ABSTRACT
The ability of the user of a graphics system to interactively control the motions of 3-D objects enhances his or her spatial perception and comprehension of those objects. This paper describes several logical devices based on the tablet, each particularly suited to control some type of interactive manipulation of 2-D and 3-D objects in real time. The “turntable” and the “stirrer” convert rotary motion of the tablet pen or puck into values for one-axis rotational control; the “rack”, a two-axis device, is used for scaling control; for three-axis rotational control, the tablet-based three-axis trackball is particularly suited.

Inverse kinematics and rigid-body dynamics for a three rotational degrees of freedom parallel manipulator
Modeling and analysis of inverse kinematics and rigid-body dynamics for a three rotational degrees of freedom (DOF) parallel manipulator are conducted in this research. In the inverse kinematics model, the position, velocity, acceleration, jerk and ...
A study in interactive 3-D rotation using 2-D control devices
This paper describes and evaluates the design of four virtual controllers for use in rotating three-dimensional objects using the mouse. Three of four of these controllers are "new" in that they extend traditional direct manipulation techniques to a 3-D ...
