HAPTICS

What is haptics???

2

HAPTICS-a technology that adds sense of touch to virtual environment.

haptics interfaces allow the user to feel as well as to see virtual objects on a computer, and so we can give an illusion of touching surfaces, shaping virtual clay or moving objects around.

How it works???

5

There are two types of rendering algorithms:1) geometry dependent force rendering algorithm2) surface property dependent force rendering algorithm

6

.

PHANTOM

7

The phantom provides

single point, 3D force-feedback

to the user by stylus

attached to a moveable

arm.

.

8

CYBER GLOBE Cyber Glove can sense the postion and movement of the fingers and wrist.

CYBER GRASP: The Cyber Grasp is a full hand force-feedback exo skeleton device.

Medical Training Applications

9

Such training

systems make use of

phantom's force display

capabilities to let medical

trainies experience.

Collision Detection

10

Collision detection is a

fundamental problem in

computer animation,

physically based modeling,

geometric modeling and

robotics.

Prostrate Cancer

11

This technology is used in branchtherapy treatment.

Tactile Slip Display

12

Human fingers are able

to manipulate delicate objects

without either dropping and breaking

them.

Other Applications

13

MOBILE PHONES

samsung and motorola

supports haptics technology.

CARS

BMW 7 series makes use of

haptics technology.

Future Enhancements

14

The Virtual Braille

Display (VBD)

was created to investigate

the possibility of using the

lateral skin stretch

technology.

Haptic Torch for the Blind

15

The device, housed in a

torch, detects the distance

to objects.

More future vision

16

1.Holographic Interaction The feedback allows the user to interact

with a hologram and actually receive tactile response using acoustic radiation pressure

2.Medical Application Use of a central workstation from which

surgeons would perform operations in various locations; with machine setup and patient preparation performed by local nursing staff

3. Textile Industry User could study and feel the texture and

quality of materail during the sale of cloth through internet

Conclusion

17

The next important step towards realistically simulated environments that have been envisioned by science fiction authors.

Continued implementation of tactile devices to aid people with disabilities will advance further

Future generations of mobile devices and game console accessories will implement more haptic feedback

Still embryonic when compared to full fledged VR simulations
