Abstract

There is growing interest in the development of new technologies that capitalize on our emerging understanding of the multisensory influences on flavor perception in order to enhance human–food interaction design. This review focuses on the role of (extrinsic) visual, auditory, and haptic/tactile elements in modulating flavor perception and more generally, our food and drink experiences. We review some of the most exciting examples of recent multisensory technologies for augmenting such experiences. Here, we discuss applications for these technologies, for example, in the field of food experience design, in the support of healthy eating, and in the rapidly growing world of sensory marketing. However, as the review makes clear, while there are many opportunities for novel human–food interaction design, there are also a number of challenges that will need to be tackled before new technologies can be meaningfully integrated into our everyday food and drink experiences.

Highlights

  • Interest in multisensory perception is growing rapidly in the fields of Human–Computer Interaction (HCI, Obrist et al, 2016), sensory marketing (e.g., Petit et al, 2015), and the arts (e.g., Haverkamp, 2013; Vi et al, 2017)

  • Multisensory technologies, that is, technologies that are designed to stimulate the human senses, allow researchers to control the different inputs that accompany a given multisensory flavor, or food experience. It can be asked, use multisensory technologies in order to augment our flavor experiences? Given that technology is already ubiquitous in our everyday experiences, such technologies in the context of HFI hold the potential to transform how we will eat in the future (Spence and PiquerasFiszman, 2013)

  • Flavor Augmentation science and technology in systems capable of augmenting flavor perception can impact what people choose to eat and drink, how they perceive the ensuing flavor experience, and how much they end-up consuming. In this mini-review, we present an overview of multisensory technologies for flavor augmentation that have been developed recently

INTRODUCTION

Interest in multisensory perception is growing rapidly in the fields of Human–Computer Interaction (HCI, Obrist et al, 2016), sensory marketing (e.g., Petit et al, 2015), and the arts (e.g., Haverkamp, 2013; Vi et al, 2017). Multisensory technologies, that is, technologies that are designed to stimulate the human senses, allow researchers to control the different inputs that accompany a given multisensory flavor, or food experience. Flavor Augmentation science (e.g., considering the guiding principles of multisensory flavor perception, e.g., Prescott, 2015; Spence, 2015a) and technology in systems capable of augmenting flavor perception can impact what people choose to eat and drink, how they perceive the ensuing flavor experience, and how much they end-up consuming. In this mini-review, we present an overview of multisensory technologies for flavor augmentation that have been developed recently. We conclude by presenting challenges that face those wanting to augment flavor perception and experiences
