In this blog post, we’ll explore how emotional engineering influences product development and consumer purchasing behavior.
We live within “society.” Society refers to a community where people gather to exchange diverse ideas, sometimes clashing as they seek a better path forward. While discovering and pioneering new concepts was once considered the most important value, today the process of reexamining existing values and improving efficiency holds equal significance. Engineering plays a vital role amid these changes. While fields that drive technological advancement—such as mechanical and chemical engineering—have made significant strides, research focused on the people who actually use that technology—that is, ergonomics—has also established itself as a vital field. Although the term “engineering” often brings to mind large-scale industrial sites or specialized research, it is actually very closely intertwined with our daily lives.
From the design of workspaces to the analysis of human errors and various marketing techniques, the goal of ergonomics is to conduct engineering research aimed at ensuring people experience the greatest comfort and satisfaction. Ergonomics is also utilized in product development, design, and marketing processes to satisfy people’s needs and desires; a prime example of this is affective engineering. Emotional engineering is an approach that involves analyzing human emotions from an engineering perspective to predict and understand consumers’ emotional structures, thereby incorporating these insights into product development. Apple is a prime example of a company that has successfully utilized emotional engineering.
When the iPod first debuted, devices like the Walkman, along with MP3 players and portable media players (PMPs), dominated the music player market, and the line between cell phones and music players was relatively distinct. In this context, Apple actively utilized emotional engineering to differentiate its products. The core elements of emotional engineering generally include biomechanics, the humanities, and physiology, and Apple effectively applied these elements to its product development.
First, biomechanics is the field that studies human physical characteristics. It involves statistically analyzing physical traits—such as hand size and arm length—to determine which design will provide the highest level of satisfaction. Typical smartphones are designed to be comfortably used with one hand. However, the same product may feel relatively small to someone with very large hands. Thus, designing products based on an analysis of average physical characteristics is crucial. The iPod was also designed by comprehensively analyzing vast amounts of user data—including gender, age, and usage environments—to determine the appropriate size and shape, and the product was finalized through repeated user testing. This process serves as a prime example of how ergonomics and emotional engineering are applied in actual product development.
The second element, the humanities, enables the philosophy embedded in a product and facilitates communication with consumers. While engineering and philosophy may seem worlds apart, in reality, various engineering technologies are utilized to analyze consumer emotions and perceptions. One of the most representative methods is “crawling,” which involves analyzing internet data. Crawling is a technology that collects various information from the web and analyzes words and expressions to statistically gauge positive or negative reactions. Through this, companies can analyze consumer perceptions of their products and the image associated with specific products or brands. When Apple entered the highly competitive music player market, it focused on building a brand image that differentiated itself from existing MP3 players. As a result, it created the unique brand name “iPod” and, by continuously expanding its “i” series, instilled in consumers the image of a product that offers a new experience distinct from existing products.
Finally, physiology is the field that studies human physiological characteristics and physical responses and applies them to product development. The touch-based control interface of the iPod is a prime example of this. At the time, button-based controls were the norm, and touch technology was primarily limited to touchscreens. However, the iPod actively incorporated touch controls into its interface. Furthermore, to compensate for the lack of tactile feedback that touch controls might otherwise lack, it incorporated sound effects, directional cues, and haptic feedback, thereby maintaining the advantages of button-based controls while delivering a new user experience. Moreover, by analyzing how physiological characteristics—such as finger movements and sweat—affect touch controls and incorporating these insights into product development, usability was further enhanced.
In this way, affective engineering has moved beyond a mere trend to become a key element in product development. Today, it is widely utilized not only in product development but also in the design of various services and large-scale systems. Whereas performance and functionality were once the core of a product’s competitiveness, products that satisfy users’ emotions and experiences have now become even more important. Creating products where functionality, design, and user experience are in harmony has become a critical challenge in modern product development.
