tutorials

September 30, 2025

Tutorial 1 – Visuo-Haptic Immersion Made Easy: A Fast-Track Course on Spatial Anchors

Mixed Reality (MR) occupies the midpoint of the Reality–Virtuality continuum, blending real and virtual elements into a unified environment, which can reach high levels of immersion by integrating spatial, visual, and haptic cues, preserving real-world awareness while convincingly embedding virtual content. A key driver of this experience is multisensory integration, where vision often dominates and shapes perceptions in other modalities, influencing tactile judgments and increasing the illusion of touch. To explore this visuo-haptic integration, this tutorial guides participants to design and implement a Meta Quest 3 application in Unity that harnesses Spatial Anchors to precisely align 3D models with physical objects. Through a combination of concise theoretical overviews and hands-on exercises—from environment scanning and anchor management to deployment—attendees will acquire practical skills to create, save, and interact with stable visuo-haptic experiences, leaving with a functional prototype and a clear development pipeline for Visuo-Haptic immersive applications

Target audience:

Virtual, Augmented and Mixed Realities (VR, AR and MR) enthusiasts that speak english and / or portuguese, to understand the content presentations and clarify their doubts at the guided activities. To achieve a better experience in this tutorial, the number of participants should be restricted to around 20 to 25 people. We intend to bring and use 5 Meta Quest 3 devices in this short course, in a way that we believe that a device per group of 5 people is enough for them to acquire the experience targeted by the tutorial.

The audience does not need any VR or Unity development background or previous Quest 3 usage to participate in this tutorial, as the present content aims to facilitate the application of real-virtual aligned elements, using spatial anchors, to enhance the visuo-haptic experience in MR applications, which can be useful to both beginner and advanced users.

People with severe vision impairments and motion blur sensitivity may have some discomfort level and present cybersickness symptoms. If a participant experiences any discomfort, they can leave the tutorial at any time.

Expected outcomes:

Through this tutorial’s experience, the participants will learn how to use Unity Engine with Meta Spatial Anchors to develop an application (APP) for Meta Quest 3 that enhances the immersion in the virtual environment, applying 3D Objects located at the physical elements’ real positions, to create their own MR personalized room, respecting the furniture dimensions and scales in a verisimilar way.

The participants could use the developed APP to personalize their environments with objects at their preferences, with some usages that extend to (although not limited to) a personalized visuo-haptic appealing room with different objects, or an educational environment, recreating a historic period’s room (e.g., an ancient rome atrium).

Tutorial 2 – Rapid VR Prototyping for Academia and Industry: A Tutorial on Building Interactive Experiences with Godot and the XR Tools Framework

It is a 3-hour tutorial focused on rapid prototyping of Virtual Reality (VR) experiences using the Godot Engine in conjunction with the Godot XR Tools framework. The tutorial aims to equip participants from academic and industrial backgrounds with a modern, efficient workflow, shifting the focus from low-level boilerplate coding to high-level VR design concepts and rapid iteration. By leveraging the pre-built functionalities of Godot XR Tools for common VR mechanics such as locomotion and interaction, participants can achieve significant results within a short timeframe. This approach not only accelerates development but also aligns with real-world practices where leveraging libraries and specialized tools is standard.

Target audience:

The tutorial is designed for a broad audience, including participants from both academic and industrial backgrounds who are interested in developing Virtual Reality (VR) experiences. The primary target groups are:

• Academic Researchers and Students: Individuals in computer science, human-computer interaction (HCI), and related fields who need to build VR prototypes for research, user studies, or educational tools. The tutorial offers a pathway to create functional experiments without the steep learning curves or licensing restrictions of other commercial engines.

• Industry Professionals and Indie Developers: Developers from small to medium-sized studios or independent creators seeking an efficient, open-source workflow for rapid prototyping and commercial development. The focus on the MIT-licensed Godot Engine and its tools ensures that all skills learned are directly applicable to commercial projects without legal or financial barriers.

• Beginners in VR Development: Participants with basic programming knowledge but little to no prior experience in VR. The tutorial is structured to build foundational knowledge from the ground up, starting with core engine concepts before moving to complex VR mechanics.

No prior experience with the Godot Engine is required, although a fundamental understanding of programming concepts is beneficial.

Expected outcomes:

Understand Core Godot Concepts: Participants will gain a solid understanding of Godot’s node-and-scene architecture, the GDScript language, the physics system (including ‘RigidBody3D‘, ‘StaticBody3D‘, and ‘Area3D‘), and the signal system for event-driven programming.

Set Up a Complete VR Project: Attendees will learn to configure a Godot project for VR from scratch using the OpenXR plugin, including setting up the necessary tracking space, camera rig, and controller representations.

Implement Standard VR Locomotion and Interaction: Participants will be able to implement common VR mechanics using the Godot XR Tools framework, including teleportation, direct movement, and turning. They will also master direct-grab interactions to pick up, hold, and release objects in the virtual world.

Build Interactive VR User Interfaces (UI): Attendees will learn the standard technique for creating diegetic UIs in VR by rendering 2D Godot scenes onto 3D surfaces and interacting with them using a controller-based laser pointer.

Develop a Complete Mini-Game Loop: By the end of the session, participants will have built a small, playable “Recycling Simulator” game. This capstone project integrates all the concepts taught, reinforcing their understanding of physics, interaction, and event-driven logic in a practical context.

Apply a Rapid Prototyping Workflow: The most significant outcome is the acquisition of an efficient workflow that shifts the focus from low-level boilerplate coding to high-level interaction design and rapid iteration. This empowers them to quickly test ideas and build functional prototypes for research or commercial purposes
