Physical education is a polarizing topic for many. You either loved it, or you hated it when you were in school. And frankly, physical education hasn’t really changed much in the past few decades – at least when compared to the rapid technological advances that have happened at the same time. Korean startup Twohands Interactive is changing this with Didim, an AR-based exercise solution for businesses like schools, community centers, and malls.

Didim is an interactive playground that lets you and your friends exercise (fitness training, brain training, health games) using your body as the controller. Think Dance Dance Revolution on steroids.

The way it works is pretty clever. Didim consists of a standalone kiosk that’s about the size of a short adult. It’s equipped with a touchscreen, a patented dual lidar system for sensing, and a short throw projector for visuals.

The kiosk is connected to the Internet, enabling payments, plus over-the-air content updates. You can select a game or exercise on the touchscreen, or using your phone (via a dedicated app). The short throw projector displays the game in front of the kiosk in a 10×5.6-foot area – big enough for a few people to play at the same time. A pair of lidar sensors are mounted at ground level on either side of the kiosk, about 6 feet apart.

Didim uses these two lidar sensors to track the position and movement of each player in the game, enabling a rich, low-latency, interactive experience. In addition, the kiosk is easy to move, providing an exercise solution that can be deployed or stowed away on a whim. About 120 businesses are currently using Didim in Korea, but Twohands Interactive has also sold kiosks in Dubai and Japan.

The company is planning to enter other markets, including the US and Canada, and is looking for a distribution and maintenance partner in the US. It’s even considering an alliance with Canadian competitor Lu Interactive.

A kiosk costs about $20,000 to buy, or $3,000 per month to rent, and comes with about 50 games, with 50 more available for $100-$400. Content for the kiosks is typically purchased directly by the businesses.
