Opportunities and Challenges for Using Automatic Human Affect Analysis in Consumer Research

Abstract: The ability to automatically assess emotional responses via contact-free video recording taps into a rapidly growing market aimed at predicting consumer choices. If consumer attention and engagement are measurable in a reliable and accessible manner, relevant marketing decisions could be informed by objective data. Although significant advances have been made in automatic affect recognition, several practical and theoretical issues remain largely unresolved. These concern the lack of cross-system validation, a… Show more

“…In the wake of rapid advances in computer vision and machine learning, competing computational approaches now exist that focus on the analysis of facial expressions. Automatic facial affect recognition has significant advantages in terms of time and labor costs over human coding [22] and has been envisioned to give rise to numerous applications in fields as diverse as security, medicine, education, telecommunication, automotive, and marketing industries [23,24]. While the computational modelling of emotional expressions forms a narrow, although increasingly common, approach, the ultimate aim is to build human-computer interfaces that not only detect but also respond to emotional signals of the user [25,26].…”

“…Given the various methods employed for eliciting and validating dynamic facial expressions, the quantity and quality of data available on emotion recognition performance is a major issue (Küster et al, 2020 ). There is currently no normative standard that incorporates the diversity of approaches seen in the literature.…”

“…This process works well for larger samples; thus, spontaneous facial expressions were ideal for our study of 160 participants. Spontaneous expressions can also provide a benchmark for comparisons between different algorithms (Küster et al, 2020). We relied on a minimum of 90% of accurate facial analysis through all FaceReader analyses detected for each participant: each participant has been exposed to the website for a total of 3 min, and his/her facial expressions have been recorded for a total of 180 s. Only recordings that FaceReader processed properly for at least 162 s were considered.…”
