This application, brought to you by G-Speak reminds me of the blog post on gestural digital signage app showcased at CES. In fact, this application is very similar, not to the advertisement scene in Minority Report, but the OS Tom Cruise uses in catching precrimers. It's a very unique system. I find it very hard to believe, however, that such a system would replace current operating systems including keyboard and mouse. The "cool factor" is certainly there, but the practical side of me says, "so what." However, video game apps, digital signage systems, and other niche technologies could benefit greatly from this interactive application.
