Many Forms of Computer Interaction

A computing device takes many forms these days. Although the focus in business computing tends to be on the big 2 of UI and CLI, the wider reality involves more than text-based interfaces and graphical screens. Operations in a computer can be expressed multiple ways. The following are but a few:

  • Tactile feedback (i.e. vibrations or other physical oscillations)
  • Text-based interface (aka command-line, cli, and other names)
  • Sounds (whistles, chirps, and chimes among others), audio feedback and/or voice interaction
  • Direct neural interaction
  • Aerial, bodily, facial, or direct touch tactile gestures
  • Mechanical imprint (keyboard, stylus, mouse, and punch cards) and printed responses
  • Image recognition (i.e. input into computer through digital image scanning) using cameras/sensors
  • Graphical user interfaces

Mobile phones for example encompass many of these input/output capabilities in a practical format. A variety of devices will emerge over time based on the principle of computation that will incorporate more input/output dimensions in a holistic form. One day, a digital bracelet may come to embody such function and this digital bracelet or ring you wear on your finger or band worn on the head may allow you to apply computation more effortlessly. That is a big maybe, but the above modes of operation and more will be continuously pursued in a universal computation device.
