Touch Screens & Haptic Technologies

Snapshot_20131220_9

Haptics has been studied for decades. It is simply the science and philosophy of the sense of touch. Its also of worthy note that it is paralleled with computer automation. Its technology is drawn from jellyfish and worms sophisticated touch responses. Naturally, the Human hand (rich with receptors and nerves) has 27 bones 40 muscles, 22 joints and 22 degrees of freedom.

Machines and Robots have been developed in line with the above facts. In addition, Artificial Intelligence lab in MIT made a device that can feel a computer generated object. Do note that physical hand feedback is based on kinaesthetic & Tactile moves.

Examples of Applications of  Haptic Technologies:

 

  1. Phantom Interface from Sensible touch. This haptic technology is based on information displayed from several differing points. Well, you could say it displays information at a single point.touchscreen-3-placement
  2. CyberGrasp System: Communication availed from Immersion Cooperation. It is based on fitting a live object or feeling solid and other forms of matter virtually.
  3. Carnegie Mellion University. They made an interface that uses a powerful electromagnetic force to imitate a handle like a joystick immersed in a virtual environment. Its major feature is it’s not linked to physical connection of cables or sorts.
  4. Some would classify the evolution of Haptic Devices thus:
    1. Electromagnetic tech: vibratory motors, alert, voice call in a speaker,
    2. Touch Coordinate Specific Responses. Localized to position on screen.
    3. Touch coordinates customizable effects.
    4. Pressure Sensitivity

Further Applications of Haptic Technology can be found on:

  1. Electronic Displays
  2. Telecoms (Simulators)
  3. Video Games
  4. Personal Computers (PCs)
  5. Mobile Devices
  6. Virtual Reality
  7. Medicine

Futures of Haptics are: Holographic Interaction (feedback), Virtual Operations in Medicine.
