摘要

A haptic communication device includes an array of cutaneous actuators to generate haptic sensations corresponding to actuator signals received by the array. The haptic sensations include at least a first haptic sensation and a second haptic sensation. The array includes at least a first cutaneous actuator to begin generating the first haptic sensation at a first location on a body of a user at a first time. A second cutaneous actuator begins generating the second haptic sensation at a second location on the body of the user at a second time later than the first time.

To perform the calibration of subjective force and objective force as described above, a user wearing the adjustable harness 1228 may indicate, for each level of adjustment of the adjustable strap 1230, a level of subjective force due to the corresponding pressure sensor 1226 pressing against the forearm surface 1232. For each level of subjective force indicated, each pressure sensor 1226 indicates an objective level of force by, for example, a voltage amount output by the pressure sensor 1226 due to the force sensed by the pressure sensor 1226. This establishes, for each pressure sensor 1226, and thus for each location on the user's forearm corresponding to the location of the pressure sensor 1226, a relationship between objective force measured by the pressure sensor 1226 and the subjective level of force experienced by the user. As shown further below with reference to FIGS. 12C through 12F, such a relationship may be used to develop a calibration curve for the user and to calibrate haptic devices to generate haptic output that is calibrated in accordance with the user's sense of subjective force, such that all users experience a consistent level of subjective force for an intended level of haptic feedback.
