TWO-COLUMN LEFT-BOUND REPORT*
NATURAL INTERFACE APPLICATIONSi
A major area of artificial intelligence
has the goal of creating a more
natural interface between human
and machine. Currently, computer
users are restricted in most instances
to using a mouse and keyboard for
input. For output, they must gaze at a
fairly static, two-dimensional screen.
Speakers are used forsound, and a
printer forhard copy.The user
interface consists of typing, pointing,
and clicking.New speech recognition
and natural-language technologies
promise to change that soon.
SPEECH RECOGNITION
One of the most immediately
applicable improvements comes in
the area of speech recognition.
Rather than typing information into
the computer, users can direct it with
voicecommands. A computer that
can take dictation and perform
requested actions is a real step
forwardin convenienceand
potential. Speech recognition has
developed rather slowly,mainly
because the typical PCdid not have
the necessary speed and capacity
until very recently.
NATURAL-LANGUAGE INTERFACE
Computers that are able to
communicate using spoken English,
Japanese, or any of the hundreds of
other languages currently in use
around the world, wouldcertainly be
helpful. In the not-so-distant future,
computers will most likely be able to
read, write, speak, and understand
many human languages. Language
translators already exist, and they
are getting better all the time.
Programmers can lookforward to a
human-language computer interface.
With better interfaces, programmers
may be able to describe whatthey
want using natural (human)
languages, rather than writing
programs in the highly restrictive
and rather alien programming
languages in use today. Natural-
language interfaces are an area of
artificial intelligence that is broader
in scope than simple speech
recognition. The goal is to have a
machine that can read a set of news
articles on any topic and understand
what it has read. Ideally,it couldthen
write its own report summarizing
what it has learned.
VIRTUAL REALITY
Virtual reality (VR) describes the
conceptof creating a realistic world
within the computer. Online games
with thousands of interacting players
already exist. In these games people
can take on a persona and move
2
about a virtual landscape,
adventuring and chatting with other
players. The quality of a virtual
reality system is typically
characterized in terms of its
immersiveness, whichmeasures how
real the simulated world feels and
how well it can make users accept
the simulated worldas their ownand
forget about reality. With each
passing year, systems are able to
provide increasing levels of
immersion. Called by some the
“ultimate in escapism,” VR is
becoming increasingly common—
and increasingly realistic.
MENTAL INTERFACE
Although still in the experimental
phase, a number of interfaces take
things a bit further than VR, and they
don’t require users to clicka mouse,
speak a word, or even lift a finger.
Mental interfaces use sensors
mounted around the skull to read the
alpha wavesgiven off by our brains.
Thinking of the color blue could be
used to move the mouse cursor to the
right, or thinking of the number
seven could move it to the left.The
computer measures brain activity
and interprets it as a command,
eliminating the need to physically
manipulate a mouse to movethe
screen cursor. While this technology
has obvious applications for assisting
people withdisabilities, military
researchers are also using it to
produce a superior form of interface
for pilots.
