Vibro-tactile actuators Slide 6: COMPARISON Slide 7: HAPTIC INTERFACE First take away the drum Then use haptic interfaces to provide the same feel of hitting a drum Perception is still that of hitting a drum. Sound, vision, smell etc can then be added. Slide 8: Types of Haptic Slide 9: TOUCH TECHNOLOGY There are many types of haptic screen Resistive Surface acoustic wave (SAW) Strain gauge Optical imaging Dispersive signal technology Acoustic pulse recognition Slide 10: RESISTIVE Composed of 800 layers Two thin metallic electrically conductive and resistive layers Offer only 75% clarity Not affected by outside elements Slide 11: SURFACE ACOUSTIC WAVE(SWF) Ultrasonic waves that pass over the touch screen panel Portion of the wave is absorbed when panel is touched Damaged by outside elements Slide 12: CAPACITIVE Coated with indium tin oxide Conducts a continuous electrical current across the sensor Supports multi touch It only responds to finger contact Slide 13: STRAIN GAUGE Screen is spring-mounted Deflection when the screen is touched. Measure the Z-axis Slide 14: APPLICATIONS Slide 15: COMPUTER FOR BLIND PEOPLE Most blind computer users have a screen reader combined with synthetic speech and/or a Braille display Access to text on the screen, but not to the graphics Slide 16: Research Process Can feel objects Friction, springiness, damping, inertia Slide 17: Mobile User-Interface Through Touch Touch screen presses Keypad/control Scrolling Dialing cues Haptic Signature Slide 18: IN MEDICAL 3DVirtual Reality Unlimited practicing Users can “feel” and use real tools Instant feedback Slide 19: CONCLUSION It increases the bandwidth of human-computer interaction, and reduces the cost of the entire product development cycle Queries : Queries Slide 21: Thank You You do not have the permission to view this presentation.
