Protection field
Personal space (or the lack of it) has always been a social problem around the world, especially in crowded places like China, and particularly in crowded spaces like the subway. This personal bubble, or protection field, in this case, is the perfect solution to both problems – the contagious Coronavirus and people’s lack of awareness of the concept of personal space.
It won’t come as a surprise if people will keep using this patent even after the Corona panic subsides, and what’s really surprising here is how come no one came up with personal bubble idea earlier. Either way, if you’re looking for a way to enjoy some personal space on the subway, look no further, the answer is before you.
