Umbrellaser / Project of Umbrella


There is water left on the ground usually in rainy days. In the darkness pedestrians often step on the water even using a flashlight. Using umbrellaser can solve this problem. Its appearance is similar to an ordinary folding umbrella, and a laser transmitter is in its handle. It can project a red laser grid on the ground. The grid on puddles is different from it on the ground. Pedestrians notice it and avoid to treading water.
