  • I'm thinking this has other uses, such as feed it a wireframe graphic of anything you like (would be handy for architects) and out the other end comes a ready-made model of your building, object, or what-have-you.

    • Yes, rapid prototyping is extremely handy for architects (as well as engineers, et al) -- if you can afford it. A few schools sport this stuff (MIT), and there are different kinds, but sadly it's not within reach of most designers :(

    • A keyboard isn't left or right handed. And the only mouse I have ever used that is more geared toward righties is the MS intelli-mouse. But there are plenty of excellent mice not geared for either hand. The 5 button Compaq mouse I am using right now is perfectly symmetrical - as someone who is ambidextrous I always think about that before I buy a mouse.

        A keyboard isn't left or right handed.

        Sorry, but no. A keyboard is relatively easily useable by a left hander (such as myself). However, a standard keyboard layout does indeed show right handed bias - the position of the numeric keypad and arrow keys as an example.

        While it is perfectly possible to use those with your left hand, it isn't as organic as for a right hander, and using your right hand instead would result in a lack of speed and possibly errors, since this is a weaker hand.

          In this regard, I would say lefties have a benefit :)

          Yes, but qwerty is probably better for lefthanders than right handers (e, t, and a, for example, are the most frequent english letters and they all appear on the left side of a qwerty keyboard).

        When you have side buttons on a mouse meant for your thumb, they become extremely difficult to avoid/use with your pinky when grasping the mouse.
        If you get on a machine configured to use them its a nightmare.

        • From what you describe, it sounds as though the mouse maker (logitech) is certainly not the one "keeping [left-handers] down", but rather those who configure a computer to use those buttons. Blame where blame is due, but not elsewhere. Any completely symmetric mouse is exactly as well suited (from the point of view of mouse manufacturing) for left-handers as it is for right-handers.

      So why don't you learn to use a mouse with your right hand? While I'm not left handed, a friend of mine is and uses his mouse in his right hand. He types on the number pad with his right hand. Yet, he writes with his left and bowls with his left.

      I mean, I can't use the keypad on a controller (PS2, etc) with my right hand, but I'm sure I could learn it if I tried (or had a reason to).

      • Even without primitives, I bet you could get some pretty good stuff with way of viewing what you're doing, and using existing surfaces as moulds. Want a flat part? Take a book, secure it where you want it, then draw over the surface. I can imagine this being pretty intuitive, even more so if you can then use your futuristic goggle interface to pick up and move the drawn parts.

    I want to say this is lame -- look at those lopsided, asymmetrical forms, that bland whiteness! But on the other hand, there's something aesthetically pleasing about rounded, continuous, organic forms. Add to that, each piece is unique and "yours" in a way no furniture built from plans or in a certain style can ever be.

    Now, there are refinements to be made. For one, interpreting the motion-capture as spline curves, instead of simple smoothed collections of points as they apparently are doing now, would allow for easy tweaking of the design. It would also allow imposing some automated corrections on the form, like "shift the top of this three-legged table until the center of gravity is on a line perpendicular to the plane of the legs which intersects that plane at the geometric center of the triangle defined by the ends of the legs" (which is to say, "make this three-legged table as stable as possible").

    Or, "make all four legs of this chair coplanar in a plane parallel to the plane that best fits the seat, and make the geometric center of the seat lie on a line perpendicular to the plane of the ends of the legs that also contains the geometric center of the polygon defined by the ends of the legs" ("make the chair not wobbly and stable to sit on")

    This was the concept that propelled Autodesk into working on virtual reality in the 1980s. Drawing in 3D on a screen required (and still requires) a complex interface; gestures in 3D looked like a way to make it a freehand job.

    Didn't work. Humans can't draw with any degree of precision in 3D free space. Clay sculpting works because of tactile feedback; it's not a pure eye/hand thing. And drawing in 3D free space gets really tiring within minutes. Technically, you can get the hardware and software to work. But it's too hard on the users.

    So virtual reality CAD R&D was dropped.
