Our brains do a magnificent work to

Optical illusions can trick our minds into
believing what we're seeing is real.

Introduction

Virtual reality (VR) is
The application of computing technology
Create images of 3D scenes
Users can navigate and interact with an environment via
input/output devices(Lin et al. 2015).
Introduction

Successful VR
 Creating acceptable substitutes and sometimes outperform
physical environments
 They take no space and can be accurate and realistic
 They can be animated, illuminated, copied, and shared;
 Users can navigate and interact with them
(Lin et al. 2015).

VR Applications
 Medical treatment of Autism
Spectrum Disorder (Cox et al.
2017)
 Social stress (Hesse et al. 2017)
 Training, education-geography
learning (Lv et al. 2017)
 Entertainment, sports, and gaming,
concurrent engineering (Vince

knowledge to the real-world distance estimation

Performance Evaluation
HMD
The whole world “rotates”
More sensitive to head
rotation errors
Significant reduction in
task
Causes distortion, which
requires computational
correction.
Projection
The whole world “ move by
only a few inches.”
Do not have distortion
problems.
Do not operate well in bright
environments.

Presence and Comfort
Presence is defined as the subjective
experience of being in one place.
Experiencing discomfort as a side effect of
using VR systems has been the largest
threat to widespread adoption of the
technology over the past decades.

Introduction

The best case is that you replace these words with
pictures. But to brainstorm, bullet points aren’t a bad
place to start. Also you can experiment with using
presentation notes (but those keep you at the podium.)
What are we going to
learn? (and why it’s
important to learn now).

The specific takeaways
you’ll get.

No need to fill out this slide, just a place
keeper to introduce the second of “before
and after” narratives and case studies.
The before and after.

Ideally narratives that expose your
shortcomings, encounter objections, or
illuminate key elements of the solution.
Before situation #1.

Be sure to outline how your audience can
avoid these mistakes.
The mistakes people
make.

What you can do to take
action now.
