  2. Sports of the Future

Sports of the Future

Greetings

Sports of the Future is a joint research initiative with Japan’s High Performance Sports Center, a core facility that supports Olympic athletes in achieving peak performance.
We work alongside top researchers and athletes to help them reach their goals — whether it’s through millimeter-accurate motion capture, intuitive data visualizations, easy-to-use in-game interfaces, or tools for nutrition and harassment prevention.

So far, we’ve supported curling athletes and plan to expand to other sports as well. Let’s use technology to support the future of sports and explore exciting new possibilities together!

Tablet Stone



Realizing a curling stone that maintains a stable information display no matter how much the stone is spinning
Tablet Stone is an application that was developed for players of curling. This application begins with the placing of a tablet on top of a curling stone. On the tablet, information such as the stone’s movement speed, rotation speed and number of rotations is displayed. This information is important for, for example, the sweepers (the players who sweep the ice with brushes). However, because a curling stone spins as it travels, it is difficult for the sweepers to read information displayed on top of the stone. By making the information display rotate in response to the rotation speed of the stone as it slides across the ice, we make it easy for players to read the data. But seeing is believing, so check out the demo video!

Stone Recoder



Turning curling stones into science

Often called `chess on ice’, curling is known to be a competitive sport that is extremely tactical. However, how the stones used in the sport will move on the ice, and the physical mechanism involved, have yet to be made clear. StoneRecorder uses infrared LEDs and an infrared camera to record the movement of stones and displays their trajectories on the rink, using projection mapping. Making it possible to visualize or predict the trajectory of the stones could change both tactics and practise, and even the nature of spectation.

Smart Bowling Ball



Perceptive bowling ball

To become good at bowling, it is necessary to consider various factors, such as approach, form and the speed and number of rotations of the ball. However, it is impossible to grasp exactly what state the ball is in once it has been bowled. Smart Bowling Ball has several sensors embedded in it, endowing it with sensory information. By reading the information recorded by the ball, such as speed and rotation, it is possible to confirm the status of the ball after bowling, in more detail and in numerical values. Perhaps we will see a future in which the ball itself gives you advice on your bowling.

Toricolle



Snowboarder’s SNS! Trick & Collection

Toricolle is an SNS for snowboarders attempting tricks. Users can share tricks that they have invented with other snowboarders on the SNS. In addition, a sensor mounted on the user’s snowboard enables automatic judgement of whether or not tricks have been successfully performed. Users are awarded badges for attempting and mastering the tricks they have created themselves and those created by other users. Toricolle snowboarders can enjoy building a trick collection, honing their skills and connecting with Toricolle snowboarders around the world, through tricks.
