The history of WebEx are he could argue that the history of the NSA are the two technologies, the foundation

of WebEx are began even before motion pictures.

Victorian's marveled at stereoscopic pictures and in a sense, the use of lenses and provide in a slightly

different view.

Fritschi is one of the cornerstones of the VR headset.

But I feel that the story really begins in 1960 with the head site.

The first HMD head mounted display the device used had movements to control a remote camera and had

a video screen for each eye.

At the time, the idea of virtual reality hadn't even been considered.

The device was used to be able to remotely view a dangerous location.

The father figure of VR and much of computer graphics is Ivan Sutherland, who back in 1965 described

a device he called the ultimate display.

This device would, via an HMD present, a virtual world with which the viewer could interact.

The paper he presented can be described as the blueprint for future VR development.

Three years later, with his student Bob's role, he created the first VR air head mounted display.

Connected this time to a computer, not a camera, he was so heavy it needed to be connected to the

ceiling and was given the name the Sword of Damocles.

It was nearly 20 years later, in 1987, the term virtual reality was first used.

During that period, flight simulators and hand tracking gloves were developed.

Arcade machines arrived in the early 90s, pioneered by the Virtuality Group.

In an attempt to reach a wide audience, Sager experimented with VR headsets for the technology of the

early to mid 90s, made creating the devices for an acceptable price point.

An adequate performance was just not feasible.

We need to jump forward to 2008 for the first application of VR, a German advertising agency created

a market based app.

Market based means the camera review is process to scan each frame of video for a marker image.

If the image is found, then its position and orientation in screen is calculated in order to position

a virtual object in its place.

Customers who bought a magazine and used the app were able to see a BMW mini appearing out of the magazine

advertisement in 2011, National Geographic got in on the Act and Coca-Cola in 2013.

In 2012, we see the launch of Oculus Rift headsets and Google created the cardboard device allowing

mobile phone users to play with VR at a very cheap price point.

As mobile devices get more and more capable with faster processors and great graphic capabilities,

they also have some amazing sensors that can be used to determine their position and orientation.

You probably own a device is capable of showing and they are content.

Virtual reality for the web has been around for over 20 years.

They are Emelle virtual reality markup.

Language was first specified in November 1994.

They are Emelle never really took the world by storm.

But the latest devices, mobile phones and VR headsets are really starting to make immersive experiences

on the web, a reality, albeit a virtual one.

The story of WebEx are started with Apple creating a market and Google Arcore.

Both these cold libraries harness the sensors on mobile devices and attempt to convert the data into

a 3-D analysis of the real world.

Using this data is possible to determine a view is position and orientation, which in WebEx ASPEY we

call a pose.

But the technology goes further than just understanding the viewer's pose and then positioning virtual

assets in a 3-D rendered view that are tracked by the viewer as they move their mobile devices or move

their head if using a headset in the example of a headset.

The view in the left and right eyepieces are subtly different, taking account of the distance between

the eyes.

The result a very convincing, immersive experience.

Once they are in our core, provided the essential low level code necessary to use the sensors in this

way.

It was only a matter of time before this was available in the browser.

Surprisingly, after being first on the table with the Arquit, Apple had been a little slow bringing

the technology to the default browser Safari.

Whereas Google brought this level of tracking to the Chrome mobile browser with version 81 at the time

of record in the Can I use website, a great resource for developers shows the edge in Chrome, agreeing

for WebEx are in the desktop and just Chrome on the mobile browser.

So you're at the cutting edge of web technologies here.

To get to grips with this technology, you're going to need to know how 3D works and we'll look at that

briefly in the next video, see in a minute.
