In this system, users touch a CG object in the display with the proposed haptic device and feel force feedback
. Figure 12 shows system overview.
Participants of Group II were able to manipulate the virtual surgical tools by means of the haptic device but without receiving force feedback
, whereas participants of Group III did receive force feedback
during the manipulation of the virtual surgical tools.
The simple algorithm needs less calculating time and steps, which may affect the hand-controller's real-time capability, response frequency, and force feedback
(i) On master device 1, the force feedback
from the mobile robot is bigger than the feedback of master device 2; then the trainer has greater perception about the state of the mobile robot than about the command provided by the trainee.
1 (no)-5 (yes) Did you feel that the force feedback
of the Haptic program was helpful?
Thus, there are several possible applications of force feedback
during NMT, predominantly during plyometric exercises (Myer et al., 2008b), to teach the athlete how to modulate force production during takeoff and force absorption during landing.
Like all haptics systems, sensors in robot grippers and effectors deliver force feedback
through the handle of a controller.
This paper reports on the development of real-time force feedback
at the Palmer Center for Chiropractic Research, which provides clinicians with real time visual graphical feedback on the magnitude of forces at the contact hand of the DC on the participant's lumbar spine.
In some experimental conditions, visual force feedback
was also provided to the subject in the form of a bar graph (see Figure 1 and Section 2.5).
has become an increasingly valuable feature in the medical device market.
Using tactile force feedback
, the operator is able to feel the actual process forces as he or she manipulates the robot from the operator cab.
This paper puts forward a sine periodic force feedback
controller based on the periodic external force feedback
control strategy and analyzes the stability of control theory.
