"Do you mean you have to keep watching?"

Qiao Liang turned his gaze to his own face in the mirror and found that the position he was looking at seemed to have a faint highlight effect, constantly changing its position as his gaze moved.

"Eye tracking?"

Qiao Liang was a little surprised and a little surprised.

Eye tracking is not a very high-end technology. It has appeared in the past two years. By using the camera to detect the status of eye muscles and pupils, you can roughly determine the position of the screen you are looking at.

There are many software on the Internet now that can achieve the effect of eye tracking.

Of course, this technology is not as beautiful as imagined. The first thing is to ensure that the person's face is facing the camera and to collect data points. Just now Qiao Liang was staring at the movement of the blood stain, which was obviously what he was doing.

The whole process is rather cumbersome, and Mr. Pei's simple packaging makes it seem a bit weird and more immersive.

Secondly, the accuracy of eye tracking is very low. It can only roughly determine a large range of where the eyeballs are looking, but cannot be particularly precise.

However, it seems to be sufficient for this test.

Qiao Liang began to stare at his face in the mirror attentively.

However, after a few seconds, he suddenly felt something was wrong.
