3. INTRODUCTION

4. Introduction Define “hap tic “ as a technology that adds the sense of touch to virtual environments. Hap tics refer to senseing and manipulation through touch. The word comes from the Greek “haptesthai” meaning to touch Haptic Systems

5. How Does Haptics Work? Sensor(s) Actuator (motor) control circuitry One or more actuators that either vibrate or exert force Real-time algorithms (actuator control software, which we call a “player”) and a haptic effect library Application programming interface (API), and often a haptic effect authoring tool

6. Why Use Haptics? Haptics Digital Tablet CyberGlove Mouse Keyboard VelocityTorqueAngularorientationPressureForce3DPosition2D PositionTime

7. Haptic interaction

8. What is haptic interaction?  " A haptic interface is a force reflecting device which allows a user to touch, feel, manipulate, create and/or alter simulated 3D objects in a virtual environment"  haptic. (Adjective Grk: haptein) having to do with the sense of touch; tactile  haptics = touch, tactile, force-feedback, using force/resistance, texture, heat, vibration

9. What application areas are best suited to haptic input? medicine, for training, surgical simulation other risky/specialised areas, e.g. astronauts, mechanics education about complex objects, e.g. chemistry creative 3D work, e.g. modelling, product design interaction for disabled interaction in 3D and VR environments

10. What sorts of product are being produced? magnetic levitation interaction devices exoskeletal devices

11. the Phantom haptic interaction device the Pantograph

12. Important Bill Buxton “hand on=finger on” Not exploiting the interface to computing up with computeing power More 3D ad VR environments in games and elsewhere Demand for richer input and output possibilities

13. Advantages Reduction in low energy Increase in productivity and comfort Decreased learning times Large reduction in manipulation error

22. conclusion

24. Total Solution Scalability – HapticTouch technology can be applied to small and large surfaces and a wide range of form factors. Thin – our low profile design is the thinnest solution available. Ease of Integration – The active surfaces can often be integrated into your existing industrial design, resulting in minimal changes and fast time to market. Reliable – Our approach uses well understood materials and processes, so manufacturers can design systems for long life, even in the most hostile environments. Power Efficient – HapticTouch systems sip power with minimal impact to battery life. Fast Response Times – Surface response is virtually instantaneous, ensuring a compelling experience no matter how fast the interaction. Design Freedom – HapticTouch technology enables next generation designs that exceed user expectations. Keyboard/keypads can be credit card thin, easily cleanable and fully rugged. Touch screens and touch pads can deliver intuitive tactile feedback for a satisfying user experience. Appliances, automobiles, and industrial control systems can implement reliable, digital-sensing technology without sacrificing usability.
