What is it about?
In spite of the various approaches to altering eating behavior, we propose that an eating spoon can not only serve as a static food serving tool but can also play a more active role in human-food interaction. Specifically, we envision a new type of interactive possibility by introducing the shape-changing interface into the eating tool, where a shape-changing spoon can adapt its physical form dynamically and subtly to optimise the users’ eating behaviour without many cognitive and behavioural costs.

Why is it important?
Our empirical evidence indicated that SSpoon could achieve comparable effects to a small spoon (5ml) in reducing the eating rate by 13.7-16.1% and food consumption by 4.4-4.6% while retaining similar user satisfaction as a normal eating spoon (10ml). These results demonstrate the feasibility of a shape-changing eating utensil as a promising alternative to combat the growing concern of obesity.
Perspectives
I hope this paper could guide the future design of eating tools by extending the shape-changing concept to other dietary purposes that we want to encourage or discourage. Additionally, I hope this work benefits practitioners and researchers who are investigating user eating behaviour or redesigning the eating experience.
