Welcome to Day 35 of

To Be A Product Manager

As I said, this is the most intense week since I joined this startup. There』re meetings going on all day with a bunch of unexpected tasks coming up. I original plan is to design another VR lobby wireframe and interaction details, but things just not turned out the way you want it.

I help set up some VR devices on investor meeting early in the morning, then I got in meeting discussing terminology we are using in Millbrae and Shenzhen.

Then I did some translation work between our American colleagues and local engineers and successfully set up the server.

Today I will mainly answer the question I posted in yesterday journal. You will see it below.

Goals

Server set up
VR lobby wireframe
Read Development document

Challenges

So I noticed the difference of FOV(field of view) in each eye:

Why my left eye has a broader view to the right and my right eye has a broader view to the left?

This is exactly opposite from our common sense. I read a lot of stuff online and then also ask some senior engineer in our company, then I just figured out an explanation couple hours ago, and wrote a document on my co working platform.

This might be useful for someone who is also curious about this and google for answers.

First, you might misunderstand 「field of view」 under different circumstances.

It is known to all that our left eye can see more space to the left, and right eye can see more space to the right.

But when we look at a certain object, both of your eyes will gaze at one point. What you call 「field of view」 is not a general FOV, but a small range of angle.

Things outside that area will become blurry, because you want to focus on thing you want to pay attention to.

If the object you are looking at is in the middle, at this moment, your left eye is looking to the right while your right eye is looking to your left. And there』s an overlap on the object you see, and you are looking like this:

For example, just put your finger in front of your nose, and starting looking at it. If you close an eye, say your left eye, the finger you see from your right eye is definitely on your left, with the left background behind.

Can you see the rest of the space on your right?
Of course yes, it is just blurry.

Second, it is about our brain and image process system.

What we capture from two eyes are different, but then our brain is going to combine the two pictures into a single three-dimensional image. This three-dimensional image gives us depth perception.

You might ask:

Why I can still tell the depth even if we are perceiving the same content from both eyes?

In fact, it is still because our brain tell us the distance from its experience. We are deceived by perspective optical illusion, just like what this photo does to our brain:

My name is Zake Zhang, a newbie VR product manager based in Shenzhen, China. I』m thinking what if I write daily product journal for 1,000 days?

Thanks for reading and let』s keep on hacking!

Warm Regards,

Zake

be so good they can』t ignore you.
