| Kurzbeschreibung |
Tactile sensors and their data processing are
very important in enabling robots to handle objects. With
information processing by biological organisms,
stochastic resonance (SR) can enhance sensitivity by
superimposing proper noise upon undetectable weak
signals to detect the target signal. To investigate the SR of
human tactile sensation and elucidate the mechanism of
tactile SR for the development of a new tactile sensor, we
performed a series of psychophysical experiments using
tangential vibration with 2.5‐mm and 8‐mm‐sized
stimulus points. We examined the difference threshold
(difference limen; DL) variation obtained from these
experiments to clarify which conditions of vibration
direction and stimulus size cause the strongest SR. The
experimental results show that neither normal nor
tangential DL is significantly affected by stimulus point
size. Moreover, tactile sensing precision is enhanced by
appropriate noise. The characteristics of SR, with normal
vibration obtained from our prior study is quite different
from that with tangential vibration. |
