Desserts that can compute their own flavours

An interesting new research project from Monash University is creating a ‘cyber’ food experience that combines logic operations — the basic building blocks of every digital computer — with edible materials, resulting in the creation of a liquid-centred dessert.

The Logic Bonbon system includes a pre-made hollow bonbon with the option of three different ‘logic gates’ that allow the flow of flavoured liquids into the bonbon.

Users can introduce different liquids into the bonbon simultaneously and the bonbon is filled with different flavour and colour combinations depending on which ‘logic gate’ was used. The Bonbon also has a transparent top layer which allows the users to see their final results.

Food designer turned human-computer interaction researcher, lead author Jialin Deng, from the Faculty of Information Technology’s Exertion Games Lab, said the idea behind the development of the Logic Bonbon was to use food itself as an integral part of the computational operation.

“Over the course of three months, we tested the system with 10 participants, allowing them to sense, experiment and ‘play’ with the Logic Bonbons, filling it with different flavour combinations which they could consume,” Deng said.

“Through their interactions with the Logic Bonbons, the participants tangibly experience and learn about logic operations and are essentially creating a mini edible computer that requires an input, performs computation and results in different combinations of outputs while displaying different emoticons and flavours, allowing to the user to experience what computation ‘tastes’ like.”

A basic Logic Bonbon is filled with two flavours.

Co-author of the research, Exertions Games Lab Director Professor Florian ‘Floyd’ Mueller said the process of interacting with and understanding computation need not be restricted to linear methods.

“Through this project we are illustrating that even food materials and interacting with your meal can be a medium to introduce people to concepts of computer science,” Mueller said.

“It would be great to see this research applied and developed further by creators like chefs, food designers and gastronomists to introduce computational concepts in a fun multisensory way and deliver experiences where diners ‘execute’ the ‘software’ that the chef has programmed into their food.”

Possible future research building on this project will include developing more complex computational systems made of food to further explore how hospitality can be supported in delivering unique experiences to diners while supporting the chef’s craft and expertise.

The Logic Bonbon research findings will be presented during the ACM CHI Conference on Human Factors in Computing Systems being held in New Orleans, USA, from 30 April–5 May.
