Research Context
4
  • Research project is part of the VR-DIS platform.
  • Given the acronym ICARUS
  • A System for Interactive Conjoint-Based Analysis
    in Virtual Reality of User
  • Satisfaction and (Complex) Decision Making

Introduction
6
Conjoint Analysis is used to describe a technique
for estimating the value people place on the
attributes or features which define products,
services and design alternatives.
  • In a conjoint study, a researcher
  • selects attributes (characteristics, features)
  • classifies attributes into levels
  • combines attribute levels into profiles

Is it possible to develop a VR based system of
conjoint analysis?

Intention
  • A sever hosts the experiment and supports a
    series of page accesses by the same client.
  • General information about the subjects is
    logged.
  • Session state information is collected during
    the course of the experiment.

  • Data is being collected.
  • This methodology offers the potential of an a
    priori evaluation of design performance and an
    opportunity for generalizing the findings.
