4.4. Peripheral and I/O Hardware

New & Future Possibilities

Like all of computing, research is on-going for various kinds of input & output devices. Among the moving forces are the computer game and entertainment industries. Here, we quickly survey some new devices/techniques – sorry, no holodeck yet. There are lots of links that you can peruse. Special Education and Physical Therapy majors, along with others, may want to try the search to the right.

Input Devices

Gesture recognition

There are many ways to apply gesture input to computers. I will mention just a few recent developments:

Speech Recognition

Once considered the ultimate goal in "user friendly" interfaces, speech recognition now works pretty well. While, the search for the perfect interface continues, speech recognition is now common in mobile devices for texting (SMS), providing search keywords, and non-critical command applications.

Eye Tracking [src]

Eye tracking is the process of measuring either the point of gaze ("where we are looking") or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement. Eye tracking has been successfully used as an assistive technology for those unable to use regular input devices. And somewhat less succesfully in glasses.

Brain-Computer Interface [src]

A brain-computer interface (BCI), sometimes called a direct neural interface or a brain-machine interface, is a direct communication pathway between the brain and an external device. BCIs are often aimed at assisting, augmenting or repairing human cognitive or sensory-motor functions.

Output Devices

3D Screens

3D has become quite popular in the entertainment industry. Games have also moved into 3D. But what about 3D computer monitors? And, please, no glasses.

Haptic Interfaces

Haptic interfaces have to do with the sense of touch. Once again mobile phones and gaming are leading the way, at least in the commercial market.

3D Printing

Sending a FAX takes on a whole new meaning after you see what can be done with 3D printers.
