The schematic diagram of the technique with which the artificial arm
system senses mechanical stimuli and transfer these stimuli to the subject, so that
the subject experiences the stimuli as the corresponding somatic sensations
Fig. 4.62.
The slide volume which was used in our study in order to describe the
subjective magnitude of the evoked sensation
robot hand. There was also a good correlation between the pressure applied to
the pressure-conductive rubber of the robot hand and the subjective intensity
of the evoked sensations.
The upper part of Fig. 4.63 compares the changes with time in the pressure
applied to the finger (upper line) and the subjective changes in the intensity
of pressure sensations felt by the subjects.
On the other hand, the lower part of Fig. 4.63 shows the changes with
time in the pressure applied to the conductive rubber (upper line), and the
changes with time in the subjective intensity of the evoked sensation when
the pressure on the robot hand was transferred to the subject by the system.
