Another problem we had with the head tracking was that after using it for a little while, the “center” position would get offset. For instance, if you set up the center of the screen when your head was pointing straight in front of you while sitting in an upright position, a few minutes later it is likely that you will be staring at your left leg when the cursor is in the middle of the screen. Again, we don’t really know why this happens, but it is definitely a problem. Resetting the cursor to the center of the screen with the Z800 3DVisor Software Utility is quite easy, sure, but we don’t think such measures should be necessary.

Gaming with head tracking also poses a few problems. We tried for many hours trying to replicate our performance in some games. In order to make this experience as easy as possible, we played the game we were most familiar with, Counter-Strike 1.6. If posting a positive record in a server with head tracking is hard, then playing as well with the head tracking enabled as you would with a normal mouse/keyboard/monitor setup is totally impossible. After looking into possible reasons for this, we have concluded that the neck is just not nearly as fine tuned in terms of precision movements as the wrist/arm combination. Muscles in the neck, and believe us when we say we are pretty far out of our element here, are probably not as fast-twitch has muscles in the wrist, which also contributes to the difficulty.

Needless to say, we didn’t have the greatest experience with the head tracking feature. Not only was it tremendously difficult to aim at people in the first person shooter games we were playing, but we found ourselves getting a bit queasy after playing for about 20 minutes. To make sure it wasn’t just because we get motion sickness very easily, we had several other people, gamers and non-gamers alike, test the product to see if they got a little bit sick. They said they did, and a couple of them got kind of mad at us for it.

The best way to use the 3DVisor, in our opinion, is to use it with the head-tracking capability disabled. Simply put, it’s not the best feature to have in FPS games.
