overwraith Posted June 18, 2015 Share Posted June 18, 2015 Ok, So I got a raspberry pi B+ version recently, and got an idea for a Raspberry pi powered Oculus rift/Land Warrior type device. I really don't know where to start, and was wondering if anybody would have any thoughts. In order to make some kind of virtual reality device I am thinking I would need a raspberry pi camera, a raspberry pi of the correct type, possibly A+ or something, I would need something to mill or 3d print the frames, and the part I have no idea how to make would be the actual display. I wear glasses, so making something like this would need some sort of internal lenses, or would need to compensate for my vision some how. I see plenty of tiny screens for the raspberry pi, but am doubtful that they would be very pleasant to look at that close to one's eye. Does anybody have any ideas? I would almost need a custom built screen or something. (would also need some sort of battery pack, but that shouldn't be too hard.) Putting the raspberry pi in a pocket or something and running cables to the glasses would be the optimum solution, but I think not practical for the camera cables. This is just something I was thinking about, since not all the hardware seems to exist I will probably abandon this thread if nobody has any ideas. On the same token you all might know more than me.

barry99705 Posted June 20, 2015 Share Posted June 20, 2015 Does the pi even have enough horsepower to run an oculus?? Quote Link to comment Share on other sites More sharing options...
overwraith Posted June 20, 2015 Author Share Posted June 20, 2015 (edited) I do not know, I was thinking of building an oculus, out of a pi, not plugging an oculus into the pi. It supports cameras, so I would think there would be enough processing for my purposes, and it also supports very tiny screens like the ones in cell phones, but my problem appears to be that there would probably not be one that is designed to be that close to somebody's face. The B+ has 512 MB of RAM. Some of the other versions have up to 1 GB, and varying processors. If it supports a camera though it would probably handle what I want to do with it. I have a very specific idea in mind, more like a HUD really. Another problem that might arise would be somehow figuring out how to support two screens or something. It is probably a bad idea. I just thought I would ask for input from the community. Edited June 20, 2015 by overwraith Quote Link to comment Share on other sites More sharing options...
barry99705 Posted June 21, 2015 Share Posted June 21, 2015 Ahh, well in that case, I think latency will be an issue. Even my cellphone has lag when panning the camera. The lag is what gives people motion sickness. Quote Link to comment Share on other sites More sharing options...
fugu Posted June 24, 2015 Share Posted June 24, 2015 When designing the frame, you might want to try to design it so you can wear your own glasses inside of it. That way it is more "portable" for other people. Quote Link to comment Share on other sites More sharing options...
overwraith Posted June 24, 2015 Author Share Posted June 24, 2015 I am just worried that those tiny screens aren't good for operating that close to the eye. This idea although interesting is probably sunk until somebody develops a purpose built screen. We already have issues with screens causing eye problems, and that close to one's eye the display would probably look distorted or way too close to visualize correctly.

cooper Posted June 24, 2015 Share Posted June 24, 2015 I'd say you need about 15cm distance between the eye and the screen. And at that distance it's going to need to be pretty high-res too. Quote Link to comment Share on other sites More sharing options...

That's why optics were invented. None of the current HMDs are that far from your eyes. Quote Link to comment Share on other sites More sharing options...
