A narrative review of the impact of digital immersive technology on affective and sensory responses during product testing in digital eating contexts

"That Looks Like My Kitchen!" - Personalized context by usage frequency and familiarity influences consumer perception and liking of chicken nuggets in VR

Restoring relevant context during consumer sensory testing using virtual reality (VR) technologies may facilitate evaluations reflective of real-world experiences, enabling reliable data collection to better predict product success. Prior research has applied the same consumption scenario to all participants without accounting for variations in individual consumption habits. Thus, a consumption scenario of low personal relevance can lead to misleading conclusions. This study aimed to investigate how personal relevance (usage frequency and similarity) of a consumption environment influences consumer perception and acceptance during product evaluations. Using a VR system, 63 consumers evaluated four commercial frozen chicken nuggets in three virtual environments one week apart: sensory booth, high-relevance kitchen, and low-relevance kitchen. Participants assessed the products virtually on overall liking, Check-All-That-Apply (CATA) on 20 attributes, and purchase intent. They also completed a virtual presence and engagement questionnaire after testing. Results found better product discrimination in both kitchen environments compared to the booth as demonstrated in more post-hoc statistical subgroups (p's < 0.05) on liking and purchase intent. Additionally, more significant product differences were found among CATA attributes in the kitchens. CATA penalty-lift analyses indicated that sensory attributes had more pronounced positive and negative impacts on liking in the high relevance kitchen, followed by the low relevance kitchen, and lastly the booth. Consumers were equally present and engaged during testing across conditions (p's > 0.05). Results suggest providing a personally relevant consumption environment via VR technologies for consumer testing generated more discriminating data that can improve the quality of consumer insights.

Immersive sensory evaluation: Practical use of virtual reality sensory booth

Sensory booths enhanced with VR technology have displayed promising potential for improving sensory evaluation, perception research, and educational experiences. However, there remains an insufficient of data on VR's utilization in sensory science. In our research, we designed a virtual sensory booth (SB) utilizing Virtual Reality (VR) to complement sensory analysis and foster applications in the field of sensory science. The experiment involved the utilization of diverse sensory methods and product samples for examination within the virtual SB, which was compared to the traditional SB. A total of forty-three participants took part in the study to scrutinize the implications of the virtual SB. The results of a post-VR questionnaire demonstrated the participants' positive reception of the virtual SB. The study's findings suggest that the virtual SB could serve as a valuable resource for sensory scientists and individuals keen on exploring the emerging opportunities offered by VR. Notably, the virtual SB has proven to have potential applications, particularly within the food industry, with a special focus on sensory science. •Virtualized SB incorporating VR technology is a promising sensory evaluation and perception studies approach.•Virtual SB intends to use various sensory methods in VR applications for sensory analysis.•The creation of new VR-based technological solutions for sensory analysis can serve as a supplement to traditional sensory analysis.

Virtual, augmented, and mixed reality as a versatile tool in food consumer behavior evaluation: Recent advances in aroma, taste, and texture incorporation

The perceptual behavior of consumers on a product displayed in the market has a vital role in analyzing the importance given to that product. Therefore, various strategies have been developed to understand this consumer behavior in the selection of products. Immersive technologies like virtual, augmented, and mixed reality are among them. With the foremost feature of immersion in the virtual world and interaction of users with virtual objects, virtual reality, and augmented reality have unlocked their potential in research and a user-friendly tool for analyzing consumer behavior. In addition to these technologies, mixed reality also has a significant role in investigating consumer behavior. Studies on immersive technologies in food applications are vast, hence this review focuses on the applications of virtual, augmented, and mixed reality in the food selection behavior of consumers. The behavioral studies are elicited to develop new products based on consumer needs, to understand the shopping behavior in supermarkets for real-time usage, and to know the influence of emotions in a selection of products. The findings suggest that virtual, augmented, and mixed reality induce immersion of the users in food selection behavioral studies. Information on the technological advancements in the tools used for bringing immersion and interaction are discussed for its futuristic applications in food. Though immersive technology gives users a realistic virtual environment experience, its application in food systems is in the budding stage. More research on human response studies would contribute to its innovative and inevitable application in the future.

Consumer Studies: Beyond Acceptability—A Case Study with Beer

Beer is one of the most consumed alcoholic beverages in the world; its consumption and preference are evolving from traditional industrial beers of low complexity to novel craft beers with diverse flavour profiles. In such a competitive industry and considering the complexity of consumer behaviour, improvement and innovation become necessary. Consequently, consumer science, which is responsible for identifying the motivation behind customer preferences through their attitudes, perception and behaviour, has implemented strategies ranging from simple hedonic measurements to several innovative and emerging methodologies for a deeper understanding of the variables that affect the product experience: sensory, affective and cognitive. In this context, we offer a review inspired by previous research that explores some of the quantitative and qualitative methods used in consumer studies related to beer consumption, ranging from traditional approaches (acceptability, purchase intention, preference, etc.) to techniques that go beyond acceptability and allow a different understanding of aspects of consumer perception and behaviour (segmentation, expectations, emotions, representation, etc.). Also, innovative applications (contexts, immersive technologies and virtual reality, implicit measures, etc.) and current trends related to consumer science (Internet, social media, pairing, product experience, etc.) are addressed.
