Inconclusive and inconsistent results from existing haptic testing systems, e.g. for trackpads, which include rigidly mounted resistive load cells and accelerometers, prevent accurate results, especially in a high-volume production context.

Accordingly, an improved test probe for a haptic device configured for mounting on a robotic arm, comprises: a contact tip configured for contacting the haptic device; a sensor configured for measuring a threshold force of the piezoelectric actuator device, and an haptic characteristic, e.g. acceleration, of a resulting haptic response thereof at a same time and a same location; and a compliant element configured for enabling the sensor to move relative to the haptic device.

This disclosure relates to haptic stimulation and provides improved techniques for permitting an adult toy of one manufacturer to drive reactions of a second adult toy (or an accessory) of a potentially different manufacturer. In one embodiment, sensor data from a first toy is buffered and resampled at a constant data rate to generate a genericized data stream.

Techniques can further be applied for mitigating skew between the timing of these actions / reactions and linked audiovisual material, thereby providing for improved content and / or an improved experience.
