Obesity and other lifestyle-related diseases are, amongst others, the result of an unbalanced diet and lifestyle. Excessive intake of energy, salt, saturated fat and sugar are leading to increased risk of chronic diseases, such as cardiovascular diseases, cancer and diabetes (WHO/FAO). Therefore, a healthier food intake (diet) is needed. But when is a food product healthier? From a nutritional perspective it is clear: the lower the levels of nutrients with a negative public health impact, the better the product fits in a healthy diet. However, when it comes to improving the health impact of the food supply through reformulation, other aspects are important as well. This article describes the ‘framework for product reformulation’, which integrates four essential disciplines: Nutrition & health, Foodtechnology, Legislation and Consumer perspective.

This paper introduces a design case that was built around the challenge to design a prototype for women that would positively influence their perception of personal safety in public spaces. The proposed design combines an individual focus with a public impact, influencing emotions through embodiment by introducing a necklace that reminds the wearer to walk straight and as a result, influence felt emotions such as confidence and prevent feelings of unsafety caused by slouching. In this paper, a prototype for wearable technology called PosturAroma is introduced: a fashionable necklace with a sensor that detects slouched body posture and reminds the user to stand straight by giving out a discrete scent.

Behaviour Change Support Systems (BCSS), already running for the 10th time at Persuasive Technology, is a workshop that builds around the concept of systems that are specifically designed to help and support behaviour change in individuals or groups. The highly multi-disciplinary nature of designing and implementing behaviour change strategies and systems for the strategies has been in the forefront of this workshop from the very beginning. The persuasive technology field is becoming a linking pin connecting natural and social sciences, requiring a holistic view on persuasive technologies, as well as multi-disciplinary approach for design, implementation, and evaluation. So far, the capacities of technologies to change behaviours and to continuously monitor the progress and effects of interventions are not being used to its full potential. The use of technologies as persuaders may shed a new light on the interaction process of persuasion, influencing attitudes and behaviours. Yet, although human- computer interaction is social in nature and people often do see computers as social actors, it is still unknown how these interactions re-shape attitude, beliefs, and emotions, or how they change behaviour, and what the drawbacks are for persuasion via technologies. Humans re-shape technology, changing their goals during usage. This means that persuasion is not a static ad hoc event but an ongoing process. Technology has the capacity to create smart (virtual) persuasive environments that provide simultaneously multimodal cues and psycho-physiological feedback for personal change by strengthening emotional, social, and physical presence. An array of persuasive applications has been developed over the past decade with an aim to induce desirable behaviour change. Persuasive applications have shown promising results in motivating and supporting people to change or adopt new behaviours and attitudes in various domains such as health and wellbeing, sustainable energy, education, and marketing. This workshop aims at connecting multidisciplinary researchers, practitioners and experts from a variety of scientific domains, such as information sciences, human-computer interaction, industrial design, psychology and medicine. This interactive workshop will act as a forum where experts from multiple disciplines can present their work, and can discuss and debate the pillars for persuasive technology.
