A first in NASCAR history! Brainwave measurements during a race!? -Details of measurement data-
June 2024month7It was held in Sonoma, California onNASCAR Westseries(https://www.arcaracing.com/arca-menards-series-west/)This article is about the results of measuring the brainwaves of racers while driving the General Tire 200.
In this article, we will provide you with more details about the EEG data.
Brain wave measurement results
Koga's concentration level was scored based on his brainwaves recorded during the final race in SONOMA.
After comparing the race footage with Koga's memory later, the following results were confirmed.
result
- When doing laps at high speeds, I tended to maintain a high level of concentration.
- When the yellow flag was raised and the racers were driving slowly behind the leading safety car, their concentration tended to decrease, but once the yellow flag was lifted, their concentration tended to increase in preparation for the restart.
Details of each point ① to ⑥ are as follows:
① Immediately after the rolling start (15:33), the first yellow flag (15:37~15:49)
Shortly after the start of the race (15:40), a yellow flag was brought out due to a suspension part from car # 42 falling onto the race track near Turn 4.
On this occasion, there was a lapse in concentration whilst driving slowly behind the leading safety car.
② Normal operating hours (15:51-16:06)
I maintained a high level of concentration while completing laps at high speed.
3. Repeated yellow flags (16:07~15:31)
16:07 To Turn10 Spinned at # 71 A yellow flag was brought out due to an accident in which a vehicle went off the track onto the gravel and crashed into a wall.
Seeing that the car was returning to the pits splashing gear oil all over the place, Koga decided that it would take some time for the yellow flag to be lifted and decided to change tires.
Looking at the concentration score here, we can see that the score drops towards the pit stop, and then rises again after the pit stop.
16:20 About 13 Just when it seemed the 10-minute yellow flag had been lifted, 1 minutes later 16:21 There is another # 15 The tires came off the vehicle, Turn7 An accident occurred where the car rolled on the race track, causing the yellow flag to be shown again.
Here we can see that concentration drops again before rising again.
④4th Yellow Flag (16:41~16:50)
At Turn 8, car # 50 was battling with car # 32 for the inside when it went off the track and crashed into the wall, bringing out the fourth yellow flag of the day.
Along the way, car # 4 had to be towed away when it was unable to climb the uphill section of Turn 1, and the team's concentration fluctuated until the yellow flag was lifted at 16:50, about nine minutes later.
⑤5th Yellow Flag (16:41~16:50)
Car # 80 was unable to brake at Turn 7 and the safety crew had to go and retrieve it, resulting in the fifth yellow flag of the day.
You can see that concentration drops during the yellow flag, but then picks up again halfway through.
⑥Final yellow flag to goal (17:16~17:28)
Yellow flag was brought out after car # 50 went off the course.
When the yellow flag was lifted about nine minutes later at 17:25, the team's concentration, which had been declining, improved, and after some trouble including Koga's vehicle breakdown, they managed to reach the finish line.
You could see their concentration wane as they approached the goal.
Summary
As a result of measuring Koga's brainwaves during a NASCAR race, one of our company's challenging projects, we were able to obtain more data than we had expected.
Everyone involved was amazed, and Koga himself was surprised that the results matched up with his own intuition, and he looks forward to further use of the data.
This measurement can be considered a step towards successful experimentation, but we would like to use what we have learned to move forward with further data acquisition and analysis.

What is "objective content evaluation" based on brain waves?
I would like to visualize people's unconscious emotions and cognitive states based on brain waves.
I'm sure there are many things you don't know, so why not measure your brain waves and experience what it's like?
After the actual measurements, we will share examples of how AI has been used in our activities so far, so that we can better utilize AI using brain waves at our customers' sites.
We will support you from proposal to implementation and operation.
