Tokyo, November 9, 2022 –On October 23, 2022, Rakuten Mobile, Inc. (“Rakuten Mobile”) successfully performed a demonstration of motorsport that combines the real and the virtual in the 2022 Inter Proto Series POWERED BY KeePer Round 2 held by Inter Proto Motor Sports Co. , Ltd.*1. With 4G and 5G mmWave, provided by Rakuten Mobile, an e-race was successfully conducted that merged the real and virtual through remote transmission of driving data, and the real-time synchronous Augmented Reality (AR) display of the virtual car and car race information during the race*2.

This demonstration experiment was carried out simultaneously at two locations: Fuji Speedway, the venue of the 2022 Inter Proto Series POWERED BY KeePer Round 2 in Shizuoka Prefecture, and the Rakuten Mobile Ebisu Store in central Tokyo. The test car named “kuruma”*3 raced on the circuit at Fuji Speedway against the virtual car driven by E-Racer using the racing simulator in the Rakuten Mobile Ebisu Store, using data from both sources.

Overview of the event:

1. Implementation of an e-race that merges real and virtual through remote transmission of driving data

2. Real-time synchronous AR display of virtual cars and races and AR display of car race information

1. Implementation of an e-race that merges real and virtual through remote transmission of driving data
By transmitting the data of the test car driven by the actual racing driver at Fuji Speedway in real time to the racing simulator driven by the e-racer in the Rakuten Mobile Ebisu Store, the e-racing between the test car and the virtual car was successfully displayed on the game screen. A telemetry system*4 Provided by M-TEC Co., Ltd. *1 that receives and transmits data from sources including various sensors to measure the steering angle and other factors, GPS and cameras installed in the test car running on the circuit, enabling the display of an equivalent virtualized test car for e-racing at Game screen. 5G mmWave was used for communication between the racing simulator and the game server to realize a realistic racing experience in real time.

2. Real-time synchronous AR display of virtual cars in races and AR display of Auto racing information
At Fuji Speedway, by using a smartphone equipped with a special mobile app developed by Rakuten Mobile in the spectator seat, or wearing smart glasses and watching the race, spectators could see the race between the test car actually on the run real-life circuit and drive the virtual cars of the e-racers competing in the Rakuten Mobile Ebisu Store. In addition, driving data such as car position, speed and engine speed generated by the test car and virtual car in motion, the perspective video of the racing driver, and the game screen video of the E-Race were also available to show on the same app. Courtesy of Immersal Ltd’s*1 VPS (Visual Positioning System) technology, it was also possible to show AR content to spectators in places around the circuit with higher accuracy.
