Museum 3

what will the museum of the future be like?

Now here's something good - QR (quick response) Codes . Imagine visitors swiping their mobile phones across a bar-coded exhibit and downloading content to their mobile device. I know the Tech are doing something like this with their tech tags. We've also had discussions about this elsewhere on this site with Renae's blog post .

Seems to me that QR codes may be something acheivable for us. I still think that mobile technologies are one of the key trends we need to watch - I did a blog post in January about web trends which members may find worth re-visiting if you are so inclined!

This is the only place that I have read about QR codes, so I may be way out here, but by an engineering yardstick, this is a spastic technology. A 2 mega pixel photo (ie low resolution) contains 6 million bytes of information ie 6 million characters. If that can only produce 50 (or 250) characters of text, then let's not go there.
I think we should sit back and wait for something more sensible to come along. It will.
According to the Telstra promotional blurb, the code should be able to take up to 7000 digits and 4300 alphanumeric characters.

I have come across a QR blog which refers to the Japanese developer's (Denso-Wave) technical specs - apparently when printing or displaying a QR-Code there has to be a margin or “quiet zone” around the code in order to locate it and decode it properly. This “quiet zone” must have a minimum of 4 modules (a module has the size of the smallest square in a QR). Maybe it isn't necessary to reduce the density of the characters if there is a sufficient quiet zone around the code...my phone doesnt have the reader so I can't experiment.
Yeah that might need a different generator - I'll suss it out. Given that people are having difficulty with iPhones on more complex codes it may also be combination of generator and reader.
yeah . . . it is a mix of reader and generator. the more data in the code the higher resolution you need your reader to be able to pick up. if you are talking a cameraphone and a human hand holding it then there is no way the higher density codes will be readable. check out this code (from Wikipedia) which is a chunk of Lewis Caroll, and tell me your mobile phone camera could disambiguate it!

I've been exploring a less physically 'invasive' model of engaging high school student in commenting and gathering information in art museums in my postdoc research project http://www.intermedia.uio.no/display/Im2/Gidder The collaborating art museum would not allow QR codes mounted near the art!
Thanks for this. Your project sounds fascinating. I'll check out that book chapter and some of your papers - are any of them online??
