I'm Seth Schneider, and this is VRUX.

In this episode, we discuss VR sickness, and some best

practices to avoid it.

VR sickness is the uncomfortable feeling

that can happen when your eyes and your inner ear

are telling your brain different things about how you're moving.

Like motion sickness, it is quite common,

and can cause nausea, and even vomiting.

Modern VR systems have greatly improved user experience,

but sickness is still a serious concern.

Responsible developers should consider these tips

when creating VR applications to ensure

the highest level of immersion and comfort for their users.

Responded accurately to users movements

at all times, preferably near typical human locomotion

speeds.

Strive for zero latency, especially in head tracking.

Take Intel innovator Pedro Kayatt's game,

Apocalypse Rider.

It's a Mad Max inspired motorcycle

game that uses natural body movements for control.

This results in little to no VR sickness.

As you tilt your head, the motorcycle moves left to right.

Using the natural movement of the player

and matching the in-game visuals is an effective way

to reduce motion sickness.

You should also maintain frame rates equal to or greater

than the hardware refresh rate to avoid judder.

90 FPS is considered the minimum comfortable frame rate.

There are other tricks, like re-projection,

that can be used to keep the experience

smooth and comfortable, but should be avoided if possible.

Give users the opportunity to calibrate stereo offset

or enter pupillary distance.

Avoid moving objects that take up

a large portion of the user's field of view

to prevent feelings of self-motion.

Locomotion is a challenge.

Make acceleration infrequent and short,

preferably instantaneous.

In teleporting, provide adequate visual cues to retain bearings

and preserve original orientation.

These aren't hard and fast rules,

but by following these suggestions,

you can cut down on VR sickness, increase immersion,

and make your VR experience more comfortable.

Thanks for watching.

How Computers Work: Hardware and Software - Duration: 5:23.

[whoosh]

[ding]

[music]

Hi, my name is Erica Gomez and I'm an engineering manager at Amazon.com.

One of the best things about working in tech, and at Amazon in particular,

is that I get to bring my dog with me to work every day.

My job is to help make sure software gets out the door

and her job is to nap under my desk and snore very loudly.

[music]

My name is Jerome Holman, and I'm a Program Manager on Team Xbox and I have a really fun job:

Basically bringing the hardware and the software together

to give you all the games that you love on your Xbox.

Whoa!

Ha!

[music]

When you look inside a computing device you see a bunch of circuits, chips, wires,

speakers, plugs, and all sorts of other stuff.

This is the hardware.

But what you don't see is the software.

Software is all of the computer programs, or code, running on this machine.

Software can be anything from apps and games

to webpages and the data science software that me and my teams use

at Amazon to understand how customers behave.

But how do the hardware and the software interact with one another?

Let's start at looking at a computer's central processing unit, or CPU.

The CPU is the master chip that controls all the other parts of the computer.

[music]

A CPU needs to do different things so inside it has smaller, simpler parts that handle specific tasks.

It has circuits to do simple math and logic.

It has other circuits to send and receive information to and from different parts of the computer.

[music]

The real magic of the CPU is how it knows which circuits to use and when to use them.

[music]

The CPU receives simple commands that tell it which circuit to use to do a specific job.

For example, an "add" command tells the CPU to use its outer circuit to calculate a new number.

[beeping sound]

And then the "store" command tells the CPU to use a different circuit to save that result into memory.

[music]

Just like numbers, all of these simple commands can be represented in binary ones and zeros

or on and off electrical signals.

[music]

The binary commands are stored in memory and the CPU fetches and executes them in sequence one after the other.

[music]

This sequence of commands is, in fact, a very simple computer program.

[music]

Binary code is the most basic form of software and it controls all the hardware of a computer.

These days, nobody writes software in binary. It would take forever!

Today, the software we write looks more like

this,

[pause]

or this,

or even this.

Programming languages like these let you type in commands in something that looks a lot like English.

[music]

To draw a rectangle on the screen, you just need a single command.

This high-level command is converted into hundreds, or thousands, of simpler binary commands that the CPU understands.

[piano music]

Software tells the CPU what to do,

but when you're listening to music, and browsing the web, and chatting with a friend,

your computer is running multiple pieces of software all at once.

So, how do all of these programs get on the computer in the first place,

and how can the CPU run them all at once?

To find out we'll have to take a look at the operating system.

[music]

The operating system of the computer is the master program

that manages how software gets to use the hardware of the computer.

For example, I helped create the Windows operating system that runs on most personal computers.

[music]

The operating system is a program with special abilities that let it control the other software on the computer.

It lets you install new programs by loading them into your computer's memory.

It decides when a program is run by the central processing unit,

and whether that program can access the computer's input and output devices.

And when you think your computer is running many programs at once,

in reality, it's the operating system that's quickly switching

between programs sharing that CPU for fractions of a second.

[music]

Inside every computer is an operating system managing software that controls the computer's hardware.

The software is a series of commands made of simple binary code,

and that binary code is just electrical signals flowing through billions of tiny circuits.

[music]

Computers have the potential to do all kinds of amazing things.

But the only thing that makes the computer smart, or useful, is you.

When you learn to code you get to define the problem you want to solve, and write the software that turns those ideas into reality.

That gives you the power to build things that matter to you, your community, and the world.
