INTRODUCTIONThis paper presents a new compact three-dimensional (3-D) input device.
Typical 2-D input devices, such as mouses or trackballs, can input movements
of two degrees of freedom (DoF) and cannot handle 3-D with six DoF at the
same time. The more programs, such as computer-aided design systems and
virtual reality systems, support 3-D presentation, the more a handy 3-D input
device has been required ( Balaguer and
Gobbetti, 1996) ( Vince 1995).The PolhemusTm magnetic position and orientation sensor, the LogitecTm
sonic sensor, and the SPACEBALLTM are well known devices. These 3-D input
devices can directly input 3-D movement and have a more natural interface than
2-D input devices. However, they have some problems. Magnetic sensors or
sonic sensors are influenced by environmental conditions and tire the operators
who hold them in the air. SPACEBALLTM solves this holding problem. But, it is
difficult to input spiral movement, which is composed of rotational and
translation movements. Mechanical link type devices have singular postures
where the number of device's DoF is reduced.Our aim is to produce a 3-D input device which can be used beside a
computer in daily life. A good 3-D manipulation interface must provide a
natural way to input 3-D motion as well as support an appropriate response. A
good 3-D pointing device should
|1. ||input 3-D motion in natural ways analogous to real life,|
|2. ||respond effectively in noisy environments,|
|3. ||change operation modes smoothly, and|
|4. ||provide feedback to the operator from the computer.|
