Sony's GDC panel "Introducing the PlayStation Motion Controller was exactly that: An introduction to the newly named Move peripheral. David Coombes, Kirk Bender and Anton Mikhailov showcased a number of impressive tech demos, many of which demonstrated the Move's incredible precision and low latency. One of the most impressive demos showcased full body tracking using an on-screen body puppet, not unlike one of Project Natal's tech demos.

Body tracking is made possible by combining the Move and PS3's head tracking capability. According to the presentation, the PS3 can also detect faces, going so far as to identify individuals through face contour and feature detection. The software will be able to recognize gender, age, smiles and when eyes open and close.

Coombes explained that all the calculations necessary to handle image processing are done by the Cell CPU, which apparently excels at the doing floating point calculations. The raw data can be processed incredibly quickly by the PS3, taking "under a frame" to translate to a game experience. And while Mikhailov didn't reveal how much of the CPU's overall power the Move controller requires, he did reveal that the memory demands are truly "insignificant" -- 1-2 MB of system memory.

good news i mean they just released an extra 70 mb of ram right? and develepers where doing great before that (uncharted 2 killzone 2 etc) so this is good stuff :D the current demos arent so impressive but its pre beta stuff and the technology is solid so im expecting great things in the comming year

Seems that Sony will have by far the upper hand in terms of graphics when it comes to motion controlled games. Think that move probably will be integrated in the OS and the processing will be done by the 7th SPE which is not released for the developers. So Move probably wont take away performance from the games at all.

System Memory or RAM ?

good...it would be a B if it took up some crazy number of memory

I'd say Ram since it would be an ongoing application but I'm not 100% sure.

Yep pretty sure it's RAM

of course they mean ram with the term "system memory"

Move is totally blowing everything else away. This means it is a non factor for developers as far as performance goes. They can focus fully on how to implement it new advanced ways, and still continue to set the bar in visuals. Kotaku is saying that the Sub Controller has Gyros, and accelerameters, so basically it will be like having a Wiimote in one hand with analog, and 1:1 tracking in the other. Additionally, they will be able to use vioce, and facial recognition, and they have full body tracking similar to Natal, all of which was demoed to devs today.

hmm what sony it's going to do with move it's what they did nintendo in the ps1 era.
they are creating a system with friend SKU for third party trying to steal the thunder.
