Computer Input Technologies

Introduction The interaction between humans and the machine is a relatively new science. When considering how the inputs to a computer started out, it is interesting to observe just how little has changed. For example, the QWERTY keyboard as part of the typewriter invented in the 1870s(2) far predates the concept of the modern digital computer as described by Alan Turing in 1936(3). Our tools to interact with our own machines have however been refined to be more convenient for the average user with interfaces such as optimised USB and layout studied for ergonomy. In recent years, input technologies have not only been improved but brand new ones have emerged like motion control for example. The future is bright for input technologies.
A Brief History of Input Technologies
The Mouse Input technologies for the consumer in digital computers really began in the 1950s, for example with the trackball, early ancestor of the ball mouse. Interestingly, the first prototype of this device used a bowling ball as the trackball which was suspended with air bearings(1). This entailed high mechanical and financial cost for such a structure, however the basic concept of using a trackball and rotation sensors to translate user movement to the computer was born. About a decade later, this design was miniaturised into a consumer product. The trackball has since disappeared from our personal computers and desks for the most part. However it is still used in various…
