| Tactile paving |
Late realisation. I always wondered what those raised lumps in the subway were. I assumed they were some kind of design feature. Now I know! Tactile paving. Yay! Thank you Google.
And it makes me happy that our government here in HK has spent the money to help the visually impaired.

Today's Google Doodle honors Japanese inventor Seiichi Miyake, inventor of the "Tenji Block" in 1965, which made possible "tactile paving" to help the visually impaired navigate by detecting a series of bumps or raised lines in the pavement (you can see a video of its use and importance here). You will be familiar with these as they've been installed in many train and subway stations. [here]
