Using Multiple Input Devices
Ava Fatah gen. Schieck · eCAADe proceedings · 2004
The field of computer graphics has developed significantly over the last decade. However, most current CAD systems support only the two most common input devices: a mouse and a keyboard. In addition to that few, if any, systems make it easy for the user or the programmer to add and use new input devices. People tend to use both hands to manipulate 3D real world objects; one hand is used to orient the object while the other hand is used to perform some operation on it. The same thing could be applied to computer modelling in the conceptual phase of the design process. Accordingly, the 3D object can be easily and intuitively changed through interactive manipulation of both hands. This paper investigates the manipulation and creation of free form geometries through the use of interactive interfaces with multiple input devices. It demonstrates that using multiple input devices can offer many opportunities for form generation resulting in visually rich forms. However, the experimental results demonstrated that regulations are needed to avoid developing inefficient two-handed interfaces.
