Electric, thermal, and magnetic based digital interfaces for next generation food experiences

In this article we present how electrical, magnetic, and thermal interfaces can create and modify taste and smell sensations with new interactions. In future, these technologies can play a vital role in food consumption, food manufacturing, food based interactions and multisensory communication. We provide a detail review of previous electrical, thermal and magnetic interfaces in the related research area and then we present the currently ongoing research works carried out by the authors. We also discuss how these technologies can create, modify new interactions for industry of foods, marketing, communication and computing. Especially we believe that the future of internet will not only depend with visual, audio, and tactile stimuli but also with smell (olfaction) and taste (gustation). Humans would share these stimuli collectively as an experience digitally, like they do with the visual and audio media on the internet. We want to propose an idea of digital olfaction and gustation as input and output for interaction for creating and experiencing digital representation of foods.
