The scented cookbook is a mini project created over two days during the Tangible Interaction course at the University of Oslo. The theme for this project was Olfactory Interaction - interaction that involves scent.
This scented cookbook combines the art of culinary exploration with sensory engagement. It features a unique design that integrates two diffusers. As users flip through the pages, the diffusers release fragrances that correspond to the recipes being explored.

We spent about two hours brainstorming around the theme, generating various ideas, and jotting them down on post-it notes. After categorizing the ideas, we chose the one we all liked best, keeping the time constraints in mind. Once we decided on the concept of a cookbook, we started drawing up a few sketches and quickly moved into prototyping with foam board before transitioning to the technical development phase.
The technical aspect of the project focused on getting two diffusers to work with an Arduino, activated based on the page being viewed. Additionally, we needed to determine the best material for the pages.
THE PROCESS
Ideation
DESIGN
From concept to design
We also had to experiment with creating the scents. For the cinnamon scent, we boiled cinnamon powder in water to capture the desired fragrance. For the lemon dressing, we used lemon essence and boiled garlic to recreate the scent. We carried out tests with individuals of varying scent sensitivity to evaluate the effectiveness of the aromas. It took a few tries to achieve the perfect scents!
TESTING
Finding the perfect scent
We decided on wood for the pages to ensure they had enough weight for our sensors to register correctly. Using a laser cutter, we crafted both the pages and the box housing the Arduino and diffusers. The cover of the cookbook was also laser cut and engraved from acrylic, adding a polished, durable finish to the design.
RESULTS
The exhibition
The scented cookbook was showcased in the Olfactory Interaction mini exhibit. It features two recipes: Cinnamon Buns, which fills the air with a warm, inviting cinnamon scent, and Lemon Dressing, offering a refreshing lemon aroma with a subtle hint of garlic. This multisensory approach enhances the cooking experience by immersing users in the delightful aromas of the dishes, making the act of cooking more enjoyable and engaging.
Final Takeaways
Through this project, I learned how much can be achieved in a short time frame, as we successfully brought the scented cookbook to life in just two days. I gained hands-on experience with a range of tools and programs, from laser cutting to working with Arduino. Additionally, experimenting with both technical and sensory elements—like crafting scents and designing interactive components.
