voice control has inherent lag.
That's a good point and I agree there is lag. There is, say, intrinsic lag, in the need to receive enough sound to reliably distinguish one "command" from another. Then there is the lag required by the computer to make that discernment.
The summary asked "what's next?" and I would think current processing limitations, the discernment part, could be mitigated by advancements in processing power and algorithms. We may not be there, yet, but I could foresee a time when we would.
As for the intrinsic lag (and to some extent the processing lag) one could "lead" one's shots. Nothing says I have to wait until the target is already under the cross hairs before I *start* saying my command. Much like a quarterback leads his receiver, only sonically.
NOTE: I am NOT suggesting this would replace existing controls, but rather could act as a *supplement* to those already provided.
Besides, every input has a delay between the time I conceive of what I want to do and the time where I've commanded the computer to do it. Trackballs, joysticks, mice, and keyboards all have some delay. I'm thinking that there are at least *some* cases where one can use an audio input to achieve one's goal faster than using only the currently available manual controls.
btw if you wanted you could without too much trouble configure your pc to press shoot button on saying pew pew. but you'd get your avatars head shot off.
With *current* hardware, yes. Again, I was thinking of the future where processing overhead delay could be lessened to the point where this would be practicable, and with "leading" the shot, vocally.
Further, this need not be limited to only firing a weapon. That was just a sample use case for the sake of discussion. See my other example of saying "one" or "seven" while playing Sudoku on my computer instead of having to find and select it from a menu. I'm sure there are others and I'd love to see the /. community comes up with as possibilities and applications.
Obviously, there are cases where this would not help. Fine, don't use it. But I would think there ARE cases where this could augment/enhance existing controls. Maybe not right now, but in the foreseeable future, yes. Especially when both hands are busy trying to do other things, already.
