"Where does the dancer end and the dance begin?"
Great Line for late coffee house discussions and also a fundamental question for new - possibly undiscovered - disciplines. If you are an animator, illustrator, dancer, game designer, film maker, video dude, or an all around artist - then the book's content and attractions are pretty obvious. But there is a LOT MORE...
This book is just a STARTING place for new MoCap related technology waves. If you are an engineer, an athlete, a medical researcher, a medical product developer, or are someone concerned about quality of life issues for an aging population, then you NEED to understand current MoCap technologies and how to use them.
If there are negative aspects - then its a "turn off" that the MoCap process is presented using (very) expensive tools and software. But that is how technology works: something revolutionary starts out expensive and is the province of a "chosen few" - like IT was in the '60s/70s. MoCap software and tools are going to get more affordable: FAST. (It will add some difficulty in absorbing the material if you are not familiar with these tools.)
In the 60s/70s, I wanted to play on the university computing system but the (then) High Gods of University Computing did not let "peon students" have unfettered access to the systems... Well... these days my 9 and 10 year old children do systems and IT maintenance. My last computer purchase was a $599, 4g DDR, Quad (2.1G) core PC that - I believe - would out perform the total of ALL COMPUTERS WORLDWIDE THAT EXISTED in 1970. Point is that MoCap systems cost will drop. The APPLICATIONS will explode - and you MUST start somewhere.....
You should buy this book... Get a sense of where things are headed.... In technology, you come in early - and then start to apply the concepts to an exploding sea of applications - far beyond the immediate artistic implementation. If you are going to techno surf - then this is a good place to start....
You may know all about the Wii... Motion Capture was also used, for example, in the last Olympics to analyze Olympian's bicycle motion - and then provide the DETAIL to make SUBSTANTIAL training improvements... You may be able to use those same MoCap systems as a consumer in the very near future.. the list of applications goes on and on...
As as systems designer, I get to see very early on how some technologies just diffuse everywhere.. MoCap is one of those core technologies that apply to robotics, medical/fitness systems, motion analysis, communications, or even the book's initial target application of entertainment.
