In order to develop recreational applications, Google is improving its artificial intelligence related to Iris monitoring. A method that also allows the text size to be adapted in real time according to the user's distance.
So that the user in real time can apply augmented reality effects or automatically adapt the screen to their vision based on their distance from the screen, Google opted for the use of artificial intelligence.
The concept was called MediaPipe Iris and the results are published on the company's AI blog.
MediaPipe Iris Applications
In addition to instantly plotting the location of the iris, the developers working on this topic explain that, with their method, the distance between the camera and the user's eye can be determined, without even exploiting a possible depth sensor.
In the case of Mediapipe Iris, Google seeks precision with a minimum of equipment, that is, a simple RGB photo sensor without a depth survey system.
The precision system
The system uses iris reference points so that it can be tracked and analyzed. To evaluate the proportions and carry out its work, AI (Artificial Intelligence) is based on the diameter of the iris of the human eye. This is approximately 11.7 mm with a margin of plus or minus 0.5 mm for the majority of the population.
No depth sensor needed
This method determines the metric distance between the subject and the camera with a relative error of less than 10%. At the moment, the error rate is more important for glasses wearers.
The work carried out is an extension of what Google had already achieved with MediaPipe face Mesh, a system capable of 3D modeling the face in real time without particular hardware other than a single RGB sensor.
In its post, Google points out that Iris monitoring does not allow it to deduce where people are searching and that it does not participate in identity recognition. Rather, the system is designed mainly to develop recreational or practical applications, such as automatically adapting the font size to the distance from the screen.
Additionally, it is capable of working on most mobile phones, computers and even through a web browser.
