물체 자동 추적을 위한 3D Mouse

1. Electromagnetic position and orientation trackers

3BALL

Features

-A electromagnetic sensor, mounted inside, provides accurate orientation

of 3BALL in 3D space.

-3D positioning/orientation input device that incorporates your hand and

body’s natural motion in interacting with 3D images.

-3BALL can be used as a pointing device merely by extending your index

finger. You can track or trace movements, as well as your gestures.

-3BALL’S flush-mount switch allows you to grasp it with a comfortable,

natural hand position and operate the switch with just a light touch.

-A non-obstructive switch provides both tactile and audible feedback for

positive actuation and control.

-Allows you to move light sources, view objects from different perspectives,

and more.

Specs

-Size : 2.235 inches in diameter (regulation billiard ball)

-Weight : 5 ounces (142g)

-DOF : 6

-Accuracy : .03  position / .15 degree orientation

Interface

-3BALL transfers data to the host computer over an RS-232C serial link in

your 3SPACE system.

-3BALL is available as an option for the FASTRAK and ISOTRAK II systems.

Price : US $1,000 –



STYLUS

Features

-The STYLUS houses the electromagnetic receiver and permits easy and

accurate capture of (x,y,z) coordinates of the object being digitized.

-The STYLUS is a pencil-like device with an integral switch that permits

you to quickly and accurately capture x,y and z coordinates of real

objects.

-The STYLUS includes a contoured switch with tactile feedback so you

know when you’ve captured each and every point. Just hold the STYLUS

tip on the point to be digitized, press the switch, and the exact tip positi-on is captured.

Specs

-Standard 6.8 inch length or an optional 3 inch length for digitizing inside objects.

-Cable lengths are 10 or 20 foot.

-Two STYLUS tips are available and exchangeable. A sharp nib for high accuracy needs, and a round nib for applications involving digitizing of the human body.

Interface

-STYLUS is available as an option for the FASTRAK and ISOTRAK II systems.

-STYLUS is a standard component of 3DRAW.



3DRAW & 3DRAW PRO

Features

-3DRAW uses a patented electromagnetic technology that precisely measures

the position and orientation of the stylus tip in 2D and 3D space.

-There’s no need to maintain a clear line-of-sight.

-Both 3DRAW tablets may be used in a slanted configuration as a conventional 2D tablet for digitizing intricate drawings and artwork. A flip of the legs is all it takes to convert it to a level work surface for 3D items to be digitized. Simply place the tip of the stylus on any point on the object's surface and depress either the integral stylus switch or the foot switch to record and transmit the coordinates to the host computer.

-Both system have a working volume of 12" x 18" x 12" to obtain the specified

accuracy. Larger objects can extend beyond this volume or can be digitized in

sections since the system allows you to change the object's position if

necessary.

-3DRAW PRO and 3DRAW both measure the stylus' orientation as well as the

tip position, permitting you to use the stylus to rotate or manipulate your

image dynamically, or move the light source in real-time.

Components

-Tablet : The table provides the digitizing surface for both 2D and 3D

applications and houses the electromagnetic field transmitter. With the front

legs folded up, the tablet rests at a convenient seven degree tilt for 2D

operation. By folding the front legs down, the tablet becomes a level platform

for 3D applications.

-System Electronics Unit (SEU) : Contains the hardware and software

necessary to generate the electromagnetic fields, compute the position and

orientation data and interface with a host computer via the RS-232C serial

port.

-Stylus : The stylus is a pencil-like device that contains the electromagnetic

receiver and an integral data capture switch.

-Foot Switch : Used as an alternative to the integral stylus switch for capturing

data points. It permits faster and easier digitizing and promotes greater stab- ility of the stylus positioning.
