I am trying to interface a Playstation Ascii Sphere (links/pictures) to my PC. They are currently $10 brand new in the original box.
Why it is on these forums:
Basically you need to control yourself in 3 dimensions if you can see in three dimensions. A head tracking device is good, but that is for the view, you need to be able to move and look independently for greater immersion (more like real life). This requires 6 degrees of freedom (3 dimensions movement, 3 dimensions rotation).
How it works:
Inside the ball is a mirrored leaf spring, an IR LED and an Optical Sensor for each axis.
The mirror bisects the light between the IR LED and optical resistor (changes value based on light).
The amount of light varies as the spring and mirror move.
You simply turn, push, pull, and rotate the sphere to get every imaginable 3D movement.
I have a Spacetec SpaceOrb and an Ascii Sphere (There are pictures of both in the second post. (click here) ).
The SpaceOrb has some problems, like lack of buttons and drivers. Also they were (are?) pretty expensive and many are worn out. I asked Richard ( http://www.debaser.force9.co.uk/ ) about his notes on communicating with the Agetec Ascii Sphere controller for the Playstation
I got a reply:
You can find the interface notes (native sphere mode only) in the third post (click here).I found my notes on the ascii sphere not that long ago, so you are in luck
I've attached what I came up with at the time. In native mode it looks like the motion was reported as 12 bits in each of the three axes, but I can't remember now how the extra 4 bits were used (and didn't make a note).
The notes basically explain what data is returned in each mode, but otherwise it acts as a normal playstation controller. Hopefully that usb adapter is flexible enough for you to write some code to handle this.
I think that the Ascii Sphere started life as a Windows game controller, not sure what the interface was originally.

Benefits:
- *The Playstation controller version is available new (unused) for a reasonable price
*It has many more buttons than any other game controller version of the Orb
*It is pretty comfortable.
*And . . . it doesn't seem like the data is encoded (unlike normal Spacetec products)
*Currently you can find the controllers for $10 at http://www.baysoftgames.com/psxas360sp.html
