First in Japan Joint Demonstration of "hitoe" to Measure Racing Car Driver Biological Data at the 2017 All Japan Super Formula Championship

~ Realizing higher performance using driver biological data and vehicle data ~

In cooperation with Dandelion Ltd. (“Dandelion”), who operate “DANDELION RACING” car racing team, NTT DOCOMO Corp. (“NTT DOCOMO”), NTT Data Corp. (“NTT Data”), and NTT Corp. (“NTT”) have begun a joint demonstration measuring driver biological data using “hitoe”*1 during the All Japan Super Formula Championship (“Super Formula”) starting on Saturday, April 22, 2017.

The demonstration was done to visualize driver bodily function and driving conditions in the Super Formula environment, on circuit layouts with repeated sudden acceleration and breaking. Bodily data was measured using a functional material "hitoe", which can measure biological data continuously. Data can be measured, including electro-cardio waveforms and heart rate, by simply having the driver wear an undershirt with "hitoe" ("hitoe wear").

By analyzing this biological data together with racing car driving data (speed, acceleration, tachometer, break pressure, etc.) and video of the driving conditions from onboard cameras, any correlations between the driver's bodily state and driving state during the high-speed race can also be studied. This holds promise for studying driver management and training.

In the past, vehicle data in the racing environment was collected with increasing accuracy as technology advanced and improved, but there was no mechanism to collect biological data from the driver during a race. hitoe wear makes it possible to collect such driver data during a race. We are working to provide this biological data in real time during races, using our LTE network, and to achieve even higher performance by providing advice based on this data to the driver during the race.

In the future, we will utilize our networks, which are stable in the demanding, real racing environment, combined with the services, analytical technologies and expertise of all four companies to create new services that will enable drivers to perform in races with more comfort and efficiency.
