1 . This year’s Olympic Games have been closed to most spectators (观众) because of COVID-19, but the eyes of the world are still on the athletes thanks to five extra cameras—the first step in a 3D tracking system that supplies spectators with instant insights into each step of a race.
The tracking system being used in Tokyo, an Intel product called 3DAT, feeds live footage (影像) into the cloud. There, an artificial intelligence program uses deep learning to analyze an athlete’s movements and identifies key performance characteristics such as top speed and slowdown. The system shares that information with viewers by displaying the action of slow-motion, highlighting key moments. The whole process, from capturing the footage to broadcasting the analysis, takes less than 30 seconds.
“It’s like having your own personal commentator point things out to you in the race,” says Jonathan Lee, director of the Olympic technology group.
To train their Olympic AI via machine learning, Lee and his team had to capture as much footage of best athletes as they could. They needed recordings of human bodies performing specific moves, but the preexisting footage shows average people in motion, Lee says. “People aren’t usually seven feet in the air,” he notes, but world-class high jumpers reach such heights regularly.
In the footage, a team at Intel record every part of the body—eyes, nose, shoulders, and more. Once those key points were identified, the model began connecting them in three dimensions (维度) until it had a simplified performance of an athlete’s form. Lee thinks the AI could help everyone from Olympians to average gymgoers correct their form and track changes in their moves that may indicate upcoming injury. “Long-term, what this technology will do is help improve an athlete’s performance by giving them more information,” two-time Olympic champion Ashton Eaton said.

More about TED Countdown:
On January 25, we’re hosting the Countdown Summit in Scotland— the firstTED conference focusing on climate solutions. In April, TED hosted an online meeting and announced our plan to help the planet. And as always,education plays an important role in this mission (使命). That’s why we have chosen talks for students to do together virtually for a deeper understanding of this global issue and solutions.
We hope your students join us!
Please note that this event is only for studenst aged 3-19, in high school and below!

I can't believe I'm senior high student now! How amazed the new school life is! All the students and teacher in my class are friendly and helpful, and they have become my friends. The campus is twice as larger as my junior high school. The classrooms are big enough to holding 50 students. I'm deep impressed with the modern equipment in my classroom, where helps us study conveniently.However. the subjects we are learning now were far more difficult than before. As a result of,I have to spend a lot of time studying by myself.But after class I still take part in the activities so that I can relax myself but improve my health. I love my new school life.

In order to celebrated National Day and the Mid-Autumn Festival, and we had an 8-day holiday. After it, my classmates and I were talking about how to do during the holiday excitedly. Then we decided to go to help the farmers instead of stay at home. As soon as we arrived at farm, we were attracted by the apples hanging on the branches. We couldn't wait to pick the apples, which were the most interesting work. Particular, we were allowed to choose what we liked best and taste them. We didn't feel boring at all even though the job was tiring. We worked for 5 hours happily unless the sun set.
