The world's first computer mouse was made by Douglas Engelbart in 1964, it consisted of two gear-wheels positioned perpendicular to each other -- allowing movement on one axis. Ergonomic shape, great button placement -- and it's made of wood.
We have came a wee way since then!
We have used a variety of different mice since then, some of which are:
- Optical and laser mice - They make use of one or more light-emitting diodes (LEDs) and an imaging array of photodiodes to detect movement relative to the underlying surface, rather than internal moving parts as does a mechanical mouse.
- Inertial and gyroscopic mice - They do not require a surface to operate, inertial mice use a tuning fork or other accelerometer to detect rotary movement for every axis supported. The user requires only small wrist rotations to move the cursor, reducing user fatigue.
- 3D mice - These devices generally function through ultrasound and provide at least three degrees of freedom and was worn on a ring around a finger, which enabled the thumb to access three buttons. The mouse was tracked in three dimensions by a base station.
- Tactile mice - It contains a small actuator that made the mouse vibrate. Such a mouse can augment user-interfaces with haptic feedback, such as giving feedback when crossing a window boundary.
- Ergonomic mouse - It is designed to fit natural hand position and movements, to reduce discomfort and to avoid injuries such as carpal tunnel syndrome, arthritis and other repetitive strain injuries.
