- [Research](https://www.yasassri.me/research.html): Peer-reviewed publications in AR, XR and HCI, with venues, DOIs and links (IEEE VR, ACM SUI, OzCHI, Elsevier Entertainment Computing, MDPI).
- [Teaching](https://www.yasassri.me/teaching.html): Postgraduate teaching in information systems and project management; gamified, high-engagement courses; thesis and capstone supervision.
- [For Prospective Students](https://www.yasassri.me/students.html): His own account, as the lecturer who teaches it, of the Master of Business Informatics (MBI) programme at Yoobee College of Creative Innovation — course details (MBI800/802/804), his teaching approach, and a free "Educational Guidance" consultation for prospective students. Explicitly not an official Yoobee College page; it says so on the page.
- [Web Products](https://www.yasassri.me/products.html): Portfolio of software he has designed and built — HouseScout, PathFinder, and Faro.
- [News](https://www.yasassri.me/news.html): Upcoming events (NZGDC 2026 talk, 1 October 2026; ICITR 2026 Workshop 01, University of Moratuwa, date to be announced), recently delivered workshops (Code Champ 2026 Workshop 07, 20 August 2026; CODE with WIE 2026 workshop, 11 July 2026), invited talks, media, international collaborations (e.g. Tohoku University research visit, Falling Walls Lab NZ), and how to invite him for a talk or workshop.
- [Try AR](https://www.yasassri.me/ar.html): An interactive, beginner-level augmented reality playground that runs in a phone browser with no app or download — tap to hang a virtual object in the air, turn away, and find it again. Built as the companion page for Code Champ 2026 Workshop 07. Uses only a camera feed plus the gyroscope (no WebXR, no ARCore, no plane detection), and degrades to a drag-to-look camera mode and then a plain 3D animation, so it works on low-end phones and slow connections. Also hosts annotated clips of Niantic Lightship experiments (scene meshing; semantic segmentation, plane detection and occlusion; location-based AR; shared AR) and diagrams explaining the multiplayer AR hide-and-seek game study.
- [Writing](https://www.yasassri.me/blogs.html): Essays on AR, spatial computing, and software engineering.
- [Contact](https://www.yasassri.me/contact.html): For research collaborations, guest talks, and consulting.
- [Platform](https://www.yasassri.me/app/): Interactive academic platform — free consultation booking (education, research, career mentoring), speaker-invitation requests with a talk-topics catalogue, blog, newsletter signup, and a student community forum.

Tracks listings against user-defined criteria, shows a metrics dashboard, offers indicative valuations and market insights, a buying-journey planner, and a private local AI assistant (powered by the Gemma model). Built with Python. Live and publicly usable. (Estimates are indicative, not registered valuations; not financial advice.)
- [PathFinder](https://ureshan2011.github.io/Pathfinder/): A planning platform for Sri Lankan students applying to master's and PhD study in New Zealand. Covers the whole route in one place: a seven-stage journey tracker from assessment to first week, a five-minute readiness assessment that generates a personalised month-by-month timeline, a searchable catalogue of 1,716 current NZQF level 8 and 9 qualifications from 51 providers across 11 subject areas with published entry requirements, a cost calculator for tuition, living costs and visa funds in both NZ$ and rupees, 281 scholarships and funding sources, visa and settlement guidance, and a mentor network of Sri Lankan postgraduates already studying in New Zealand. A static browser application — everything runs client-side. Free to start, no account needed, live and publicly usable.
