Gaming Helmet Lets You Feel Headshots

What does five pounds of impact force feel like? The TN Games Website states that you can simulate what it would feel like by doing the following:
"Take a single roll of 50 pennies. Lay on the ground face up. Hold the role of pennies end on (up and down) 6 inches above your stomach, then release the roll and let the roll strike your stomach. That is what 5lb of force feels like."
The vest attaches to a Windows PC via a USB connection and it currently works with almost 30 games, such as Call of Duty 4, Crysis, and World of Warcraft, using the 3rd Space Game Driver Software and in some cases, game mods.

"The HTX Helmet is the next product in development for TN Games using its 3rd Space™ technology.
The HTX Helmet is worn in conjuction [sic] with the 3rd Space™ Gaming Vest and delivers blows to the head when you are fired upon.
Feel bullets whizzing by your helmet or the impact of getting shot in the head.
The helmet will communicates [sic] with compatible games to give precise, 3 dimensionally accurate impacts where it happens, as it happens.
Release date 2009"
We're not sure what five pounds of force would feel like on our heads, as we were unwilling to try the experiment with the roll of pennies on our noggins. However, we suspect that the HTX Helmet probably won't use quite as much force as the vest does. The bigger question to ask, however, is that will anyone truly want to simulate the feeling of getting hit, kicked, or shot in the head? If there are any gamers out there who are seriously considering this product, we'd like to suggest to TN Games that it start working on a pair of impact-generating pants with air actuators positioned in the crotch cranked up to at least 10 pounds.
