METHOD FOR DETECTING GESTURES OF AN EYE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240176136 titled 'METHOD FOR DETECTING GESTURES OF AN EYE
Simplified Explanation
The abstract describes a method for identifying eye gestures using laser feedback interferometry. The method involves emitting a laser beam onto the eye, measuring various parameters such as optical path length, signal-to-noise ratio, and eye speed, and then identifying the eye gesture based on these measurements.
- Emit at least one laser beam onto the eye
- Determine optical path length, signal-to-noise ratio, and eye speed based on laser feedback interferometry
- Identify eye gesture based on the measured parameters
Potential Applications
This technology could be used in various fields such as healthcare, human-computer interaction, and virtual reality for hands-free control and monitoring of eye movements.
Problems Solved
This technology solves the problem of accurately identifying eye gestures in real-time without the need for invasive sensors or physical contact with the eye.
Benefits
The benefits of this technology include improved accuracy and efficiency in detecting eye gestures, non-invasiveness, and potential applications in a wide range of industries.
Potential Commercial Applications
- Healthcare: for monitoring eye movements in patients with neurological disorders
- Human-computer interaction: for hands-free control of devices
- Virtual reality: for enhancing user experience through eye gesture recognition
Possible Prior Art
One possible prior art could be eye tracking technology used in virtual reality headsets or medical devices for monitoring eye movements.
What are the specific parameters measured in this method?
The specific parameters measured in this method include optical path length, signal-to-noise ratio, and eye speed.
How does laser feedback interferometry help in determining eye speed?
Laser feedback interferometry helps in determining eye speed by analyzing the Doppler shift of the emitted radiation and the radiation scattered back from the eye. This shift is used to calculate the speed of the eye movement accurately.
Original Abstract Submitted
a method for identifying eye gestures of an eye includes the steps of emitting at least one laser beam onto the eye determining a single measuring sample having current values for: an optical path length of the emitted laser beam; a signal-to-noise ratio of radiation scattered back from the eye; an eye speed of the eye; and identifying an eye gesture based on the single measuring sample, wherein the optical path length is determined based on laser feedback interferometry of the emitted laser radiation with the radiation scattered back from the eye, and wherein the eye speed is determined based on a doppler shift of the emitted radiation and the radiation scattered back, determined by means of the laser feedback interferometry.
