QR codes in presentation - lessons from SMS edutxt event
I recently presented om some uses of SMS in e-learning. The focus was on what I'd term an "SMS (edutxt) plus" approach. Where I discussed some uses of SMS with QR codes, word clouds etc., (my usual stuff). If you are interested the slides are on SlideShare (http://www.slideshare.net/andyramsden/edutxt-glasgow-sept08-uni-of-bath-presentation).
What I would like to report on is I did try to use QR codes more strategically throughout my presentation. The types of activities that I used QR Codes to enable, included;
- access an available download of the presentation in powerpoint format.
- make my contact details available as a vCard which could be automatically added to their contacts. This was important as I was using the SMS inbound tool.
- provide all links to reports and web sites through out the presentation. The individual could then scan the QR code to add these (at a click of a button) to their web bookmarks.
- provide a pre-written SMS text message to allow the individual to subscribe to a SMS text alert.
There were a couple of people clicking away and I managed to chat to them afterwards. Some interesting results emerged. Firstly, the size (quarter of the slide) could be scanned when projected at the back of the large room. This was even with the very intensive codes (vCard). Secondly, there were a number of different devices in the room. It worked very differently, on the iPhone the codes could not be read. However, on the pocket pcs using QuickMark reader it worked perfectly. Interestingly, when I discussed with Matt Roper (Software Developer at Uni of Bath), his initial thoughts were that perhaps QuickMark didn't use the QR Code standard. This is an anxiety for users. We'll be looking it this when I present at the Mobile Learning event at the University of Bristol.
Also, next time, I'll get the feedback from those in the audience who accessed the QR codes during the presentation. I'm very interesting in finding out their thoughts how this technology might be used to enhance teaching, learning and administration.
Really good article. I have been following your blog for last 3 months. You
have good knowledge
on Mobile(cell phone) Industry and happenings. Please continue the good
work. Thank you.
Really good post. Thanks
QR Code is a matrix code (or two-dimensional bar code) created by Japanese
corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response",
as the creator intended the code to allow its contents to be decoded at
high speed. QR Codes are common in Japan where they are currently the most
popular type of two dimensional codes.
Although initially used for tracking parts in vehicle manufacturing, QR
Codes are now used in a much broader context, including both commercial
tracking applications and convenience-oriented applications aimed at mobile
phone users (known as mobile tagging). QR Codes storing addresses and URLs
may appear in magazines, on signs, buses, business cards or just about any
object that users might need information about. Users with a camera phone
equipped with the correct reader software can scan the image of the QR Code
causing the phone's browser to launch and redirect to the programmed URL.
