This chapter discusses Complex Morlet Wavelets, how they extend on Morlet Wavelets from last chapter to extract phase and power information, and mechanisms of imaginary numbers to accomplish this. Also covers some practical advise on using them. 13.1 The Wave...

HERE BE THE DEMONS - Right now VR on Linux is rough, particularly depending on the hardware you have. If you are completely new to Linux in general, you should be wary about diving straight into it for VR use cases. You may wish to look into dualbooting to hav...

Here is a non-exhaustive list of communities that might be worth looking into for various VR topics. Please note this is focused on communities centered around developing something, or larger VR tech enthusiast communities (IE not small friend group discord se...

Welcome to Virtual Reality! There are a lot of available VR headsets to pick from to jump into / upgrade your VR experience. This is a non-exhaustive list explaining what headsets would be good for what usecase. Before choosing a headset, its important to c...

What is full body tracking? Full body tracking (also known as FBT) refers to allowing tracking of more than the hands and head in VR, typically referring to the legs and hips of a user. This is typically done using trackers that are worn by the user. What is...

What is Face Tracking? What Face Tracking hardware should I get? TODO    

There are various methods headsets, controllers, and body trackers use to know their location in their environment. This page discusses the classes devices tend to fall under, and the various pros and cons you would expect a device of a class to likely inherit...

The poor-mans risky watchman dongle! WARNING: Messing with firmwares can potentially result in bricks, be wary and double check your dongle is supported as per the requirements! Furthermore, please understand that this is not supported by SteamVR officially! ...

This quick book discusses the Fourier Transform, general knowledge needed to understand it, and some examples of applications. I wrote this in the context of neural signal processing. So while this book is still going to be applicable to other usecases as well...

The main thing to understand is that the Dot Product is a process that takes 2 vectors of equal number of elements, and returns a single scalar number representing the correlation between the 2 input vectors. The dot product comes up in many areas of math, su...

The main thing to understand here is the equation of the sine wave, and how each variable affects the wave (how it looks). Sine waves are a cyclic function that oscillates.  Their general formula is the following: Where: A is the amplitude (the heigh...

The main thing to understand is that Complex Numbers are a way to express numbers on a 2D plane, which is a useful abstraction for concepts such as those in Fourier Transforms You cannot generally take the square root of -1, so a shorthand way of writing the ...

Eulers formula is the following:   however, it can be rewritten (and in which form is more important to us) as for following: This can be plotted on the complex plane as per the following: We can see theta represents the angle from the x "real" axis ...
