Having a library that automated the creation of qr codes with a space left for an icon would be really sweet (if I didn't mention that already several times :) For my specific use case, a bigger QR code isn’t generally so much of an issue since it’ll be shown full-screen on a TV display.

We talked about the idea of drawing around the image instead of doing what you see above and drawing over the top. If this was successful you would still have all the error correction, but would just have a slightly bigger QRcode (based on how much information you wanted the code to hold). Also to note, that the important parts of the code are the alignment points. If these get tampered with, reading the code becomes very difficult.

Do you have any idea if i can autogen QR codes yet also include an image, without lossyness? suggestions welcome here on in http://wiki.foaf-project.org/w/DanBri/ButtonsAPI OK I got an iphone app that talks 2-way to XMPP now, with a faked up remote control… so I’d like to revisit the qrcode piece.

I am looking at XMPP as a communications channel between personal EPGs on smartphones and media centres. Seems to work fine, but authentication / pairing is an issue. If a telly displayed a giant QR code full screen, I think phones might be able to scan the code, and subscribe to the tv. Maybe send an optional pin. Since a full screen QR is a bit harsh / ugly, I'd like to make it a happier and more distinctive display, eg. by embedding an image or shaping the outer edges to be rounded, eg like a button - http://buttons.foaf.tv/ Haven't found any libraries that make this easy yet though. Guess I should get on with testing the giant qrcode / iphone hookup before getting lost on this detail! Thanks for any thoughts... Nice work :)

I agree with you too about the 'badge' design. It seemed to serve a purpose when I first pushed the idea in my blog post, but I do see how it just adds clutter. Ultimately I don't think this is going to be 'solved', since I think the placement of the barcodes should be such that no branding or additional 'help' is necessary to draw attention to them. What I want to get to is the point where these barcodes are accepted as part of everyday life, then they can become just another object on the page. I print media though, until phone camera macro modes become better they're not going to be able to be as small as I've seen in Japanese media, so they're going to stand out a little too much for daily use.

This work stems off the fact the current encoder we have been using (http://qrcode.sourceforge.jp/) seems to possibly have a memory leak in it. This work so far is a kind of first pass, just understanding what a logos look like in QR Codes. In terms of 'designing' QR Codes, I don't personally like the badge ideas. I wasn't actually sure about the logo in the QR Code originally, until after playing I found it looked quite pleasant. Having to surround the code in more livery makes it more messy for me, especially when it comes to printing and viewing at small sizes. The BBC example works at all sizes because it keeps the pixels used to draw the logo at the same size as the ones used to draw the matrix. As soon as you surround the logo in text/images then unless they also match the resolution of the matrix, they don't seem to work. Thanks for you comments by the way :) @Duncan, I actually agree, and we have been starting to look at re-writing the encoder to draw around the logo therefore keeping the error correction in-tact.
