A Tool for Learning Digital Filters in Virtual Reality

Abstract: There are various tools used for teaching purposes, be it computers or even pen and paper. Virtual reality is used to simulate immersive environments. While it is mostly used in the video game industry we have made an attempt to use it as a learning tool, in this case for courses related to signal processing by trying to build intuition for digital filter design. The end product is a tool in virtual reality that allows the user to alter digital filter specifications and see how these alterations affect it. With this project we show that there is potential for virtual reality to be used as a teaching assistant. The main drawbacks for tool creation in virtual reality are that there is a limited amount of frameworks that support virtual reality and that they are mainly created for video game development.
