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
6Conjoint 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?

Experimental Design
10Intention
- 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.

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