Transcripts

I'm guessing the reason you're watching

this video now at this moment is because

you've got an interesting human computer

interaction

[Music]

um however you know that doesn't perhaps

mean you know exactly what it is maybe

you've just said it sounds like a good

idea so what is human computer

interaction well it's got two sides to

it on one side there's an academic

discipline which is about studying the

way people interact with technology and

in particular obviously computer

technology nowadays because computers

are in virtually everything it's it's

quite hard sometimes to tell the

difference

um but then there's another side to it

which is the design discipline and I

think probably quite a lot of you

watching this video will be from a

design side you're interested in user

experience design in interaction design

and so the so one side for human

computer interaction is the academic

discipline and the other is the applied

design discipline which is about how do

you create interventions with technology

that make a difference to people so one

side is studying that computer

technology and how it has an impact on

people so the way in which it works and

the other is more about saying that how

do we practically change that academic

study that inter information we have

about the way people have work

into action The Two Of course interact

so on one hand the professional

experience informs the academic

discipline and you'll probably notice

that I use lots of examples some from my

own experience some from stories I know

about from elsewhere and I use those

from all sorts of times in order to

inform my general understanding

because it works the other way around

that that academic understand that more

generic understanding feeds back into

the design discipline so so if I

understand how people interact with

individual computers how people interact

together in a group when they're using

technology how people how environments

change the way people are if those

environments have technology in then

I'll be in a better position to be able

to design things effectively for them so

these two are are intermingled

So within if you want to understand

human computer interaction if you want

to be part of this you know what kind of

things would I like you to know about

and so what what would I hope you'd

learn from studying human computer

interaction well first of all is bear

facts um there's facts about the the

nature of computers there's facts about

the nature of of human psychology

physiology there's a whole range of

things social interactions

um so there's lots of facts about that

of course the fact is you can read in a

book and I've got my own textbook that I

produced on this and um and there are

many many others um also on the web

there's vast amounts of material so in

some sense the facts are easy to get and

you will get some of those now hopefully

um when I when I talk about human

computer interaction you get some of

those fats however perhaps there's other

things which are more important

um the second thing I hope I'd hope

you'd learn from human computer

interaction is about analysis it's about

looking at the situation and trying to

make sense of it what's going on there

because if you understand the situation

then you can apply the facts to the

situation so it's about analysis about

it picking some things apart picking the

problems that you're having a part or

picking the opportunities apart and then

of course once you've done that analysis

together with the facts and knowledge

from that you can then do a design job

so you can bring these things together

in order to synthesize them in order to

create something that will be a solution

to somebody's problem

um but perhaps more important illness

than all of that obviously you need the

knowledge side and you need the skills

and to do it but perhaps the most

important thing with you within human

computer interaction particularly if you

think of it in terms of moving on into

design is an attitude of mine an

attitude that focuses on people that

sees real users real situations as

Center place

um that is seeking to understand people

however different they are from you

um and to do things which are good for

them

um and make sense in their lives so

that's that's sort of what you know our

purpose is in a way particularly as

every move from the the sort of just

studying people to actually say how do

we design something for them so it's all

kinds of things might you want to know

about these and what sort of kind of

things I'll often talk about in this in

this context so one set of things is

about the basics of design you know so

this goes from sort of processes that

people use when they're doing design and

you may be using yourself to methods of

evaluation to understanding the nature

of Human Experience

um

undergirding that is sort of fundamental

and denial lying knowledge and theories

um and some of those particularly about

the human about human perception

cognition emotion but that also leaks

into the uh understands the way

computers work as well to the extent

that it's important from a from the

point of view of their interactions with

people

um and then from a sort of practical

point of view you also need to think

about and be aware of the issues that

happen when systems are implemented

again that's partly about the way

they're implemented in the computer but

also the way in which they get deployed

into the world and this will vary from

from place to place but sort of the

general principles of how you make sure

that this wonderful system that you

designed actually gets used by people in

the real world and makes a real

difference to me
