주요내용: A Human-like Neural Tactile Sensing and Perception System
The human finger is the most sensitive tactile sensor, and the engineering realization of human tactile perception mechanism is a key technology of the future virtual reality world in which the tactile sense is synchronized. Human skin can detect physical stimuli including pressure and vibration sensitively and selectively through different types of cutaneous mechanoreceptors. In biological sensory systems, tactile stimuli are converted to action potentials through somatosensory transduction and the resulting signals are transmitted via afferent nerves. While slow adaptive (SA) mechanoreceptors generate voltage spikes in different rates and patterns depending on the strength of the sustained stimulus such as static pressure, fast adaptive (FA) mechanoreceptors generate most voltage spikes at initial contact and final release of physical stimuli due to their vibration-sensitive characteristics. These signals are delivered separately, and then integrated for multi-level information on tactile perception in the brain. There have been attempts to mimic the complex human tactile perception systems and implement them engineeringly, however, constructing such systems with human-like capabilities remains challenging. In this talk, I will introduce a method for designing a tactile sensor that mimics the function of human tactile mechanoreceptors and discuss a core idea for mechanically or electrically stimulating the skin to deliver realistic tactile information to the central nervous system. Finally, I will suggest that authoring tactile signals for each object is essential for implementing tactile interfaces in electronic communication devices.
