Design and Fabrication of a Haptic Interface System For Interacting With Deformable Tissue Environments

    

Haptics-A New Paradigm for Human-Computer Interaction 

      A haptic interface is a kinesthetic link between a human operator and a virtual environment. It allows the user of the virtual reality system to "feel" objects in a virtual world.

      The aims of this study are to design and fabricate a Haptic Interface System (HIS) using an instrumented Joystick. The environment was computationally represented using V-realm, while the Simulink and MATLAB were used to interface the encoder and motor.
To illustrate the concepts we simulated navigation a simple direction and interacting with a passive tissue. The constitutions equation of the tissue used the axial deformation to set the force of generated by the motor.
The ability of HIS for distinguishing stiffness parameter between various tissues is demonstrated.
The HIS consists of mechanical and electronic components systems, also has utilized of Simulink and V-Realm Builder toolbox in MATLAB software for control design and graphical environment, respectively. For real-time process of the sensory information and motor control, real time windows target, another toolbox in MATLAB6.5 is used.
