Screen With 180 Degree Field of View

emj writes to tell us project jDome has started actively soliciting consumer feedback and, of course, donations. They are currently promising to deliver their "180 degree FOV monitor" this year for a pricepoint of around $200. The videos and talk have been circulating for the last couple of weeks or so, but they have added a video of the supposed tech in action. Buyer beware, but I would love to see a couple of reviewers get ahold of this and let us know what the story is.

  1. Motion sickness? by LilGuy · · Score: 5, Interesting

    That looks like it would give me motion sickness for some reason. Maybe it's due to everything being stretched out of proportion and whenever you turn it's constantly shrinking and expanding. I don't know but that looked like a piece of crap to me.

  2. Re:Ya $200 bucks and... by twistedsymphony · · Score: 5, Interesting

    It depends on the game. I've been using a Projector as my main gaming screen for the last 7 years or so. My current setup is an Optoma HD-73 throwing on to a 94"x94" Dalite Glass Bead Pull-Down. I use an Xbox 360 for most of my gaming.

    some games become much easier to play, Fighting games, Racing Game, and Turn Based Role players. Other Games take some getting used to like FPSs and the Tony Hawk Series are nauseating at first due to the fast movement of the entire picture at once. Once you get used to it though, it's no different than playing on a normal screen.

    Some games do suffer though. For instance I do much worse when playing FPSs or DDR games on the projector because I have to move my eyes around the screen to see everything. On a normal screen 100% of the on screen activity is in my field of view 100% of the time. Also playing the Wii on the projector is difficult, for one you often find yourself casting shadows on the screen, and there are other issues associated with the IR pointer that make using that aspect of the controller difficult at best.

    Even still all Games are much more engaging and immersing on such a large screen IMO... I wouldn't trade my gaming setup for any alternative... Playing on a normal screen after the projector just seems cheesy by comparison.

  3. The issue is the projection by togofspookware · · Score: 5, Interesting

    Most 3D games won't let you set the FOV to 180 degrees, since it's impossible using flat (pinhole?) projection that most of them use. This choice of projection is also why things look so distorted at the edges of the screen with a high FOV, and is why objects that are near you appear larger than objects in front of you, even when they're the same distance away, among other visual quirks. In order to show such a wide angle (approaching 180 degrees or above), you'd need to use a projection that's not limited to showing objects on one side of a plane, such as fisheye projection. This isn't normally done because it's technically simpler to do 3D rendering when straight lines in the world correspond to straight lines on the screen (that's the simplified explaination).

    See this page for a visual comparison.
