- During our July Virtual UX Conference,
Durante la conferencia virtual de julio,
Jakob Nielsen held a Q&A session.
Jacob Nielsen tuvo una sesión de preguntas y respuestas.
In that session, Drew from Singapore asked
En esa sesión, Drew de Singapur preguntó,
what are the potential UX problems
¿Cuáles son los posibles problemas de UX
for virtual reality design
para un diseño de realidad virtual
and how can we evaluate VR applications?
y cómo podemos evaluar las aplicaciones de la VR?
- Yeah well virtual reality is an,
Bien, la realidad virtual es, claro,
of course it's a new media form, right?
una nueva forma de media, ¿cierto?
It's a new computer format and so that gives
Es un nuevo formato de computadora que lleva
its problems in its own right in that users don't know
a sus propios problemas ya que los usuarios
how to use even the most basic operations.
no saben usar las operaciones más básicas.
And I think in, so that's a concern right there,
Y creo que eso es algo que tener en cuenta,
in addition to the standard concerns
junto con otras preocupaciones,
about what features should we have,
sobre las características que deberíamos tener,
how do we support the application,
como dar soporte a la aplicación,
but we even need to support
y sobre todo dar soporte
people just being able to manipulate the user interface.
a la gente para que sean capaces de manipular la interface.
And so this is very similar actually to how it was
Y esto es muy similar a como era todo
back in the 1980s when you know,
en 1980, ya saben,
I did do early usability studies
hice algunos estudios de uso
and we had the first kind of commercially available
y teníamos disponibles a la venta las primeras interfaces
graphical user interfaces with things like a mouse
gráficas de usuario con cosas como el mouse
and all of that and so at the time, you know,
y todo eso, y en ese tiempo
Apple actually shipped the Macintosh with a little animation
Apple enviaba la Macintosh con una pequeña animación
kind of introduction to how to use a mouse.
introductoria de como usar el mouse.
But as you know, in any kind of computer training,
Y como saben, con cualquier entrenamiento de computación,
some people get it out of the box, they get the training
algunas personas las sacan de la caja y hacen el entrenamiento
and other people just get the computer without the training
y otras personas no hacen el entrenamiento,
and so, people would just walk up to a computer
y así, algunos sacan la computadora,
and see the mouse for the first time,
ven el mouse por primera vez
had no idea what to do and actually, you know,
y no tienen idea de que hacer y, de hecho,
so some of these studies were like,
en algunos de estos casos
people will use it like,
la gente los usaba así
oh, this is where I could remote control,
como si fuera un control remoto,
click (mouse clicking)
haciendo clic
make something happen.
y esperaban que algo pasara.
Or other people would like turn it around.
O algunas personas lo voleaban.
This was like, back this mouse, which had like a roller ball
Eso era cuando los mouse tenían un bola
so they'd use it, like a track ball.
y las usaban como ruedas de desplazamiento.
And you also have these like, (grunts)
Y también hacían esto
very tentative mouse movements.
esta clase de movimientos titubeantes.
So that is what we saw back in the days
Eso es lo que veíamos antes
and you had to teach people how to use a mouse
y tenías que enseñarle a la gente como usar un mouse
before you could even get into starting the other things.
antes de poder empezar con otras cosas.
And in VR, you're going to have similar problems
Y con la VR vamos a tener problemas semejantes,
and you actually, many ways going to have worst problems
y en algunos casos vamos a tener problemas mayores
because manipulating a virtual reality
porque manipular la realidad virtual
has many more degrees of freedom or degrees of complexity,
da mucha más libertad y complejidad
than using a graphical user interface
que usar una interfaz gráfica del usuario
because typically, you know,
por, típicamente,
things like scrolling, for example, right?
algo como el desplazamiento, por ejemplo.
You have two dimensions of scrolling
Tienes dos dimensiones para desplazarte
and actually for websites, we even like say yes,
y para las páginas web podemos ver
scrolling up, down.
desplazamiento de arriba hacia abajo.
Yes. Scrolling up, down.
Si. De arriba a abajo
Scrolling left and right.
o desplazamiento de izquierda a derecha.
That's not so good for websites typically,
Eso no es tan bueno para las páginas web,
so websites is even simpler.
así que las páginas web son más simples.
But traditional applications, they do
Pero en la aplicación tradicional
two dimensions of scrolling, right?
tienes dos dimensiones de desplazamiento, ¿verdad?
But in VR you have, first of all you have,
Pero con la VR tenemos, primero que nada,
your position in that, the world.
tu posición en ese mundo.
That's three dimension of where you are
Ahí tenemos tres dimensiones
and then you have your direction of viewing,
y también tenemos la dirección en la que miras
which also has three dimensions of freedom.
que son otras tres dimensiones de libertad.
And so there's six dimensions, total you've got to control
Así que tenemos seis dimensiones que controlar
and so that's a vast, additional complication.
y esa es una vasta complicación adicional.
And then in addition to that,
Y también hay que agregar
you have that there's no real conventions or standards for
que no hay estándares convencionales
how things are represented and what you're going to do
sobre como se representan las cosas o lo que vamos a hacer,
and then, you know, we have our standard usability problems,
y también tenemos los problemas de uso normales,
which is the application, the tasks,
que son las aplicaciones, las tareas,
actually doing something useful
hacer algo realmente útil
and this is where I would really recommend
y es aquí donde recomiendo
significant user testing.
mayores pruebas de uso.
I mean, I always recommend for anything, as, you know,
Y si tengo que recomendar algo aquí,
I always recommend just doing usability studies,
es que hagan estudios de uso,
but I think much more so when you're in a new technology
especialmente si usan tecnología nueva
where you have these problems with just basically operating it,
donde puede haber problemas usándola,
which can trip up completely any otherwise good design.
lo cual puede hacer tropezar un diseño muy bueno.
But then furthermore, there's that question of
Más allá de eso, está la pregunta,
is that application even useful at all?
¿es esta aplicación realmente útil?
And I really advise, don't just like demo it
Y ahí sugiero, no sólo demostrarla
or just don't show to people say, "do you like it?"
o sólo enseñarlo a la gente y preguntarles si les gustó.
Because yes these are
Por que sí,
kind of cool right now for many people,
esta tecnología es genial para mucha gente,
but do they really add anything
pero, ¿aportan algo realmente,
do they really do anything useful
hacen algo realmente útil?
and useful can be in many ways, I mean,
Y utilidad significa muchas cosas,
useful could act to just be that it's fun and enjoyable,
utilidad puede ser simplemente algo divertido y entretenido,
particularly if it's a game, but there could also
en particular si es un juego, pero también puede tener
be also more kind of enjoyment style applications like
otras aplicaciones de entretenimiento como
touring a tourist site to think
visitar un lugar turístico y ver
if you want to go there on a vacation
si queremos ir de vacaciones
or touring a house that's for sale
o ver una casa que está en venta
before you go out there, you know,
antes de ir allá, ya saben,
make your way physically there to see the house.
hacer que estemos físicamente ahí para ver la casa.
There are a lot of those types of applications,
Yo tendría muchos de esos recorridos educacionales
campus tours for universities and so forth.
en facultades de universidades y esas cosas.
But do they really add anything over,
Pero, ¿ofrecen algo realmente,
just a set of a slide show?
esta presentación de diapositivas?
And then you have real applications
Y luego tenemos aplicaciones reales
where you're actually doing something
donde estas haciendo algo concreto
and they're even more so,
y lo que es más
we've got to do this sort of standard usability testing
tenemos estos estándares para pruebas de uso
of giving people tasks.
que son darle tareas a la gente.
Actually do something real, discover something,
Hacer algo, realmente, descubrir algo,
find something, do something, accomplish something
encontrar algo, hacer algo, lograr algo
and then see if people can do it.
y luego ver si la gente puede hacerlo.
And then there's some tweaks in how you run those studies,
También puedes perfeccionar cómo ejecutar estos estudios,
compared to a normal study,
comparado con un estudio normal
for example, that was actually just some research done.
y hay una investigación al respecto.
That's shown if you're gonna do a survey to users like
Eso se muestra en como hacer una encuesta a usuarios
how much do you like this design for example,
como, ¿te gusta este diseño?, por ejemplo,
on a one to seven scale or something.
en una escala de uno al siete, o algo.
It's better to do that as a simulated survey
Es mejor hacer eso con una encuesta simulada
within the virtual reality
en la realidad virtual
than to have people like take off their goggles
que hacer que la gente tenga que quitarse los lentes
and then have a sheet of paper and they mark, you know,
y luego en una hoja de papel que pretendan
six, five, three, whatever.
escribir el número seis, cinco, tres o lo que sea,
Because that takes them out of the world
porque eso los saca del mundo
and that's sort of distracting to be in, out, in, out.
y puede distraer mucho estar dentro y fuera y dentro.
So even though it's also a little bit here's like
Y aunque sea algo pequeño como,
you pop up in the world, here's like like a survey,
entrar en el mundo, aquí está la encuesta,
while you're like fighting dragons or something but
mientras peleas con dragones o algo,
that's actually better to do.
es mucho mejor hacer eso.
So there are some tweaks in how you may run to study,
Esas son algunas mejoras a como aplicar este estudio,
but honestly, the way to run usability studies
y la manera de llevar a cabo estudios de uso
with virtual reality, it's like
en la realidad virtual,
run any other usability study,
es como cualquier otro estudio de uso
which is particularly, I mean,
en el sentido de que
first of all, you'll get representative users and so on
primeramente consigues representantes de usuarios
and then as I said, give them tasks.
y luego les das una tarea.
Don't just like play around with this.
No es solo jugar con eso.
That can also be a task. See what you like,
Aunque esa también puede ser una tarea y ver si les gusta.
but also actually do something real
Lo importante es hacer algo real
and see if people can do it
y ver si la gente puede hacerlo
cause that's when you'll discover
porque ahí es cuando descubren
that your controls don't work or your
si tus controles no funcionan
conceptual model for the application
o si el modelo conceptual de la aplicación
completely doesn't match what people want to do.
coincide con lo que la gente quiere hacer.
