Haptic devices

  1. 1. Haptic Devices Compiled and presented by, Sonali Kuril 1 SNDT Women’s University 1/5/2014
  2. 2. Content Outline  Haptic technology  Haptic devices. Haptic Device  Types of the feedback.  Examples of Haptic device • Senseg tablet • Simodent • Phantom  Advantage  Draw back  Educational Implications 2 SNDT Women’s University 1/5/2014
  3. 3. Learning Objectives At the end of this webinar, you will be able to- Haptic Device  Describe the term Haptic Technology  State examples of Haptic devices  Define advantages and drawbacks of Haptic devices  Elaborate educational implications 3 SNDT Women’s University 1/5/2014
  4. 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. 4 SNDT Women’s University 1/5/2014
  5. 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. 5 SNDT Women’s University 1/5/2014
  6. 6. Continue…  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. 6 SNDT Women’s University 1/5/2014
  7. 7. Types of feedback  The users can get two types of feedback while interacting Haptic Device with the virtual environment. 7 SNDT Women’s University 1/5/2014
  8. 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. 8 SNDT Women’s University 1/5/2014
  9. 9. Continue… 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. 9 SNDT Women’s University 1/5/2014
  10. 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. 10 SNDT Women’s University 1/5/2014
  11. 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 11 SNDT Women’s University 1/5/2014
  12. 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. SNDT Women’s University 1/5/2014
  13. 13. Haptic Device Drawbacks 13 SNDT Women’s University 1/5/2014
  14. 14. Educational Implications SNDT Women’s University 1/5/2014
  15. 15. Training and education  It can be used to train people for the tasks where hands-eye Haptic Device coordination required.  Haptic devices are being used in the Military training. 15 SNDT Women’s University 1/5/2014
  16. 16. Continue…..  It is being used in surgical simulations and medical training. For Haptic Device instance flight simulation, dental simulation etc.  For teaching subjects like geography, history and science. 16 SNDT Women’s University 1/5/2014
  17. 17. Medical Haptic Device  Robotic surgery  To try new tools and Rehearsal 17 SNDT Women’s University 1/5/2014
