We’re not trying to replace what’s already there, but make tennis more accessible. Somehow in tennis you have to do everything yourself: call the lines, keep score. And even middle-school basketball has refs. We’re starting to see more high school players as well as people who just rally with their friends, and for me that’s the biggest opportunity: How can we teach people to play tennis? How can we automate scoring, make it more accessible? Because tennis has a really weird scoring system. But really it’s for anyone who’s keeping score. Right now, it’s most popular among club players, adults who are playing competitively maybe once a week. So I was like, “You know, if you log into Find My iPhone, it can ping the phone for you.” And he said, “Is that real? Is that a thing?” So that’s how we found his iPhone. James tried to call it, but it was on silent. But I think what really sold him was that he had to leave to catch a flight and couldn’t find his iPhone. We’re in the locker room, and I pitched all of them, but Andy was the most interested. We were in Texas at an exhibition match with Andy Roddick, John McEnroe, and Jim Courier. I’ll tell you a story: James was the first tennis pro I met. Both the videos are divided into equal number of frames. SINPUTVIDEO is the sample video of the user, SPLAYERVIDEO denotes the video of professional player. Tennis pros Andy Roddick and James Blake are investors. In the second component we compare user’s input video with professional tennis player videos. We changed one line of code on the computer in Python before making the conversion, and then everything worked. That conversion step wasn’t working properly, and we were panicking, like, “We’re never going to figure this out! This company is gonna fail!” It took several weeks hunting online forums, but we found the fix-and it was literally one line. With most machine-learning models, you train it on a computer and then convert it to Core ML to run on iPhone. Apple Watch is an integral part of SwingVision, but the iPhone opens up so much because you can use its camera.Ībout a year and a half ago, we were building the AI that would track shots with the single camera. While doing that, I thought, “Wait, I could do this for tennis too.” Apple was making iPhones with bionic chips that were so powerful, and I realized this could actually be possible. How did you move the app from Apple Watch to iPhone?Īfter I graduated, I worked on autonomous driving and became well versed in computer vision-tracking cars and pedestrians using AI. It seemed more approachable than Objective-C, so I thought, “Maybe I can pick this up on my own.” Swift was incredible it’s a great first language for anyone who’s trying to learn coding. I was at Columbia University doing my PhD when Swift came out. Yeah, I basically taught myself Swift so I could make an Apple Watch app to track my shots and keep score.
