This document discusses haptic technology, which adds the sense of touch to virtual objects. It begins by defining haptics and explaining how it allows virtual objects to seem real when touched. The document then covers the history of haptics, including early uses in aircraft controls and the Apple Watch. It describes how haptics combines tactile and kinesthetic information. Different types of haptic devices are presented, including gloves and tools that allow users to touch and feel virtual 2D and 3D objects. Limitations and applications of haptic technology are also summarized.

2. INTRODUCTION
 Haptics,is the technology od adding the
sensation of touch and feeling.
 when virtual objects are touched,they seem real
and tangible.
 haptic senses links to the bain’s sensing position
and movement of the body by means of sensory
nerves withinthe muscles and joints.

3. HAPTICS.....???
Derived rom greek word ‘Haptikos’ meaning
“ABLE TO COME INTO CONTACT WITH”.
 Haptics=touch=connection.
 touch is at the core of personal experience.
 of the five senses, touch is the most proficient,
the only one capable of simultaneous input and
output.

4. HISTORY OF HAPTICS
 One of the earliest applications of haptic
technology was in large aircraft that
use servomechanism systems to operate control
surfaces.
 In 2015 Apple started to sell a wrist watch which
included skin tap sensing of notifications and alerts
to mobile phone of the watch wearer.

6. HAPTIC INFORMATION
COMBINATION OF:-
 Tractile Information :
refer to the informatin acquired by the
sensor connected to the body.
 Kinesthetic Information:
refers to thr information acquired by
the sensors in the joints.

7. HAPTIC DEVICES
•Glove or pen-type devices that allow the user to “touch”
and manipulate 3-dimensional virtual objects
•Devices that allow users to “feel” textures of 2-
dimensional objects with a pen or mouse-type interface

11. Haptic application development via
the application builder

12. LIMITATIONS
 High cost involved.
 large weight and size of haptic devices.
 haptic iterfaces can only exert forces with
limited magnitude and not equally well in all
directions.
 haptic – rendering algorithms operate in
discrete time whereas user operate in continuous
time.

13. TYPES OF HAPTIC DEVICES
 VIRTUAL REALITY/TELEROBOTICS BASED DEVICES
• Exoskeletons and stationary devices.
• Gloves and wearable devices.
• Point sources and specific task devices.
• Locomotion
 FEEDBACK DEVICES
• Force feedback devices.
• Tactile display devices.
