HOLOTOUR

Traveling with mixed reality

A pioneering experience

With HoloTour, we paved the way for a new way to experience the world through mixed reality. Developed for the HoloLens headset, this application allows users to visit iconic sites such as Rome or Machu Picchu from home, combining 360° panoramic videos, interactive holograms, and spatial audio.

At the time, it was a unique project: Microsoft trusted us to push the technical boundaries and bring to life one of the very first real-world applications of mixed reality. HoloTour remains today a milestone in the history of immersive experiences.

A project that marked a turning point

HoloTour was not just a technological showcase, it was an experience designed for the general public: to travel, learn, and feel.
Guided by Melissa, a holographic tour guide, users explore monuments, listen to historical anecdotes, and discover places as if they were truly there.

What makes HoloTour unique:

  • High-quality 360° videos: captured with a 14-camera rig to reproduce space from every angle.
  • Interactive holograms: adding depth, parallax, and motion to enhance immersion.
  • Spatial audio: every sound and voice is naturally positioned in space.
  • Adaptive interaction: the system detects where the user is looking and enriches the content in real time.
  • Freedom of movement: the more you explore, the more you discover.

HoloTour demonstrated early on the potential of mixed reality for fields such as:

  • Culture and museums: making heritage more accessible and alive.
  • Tourism: offering immersive previews and showcasing unique sites.
  • Education: learning differently, through immersion that enhances memory and attention.

This project also helped establish technical standards still used today:

  • Synchronization of 360° video and spatial audio.
  • “Impossible perspectives” (e.g., a hot-air balloon flight over Rome).
  • Software optimizations to ensure a smooth experience on HoloLens.
