I was in Louisville, KY over the weekend, staying in an upper floor of the Galt House hotel, which offers an excellent view of the Ohio River.  In the wee hours last night, I awoke for a bit. I noticed that outside my window, I could see the bright blue lighted sign of a large office building. But my eyesight isn’t what it used to be. I could see the sign, but no matter how much I squinted I couldn’t make out the name declared by the sign.

This bugged me — and when stuff nags at my mind, even weird minor stuff, I have a hard time getting back to sleep. The hotel room was dark, and my eyeglasses were out of reach. I didn’t feel like getting out of bed. But my cell phone was within reach, on the bedside table. (It’s my main alarm clock.)

So I grabbed my phone and snapped a quick photo of the building with the blue sign. Then, looking at the phone on my phone’s screen, I could easily read: Central Bank.

sign on top of their downtown Louisville, KY building.

This satisfied my nagging curiosity, kind of like scratching an itch. I was soon back to sleep.

It occurs to me that this is a potentially significant use of augmented reality enabled by mobile devices — and the only “app” I needed was the software controlling my phone’s camera!

Most AR apps I’ve seen are kinda gimmicky or not very compelling. For instance, seeing local coupon offers overlaid on a camera app (which Junaio does), or local tweets similarly overlaid, hasn’t really thrilled me.

But being able to compensate for poor vision or a lack of information about what things are? That’s useful.

Now if only someone could do a similar service for audio that would automatically filter out noise in a train or bus station to tell you what the hell those announcers are really saying…
