Curso 1 de 5 en SpecializationVirtual Reality

This course will introduce you to Virtual Reality (VR). The course will teach you everything from the basics of VR- the hardware and the history of VR- to different applications of VR, the psychology of Virtual Reality, and the challenges of the medium. The course is designed for people who are new to VR as a medium. You may have experienced some virtual reality before, and may have some hardware- but this course is suitable to individuals who have never experienced VR and those who do not have much hardware- we will explain Mobile VR as well as devices such as the Oculus Rift and HTC Vive. Introduction to Virtual Reality is the first course in the Virtual Reality Specialisation. A learner with no previous experience in Virtual Reality and/or game programming will be able to evaluate existing VR applications, and design, test, and implement their own VR experiences/games using Unity by the end of the specialisation.

Virtual reality can be used in medical training in many different ways.

In this video, we look at some of the applications in this area.

First, VR can be used in immersive learning.

Medical students can experience a surgical room through a 360 degree video,

which captures real operations, and can be viewed on mobile VR devices.

In this case, by being virtually inside the operation room,

students are not only familiarizing themselves with the medical procedure.

But also with the emotional stress triggered by

an emergency situation that may arise during the operation.

VR could also be used in surgical skill training.

The idea here is that before performing surgical procedures on real patients,

students can try to do it virtually.

This is technically a bit more complicated.

You would need model based VR, which would need to be programmed

to respond to users' operations with real-time animation.

Another issue is that, in order for students to really learn how to

operate with their hands, we would need very high-end VR interaction devices.

Which not only track the position and rotation with high precision, but

could also provide realistic force feedback.

This certainly goes beyond the capacity of any device

you can find in a consumer market.

Finally, VR can help medical doctors to improve their social skills, especially

when it comes to dealing with patients who are very demanding, very emotional.

Or, who have mental health issues that need to be dealt with sensitively.

We developed an application for

this in 2015 where we recruited several doctors, and

trainee doctors, to go through a virtual consultation with virtual patients.

The scenario had to be very interactive, in a realistic way, so

it was implemented with model based VR.

We animated and programmed some virtual patients

to interact with the doctors verbally and non verbally.

But this was not entirely autonomous.

We had a trained experimenter sitting in the same room to monitor the situation,

and they would select what the virtual patients did next.

We found that qualified doctors were more likely to be able to resist unreasonable

demands from the virtual patients than less experienced trainee doctors were.

We will explain the technical detail of this later in the specialization,

but let's watch the following video first.
