The MicroTactus is an instrument designed to detect signals arising from the interaction of a tip with soft or hard objects and to magnify them for haptic and auditory reproduction. An enhanced arthroscopic surgical probe was developed using an accelerometer and a custom-designed actuator for haptic feedback. Measurements were made to characterize the device and the results showed that numerous factors such as gripping method and gripping force influenced the system response in a complicated manner. The device was tested with the task of detecting surface defects of a cartilage-like material. Subjects were asked to detect the cuts of different depths under four conditions: no amplification, with haptic feedback, with sound feedback, and with passive touch. Both haptic and auditory feedback was found to significantly improve detection performance, which demonstrated that an enhanced arthroscopic probe provided useful information for the detection of small cuts in tissue-like materials.
