These types of controllers are garbage.
Not only are they laggy and not very precise... but even if they were dead on accurate... you have to hold the thing in the air for long periods of time.
Id love to see someone do a 100 lap race with their arms outstretched... let alone a simple few rounds of Virtua Racer, or other 2 to 5 min race romp.
I always laugh at all these ideas for air gesture / virtual controls. People are getting strain from physical devices that slide, or are rested upon. Imagine an 8hr work session where you had to keep waving your hands in the air! Let alone counting the time when you go home... and do more gesturing.
Not only that.. but why in the world would you want to replace batteries every month? And or if rechargeable.. buy all new batteries every year or so, when they fail to hold more than a 5min charge.
You also have a device, thats easily lost, and can get dropped / crushed / broken / stolen / and submersed in liquid via a vicious pack Gremlins.
Ohh, almost forgot the best part... The wireless receiver will eventually die. It will start off by losing packets, then a loss in functional range... intermittent disconnections... and finally... Kaput.
