4. Haptic Technology
Haptic Device
 The term ‘Haptic’ means sense of touch.
 It adds a sense of touch to the virtual environment.
 Haptic technology refers to the science of applying
sensation to human interaction with the computers.

5. What is Haptic device?
 Haptic device is mechanical device that mediate communication
between computer and the user.
Haptic Device
 Haptic devices are responsible for applying touch sensation and
control to interaction with virtual objects or virtual
environment.
 The user could feel the sensation of touching the virtual objects-
like textures, shape, edges or weight.
 The computer communicates sensation by using Haptic
interface.

 Haptic devices have one of the high levels of interaction.
Haptic Device
 It is used for input as well as output to a computer.
 Through the Haptic device user can get feedback in the form of
feel of touch.
 A user can receive sensational feedback from the computer as
output.

8. Senseg Tablet
Haptic Device
 It is a new generation of ‘Haptics’.
 It has a ‘Feel screen’ technology.
 A user can feel the different textures of
graphics on the flat surface of this
tablet.
 It provides tactile feedback.

How does the Sensege tablet work?
 The principal of attraction between
Haptic Device
electrical charges has been used.
 The electrode is activated by passing
electric current to the insulated
electrode.
 Electrostatic field based system
creates degree of fraction between
fingers and flat screen.

10. Simodant (Dental trainer)
 It is being used by UIC college of dentistry
to train the students.
Haptic Device
 It is a dental training devise.
 It is completely combination of virtual and
Haptic.
 It allows user to operate dental procedure
in realistic virtual environment while
receiving Haptics.
 Tasks are being done as if it had performed
on live patients.

11. Phantom Phantom had developed by Geomatic company.
Haptic Device
 It is a small robot arm with three revolute
joints each connected to the computer
 The tip of this devise has stylus which is
Haptic interface.
 The stylus has been held by the user.
 It provides force feedback- force and
directional force

12. Advantage
Safe:
Haptic Device
Realistic
experience:
12
• This technology allows you to see,
manipulate and feel the many
things so that it turns into a realistic
experience of learning.
• The user is in a virtual environment
while using Haptic devices.
