Nearly every driver has experienced that feeling of great tiredness,where it becomes almost impossible to stay awake at the wheel. 14-year-old Katherine Wu is too young to have experienced this situation firsthand. However slie noticed how difficult it was for her dad to remain awake while driving back from ?ieir femiiy 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 mom talking to my dad to make sure he stays awake and is safe,” she says.
Her inversion ,“Driver's Companion”，can notice driver sleepiness and warn the driver if he or she is too t?ed to be on the road.
The user wears a headset(耳机) ，which sends information about the driver' s brain waves (月凶电波) to a tiny computer. The computer can be placed in front of the driver. The 吵对撕(系统) then gives warnings,if needed. As the driver becomes 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 2014 Discovery Education 3M Young Scientist Challenge,Wu was chosen as a finalist and was able to work with Dr. Jesse Miller,who is a product development specialist.
“He helped me understand how important it IS to make sure that my invention wprked for the people who were using it and that it was user-friendly,” Wu says.
As a young scientist,Wu has some advice for other students of her age: ul would like to tell them that they should choose something they* re interested in. So they 11 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’ 11 get over it."
