1. About QR Code The QR (Quick response) code is a type of 2D barcode created in Japan by Denso-Wave in 1994. The visual codes when photographed by a camera phone provide information or act as an URL and take the user to a particular web page. QR codes facilitate interaction using mobile devices and are often found in advertising, business cards, products and vending machines (Ley, 2007). This technology has also been used in innovative projects as a personal guidance system for individual with cognitive impairments (Chang et al., 2007); to collect students degree of comprehension (Fujimura and Doi, 2006) and to set up appointment reminders, medication reminders as well as to store demographic information of people chronically homeless (Gebrekristos et al., 2008). Mobile phones with built in cameras are very accessible and the visual tagging system can be easily implemented with QR code in order to provide numerous services. The only negative aspect is that it does require user interaction; it is not possible to provide an automatic context-aware feedback with QR codes as it is using GPS or RFID technologies.

2. QR Code Tutorial Equipment needed: - Computer - Mobile phone with built in camera 1. Download the QR Reader: You can download it directly to your mobile or to the computer and transfer it via Bluetooth or USB. There are several QR readers available you can check what works best with your mobile phone. Inigma On the computer go to: http://www.i-nigma.com On your mobile access: www.i-nigma.mobi Kaywa For both computer and mobile access: http://reader.kaywa.com 2D Sense (for the iPhone) Website: http://www.2dsense.com/page.aspx?id=matrix&sid=3 You can install it through iPhone App Store under the Productivity section or via iTunes.

2. After installing the QR Reader chosen on your mobile you can try to test it with this code: 3. Create your own mobile website. To create your mobile site you may use a website development tool such as Dreamweaver or you can use an on-line tool such as http://www.zinadoo.com/ . 4. Then generate your own code using the QR-code generator: http://www.i-nigma.com/personal/Create.asp http://qrcode.kaywa.com/ http://www.2dsense.com/2dsp CMIS - School of Computing, Mathematical and Information Sciences - University of Brighton 5
3. Inspirational Projects At the University of Bath QR Codes were projected during the lectures, appended to printouts and course instructions to deliver supporting materials in lectures and within administration, enabling students to download the presentation, provide feedback and evaluation (Roper and Ramsden, 2008). Another interesting and inspirational project, already mentioned in the introduction, uses QR codes to set up appointment reminders, medication reminders, as well as to store the demographic information of people experiencing homelessness. Gebbekristos et al. (2008) proposed a system that augments data entry methods utilized by homeless service agencies and provide a simple interface employing QR codes for configuring mobile phones to perform based functions for the chronically homeless.

4. Interactive Everywhere Example A botanical and spiritual mediascape of the Cockroft Zen Meditation garden was created using QR codes, and QR codes were also implemented in the interactive art gallery set up in the corridor of the Watts building (Floor 6) in addition to the RFID option. The garden example is composed by four codes. The first one presents users a brief introduction on meditation and the three others offer different types of meditation: breathing meditation, standing meditation and walking meditation. Users have to scan the code that will lead them to a webpage containing a brief explanation about the meditation chosen. The QR codes in the Barth exhibition lead users to the same data they would have access to with the RFID reader, however the QR code makes the information accessible to any user with a mobile phone and camera, not only the ones who have access to the project’s PDA and RFID reader.
