Wow, I can’t believe it! This new  AI can look at a real tennis player,   and put them in a computer game where we can  play with them. This looks absolutely amazing,   and doing this the hard way has  so far been absolutely impossible. But what about the easy way? Exciting as this may  seem, perhaps there is nothing new here. You see,   we can alr... Read More

Questions & Answers

Q: How does the AI generate realistic virtual tennis players?

The AI analyzes raw video footage of real tennis players and estimates their motion. It then builds a computer simulation within a video game to reproduce the motion realistically.

Q: What is the advantage of this AI-generated simulation compared to traditional motion capture?

Unlike traditional motion capture, this technique does not require any additional equipment like cameras or sensors. It can generate realistic motion purely from raw video feed, eliminating the need for tedious setup and calibration.

Q: Can the AI learn individual player styles?

Yes, the AI can learn and simulate the individual playing styles of famous tennis players, including their hand preference and specific stroke techniques.

Q: How accurate is the simulation?

The simulation is highly accurate, with foot sliding reduced to less than an inch and minimal jitters from the original motions. When the full system is used, hit rates can reach up to 100%, showcasing the precision of the AI-generated simulation.

Summary & Key Takeaways

• Researchers have developed a technique to generate realistic virtual tennis players using AI and raw video footage.

• The AI analyzes the video feed and estimates the players' motion, creating a simulation within a video game.

• The simulation allows for accurate and believable motion types, individual player styles, and even two-player matches.
