HoloMusic XP
2019 Website ↗

Personal project for my thesis in both my master's and computer engineering degree.

HoloMusix XP is an application that facilitates the learning of music and piano by using mixed reality and gamification techniques for the Microsoft HoloLens.

More details

HoloMusix XP leverages mixed reality to create an immersive environment for music education. The application uses gamification to motivate students and provides interactive feedback through the Microsoft HoloLens device.

🏆 FK Interactive Quiz System
2019 Website ↗

Developed as lead engineer at Furious Koalas.

A customizable quiz show system for live and hybrid events, enabling teams or individuals to compete on stage with real-time lights, sound, and interactive podiums.

More details

This system powers live quiz competitions inspired by popular TV formats. I was responsible for designing and implementing the core infrastructure: • Soldered and mapped LEDs for synchronized light animations. • Built a Node.js server to coordinate all game events: turn management, scoring, triggering lights and sounds, sending real-time updates to podiums via WebSockets, and controlling camera focus automatically. • Developed a Unity-based frontend for dynamic question display and visual effects. • Programmed Blackmagic camera controllers over the network for automated camera switching. • Designed and implemented the networking system for robust communication between all components. • Integrated a third-party system to allow audience participation via their mobile devices. The system supports both in-person and hybrid events, allowing the audience to interact live from the venue or remotely.

🍇 Fenavin Interactive Quiz Game
2019

Led, implemented, and installed this project for the Fenavin wine fair as lead engineer at Furious Koalas.

An interactive quiz game designed for trade fairs, featuring three different games with questions about wine. One game included aroma challenges linked to the quiz questions.

More details

The system consisted of two interactive screens, each powered by a Raspberry Pi, communicating with a central server. Each device ran a script to determine its role (viewer or player) and contest ID. The setup enabled dynamic, themed quiz experiences for attendees, including a unique aroma-based challenge. I was responsible for leading the project, developing the software, and deploying the system at the event.

🧠 Mindball, Mental Pulse Game
2018

Developed in collaboration with Carlos González for interactive events.

A competitive game using a brainwave-reading device. Two players wear headsets that measure their brain's electrical activity. The player with higher mental activity moves the ball toward their side. Designed for entertainment at fairs and events.

More details

This project integrates a brainwave sensor to create a unique competitive experience. Players compete by focusing their mental activity, which is measured and used to control a physical ball on the game field. The system was built using JavaScript and Python for device integration and game logic, LEGO MINDSTORMS for movement, and custom 3D-printed parts for the physical setup.

🤖 RoboTic
2018 Website ↗

Developed in collaboration with Furious Koalas and Telefónica as part of an educational innovation initiative.

An educational Unity game to teach kids robotics and programming.

More details

Project driven in collaboration with Telefónica. The main goal of RoboTIC is to facilitate and promote the learning of programming at early educational levels through the use of metaphors and advanced interaction devices. For this purpose, a 3D game has been designed and developed in which the player progresses through a series of puzzle-like levels, gradually acquiring basic programming knowledge. This gamification-based approach ensures that players have fun while learning. Additionally, real-world metaphors such as roads are used to represent programming mechanisms like expressions and loops. Interaction with RoboTIC is achieved using Augmented Reality techniques, overlaying virtual images onto the real world and enabling interaction with the physical environment. Specifically, the Microsoft Hololens device was used, representing the most advanced working environment currently available for Augmented Reality projects.
