Problem Statement
In rainy days, people often feel depressed. Isolated by their own umbrellas, they also feel lacking connections with others. How might we cheer up people in a fun way and help them connect in the gloomy days?
Brello umbrella allows its user to press a button and light up another person's umbrella in the vicinity. The other person can then "wink" back by pressing the button on his/her own umbrella. The playful, non-intrusive light effects will surprises and delight people. It will also help people connect with their friends or even strangers without stepping out of their ways in rainy days.
