According to foreign media reports, the improved visual control system can greatly promote the exchange of severely disabled people, and even the hands of pilots and surgeons.
French visual research expert JeanLorenceau found that humans can write on the computer screen with the help of eye movements, but the fonts are a bit sloppy. This invention can greatly help the more disabled people to communicate more freely, and it is also very likely to promote the birth of visual control systems, especially for pilots, drivers and surgeons.
Laurento is the head of the research department at the French National Centre for Scientific Research. He is the research at the University of Paris VI (Pierre and Marie-Curie University). CurrentBiology has reported on his research on Thursday.
In recent years, researchers have invented a number of communication systems for severely disabled people who generate signals based on brain waves generated by the brain or movement of the eye. As long as you bring the electrode or headgear that tracks the movement of the eyeball, the cursor of the computer will move according to the movement of the eyeball, and then control the letters on the screen or write the information you want to express by selecting one letter at a time.
However, under normal circumstances, the instinct movement of the eyeball is almost impossible to meet the requirements of writing a neat letter or drawing a beautiful work. The focus of this study is on the rapid movement of the eyeball, which is the so-called saccade. This is also the fastest move humans can make.
In order to stabilize the movement of the eye, Laurento launched a visual research project called reversephimotion. The project is designed to help people accurately control eye movements and achieve the requirement to write identifiable writing. In the study, the tester took an infrared camera and transmitted the movement of the eyeball to the screen.
Dr. Lorenzo revealed that although the instrument research project has only achieved initial success, as long as it accepts 3 to 5 training sessions (30 minutes per training session), people can use the technology to write 20 minutes on the computer screen every minute. 30 characters. Laurento said that he is satisfied with the technology after training, and that the writing speed is still relatively fast, whether it is the speed of writing numbers, letters or words can reach the speed of his own handwriting.
