Concept
Human-Computer Interface (HCI) is an umbrella term
encapsulating all aspects of non-invasive interaction between human user
and machine. The ultimate goal is to remove the obstacles between the
machine and the brain’s desire.
Traditional methods are being
challenged, with various alternatives at widely differing levels of
maturity.
HCI shifts the focus of technology away from purely
technological changes and towards human behaviour, the understanding of
which will be crucial to the success of any new means of interaction.
Trajectory
keyboards,
monitors, and mouses represent barriers between the brain and the
machine, and will be the first to change and then ultimately disappear.
To transport a sentence from a cognitive spark to a word processor and
then to check the integrity of that sentence requires much work in
between the sender and receiver. Removing any part of this process will
lead to near-instantaneous and error-reduced action. This notion can be
applied to any other task.
Speech recognition is a current
example of an interface that reduces input time, albeit with its own
adoption problems. Artificial Intelligence and emotion detection may
follow this lead.
Low-cost accelerometers (such as in the
iPhone), accurate satellite positioning, image recognition, and low-cost
network processing and storage are driving consumer HCI design. The
biggest recent innovation is the multi-touch sensor which will no doubt
make big changes in how we behave and interact with the machine.
In
the longer term, direct technological interfaces with the brain (if
accepted by users) will allow direct control via thought and will
unleash an entirely new world of technology to completely change the
human way of life.
