  3. 3. WHAT IS HAPTICS? Haptics is related to sense of touch which comes from the Greek word HAPTESTHAI for to grasp or to touch. Touch is the first language. From a very early age we become sensitive to the specific qualities of touch rather than its mere presence or absence.
  4. 4. Haptics promises to open this bottleneck by adding a new channel of communication using the sense of touch. Haptics expands the notion of bidirectional communication between humans and computers to include sensory feedback. Haptics = Touch = Connection
  5. 5. Touch screens of all types the ability to “touch back” with unmistakable confirmation.
  7. 7. Industrial & commercial systems
  8. 8. HISTORY One of the earliest forms of haptic devices is used in large modern aircraft that use servomechanism systems to operate control systems. Such systems tend to be "one-way" in that forces applied aerodynamically to the control surfaces are not perceived at the controls, with the missing normal forces simulated with springs and weights.
  9. 9. HOW IT WORKS? Haptics applications use specialized hardware to provide sensory feedback that simulates physical properties and forces. Haptic interfaces can take many forms; a common configuration uses separate mechanical linkages to connect a person’s fingers to a computer interface.
  11. 11. Tactile information refers the information acquired by the sensors which are actually connected to the skin of the human body with a particular reference to the spatial distribution of pressure, or more generally, tractions, across the contact area. For example when we handle flexible materials like fabric and paper, we sense the pressure variation across the fingertip. This is actually a sort of tactile information.
  12. 12. FUNCTIONS OF HAPTICS :How touch and its underlying brain functions work :- Haptic technology:- technology that interfaces with the user through the sense of touch. Haptic communication:- the means by which people and other animals communicate via touching.
  13. 13. Haptic perception:- the process of recognizing objects through touch. Haptic poetry:- a liminal art form combining characteristics of typography and sculpture.
  14. 14. HAPTICS COMMUNICATION Haptic communication is the means by which people and other animals communicate via touching.  It providing information about surfaces and textures. It is a component of nonverbal communication in interpersonal relationships, and vital in conveying physical intimacy.
  15. 15. Human babies have been observed to have enormous difficulty surviving if they do not possess a sense of touch, even if they retain sight and hearing.
  16. 16. In chimpanzees the sense of touch is highly developed. As new borns they see and hear poorly but cling strongly to their mothers. Heslin (1974) outlines the four haptic categories:  Functional/professional  Social/polite  Friendship/warmth  Love/intimacy
  17. 17. HAPTICS PERCEPTION Sometostati -onary Touch combining with skin surface. Recognizing the object.
  18. 18. HAPTICS POETRY  Combining the charcteristics of sculpture and typography to create the object.
  19. 19. HAPTIC TECHNOLOGY • Every applications use the haptic concepts directly or indirectly. • In this fig. in touchscreen cell, internally there are very small boxes. when we touch any button, it will sense that what we want. And it give it as a output.
  21. 21. A form of computing that offers “a natural way of interacting with information,” rather than the “traditional user interface.” Direct Interaction: The ability to "grab" digital information with hands - interacting with touch/gesture, not with a mouse or keyboard. Multi–Touch: The ability to recognize multiple points of contact at the same time, not just one (Ex. One finger, like with most touch screens), but dozens. Multi–User: The Surface’s screen is horizontal, allowing many people to come together around it and experience a “collaborative, face–to–face computing experience”. Object Recognition: Physical objects can be placed on the Surface’s screen to “trigger different types of digital responses” (Ex. cell phones, cameras, & glasses of wine). 22 Touch Screen
  22. 22. 3-D gaming  Disney Research, Pittsburg (DRP) has shown off a revolutionary technology called ‘Surround Haptics’ that can bring real life experience in video gaming and film watching.
  23. 23. HAPTIC DEVICES A haptic device is the one that provides a physical interface between the user and the virtual environment by means of a computer. This can be done through an input/output device that senses the body movement, such as joystick or data glove. By using haptic devices, the user can not only feed information to the computer but can also receive information from the computer in the form of a felt sensation on some part of the body. This is referred to as a haptic interface.

  27. 27. Proxemics is the study of the communicative aspects of space.
  28. 28. Territoriality is personal space we don't want others to invade. Lyman and Scott (1967) identify 3 types of territorial encroachments: Invasion Violation Contamination
  29. 29. Invasion INVASION is more all-encompassing and permanent. It is an attempt to take over another's territory. Violation VIOLATION involves the unwarranted use of another's territory. This may be done with the eyes, the voice or other sounds, or with the body.
  30. 30. Contamination CONTAMINATION is defiling another's territory, not by presence but what we leave behind.  Defense The 2 primary methods for territorial defense are: Prevention Reaction
  31. 31. If the prevention of territorial violations does not work, how do people react?
  32. 32. Reaction One response to invasion of our privacy is behavior that restores our privacy zone. This response accepts the invitation and cedes the territory.  Another response is the well-known elevator phenomenon, in which people are crowded more closely than they like, so everyone looks up or down as if to say “I’m not trying to intrude into your space.”  A third response is to challenge the invasion—to stand your ground and refuse to yield territory.
