In 2014, Utkarsh Tandon, a high school student at Cupertino High School in California, developed a machine learning model for his science fair project to collect and analyze data from patients with Parkinson's disease. He won the first prize and received a prize from the Brain Institute of the University of California, Los Angeles. A year later, Tandon, who became a sophomore, turned his scientific experiments into marketable products. OneRing is now a Kickstarter crowdfunding device that is a wearable device that monitors the tremors of Parkinson's patients. It sends data to the iOS app and the data is displayed in clear and understandable reports.

The name OneRing is taken from JRR Tolkien's Lord of the Rings. A Bluetooth microchip is built into the top of this 3D printed plastic ring. Through the algorithm developed by Tandon, the ring can sense the tremor of Parkinson's patients and generate a daily report based on severity classification to analyze the user's daily trembling. Hand activity patterns can be divided into three categories: dyskinesia, bradykinesia, and tremors. Tandon said: "With these classifications, doctors and patients can read a series of patient reports and use a better drug plan based on the report."

Tandon began learning artificial intelligence and programming fundamentals in the ninth grade, but the seeds of the OneRing project were planted a few years earlier. When Tandon was 10 years old, he saw Muhammad Ali, who ignited the YouTube video of the 1996 Olympic torch. He was curious as to what made Ali's hand shake so badly. Ali was diagnosed with Parkinson's Syndrome in 1984. Tandon began investigating Parkinson's disease and wondering what he could do.

Four years later, Tandon found opportunities in computer science classes in machine learning. During his research, he encountered a data set of research on the Internet that tied mobile phones to the hands of seven Parkinson patients to record their movements. Tandon said: "The data is available online for people who want to track the signs of Parkinson's disease. I was learning machine learning at the time, so I wonder why not try this? I always wanted to do this for Parkinson's patients. Something.” Tandon’s first prototype was a watch-like device that was tied to the user’s wrist. Later, during an internship at the Parkinson Institute near Sunnyvale, California, he gave the patient a prototype, and after the test he decided to change the equipment. In order to make the equipment, he sent the relevant documents to the online 3D printing service company Shapeways. Shapeways sends a small batch of final product to Tandon.

Now, Tandon plans to expand production. His Kickstarter crowdfunding project currently raises twice the target of $1,500, and three days from the end of crowdfunding. The funds raised will be used to produce supporters' OneRing, as well as to allow patients at the Parkinson Institute to use the ring, so that Tandon can further refine the current model. Although the technical part of the ring is impressive, the design of the ring is not fashionable, and Tandon knows this. He said: "It must be something people want to wear. I hope to make it look good and process data in the background." Tandon's next plan is to use flexible polymer materials to make the ring a size. For everyone.
