Hiroko Kato's journey of problem solving

My research journey began in 2005 with a Bachelor of Science with Honours. I started my Honours project simply because I considered it a step to get myself into PhD study. However, once I started the project, I found it much more challenging and interesting than my previous coursework. Since 2006, I have been involved in my PhD project that aims to develop a novel colour two dimensional (2D) barcode.

Through the Honours project, I have learned the importance of active learning, having control over the entire project, finding problems in the real world, doing research on the problems found, and managing my time and budget. For the first time, I published an IEEE conference paper, which allowed me to attend a conference held overseas. Attending the conference really broadened my horizons and allowed me to meet people outside ECU and network and learn new things from them. It was a virtuous circle that leads me to attain First Class Honours and to be selected as one of four finalists in the 2005 WAITTA (WA Information Technology and Telecommunications Awards) student project award. I then went on to win the ECU 2005 Faculty Medal and was awarded a 2006 Faculty International Postgraduate Scholarship.

The Honours project allowed me to establish basic knowledge about the barcode technology, possible applications, problems, and how to solve the problems and improve the technology. Identifying a promising solution to overcome the problems became the goal of my PhD project and resulted in the invention of Mobile Multi-Colour Composite (MMCC). Patent protection has been applied for the MMCC. My research findings will be published via additional conference papers, journal papers and a book (due in June 2009 by the Cambridge University press). Such experience and achievements have opened the door for me to become an active researcher.

Now I am completing my PhD research journey and would like to thank my supervisors: Dr Alfred Tan and Dr Douglas Chai. My work could never have been accomplished without their constant support and understanding.
