eye-tracking systems may require complex and expensive hardware, but this technology offers a more efficient and cost-effective approach.

Benefits of this technology:

  • Improved user experience in virtual reality or augmented reality applications by enabling more natural and intuitive interaction.
  • Accessibility for individuals with disabilities, allowing them to navigate and control devices using their gaze.
  • Valuable insights for market research and user experience testing, leading to better design and optimization of products and interfaces.


Original Abstract Submitted

An electronic device includes a light source configured to output light, a pattern mask configured to change a path of light transmitted through a pattern of the pattern mask, an image sensor configured to receive light that is output from the light source, reflected by an eye, and transmitted through the pattern mask, and at least one processor configured to obtain a coded image that is phase-modulated based on light transmitted through the pattern mask, obtain a feature point of the eye from the coded image, and obtain gaze information of a user based on the feature point.
