  title = {Mechanics of pseudo-haptics with computer mouse},
  abstract = {The haptic illusion based force feedback, known as pseudo-haptics, is used to simulate haptic explorations, such as stiffness, without using a force feedback device. There are many computer mouse-based pseudo-haptics work reported in the literature. However, none has explored the mechanics of the pseudo-haptics. The objective of this paper is to derive an analytical relation between the displacement of the mouse to that of a virtual spring assuming equal work done in both cases (mouse and virtual spring displacement) and experimentally validate their relation. A psychophysical experiment was conducted on eight subjects to discriminate the stiffness of two virtual springs using 2 Alternative Force Choice (AFC) discrimination task, Constant Stimuli method to measure Just Noticeable Difference (JND) for pseudo-stiffness. The mean pseudo-stiffness JND and average Weber fraction were calculated to be 14% and 9.54% respectively. The resulting JND and the Weber fraction from the experiment were comparable to that of the psychophysical parameters in the literature. Currently, this study simulates the haptic illusion for 1 DOF, however, it can be extended to 6 DOF.},
