I'm Dr. Yasas Sri Wickramasinghe — a Postdoctoral Researcher at HIT Lab NZ (University of Canterbury) and Senior Lecturer at Yoobee College of Creative Innovation. I hold a PhD in Human Interface Technology, with a dissertation on designing multiplayer location-based AR games that connect remote players and places. My work is conducted with industry partners including Sony Interactive Entertainment (Japan) and Niantic, Inc. Earlier I co-founded NavitaZ VR Labs under the MIT Global Startup Labs programme and led Sri Lanka's first large-scale MOOC platform. Research partners: HIT Lab NZ, Sony Interactive Entertainment, and Niantic Spatial. **Academic Platform — work with me directly.** Consultations, speaking invitations, writing, and a student community, in one place, at yasassri.me/app: Book a Free Consultation (30–45 min on education, research or career guidance, no charge) — Invite Me to Speak (signature talks, a ready-to-use speaker kit, and invitations, at yasassri.me/speaking.html) — Read the Blog (writing on HCI, AR/VR, software engineering and education) — Join the Forum (ask questions, help peers, stay connected as a community). **Three research frontiers.** (1) Location-Based AR — designing multiplayer AR experiences that meaningfully connect remote players to real-world places. (2) Spatial Computing & XR — studying how immersive interfaces reshape cognition, trust, and decision-making in shared spaces. (3) Player Experience & HCI — evaluating how people feel, behave, and collaborate inside the systems we design and deploy. Research notes, occasionally: notes on immersive media, spatial computing, and lessons from building XR — a few times a year. **Selected work.** Representing Remote Locations with Location-Based AR Game Design — Entertainment Computing, Elsevier, 2025. A multiplayer location-based AR system, designed and evaluated with Sony Interactive Entertainment, exploring how players experience and represent distant real-world places together — published across leading HCI venues. **New book — The Collaboration Reflex.** "Why the 'right' answer to conflict is usually wrong." Conflict shows up in every team, every project, every workplace — and almost everyone reaches for the same answer: collaborate, find the win-win. This book argues that reflex is usually wrong, using forty-five real, anonymised workplace conflicts to show when collaboration works, when it backfires, and what to do instead.

Campus Ready (https://ictcampus.lk/campus-ready) is ICT Campus's second initiative: a 12-week programme, taught in Sinhala, for students waiting between their A/Ls and university. It covers Word, Excel, Python, statistics, Power BI, referencing, Zotero and ethical AI use, ending in a capstone dashboard on real Sri Lankan open data and a graded, verifiable certificate (issued by ICT Campus; not university-accredited). Intakes in January and July; first intake January 2027. --- ## Research — https://www.yasassri.me/research.html Connecting players & places across distance. My research designs, builds, and evaluates location-based augmented reality games that let physically separated players share a single augmented space. Through a research-through-design approach, I study how AR can move beyond decoration to become a core mechanic — reframing place itself as a shared, interactive canvas across distance. **The driving question.** "How can augmented reality make meaningful use of the real world to facilitate synchronous remote multiplayer gameplay?" Most location-based AR games treat AR as an optional visual layer — players can often switch it off without changing the game. My doctoral research asks the opposite: what happens when AR becomes the mechanism that binds remote places and players together? I answer this across three empirical user studies, organised around three research questions on representing remote space, spatial decision-making, and interactive AR mechanics. Snapshot: 3 empirical user studies, 128 study participants, 5 peer-reviewed articles, 4 design-guideline themes. **Doctoral thesis.** "Designing Multiplayer Location-Based Augmented Reality Games that Connect Remote Players and Places" — PhD, University of Canterbury, HIT Lab NZ. Supervised by Prof. Stephan Lukosch, A. Prof. Heide Lukosch, and James Everett, this thesis uses an iterative research-through-design method — cycles of design, development, and evaluation — to investigate how AR can represent remote spaces, support spatial decision-making, and drive engagement through core game mechanics. The work spans five peer-reviewed publications (Articles I–V) and contributes theoretically, empirically, methodologically, and practically to the design of remote multiplayer AR games. UC Research Repository: https://ir.canterbury.ac.nz/items/6df971c0-1314-4863-8156-304c838686d0 **Three studies.** Study 01 (RQ1) — Representing Remote Spaces: compared three AR techniques — Overlay, Window, and Tabletop — for portraying a remote location. Overlay produced the strongest sense of "being there" and self-location; Window felt like the remote place extending into your own; Tabletop offered a detached strategic overview. 30 participants; Entertainment Computing. Study 02 (RQ2) — Decision-Making & Experience: a remote multiplayer AR hide-and-seek game compared against co-located play. AR shifted spatial strategies — players exploited mid-air and vertical space — and a lightweight frustum cue strengthened social connection without avatars or video. 60 participants; IEEE VR, MDPI MTI. Study 03 (RQ3) — Mechanics & Constraints: introduced interactive core AR mechanics — real-time object manipulation, particle-effect feedback, and time pressure. These deepened strategic search behaviour and engagement when paired with clear feedback and well-calibrated constraints. 38 participants; OzCHI 2025. **Design guidelines.** (1) Remote Space Representation — make the place feel present: prioritise real-world-scale Overlay views for spatial presence, use Window "portals" as an intuitive interface for sharing resources between locations, ground it all in high-fidelity 3D scans of the remote environment. (2) Player Interaction & Coordination — lightweight presence beats fidelity: visualise the remote player's viewpoint in real time and add voice; minimal orientation cues (a frustum avatar) coordinated players as effectively as far heavier embodiment. (3) AR Mechanics & Constraints — AR as a core mechanic: embed AR in the gameplay loop rather than as decoration — multiple remotely anchored objects, real-time manipulation, carefully calibrated time pressure. (4) Engagement & Spatial Decisions — guide without removing the challenge: subtle feedback (like particle trails marking object swaps) supports orientation while preserving discovery; support onboarding to reduce early disorientation; design for player safety during physical movement. **Other projects.** Trust in Shared Augmented Reality (ACM SUI 2024) — investigating how design choices shape trust when users exchange virtual items in shared AR environments; a 36-participant study presented at the ACM Symposium on Spatial User Interaction 2024. NavitaZ VR Labs (2015–2019) — co-founded an AR/VR startup under the MIT Global Startup Labs programme; built mobile AR apps and VR web applications in Sri Lanka; Microsoft Imagine Cup Runner-Up 2015. **Publication index.** 2025 — Evaluating Spatial Decision-Making and Player Experience in a Remote Multiplayer Augmented Reality Hide-and-Seek Game.

I design experiential, technology-forward classrooms — and build the platforms that power them. My Master's programme teaching is inseparable from the state-of-the-art learning management system I built to bring attendance, live coding, competitive SQL, and AI-assisted reasoning into every session. **A state-of-the-art learning management system — the platform I built.** A real-time learning platform: a full-stack web application I designed and built from scratch for the Master of Business Informatics (MBI) courses I teach. It replaces static slide decks and paper registers with a live, interactive, data-driven classroom experience. Every feature was shaped by a real classroom problem — from fraudulent attendance submissions caught by three detection algorithms, to students competing on SQL queries in real time. Stack: React 18, TypeScript 5, Vite 5, Tailwind CSS 3, Firebase Auth, Firestore, Firebase Storage. Open-source on GitHub (github.com/ureshan2011). Snapshot stats: 228 students across 3 courses, 24 countries in cohorts, 2,500+ attendance records logged, 100+ quiz MCQs and 16 lecture videos. Features: One-tap Attendance with fraud detection — students check in with a single tap; three detection algorithms run in real time to flag dishonest submissions: shared-IP clustering (multiple students on one device), GPS outlier detection (coordinates >500 m from campus), and a rapid-submission window (check-ins within 30 s of session open). Live Playground — an in-browser code execution environment embedded directly in lectures; students write and run SQL, Python snippets, and pseudocode without leaving the platform. SQL Race — students race around a virtual track by solving SQL challenges in sequence: SELECT → WHERE → JOIN → GROUP BY → ORDER BY → HAVING; a live leaderboard drives friendly competition. Quiz Badges — over 100 MCQ questions across all three MBI courses; students earn badge tiers as they progress, with instant feedback and explanations. Daily Match — a daily collaborative challenge pairs students across cohorts to solve a shared problem together, building cross-cultural communication skills across 24 countries. Cohort Analytics — a lecturer-only dashboard surfaces attendance trends, quiz completion rates, country-level engagement, and fraud alert history. **SQL Race — feature spotlight.** SQL Race transforms database exercises into a live, multiplayer competition. Each checkpoint on the track corresponds to a core SQL clause. Students only advance by writing a correct query. It was born out of a simple observation: students who were bored by textbook drills became intensely focused the moment there was a leaderboard. Checkpoints: 01 Select (basic column retrieval), 02 Where (row-level filtering), 03 Join (multi-table relationships), 04 Group By (aggregation logic), 05 Order By (result sorting), 06 Having (post-aggregation filter). **MBI course catalog** (Master of Business Informatics, New Zealand). MBI800 — Business Information Systems (Strategy & Systems Planning): the strategic role of information systems in organisations — IS alignment and SISP (Strategic Information Systems Planning), digital transformation frameworks, Porter's competitive models. Platform feature: SISP Prompt Lab — an AI-assisted tool embedded in the LMS that walks students through strategic IS planning exercises using guided prompts and real case data. MBI802 — Database Management Systems (SQL, ER Modelling, NoSQL): a hands-on deep-dive into relational database design, SQL from basics to advanced joins and stored procedures, ER diagram methodology, normalisation theory, and an introduction to NoSQL paradigms. Platform features: SQL Race (competitive live query challenges) and Live Playground (in-browser SQL execution environment). MBI804 — IT Project Management (Agile, Scrum, Risk): the full project lifecycle — initiation, planning, execution, monitoring, and closure — with a strong practical emphasis on Agile methodologies, Scrum ceremonies, stakeholder management, and risk frameworks. Platform feature: Case Study Labs — students manage a simulated IT project via the LMS, tracking sprints, updating risk registers, and submitting deliverables with structured peer review. **Teaching philosophy.** My approach to education is grounded in experiential and constructivist learning — I believe students learn best by building, failing, iterating, and reflecting. Every feature in the LMS was designed around this principle: the Live Playground lowers the barrier to trying, SQL Race makes failure feel like just one more lap, and badge tiers reward persistence over perfection. I prioritise purpose-driven education: helping students not just acquire technical skills, but develop the vision and initiative to use them meaningfully. In a classroom spanning 24 countries, that also means building cultural fluency and collaborative communication into every assignment. "If we can change the way we see the world, we can change the world we see." Availability: Mon–Sat, 10:00–17:00, in-person / virtual, at Christchurch, NZ, for mentoring, supervision, and industry talks. **Previous teaching.** 2021–2022 — Computer Architecture & Enterprise Software, University of Moratuwa, Sri Lanka. 2018–2021 — Database Management Systems, SLIIT & University of Moratuwa, Sri Lanka. 2018–2022 — Human-Computer Interaction, University of Moratuwa & SLIIT, Sri Lanka. 2018–2022 — Project Management & Enterprise App Development, SLIIT, Sri Lanka.

I was also a visiting lecturer at NSBM Green University, SLIIT and the Institute of Technology, University of Moratuwa (ITUM), and Platform Lead for the Software Engineering strand of the University of Moratuwa's open learning platform (open.uom.lk), which reached 150,000+ registered learners. Today I teach A/L ICT to Grade 12 and 13 students in Sri Lanka through ICT Campus (https://ictcampus.lk), the online classroom I founded. Classes are live, in Sinhala and English medium, and follow the NIE syllabus. Free study material, no account needed: the A/L ICT syllabus (https://ictcampus.lk/syllabus), past papers (https://ictcampus.lk/past-papers), short notes, exam command words, logic gates, number systems and a revision plan. For the wait between A/Ls and university: Campus Ready (https://ictcampus.lk/campus-ready), a 12-week course, plus free guides on what to do after A/Ls (https://ictcampus.lk/after-al), the Z-score (https://ictcampus.lk/z-score), university Z-score cut-offs (https://ictcampus.lk/z-score-cutoffs), the UGC application, APA referencing and using AI in assignments.

Four lifecycles drawn rather than described, a change dragged along the cost-of-change curve, Boehm’s spiral walked loop by loop, PRINCE2’s seven principles, themes and processes opened one at a time, then the whole Agile family — and Scrum in full: a clickable framework diagram, twelve “whose job is this?” situations, timeboxes that scale with the Sprint, and a board with a live burndown. - The Scrum studio: a Sprint you can watch, pause and orbit (Lesson): https://www.yasassri.me/lessons/scrum-simulation.html (interactive: https://ureshan2011.github.io/thisisnotalms/#/scrum-simulation) — Lesson 3. Six 3D miniatures build a parcel drone through three one-week Sprints while a caption says what is happening and a timeline marks every milestone: the Product Backlog ordered on the wall, refined and estimated with Planning Poker, Sprint Planning pulling cards into the Sprint Backlog, a fifteen-minute Daily Scrum every morning, an impediment landing and being cleared, stakeholders watching the drone lift off at the Review, one improvement from each Retrospective. Voice-narrated, it pauses after each step so you can read, then a seven-question check. - The outside auditor: peer audit round (Practice): https://www.yasassri.me/lessons/peer-audit.html (interactive: https://ureshan2011.github.io/thisisnotalms/#/peer-audit) — The class swaps post-mortems — you audit a project you did not run, and nobody gets their own back. Practise the four audit questions on a fictional scenario whose author is confident and wrong about all of them, sort eight sentences into restating, asserting and auditing, choose a risk response where mitigating is the wrong answer, then build the one-page Corrective Action Plan and export it. - Project cost management (Lesson) (currently offline on the lessons site): https://ureshan2011.github.io/thisisnotalms/#/cost-management — Plan, estimate, budget — and avoid the traps that sink most IT projects. Seven interactive sections around the SecurePay NZ scenario: PERT calculator, budget builder, live S-curve and a closing challenge. - The collaboration reflex (Lesson): https://www.yasassri.me/lessons/collaboration-reflex-lecture.html (interactive: https://ureshan2011.github.io/thisisnotalms/collaboration-reflex-lecture.html) — Conflict and communication management taught through forty-five real, anonymised classroom conflicts: six full stories, four frameworks, and the one reflex experienced professionals reach for even when it is the wrong answer. - Conflict swap (Practice): https://www.yasassri.me/lessons/conflict-swap.html (interactive: https://ureshan2011.github.io/thisisnotalms/conflict-swap.html) — Write a real conflict you have lived through, anonymously.

Key concepts drift like a galaxy, then swarm together to reveal the course code right as we begin. --- ## Studying a master's in New Zealand — https://www.yasassri.me/students.html "Studying a master's in New Zealand: what I tell my students." A long-form guide by Dr. Yasas Sri Wickramasinghe, written as experience sharing from a lecturer who teaches master's students in New Zealand (information systems strategy, database management, IT project management and business analytics in a Master of Business Informatics programme, Christchurch and Auckland) and who came to New Zealand from Sri Lanka as a postgraduate student himself. It is not official advice and gives no visa or immigration advice; it points readers to Immigration New Zealand or a licensed adviser for that, and to the institution they apply to for admissions and fees. Covers: taught vs research master's (Level 9 on the NZQF); what a week looks like (one NZ credit is designed around ten learning hours, so a 15-credit course expects about 150 hours, most of it independent study); project-based assessment (a strategic plan, a working database, a simulated project) and reading the rubric first; the classroom culture shift (discussion, first names, critical thinking); academic writing and APA 7, with the common referencing mistakes; academic integrity and generative AI (follow each course's rules, never submit AI text as your own, declare use, be able to explain everything); group work in international classes (students from more than twenty countries across his cohorts); eight habits of students who do well; questions to ask when choosing a programme; and free lessons to try before applying. Ends with a nine-question FAQ and a free 30-minute educational guidance chat (yasassri.me/app/#/consult?type=education). --- ## Web Products — https://www.yasassri.me/products.html Research-grade thinking, shipped as software. Beyond the lab, I design and build full-stack web products that put data, machine learning and clean UX in front of real users.

Estimates are indicative, not registered valuations, and not financial advice. Live: https://ureshan2011.github.io/HouseScout/ **PathFinder** (Live · Study Planning, New Zealand · Static Web, Client-side). A planning platform for Sri Lankan students applying to master's and PhD study in New Zealand. Applying for postgraduate study abroad means piecing the answer together from a dozen half-reliable sources — agent blogs, forum threads, PDFs three years out of date. PathFinder puts the whole route in one place: what you qualify for, what it really costs, the visa, and the move. Key features: seven-stage tracker from assessment to first week; a five-minute readiness assessment that generates a personalised month-by-month timeline; 1,716 current NZQF level 8 and 9 qualifications, searchable by subject, provider and level; 51 providers across 11 subject areas; a cost calculator in NZ$ and rupees covering tuition, living costs and visa funds; visa deadlines and settlement guidance; 281 scholarships and funding sources; mentors already studying in New Zealand. Value: replaces guesswork and agent fees with the published record — real entry requirements from the NZQA register, real fees, real visa thresholds — so a student can see in five minutes whether the route is open to them, and what the next month should look like. Free to start, no account needed. An independent tool built from published sources; not affiliated with NZQA, Immigration New Zealand or any provider, and not immigration advice. Live: https://ureshan2011.github.io/Pathfinder/ **Faro** (Travel · Python, Machine Learning). A flight-fare timing assistant that answers the one question every traveller has: book now, or wait? Faro tracks prices across airlines and uses a model trained on route-specific history to give a clear, daily Book/Wait call. Key features: daily fare monitoring across airlines; clear "Book now" vs "Wait" recommendation; ML trained on route-specific price history; full flight details (airline, stops, times); refreshes several times a day; aggregates fares from Google Flights; live weather & currency context; open, publicly accessible underlying data. Value: flexible travellers save money by booking in the optimal window, guided by predictive modelling instead of gut feel. A personal build; not publicly hosted. **How these are built.** Full-stack web — end-to-end builds in Python and TypeScript, from data layer to a clean, responsive interface. AI & machine learning — predictive models and local LLMs wired into products. Data pipelines — aggregating and cleaning real-world data (listings, fares, weather, currency) into something dependable. Product UX — designing focused interfaces that make a complex decision feel simple and trustworthy. **FAQ.** Q: Who built HouseScout, PathFinder and Faro? A: All three products were designed and built by Dr. Yasas Sri Wickramasinghe, a researcher, university lecturer and software developer based in Christchurch, New Zealand.

Faro is a personal build and is not publicly hosted. Q: What technologies are these products built with? A: HouseScout and Faro are built with Python, with Faro also using a machine-learning model for price prediction. PathFinder is a static browser application with no backend — the assessment, cost calculator and NZQA programme catalogue all run client-side. Q: What does HouseScout do? A: HouseScout is a property-buying dashboard for Christchurch home buyers. It tracks listings against user-defined criteria, surfaces indicative valuations and market insights, includes a buying-journey planner, and offers a private local AI assistant powered by the Gemma model. Estimates are indicative, not registered valuations, and not financial advice. Q: How does Faro decide whether to book a flight or wait? A: Faro uses a machine-learning model trained on route-specific historical fares to predict how a price is likely to move, then gives a clear "Book now" or "Wait" recommendation. It monitors fares across airlines and refreshes several times a day. Q: Who is PathFinder for? A: Sri Lankan students planning a master's or PhD in New Zealand. It covers the whole route in one place — a five-minute readiness assessment, a searchable catalogue of 1,716 current NZQF level 8 and 9 qualifications from 51 providers, real tuition, living and visa-funds costs in NZ$ and rupees, 281 scholarships, and mentors already studying in New Zealand. Q: Where can prospective MBI students learn more? A: See his guide for prospective students (yasassri.me/students.html) for MBI programme facts, his teaching approach, and a free consultation link — his own account as the lecturer who teaches the programme, not an official college page. --- ## News — https://www.yasassri.me/news.html On stage, in the field & in the news.

Three studies: Study 1 (30 participants) compared Overlay, Window and Tabletop views of a remote room — Overlay gave the strongest sense of being there; Study 2 (60 participants) ran a remote multiplayer AR hide-and-seek game — a lightweight view-frustum cue strengthened social connection without avatars or video, and players used mid-air and vertical space; Study 3 (38 participants) showed interactive AR mechanics deepened strategic search and engagement when paired with clear feedback and calibrated constraints. Published across five peer-reviewed articles including IEEE VR, OzCHI and Elsevier's Entertainment Computing. **A state-of-the-art learning management system: a classroom students don't want to skip.** A learning platform he designed and built for the Master of Business Informatics courses he teaches: one-tap attendance with three fraud checks (shared-IP clustering, GPS outliers more than 500 m from campus, check-ins within 30 seconds of opening), a live SQL/Python playground, SQL Race, quiz badges, daily cross-cohort matches and lecturer analytics — used by 228 students from 24 countries, with 2,500+ attendance records. Four courses were then rebuilt as 39 interactive lessons, labs and study packs. **ICT Campus: building a bilingual online school.** Founder, lead teacher and developer of ictcampus.lk — live Zoom classes with recordings, real-time chat, timed mock exams and a browser Code Lab covering the full NIE A/L ICT syllabus in Sinhala and English; free public study pages; and Campus Ready, a 12-week programme for students waiting to start university. ## The Location-Based AR Design Playbook — https://www.yasassri.me/playbook.html A free playbook of four evidence-based principles for location-based AR that connects people across distance, from three user studies with 128 participants at HIT Lab NZ. (1) Make the place feel present — use a real-world-scale Overlay for presence and self-location, Window portals for passing resources between locations, and high-fidelity 3D scans of the remote space (Study 1, Entertainment Computing 2025). (2) Lightweight presence beats fidelity — show the remote player's viewpoint in real time, pair it with voice, test minimal cues like a view frustum before investing in avatars, and design for vertical and mid-air space (Study 2, IEEE VR 2025 and MDPI MTI 2025). (3) Make AR a core mechanic — embed AR in the gameplay loop with remotely anchored objects, real-time manipulation and time pressure calibrated in playtests (Study 3, OzCHI 2025). (4) Guide without removing the challenge — subtle feedback such as particle trails, onboarding for the first minutes, and design for safe physical movement.

Bio, photos and a media-request form are on the page. ## About — https://www.yasassri.me/about.html From Colombo lecture halls to Christchurch labs. He studied IT at the University of Moratuwa (2013–2017), was a Microsoft Imagine Cup runner-up (2015) and co-founded the AR/VR start-up NavitaZ VR Labs under the MIT Global Startup Labs programme (2015–2019). He spent four years as a technical lead and senior software engineer at 99X, lectured at the University of Moratuwa (2018–2022) and led the Software Engineering strand of its open learning platform (150,000+ registered learners), then completed a specialisation in virtual reality at Goldsmiths, University of London. In 2022 he moved to New Zealand for a fully funded PhD at HIT Lab NZ, University of Canterbury (2022–2025), researching multiplayer AR with Sony Interactive Entertainment and Niantic. Today he is a Postdoctoral Researcher at HIT Lab NZ, a Senior Lecturer at Yoobee College of Creative Innovation, the founder of ICT Campus and the author of The Collaboration Reflex. What he believes: measure before you argue; build, test, repeat; and good teaching shouldn't depend on where you live. ## NZGDC 2026 talk — https://www.yasassri.me/nzgdc/ Designing Shared Worlds Across Distance: Lessons from Multiplayer AR Game Research. Delivered at NZGDC 2026 on Thursday 1 October 2026, 3:00–3:30 PM NZDT, NZ International Convention Centre, Auckland. What three multiplayer AR games and 128 players taught him about playing together from apart. The 30 slides are a free PDF download: https://www.yasassri.me/assets/files/nzgdc-2026/shared-worlds-across-distance-slides.pdf **The problem.** Pokémon GO has grossed around US$9 billion in ten years, yet only about 7% of surveyed location-based game players regularly used the AR camera (Laato, Inaba & Hamari, 2021) — the main reason: "As it is slower to use, I prefer not to." Remote play (Remote Raids) arrived in 2020, when player spending passed US$1B in the first ten months (Sensor Tower), but let players act on a place without being there. The research question: how can AR make meaningful use of the real world for synchronous remote multiplayer play? Built in Unity with Niantic Lightship ARDK on LiDAR iPads, rooms scanned with Scaniverse, with input from Niantic's Wellington studio, measured with questionnaires, Tobii eye-tracking glasses, ceiling cameras and interviews. **Game 1 (30 players): Tabletop, Window or Overlay?** Overlay (the remote room at 1:1 around you) was preferred by 67% and was the only mode with a significant lift in feeling present; Window was the most usable, players called it "the portal", and 8 of 30 tried to walk through it; Tabletop had one fan. Rule: scale changes presence. **Game 2 (60 players): remote AR hide-and-seek vs real hide-and-seek.** In the AR version the two players were in separate rooms. AR hiders used ceilings and mid-air; hiding took ~40% longer (72s vs 52s), the "fun" score rose (2.0 vs 0.6 on −3…+3), finding time showed no significant difference, and 32 of 60 lost track of time. The bright yellow Minion was chosen 15× in AR versus once in real life (bold objects 1.6× more often) because fiddly thumbstick placement made players optimise for the controls. A moving view-cone plus voice created togetherness: 16 players said the cone was enough, 10 wanted an avatar; strangers cut verbal hints by a third in AR, friends did not. **Game 3 (38 players): AR-only mechanics.** Resize and camouflage, multi-object clones, active swapping (with a particle trail for fairness) and time pressure. One object with no timer gave the highest reward and ease of use; three objects with no timer the highest engagement; timer plus swapping the most fun and deepest immersion but the hardest to learn. Players split almost evenly (9 vs 8) on wanting a timer. **Six rules.** (1) If players can switch the AR off, it isn't a mechanic yet. (2) Scale changes presence. (3) Break physics on purpose. (4) A view-cone and voice go a long way. (5) Players adapt to your controls first. (6) Let players choose the pacing. Limitations: thumbstick placement, Overlay needs an empty room (3 disoriented), arm fatigue (4), a learning curve for swapping, lag and drift, and first-session data only. ## Contact — https://www.yasassri.me/contact.html Inquiries & correspondence.
