TEST: introduction VR-methods (lesson 5)
Setup for Testing my experience
Main objective for research: what do I want to find out?
Main research question
SubquestionsTaxonomy of usability characteristics
Methods for testing in Virtual Environments
# Exercise 1: VR versus GUI
Define virtual reality and briefly review the major types of VR technology:
VR-desktops
Head mounted displays (HMDs)
Cave Automatic Virtual Environments (CAVEs)
2. Categorise some of the major differences between VR and traditional user interfaces such as GUIs – and how these differences lead to specific types of usability evaluation issues.
# Exercise 2: expert evaluation methods (without users)
