ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18558214 titled 'ELECTRONIC DEVICE

The abstract describes an electronic device that can detect a user's body movements, specifically the blinking action, to estimate the user's fatigue state.

  • The electronic device is worn in front of the user's eye and includes a display apparatus and a light source in a housing.
  • The display apparatus consists of a light-emitting device and a light-receiving device in a display portion.
  • Light emitted by the light source is reflected off the user's eye and eyelid, with the reflected light detected by the light-receiving device.
  • The device can differentiate between the amount of light reflected by the eyelid and the eyeball, enabling the detection of the blinking action.
  • By detecting the blinking action, the device can estimate the user's fatigue state.

Potential Applications: - Monitoring fatigue levels in drivers or operators of heavy machinery. - Assessing alertness in medical professionals during long shifts. - Tracking fatigue in athletes during training or competitions.

Problems Solved: - Provides a non-intrusive way to monitor fatigue levels in real-time. - Offers a more accurate assessment of fatigue compared to self-reporting.

Benefits: - Enhances safety by alerting individuals when they are fatigued. - Improves performance by optimizing rest periods based on fatigue levels.

Commercial Applications: Title: "Fatigue Monitoring Device for Enhanced Safety in Various Industries" This technology can be utilized in transportation, healthcare, and sports industries to enhance safety and performance by monitoring fatigue levels in real-time.

Questions about the technology: 1. How does the device differentiate between the amount of light reflected by the eyelid and the eyeball? 2. What are the potential privacy concerns associated with using this technology in various industries?


Original Abstract Submitted

An electronic device capable of detecting a user's body movements is to be provided. The electronic device is display equipment worn in front of the user's eye and capable of detecting the blinking action. The electronic device includes a display apparatus and a light source in a housing, and the display apparatus includes a light-emitting device and a light-receiving device in a display portion. Light emitted by the light source is incident on the user's eye and the vicinity thereof through a mirror and reflected, and the reflected light is detected by the light-receiving device. The amount of light reflected by the eyelid and that by the eyeball are different from each other, which enables the blinking action to be detected. The detection of the blinking action enables the user's fatigue state to be estimated.
