RETINAL REFLECTION TRACKING FOR GAZE ALIGNMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18138233 titled 'RETINAL REFLECTION TRACKING FOR GAZE ALIGNMENT
Simplified Explanation
The patent application describes devices, systems, and methods that can detect the direction of a person's gaze towards a specific area and initiate an action based on that.
- The system uses an illuminator to direct light towards the person's eye, creating a reflection.
- A sensor receives data from the reflection and determines its reflective properties, such as its spectral properties.
- By analyzing the reflective properties, the system can detect if the person's gaze is directed towards a specific target area, like a hot corner or zone.
- Once the system detects the gaze direction towards the target area, it can initiate an action based on this information.
Original Abstract Submitted
Various implementations disclosed herein include devices, systems, and methods that initiate an action based on a detected gaze direction oriented towards a target area (e.g., a hot corner/zone). For example, an example process may include producing a reflection by directing light towards an eye using an illuminator, receiving sensor data from a sensor, wherein a direction of sensing by the sensor (e.g., the optical axis of the camera) and a direction from the eye to a target area are approximately aligned, determining a reflective property (e.g., a spectral property) of the reflection based on the sensor data, detecting that a gaze direction of the eye is approximately oriented towards the target area (e.g., a hot zone/spot) based on the reflective property, and initiating an action based on detecting that the gaze direction is approximately oriented towards the target area.
