VR Experience Design | Lakshmi Pratap

Project Overview

How do you design a VR experience immersive enough that users temporarily forget their physical surroundings? This project builds a fear-based experience to find out — through UX research, iterative design, and user testing.

My Role

UX Researcher, Experience Designer, VR Developer

Duration

4 months (Solo Project)

Tools & Methods

User interviews, Thematic analysis, Unity, Meta Quest Pro

Participants

13 total (8 interviews + 5 testing)

The Design Challenge

Create a VR experience that induces such strong emotional immersion that users temporarily disconnect from physical reality — a state where the mind fully engages with the virtual while the body is momentarily "forgotten."

The Goal

Design an experience that creates measurable mind-body disconnection through controlled emotional intensity

The Question

What environmental, interaction, and sensory elements are necessary to achieve this level of presence?

The Approach

Use fear of heights as the emotional trigger, validated through user research and cultural understanding

Why This Matters

Designing for heightened emotional states in VR has practical applications across multiple domains:

Therapeutic VR (exposure therapy, PTSD treatment)

Professional training simulations

Entertainment & immersive storytelling

Educational experiences

Research Foundation

Before designing, I needed to understand what creates immersion and what makes people feel disconnected from reality — so I approached it from multiple angles.

Understanding Mind-Body Disconnection

The target state: moments when emotional or sensory intensity causes the mind to become so absorbed that physical awareness fades. This happens naturally during:

Extreme fear or stress situations

Sleep paralysis experiences

Intense emotional moments

Deep meditation or flow states

Cultural Validation: Audiences Already Understand This

Before primary research, I looked at how popular media portrays mind-body separation. Billions of dollars in box office revenue suggests audiences worldwide already grasp this concept intuitively.

The Matrix (1999)

Humans live entire lives in a simulated reality while their bodies stay dormant — the mind exists independently from the body

Design Insight: Complete virtual immersion can feel "more real than real"

Avatar (2009)

Identity survives a transfer into an entirely different physical body — proof that self is tied to consciousness, not form

Design Insight: Identity is tied to consciousness, not physical body

Divergent (2014)

Fear simulations immersive enough that characters forget their physical reality mid-experience

Design Insight: Fear is a powerful trigger for full immersion

These films' combined $4+ billion box office validates that the concept resonates globally — meaning I could design for an experience users would conceptually grasp, even without having personally lived it.

Primary User Research

Ran semi-structured interviews with 8 participants to understand what creates immersive VR experiences and what triggers strong emotional responses.

Research Goals

Understand what makes VR experiences feel "real"

Identify environmental factors that enhance immersion

Surface past experiences of feeling disconnected from reality

Learn preferences for interaction and control in VR

Method

Format: Semi-structured interviews

Duration: 20 minutes each

Questions: 10 open-ended

Analysis: Thematic analysis to identify patterns

Key Findings: 6 Design-Critical Themes

01

Visual Realism Drives Believability

High-quality graphics were consistently essential — users disengage the moment visuals feel artificial.

"If the sound doesn't match the visual, I start imagining how the visual should look"

Design Implication: Must use photorealistic textures and real-world imagery

02

Emotion Amplifies Immersion

Strong emotions — fear, awe, excitement — make users forget their surroundings; intensity tracks directly with presence.

"I would wake up feeling like I was being choked... I couldn't move. It was very scary."

Design Implication: Use fear of heights as primary emotional trigger

03

External Control Enhances Presence (Counterintuitive)

Moving users without their input increased immersion by closing the cognitive gap between virtual and real.

"The entity will correct me to urge my hand in the right direction... that made it more realistic"

Design Implication: Remove user control during peak emotional moments

04

Height Triggers Visceral Response

Vertical space consistently triggered physical sensations, even in users who knew they were safe.

"Motion plays a big role in immersion"

Design Implication: Design for extreme vertical elevation

05

Audio-Visual Synchronization is Critical

Spatial audio matched precisely to visuals was essential — any mismatch broke immersion instantly.

"Gaming, especially with social interaction, can make the experience feel very real"

Design Implication: Synchronize spatial audio with all visual elements

06

Real-World Environments Work Best

Users trusted realistic recreations of real places over fantastical environments.

"You could recreate real places and give users the feeling of being there. That would be immersive."

Design Implication: Use real city panorama for height reveal

All external distractions eliminated

Experience Design Solution

An elevator experience that leverages three research-validated triggers — fear of heights, spatial contrast, and autonomous control — building emotional intensity across four choreographed phases.

Design Concept Rationale

An elevator scenario is the perfect framework: it's familiar (low cognitive load), naturally involves vertical movement (the height trigger), and allows for dramatic spatial reveals. The confined-to-open transition maximizes emotional impact through contrast.

Experience Flow & Design Decisions

Phase 01: Establish Baseline

User sits in a dimly lit elevator. The familiar, enclosed space establishes a "real" baseline before any virtual elements appear.

Design Rationale: A real chair matched to the virtual seat keeps physical and virtual aligned, and the familiar setting lowers cognitive load before anything virtual begins.

Phase 02: Build Anticipation

Slow upward movement with mechanical sounds. Moving brick walls give elevation cues through motion parallax without revealing the destination.

Design Rationale: Visual-vestibular conflict heightens the sense of height, while the gradual pace and mechanical audio build tension and ground it in realism.

Phase 03: Dramatic Reveal

Doors open onto a 360-degree cityscape from extreme height. The sudden shift from confined (safe) to infinite (exposed) is the peak emotional moment.

Design Rationale: Real city panoramas give authentic depth and scale, and the suddenness of a full 360-degree reveal amplifies impact through contrast.

Phase 04: Loss of Control

The camera autonomously moves into open air without user input, creating an out-of-body sensation as the system takes over at peak fear.

Design Rationale: Removing agency at the emotional peak paradoxically increases immersion (Finding #3), while smooth, pre-programmed movement avoids motion sickness.

Technical Implementation

Built from scratch in Unity and C#. As a designer new to VR development, I taught myself the technical skills needed to prototype and iterate quickly.

Unity 2022.3

Chosen for robust VR support and fast prototyping — enabling the quick iteration cycles that user testing demanded.

Meta Quest Pro

Selected for its 2160×2160 per-eye resolution, critical for visual realism, and wireless freedom for natural movement.

Key Technical Design Decisions

Camera Animation System

Smooth autonomous camera paths, built with Unity's animation curves and tuned to prevent motion sickness without losing emotional impact.

Lighting Design

Lighting shifts from warm, enclosed elevator light to cold, harsh exterior — reinforcing the move from safe to vulnerable.

Spatial Audio Integration

Mechanical, ambient, and silent moments layered and synced precisely with the visuals to avoid any immersion-breaking mismatch.

User Testing & Iteration

Ran pilot testing, then a refined final round. Each round surfaced insights that reshaped the experience.

Pilot Testing: Learning What Doesn't Work

Problems Identified

Issue: Initial tunnel view failed to convey height Impact: Users didn't feel afraid, breaking the core experience goal

Issue: Low-quality textures looked artificial Impact: Broke immersion immediately (Finding #1)

Issue: Static camera reduced engagement Impact: Users stayed observers, not participants

Design Iterations Made

Solution: Replaced tunnel with 360° cityscape panorama Result: Dramatic improvement in reported fear response

Solution: Upgraded to high-resolution photorealistic textures Result: Users stopped mentioning visual quality

Solution: Added autonomous camera movement system Result: Users reported out-of-body sensations

Solution: Enhanced lighting contrast for dramatic effect Result: Amplified emotional impact of the reveal

Final Testing Results

Tested the refined experience with 5 participants. Results validated the design decisions and research hypotheses.

100%

Reported Physical Sensations

All 5 users felt bodily responses (stomach drops, vertigo, muscle tension) despite consciously knowing they were in VR

80%

Achieved Target State

4 out of 5 users reported temporary disconnection from physical surroundings during peak fear

2-3

Experience Duration (min)

Limited by safety protocols; users indicated 5-7 minutes would deepen the effect

Validated Design Decisions Through User Feedback

Emotional Trigger Validated

The fear response worked exactly as designed, confirming that emotion drives immersion

"When I looked straight down, my fear increased exponentially. It's like when your tummy kind of drops"

Physical Forgetting Achieved

Users temporarily forgot they were sitting in a real chair, validating the mind-body disconnection goal

"If it was like five or six minutes, I would have forgotten that I was even sitting in a room"

External Control Worked

Autonomous camera movement increased rather than decreased immersion, confirming the counterintuitive finding

"I knew it wasn't real, but I was still being cautious to bend over because of the fear"

Key Takeaways

Research Uncovers Non-Obvious Insights

External control increasing immersion was counterintuitive — without research, I'd have assumed users need constant control, and the design would have failed.

Iteration is Non-Negotiable

Pilot testing revealed flaws invisible on paper — the tunnel view looked fine but failed completely in practice. Testing saved the project.

Technical Skills Amplify UX Work

Learning Unity meant I could implement my own ideas directly, making every iteration cycle faster.

Frameworks Enable Knowledge Transfer

Documenting the principles lets other designers apply these insights to their own projects, multiplying the research's value.

What I Learned About UX Design

This project taught me that great UX comes from rigorous methodology — research, synthesis into requirements, iterative design, and validation through testing. Pairing qualitative research with technical implementation (Unity, C#) made it possible to build evidence-based experiences that actually work.

Most importantly, users will surprise you. The external control insight, the weight of texture quality, the power of spatial contrast — none of it was obvious before research. Trusting the process over assumptions made all the difference.
