Abstract
The system overlaying the stereoscopic images onto the haptic interface
is proposed. In order to develop the training systems based on virtual
reality medical doctors to experience medical treatments, it is important
to improve the reality that visual and haptic information are synchronized.
Our training system proposed in a previous paper for central venous injection
uses the stereoscopic glasses and the haptic interface. This system has
a palpation phase and an injection phase. During the injection phase, it
is important that the user can see 3D injector images and the stylus of
the haptic interface corresponding. In the proposed system, the user can
look down the images projected from the display and reflected on the half
mirror, and the haptic interface through the mirror. Using infrared LEDs
wirelessly attached to the stereoscopic glasses and the infrared camera
set under the display, the proposed system can show the 3D images considering
with the face position in real-time. This system can achieve higher reality
and more effectiveness than our conventional system. This system is evaluated
by the experienced medical doctor as effective one.
