      Absolutely. I use a space-mouse at work (VR), but I guess relatively few people on slashdot know about them?

      You don't move it around like a regular mouse, rather you hold the hockey-puck sized control in your hand and push/pull it _gently_ in one of 3 directions. Being able to twist the puck gives you the other 3 degrees of freedom.

      The device is sprung and returns to center when you let go. The total movement of the puck is only about a centimetre (0.393700787 inches ;) in any direction.

      When you're used to using a normal mouse, it takes a while to get the feel of the relatively sensitive spacemouse, but since your hand remains stationary on the desk while using it, it's not tiring.

      Drawbacks: Cost - the things are EXPENSIVE! Also I doubt it would totally replace a normal mouse - with the speed turned up high it wouldn't be accurate enough for fine tasks, and with the speed lower it'd take you forever to get from one side of the screen to the other. The space mouse is intended to manipulate models in 3D space.

    Firstly, It quite simply doesn't make sense. Mice don't fly unless you throw them. This cognitive dissonance causes users considerable problems. We solved this quire easily by replacing the "mouse" with a "bat".

    Secondly, it creates arm ache. Holding the bat up for several hours just isn't possible. This was solved by the simple and rather crude device of a counterweighted piece of string on a pully on the ceiling. Of course, this isn't goinf to be suitable for a home user.

  • What you need is to put the ring on your finger, then get one of those laser-pointer mice and hold it: now you get:

    3d position of your hand.
    2d attitude of your hand (pitch and yaw).
    2 or 3 buttons.

    Now let's pretend you have a device like this that's light enough that you can wear it like a glove (no Nintendo jokes, please) and it's wireless. Add "roll" input and implement the buttons using something like midi drumsticks based on finger movements.

    Now, what's the user interface for this going to look like?

    Let's avoid the gorilla-arm problem by making a state change when you rest your hand on the table. On the table it acts like a mouse, except you're not holding a mouse you're just moving your hand or finger on the desktop and tapping it to click.

    So, if you're used to a mouse, you can use it like a mouse.

    Next, add gestures. Thumb and forefinger together and you're dragging. Curl your fingers into a fist and you just cut (grabbed) what you selected. Open your hand wide and you paste (drop).

    Now, move your hand off the desktop. A couple of inches away and you shift to 3d mode. Gestures work the same way, but now you can drag windows forward and back as well as up and down.

    Next, move your hand near the actual screen. Now it works like a light-pen with gestures, so you really can move that window out of the way by reaching up and dragging it. Why, you could even apply virtual white-out on your monitor!

    Finally, curl your fingers around like you're pointing at something. Now you're using a virtual laser-pointer... the mouse moves wherever your finger is pointing at. This extends the "light pen" mode back away from the screen, so you can rest your hand on the desk without breaking that metaphor.

    I'm sure that not all of these modes will end up being useful, but it wouldn't take much of a change in our existing user interfaces to find something that would work better than the mice we use now.

      • Cameras are one way. Ultrasound ranging is another: put three microphones just about anywhere around the workspace and a transmitter on the glove. Or three or four transducers and let the glove calculate its position using GPS techniques (the transducers can figure out their own geometry the same way).

        The glove itself can be low-key that way, more like an Isotoner than a Power Glove.

    The Spaceball [alsos.com] is specifically designed for 3D manipulation. You can push/pull the ball in 6 directions, and twist it in another 3 axis. You don't physically move the ball around in 3D space, it's more like a 3D-enabled trackpoint [google.com].
  • I worked one of these for use with a 3D visualization system some time ago. The problem is that it is very difficult to do precision selection of the data - not precision movement of the mouse.

    As other posters have aluded to, eventually you will get extreme muscle fatigue and want to hit something. At least, that's what I found. There was also a version that didn't rely on anything besides calculating arcs on the mouse and standard input.

    The ultimate 3D input device has already been invented, it's the Spa

    Logitech had a '3d' mouse back around, oh, 1995 or so. It had a stationary base and a mouse shaped handle. The whole thing moved in an XY space, and you could roll-pitch-yaw the handle. It 'emulated a mouse' so that you could use it to replace one - or so the box said.

    The REAL end result was hand pain the likse if which you've never seen. I had it back in the box and returned to the store in under 30 minutes.

    The desktop is a 2D environment. There is no need for a 3D mouse. If a 3D desktop environment actually catches on, then people will need a 3D mouse. Until then, it's a novelty.
  • Some people shouting here that it would take a 3d gui to use a 3d mouse. Others telling that thanx to the scroll wheel we already have 3d mice.

    I guess both are true. The 3d gui's that are designed (for general use) right now are probably all designed with our '3d' scroll wheel mice, as the adoption of the gui will be more likely (and much quicker) if people won't need a new pointing device just to try the gui.

    That's the problem with innovations. If you're not slightely backwards compatible, it will be ver
  • I'm surprised nobody has mentioned the Phantom [sensable.com] devices. They would work better than any of the devices mentioned in the article, and actually provide force-feedback. I've never used one, but I presume that if you let go of it, it probably could stay in the same position you left it in, so that wouldn't be an issue like it would with the other devices. The site also has 3D CAD applications that use it, and an SDK.
  • A reason.

    Look, just for the screw of it doesn't suffice.

    He has lots of other projects out there. My favorite is the mouse trap. I love the description...

    The body of the trap is made from a shortbread tin. Mice enter through a hole cut in the lower-right side of the tin. Once inside, they are forced to walk though a toilet paper tube to reach the bait. On the bottom of the tube is an infra-red LED which is aimed at a photo transistor at the top. These components are taken from the write-protect sensors of a 5.25" disk drive.

    All I need is a hypersurface to rest it on.
  • I prefer the WASD keys and a 2D mouse for moving about the digital ether. A step up from there is a joystick and a good sized track ball. While working at Midway games I got to mess with all kinds of 3d input devices. A few accellerometers can make a pretty cool/accurate input device.
  • I see a lot of posters saying this would be useful for 3D work (a pretty obvious answer), and as a 3D animator I'm unsure as to how this would really help with the way things currently work. Using Maya as an example, Maya simulates 3D in 2D to display it on the screen, and its current workflow is based entirely upon its 2D-manipulating-3D nature. Unless this approach was made radically different, there would be no difference in the process really except in the way objects translate; however then you run in

  • Anyone else remember this [nifty.com] from Logitech a while back? I remember Sierra Online was trying to hawk it in their product catalog (disguised as a games magazine) bundled with their games back in the mid-90s, when FPS games were just starting to take off.

    Found a review of it here [deadmedia.org].

    Apparently, Logitech even made a second, newer version, as seen here [3dgamers.com]. I had the original, I thought it sucked.

  • I'm thinking I'm going to build one of these. I think one could eliminate the pully slippage problem and aleviate the need for weights with the use of a simple coil spring attached to the pully arm and a spool for the string to wind and unwind from.

  • It is really an upside-down version of a device that appeared in issue 13 (Jan/Feb 1994) of PCVR. The article was entitled "A Simple 3D Tracker" by Stefan Elsner. It utilised digital encoders and motors to provide tensioning on the lines. Four lines were ran from the four upper corners of a room from the motor/spool/sensor packages at the floor corners of the room (and over pulleys at the top corners), and down to a mount which had a sensor to measure yaw for an HMD. Pitch and roll of the head were done usi
