Using the Phantom Omni Device
This chapter will introduce you to working with the Phantom Omni haptic device and the
physical limits of the device’s range of motion. It is important to understand these physical
limitations so that you do not inadvertently damage the device by forcing it past its
designed limits.
Working in 3D Space
We have become so accustomed to using a mouse to move around a computer monitor that
we don’t think twice as we move our hand around a desk to move the cursor on the
computer screen. But there was a time not long ago when this seemingly simple task was
not second nature; some even found it challenging and were often frustrated as they
learned. If you are new to working in 3D digital space and haptics, working with the
Phantom Omni device may take a little getting used to. Understanding where objects are
in 3D space may take some practice before you are able to move and manipulate objects
with ease and certainty. Be patient with yourself.
Physical Limits of the Device
The Phantom Omni device has six degrees of motion provided by six axis points. All the
degrees of motion have physical limits. When you reach one of these limits you will feel a
sudden stop; this is the mechanical stop designed into the device. Forcing the device past
any of these stops risks damaging the device.
Take some time to become more familiar with the location of the mechanical stops of the
Phantom Omni before using the device by moving the device through its full range of
motion at each axis point.
1 First make sure the device is not active; the inkwell should not be lit. If the inkwell is
lit, close any haptic applications you have open.
2 Grasp the stylus as you would a pen, with the free end of the stylus (the eraser end of
a pencil) pointing toward you and the point of the stylus (the end connected to the
arm) pointing toward the unit. Using the following illustration as a guide, gently move
the stylus in all directions to feel each mechanical stop.
