i never understood how the cybercarpet and cyberwalk knows which direction and speed you're trying to go to try to match it. can you please explain?

[superfluent]

@3zoozM Well, in fact nobody knows. Imagine a women in a shopping mall - you can never guess in which direction the next geat offer will be (funny example but with some truth in it). With regard to the limitations in acceleration which the human body can be exposed to, a certain size is requested. If you respond with immediate compensation it would feel like on ice. That's why the big cyberwalk has a 4.5x4.5m active area (see my other videos)

Wouldn't it be more practical to walk on bottoms of an upside-down pair of robotic legs? That way you can simulate stairs and uneven terrain?

[superfluent]

It would be, but safety issues are severe fot this kind of design. We thought about it, but the risk to chop somebodys foot off is not neglegible...

This is truly awesome! If this becomes an affordable technology, it could make virtual reality worlds a LOT more interesting.

Hope a model can be built that can withstand running and jumping.

I think the big question is: What happens if you get your hair in it?

[superfluent]

Hair is not such an issue, if you manage to get hair near the platform which is long enough, some single hairs can be ripped off. Anyway, make sure that you keep your head up :-)

@stevenazari The world record for fastest recorded human speed is only 4.5x the speed of the cyberwalk prototype in this video. To allow for such speeds, a more reasonable sized platform (larger, preferably diameter of over 4 meters) and/or higher power motors are required.

there are no pressure points, movement is tracked via a computer camera.

[roidroid]

@3zoozM it has a camera connected to a PC, looking down on whole platform. So it can see how far away from the center of the platform you are. It then controls the motors to try to get you back into the center (with movements as smooth as it can manage).

I actually have several ideas for this and the VR world... I wish I could speak to the colleges developing this to see if my ideas are tangible or impossible.... >.>

[stevenazari]

Hi there - loving the work you guys are doing, what about if you tread carefully or take a big leap from one point to another? is it also pressure points that are being considered or just tracking movement per ball?

keep up the awesome work

[racovalerio]

more expensive.

so what wrong with the real world? i.e walking and shit
