3D Demo
The 3D demo screen is an example application that illustrates how easy it is
to position and size an object for viewing using the MTCW. Use a single
finger on the touchpad to pan the object in either the X or Y direction. Drop
a second finger to rotate the object about the opposite axis. Use two fingers
in a pinching or un-pinching motion to move the object in the Z axis (toward
or away from the screen.) Spin two fingers about each other to rotate the
image in the z plane. In fact, using these simple gestures, all six degrees of
freedom of movement can be resolved.
Gestures that use the same number of fingers can be performed
simultaneously to quickly and efficiently position the object where it is
desired. Again, as in the 2D example, if the fingers are released from the
touchscreen during a gesture, the object will continue the gesture’s
movement with virtual momentum.
All of the gestures shown on the 2D screen application example can be
easily configured and recognized using the Instinct Gesture Recognition
Library. The gestures implemented and corresponding actions are only an
example of a typical 2D image application. The library is very flexible and
allows many different configurations for a variety of applications. The
Instinct Gesture Recognition Library is available license-free for Grayhill
customers. For further information about Instinct, please refer to
“Grayhill’s Instinct Gesture Recognition Library” section at the end of
