【正文】 old Katherine Wu is too young to have experienced this situation firsthand. However, she noticed how difficult it was for her dad to remain awake while driving back from their family vacations in Florida to their home in Maryland. Her mom had to talk to her dad all the way. “ So I created a tool that can be used instead of my mum talking to my dad to make sure he stays awake and is safe,” she says. Her invention, “Drivers’ Companion”, can notice driver sleepiness and warn the driver if he or she is too tired to be on the road. The user wears a headset , which sends information about the driver’s brain waves to a tiny puter. The puter can be placed in front of the driver. The system then gives warnings, if needed. As the driver bees sleepier, red color will be shown to warn him or her. The driver will also hear messages warning him to get off the road. The machine can say, “ You’re tired. Please take a break.” After sending her invention to the 2021 Discovery Education 3M Young Scientist Challenge, Wu was chosen as a finalist and was able to work with Dr. Jess Miller, who is a product development specialist. “ He helped me understand how important it is to make sure that my invention worked for the people who were using it and that it was userfriendly,” Wu says. As a young scientist, Wu has some advice for other students of her age: I would like to tell them that they should choose something they’re interested in. So they will be willing to spend more time on it and enjoy working on it more. Also, when there’s difficulty, they should just continue working hard because they’ll get over it” 25.
