Abstract: We characterize the detection thresholds of subjects holding a stylus with a precision grasp for six principal modes of vibrotactile display: three orthogonal force directions and three orthogonal torque directions. Subjects are far more sensitive to torque signals about the shaft of the stylus than to torque signals orthogonal to it, subjects are less sensitive at low frequencies to force signals parallel to the shaft than to force signals orthogonal to it, and the thresholds for force and torque signals applied orthogonal to the shaft can be approximately equated by considering the reaction moment felt at the grasp point.
