如果您驾驶汽车，那么您很清楚盲点一直是驾驶员的问题。A cyclist or pedestrian might be under the impression that the driver of a car has seen them, but if they are overlapping the blind spots of the car, then the driver won’t be able to spot them, and it is this that causes a lot of accidents today.
大多数新车的盲点检测被称为盲点信息系统。传感器设备确定驾驶员无法发现的其他车辆，行人或骑自行车者的位置，然后向系统发出警告。这些警告可以是视觉，振动或可听见的。
遇到一个14岁的女孩Alaina Gassler，他来自宾夕法尼亚州西格罗夫。她提出了一项新的发明，该发明可用于解决盲点。Alaina参加了由科学和公众协会组织的中学生的Broadcom大师（数学，应用科学，技术和工程）竞争。
Her project was titled ‘Improving Automobile Safety by Removing Blind Spots.’ She explained the project by saying, ‘I did that by having a camera behind the a-pillar of a car, and the camera sent the video to a projector that projected the image onto the pillar, essentially making it invisible and making the driver see behind it.’ She has only made use of a camera, a 3D printer, a projector, and a retro-reflective fabric. The 3D printer was used to print a special part for helping to focus the project at close ranges, and the retro-reflective fabric was used for fixing the issues with the projection of the image on the interior frame since the image was blurry for other passengers in the car other than the driver.
Alaina Gassler能够在全国比赛中排名最高，她的出色发明能够赢得25,000美元的Samueli Foundation奖。
