If you ever tried a VR headset at home, you probably know that full immersion can be dangerous for your surroundings. When I was setting up the IGD301 VR project in Unity, I punched my laptop screen very hard with one of the controllers (it survived no worries!).
These moments are VR fails, when the immersion make you forget about reality. Here I will present 2 scenarios where immersion can be dangerous.

Today’s blog post is all about evaluation. We will see how we can evaluate a selection technique, and how we can use the results to find ways to improve it.

Okay the course is coming to a close and now we have to make a final project. The task is quite straightforward: select grocery items in a supermarket.
The idea is to implement one of the selection techniques of last time and evaluate it along a few metric such as accuracy, speed, user satisfaction, etc. This blog post will cover the implementation of the technique and the next one will cover the evaluation.

Raycasting from the eyes In mainstream VR, the most common selection technique is raycasting from the controller. It is simple and cheap to implement, but having to move the hands around can be tiring.

Using your gaze allows for a very natural way to select distant object (the reach is infinite). It is used in newer headsets such as the Apple Vision Pro that take advantage of cutting edge hardware.

When talking about VR nowadays, we often think about headsets and controllers. But VR is far more diverse than you would think at first glance. In this post, I will present the CAVE system, an alternative to headsets that is still used today in many research labs.
What is a CAVE? CAVE stands for Cave Automatic Virtual Environment. It is a room where the walls are screens and where you can walk around freely.

Let’s do some real VR development! The school lent me an Oculus Quest, so I will be doing the next tutorials with it.
What are we doing today? Okay so last week we created a simple game, following the Roll a ball tutorial from Unity. The ball was controlled using the keyboard, but today we will control it by grabbing the game board with our hands, and moving it around to make the ball roll!

This blog post is the 2nd in the VR with Unity series.
This week, we are setting a small scene in Unity to get familiar with the editor and have something to work with in VR next week. This is essentially the Roll a Ball tutorial from Unity, but with a few changes.
If you already know how to use Unity, you can go crazy and expend on Roll a Ball as long as the core mechanic is the same (we will need it next week).

Hello, welcome to my blog! This is the first post of a series of posts about VR development with Unity. I am currently a student at Telecom Paris and writing this blog is part of our assignment. I will try to keep things as simple as possible so that everyone can follow along.
For this first part, I will only cover the setup part of our development environment with Unity. If you already have Unity installed and know how to use it, you can skip this part.
