| This thesis deals with the design, analysis, and construction of a Variable Friction Haptic Display (VFHD) based on the principle of squeeze films. The primary function of the device is texture synthesis. A user can interact with the VFHD and feel variable friction on the 1.5 X 2.25 inch 2-D surface. The squeeze film is generated by an array of 6 piezoelectric, Langevin actuators. The finger position is fedback via a passive, modified pantograph. The novel contribution of the work is the incorporation of finger position feedback into the control of the device. The VFHD is good at displaying sharp transitions in friction and can simulate many textures. |
