I mentioned and linked to a news article, on my own website, about a piece of software that allows you to look through a phone's camera and see the realworld - with extra information....
...And thought I'd mention it here, too.
It allows you to add information about something, or somewhere - either as a note, a voice message, etc...
...Which someone else going to the same location and pointing their camera at the same thing will see.
It looks stupid, walking around and looking at everything though the phonescreen...
...But it is a good glimpse of the future, augmented reality overlayed on the realworld.
This software is only for the iPhone, but makes good use of the screen size and the touchscreen controls.
The article has a YouTube link showing it in use.
Quite amazing, actually !!
