In-Book™ Books
These titles are concept applications of the In-Book™ technology — not available books yet. All are compatible with the same spine. Only 'The Worlds of Lulu' exists as a working prototype.


The Animal Kingdom
Lions, eagles, turtles, wolves — immerse yourself in the richness of the animal world with sound effects and vibration synced to the most dramatic moments.

The Worlds of Lulu
Lulu is a 10-year-old girl who discovers a way to travel to infinite worlds — a quest to unveil the secrets surrounding her mother's mysterious disappearance. First chapter of an ongoing collection.

Volcanoes · Wild Nature
Feel the eruption. The vibration motor and sound effects put you at the heart of the world's most active volcanoes.

The Human Body
Hear the heartbeat, feel the pulse through vibration, and watch the body's systems light up before your eyes.

Origins of Music
From ancient drums to the first guitars — feel the rhythm of history through sound and vibration synced to every chapter.

Amazing Universe
Explore black holes, nebulae and distant galaxies with immersive light and sound effects that bring the cosmos to life.
Only "The Worlds of Lulu" currently exists. The rest are concepts for future titles.
All compatible with the same spine
Purchase the In-Book™ Spine once. It works with every book in the collection and with titles added in the future. Each book's programme is integrated into its pages via a microchip.
Tested in the real world.
The Worlds of Lulu is a fully functional prototype of the In-Book™ system. The complete multisensory experience — light, sound and vibration — has been tested in real reading situations with children. The results validate the concept and confirm the demand for new titles.
