Some people can think using new technology gives them unfair advantage in achieving originality. While it holds some truth, what they are missing is that rationale or justifying the new technology which usually has some critical weakness and high price tag is very important and hardest to achieve.
One example to show this in my career was personal area network by near-field intra-body signaling. Simply speaking it means using your body as a conducting wire for communication between any device on your body. When asked about its potential application, exchanging address card by shaking hands was proposed. At first it seemed cool. But soon it seemed apparent that with the wireless technology so ubiquitous, it does not justify the use of novel technology. Actually it was awarded "Loser technology 2005 by spectrum magazine".
I happened to be assigned to this research at my institute. I had very hard time developing the application. At first I focused at the security aspects of it. Because relative small amount of electromagnetic filed is radiated in space, it is a little harder to intercept. But it could not justify the other disadvantage like short distance and mandatory skin contact. I still remember arguing with my boss about the application. I even declared it is useless technology with no adequate application. The revelation came suddenly. We touch what we are interested at. Touch means the attention. With so many devices waiting to serve our needs, the hardest part is how machine knows what I want now. And touching with data communication capability can give the clue about user's intention very naturally. Viola suddenly I can publish the work to the SIGCHI 2005 at Montreal. At the presentation, I received generous compliment from prof. Ishi Hiroshi from MIT media lab. It was one of my proudest moment.
