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



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



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





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 



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




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