PART I: TOPIC DEFINITION AND & THESIS AIM 1.1 Simple Topic Statement This project investigates how using Augmented Reality (AR) and Virtual Reality (VR) headsets hurts the human body. My main goal is to design a set of interior room rules and build a real, physical desk-and-chair system that moves with the user to stop them from getting hurt while they work in mid-air. 1.2 Purpose of the Study For Review 2, I need to prove to the faculty that this idea is backed by real facts. The goal of this document is to show that AR/VR is not just about making software or video games. When digital screens float in a real room, they create massive physical space and body posture problems. Those physical problems can only be solved by a trained interior and furniture designer.Fig 1 A dynamic design studio exploring the study of mixed reality user experience with physical furnitures & material systems
PART II: BACKGROUND: THE SHIFT FROM FLAT SCREENS TO 3D ROOMS 2.1 How Office Furniture is Changing Throughout history, furniture designers have had to invent new chairs and desks whenever technology changed. When computers first came out, designers had to invent the adjustable office chair and the standard 70 cm desk height so people could rest their arms and look down at a monitor. Today, technology is changing again. Instead of looking at a flat computer screen, professionals are wearing headsets (like Apple Vision Pro) that turn the whole physical room into a 3D workspace. Because the screens are floating in the air, users have to wave their arms around to click things. However, our current office chairs are still designed for the old 2D desktop computers. This creates a huge mismatch: the technology has moved into 3D, but our furniture is stuck in the past.Fig 2 Normal desk setup: comfortable and supported vs VR headset: Uncomfortable & not supprted.
PART III: WHAT WE ALREADY KNOW & THE BIG PHYSICAL PROBLEMS 3.1 The Three Major Health Risks From reading existing research, we already know that working in AR/VR spaces causes three major physical problems that interior designers need to fix: "Gorilla Arm" (Tired Shoulders): If you hold your arms up in the air to swipe at floating digital screens without resting your elbows on a physical desk, your shoulders will start burning with pain in less than 15 minutes. Severe Neck Pain: VR headsets are heavy on the front of the face. This weight pulls the user's head forward and out of a healthy upright posture. Over time, this causes extreme neck and spine pain. Bumping into Real Furniture: Standard office walking paths are about 1200 mm wide. But when someone is wearing a headset, their vision is partly blocked by digital objects. If they walk down a normal office hallway, they are very likely to bump into real desks or other people.Fig 3 Gorilla Arm fatigue accumulates during a prolonged use of mid-air interfacesFig 4 Vision Pro is reportedly becoming a real pain in the neck for Apple (and its testers)
PART IV: THE RESEARCH GAP & INDUSTRY OPPORTUNITY 4.1 The Methodological Void While software developers attempt to mitigate mid-air fatigue by altering digital tracking logic or resizing virtual buttons, there is a critical void in addressing these ergonomic failures through physical interior architecture and furniture design. Current Human-Computer Interaction (HCI) research treats the user as a floating entity, entirely ignoring the physical chair they sit in and the architectural space enclosing them. 4.2 Job Market Demand Companies like Meta, Apple, and Microsoft are hiring designers who understand both physical space and digital software. Big offices are starting to build "XR- ready" rooms, meaning there is a high demand for designers who know how to design these new types of workspaces.
5.1 Picking Materials That Don't Break VR Cameras To prove this is a real interior design project, the furniture and room finishes will be made of very specific materials. AR/VR headsets use tiny cameras to look at the room. If a room has shiny tiles or glass tables, the glare blinds the cameras and the headset stops working. Matte-Finish Desk Surfaces: The desk will be made of non-shiny, matte laminates. It will have a Light Reflectance Value (LRV) below 40 so the room's lights don't bounce into the headset's cameras. Memory Foam Armrests: The moving armrests will use thick memory foam and stretchy mesh to comfortably hold the user's arms while they wave them in the air. Metal Moving Joints: The chair will use strong aluminum metal joints (like a robot arm) so the armrests can smoothly follow the user's hands anywhere they reach in 3D space. PART V: PROPOSED MATERIALITY & PHYSICAL FABRICATION
6.1 My Step-by-Step Testing Plan To make sure my design actually works, I am going to run real tests on people during Review 4. I won't just guess; I will measure their pain using standard ergonomic rules. Testing Phase Ergonomic Metric Tools & Methodology Phase 1: Baseline Posture Neck & Trunk Breakdown Using the RULA (Rapid Upper Limb Assessment) method to measure neck angle changes over 20 minutes of XR use in a standard chair. A score of 5-6 indicates an immediate need for intervention. Phase 2: Upper Limb Fatigue Muscle Strain Limits Measuring the Consumed Endurance (CE) metric by timing how quickly users drop their arms during mid-air reach tests to determine the maximum unsupported interaction time. Phase 3: Anthropometric Translation Geometric Clearances Converting the failure points (e.g., maximum comfortable reach radius) into geometric AutoCAD dimensions to satisfy BIFMA G1-2013 office furniture standards (targeting an adaptive desk height range of 22 to 50 inches).

PART VIII: ISD RELEVANCE & TANGIBLE CAPSTONE OUTCOMES 8.2 Tangible Capstone Deliverables The final Capstone outcome will be delivered in two integrated phases to satisfy jury requirements and build a high-tier professional portfolio: The Physical Architectural Output (ISD Core): A 1:1 scale fabricated physical prototype of the kinetic armrest targeting upper-limb fatigue. This will be accompanied by GFC-level AutoCAD commercial interior layouts detailing buffer zones and modified spatial clearances for XR workflows. The Digital Simulation Output (XR Integration): An interactive 3D digital simulation built in Unity 3D to visualize the ergonomic reach envelopes and prove the physical chair's viability with digital interfaces.
