"THIS IS SO COOL when can i get one ebay?"

"This looks exciting! I am pleased that research in this area is moving forward. I wonder how the architecture could be advanced to mimic changes in elevation. "

"Great idea, this has been fantasized about for so long, but noone has had the initiative to actually begin working on it, very nice! "

"Pretty cool"

"I think I thought about doing this when I was a young kid... even then I saw two major problems: 1) The floor is curved. No way around it. Joints in the floor would be worse. Only way I can think of to make this less noticeable is to make a huge sphere. 2) The sphere is too massive. This is exacerbated by the solution to problem 1. The user would have to accelorate/decelorate the sphere. Unless this process was assisted, it would be incredibly noticeable (think hamster rocking back and forth on a hamster wheel). Any such assistance would be very noticable as well, I should think. To lessen this you need to make the sphere as light as possible. The picture shows a sphere which I am guessing is around 2.5m in diameter and fairly heavy. No matter how you build it, though, its not going to feel quite right. A huge leap beyond our current systems, though."

"Saw this at PAX, not too bad, but the wireless joystick which aims the crosshairs is highly inaccurate. It seemed though that walking wasn't hard, but I did hear that one guy got disoriented and fell after trying to walk too fast..."

"Well it's nice to see someone actually built that thing. I've gone over that idea in my head many times, but never did like it because it doesn't actually simultate ground terrain. I have a few other ideas that would better suit VR than a hamster ball, most use hydrolics and a real-time linux kernel to detect and influence movement via valves and in some advanced designes even pumps are used. But of course money is nowhere to be found, therefore my idea is just that, an idea."

"What happens when you walk over the hole?
(A door piece is fitted into the 'hole' so the interior surface is smooth when you start using it. You need an entrance somewhere!

"Looks stupid and so unreal to be in."

"Nice, I want to play online FPS's on that! :-)"
(g4m3r 9/21/2005 5:49:13 PM)
"Hrmph. Seems to me the kind of dodging you'd do on a combat field or in a game like quake would be aufully hard to pull off in that thing without injury. Not to mention the potential for tripping. Still, a virutal hamster ball for a tactical RPG type game would be aufully cool or a MMORPG."
(Ty 9/21/2005 5:50:59 PM)
"its really cool"
(AAdil 9/21/2005 7:55:08 PM)
"not exactly a breakthrough, but still very nice. I would go with a larger sphere for less relative curvature of the floor, and then a sensor that would detect when both feet are touching the 'floor' at the same time to automatically apply an enertial brake assist. Lift one foot, no more brake, put feet down, you stop. simple."
(mikebw 9/21/2005 9:33:00 PM)
"I suppose you could get used to the round shape while walking, but it would be like walking up hill. Only gaming I could see use this right now is an RPG. I would say an MMORPG but I don't see people actually having this thing in their house, unless they convert a garage into a gaming room. FPS wouldn't be very realistic or safe with that design. Running jumping, ducking, and other moves such as those would be painfully dificult in such a contraption. Nice idea though. Oh yea, the wheels on the bottom look like you stole them off of a grocery cart."
( 9/21/2005 9:20:58 PM)
"Floor: Flexible, tough rubber/plastic skin over many bearings. Motor-assisted movement of said skin under feet in response to foot pressure. It'd be clumsy until we got it right, but it'd be flat."
(Tranthas 9/22/2005 1:47:42 AM)
"what about the hole there in the wall? isnt that gonna be a flaw in the walking process? or does it have a hatch or something?"
(Nathan Couzens 9/22/2005 2:43:37 AM)
"American Gladiators rings a bell"
(AT 9/22/2005 6:51:09 AM)
"innovative idea, but other posts have pointed out the flaws. its still good for ppl to think and try stuff out to find what works and what doesnt."

"would this be any good for coutner strike source"
(nigel 9/22/2005 9:35:25 AM)
"Your balance would be off because even though your think you are running, the balancing mechanisms in your ear will be whacked because you aren't actually moving. The only true VR will be a chip in your brain (or/and spinal chord) that can decifer your movements and give feedback. They already have VERY simple versions of this already, in paralysis victims. Though, who would go this far for gaming???"
(Ozzy 9/22/2005 5:58:21 PM)
"On the virtusphere(dot)com site there are videos, including of FPS type training and gaming and people walking, running, jumping and rolling. And there is no hole - it's a hatch."

"Congradulations on your sphere idea. As an inventor of a simular device that uses motorized weights to turn my sphere I was excited to see your idea. Don't worry there is no infringement. U.S.Patent #5,702,307 I have another virtual reality simulator that you might want to take a look at. My web site is at The site is being remodeled right now but the animations of how it works can still be seen. If you have any questions just give me a call."

"a hamster ball. I must have one."
(icbkr 9/23/2005 2:16:56 PM)
"what if you fall in the hole?"

"Neat thing - took a mouse ball and turned it inside out!"
(JLawson 9/27/2005 9:59:09 AM)
"will this thing be used for porno ?"

"Interestingly, the technology was developed in mid-1990s and by late 1990s was already functional (with support for Quake 2 and Unreal). But it can take a lot of time to find the investors and sign financing deals for Russian inventors. :("

"Thats a cool idea. The other day i read in popular mechanics of a artificial arms that could grabs sensible things like eggs without braking them because the person wearing the thing could feel things. I thought that this same concept could be used in a game simulator. In a virtual world where u could grab or touch things your body would not know the limits of anything because u cant feel whether u are holding something or your hand is going thru a wall. If in the real world u could wear some type of suit so that u could feel whats happening in the game or vise versa the sphere would be better. (Also there's a picture of a guy in the article with the artificial arm were it looks like there are some sensors hooked fromt he arm to the body. If u could use sensors to capture brain signals that go to different body limbs you wouldnt need a sphere, you wouldnt need to more at all maybe. You would just need thoughts. I guess thats more into the future.) Here's the website"
