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. 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:

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.
