The way I understand it, Immersion managed to get a patent on add tactile feedback of ANY sort to software. So that covers any kind of technology that could produce rumble as long as it is controlled by software.
This is why the article says "Now, it appears that Immersion is trying to force the issue and garner more revenue for its
exceptionally wide-ranging patentl"
EDIT: Nintendo just hasn't been sued, but that doesn't mean there technology doesn't fall under Immersions patent. Immersion waited a long time before suing anybody, and the first were Microsoft and Sony, as these were probably easier and more lucrative targets, as well as considered proper test-cases by lawyers. If Immersion is finished with Sony, then depending on the outcome, Nintendo might still be next.
Anyway, although there are good ways of using rumble, and the 360 shows that it can be improved to be used more effectively, for me the 6 degrees of freedom is much more interesting.
Reasons for me why that might impact vibration feedback:
1. to be able to use that effectively, you need a very light controller.
2. the batteries drain far too quick when using rumble on the 360s controller right now
3. precision is key ... I'm assuming and hoping that the PS3 controller is very, very precise, to the point where you could use it as a pointer almost. If that goes at the cost of rumble, it's worth it.
4. price ... sony needs to keep the controller price firmly under control. First of all, Immersion licence fees add to the cost. And that money goes indirectly to Microsoft. Also, it may be too costly to have everything sorted out properly, especially given the brief time-frame. They should probably already have started production, so they can't expect too many delays.
5. time ... as in 4, they may not have enough time left before production to sort all the extra issues out. In fact, drawing up licencing agreement with Immersion alone might already take too long.
Of course, you might try to also buy stock like Logitech and Microsoft and settle stuff that way, but again there might be too little time.
Suffice to say, the matter is complex, and there are no guarantees. At the same time, this may all just be tough negotiations going on between Sony and Immersion. If they can't agree on the price (which would include the settlement fee for the PS2), then they might as well call off the deal.
So in short, if you can have both, that would be fine. But if it comes at a price, it depends a lot on the actual price.
Sure, if we were talking tilt only, then losing rumble isn't worth it. But we're talking accelerometers also, and I'm very curious to see how precise they managed to get those. For instance, if I slowly lift the controller - will it detect only my initial movement, or will it detect my constant movement? And precise will it translate this?
If it is as precise as I hope, then there will be a *lot* of uses for this ...
I so wish I was a developer right now and my job was nothing else than discover interesting ways to use the new controller! I'm already holding the DS2 in my hand sometimes to see what would be possible. For instance I noticed that one hand can easily hold the controller, with the thumb controlling the analog stick and index finger using the R1 and R2 buttons. It feels a lot like holding a gun actually, with the R2 button feeling like pulling a trigger to boot.
Also I wonder if you were to provide the lowest points of the controller with mouse like smooth bits, would the accelerometer be precise enough to be used as a mouse?
Questions, Questions ...
Maybe I could ask if Guerilla needs a developer who focusses on the new controller exclusively ... ?
