E-commerce is undergoing a significant shift as companies move beyond traditional human hosts for live video sales. Digital characters, known as virtual streamers, are increasingly taking over the screen to showcase products and interact with shoppers. These computer-generated avatars operate around the clock and offer brands a way to control their messaging with absolute precision.
While the use of these digital entities is growing, questions remain regarding their effectiveness compared to humans. Businesses are investing heavily in this technology, yet the specific traits that make a virtual host successful are not fully understood. A recent investigation published in the journal Behavioral Sciences examines this exact issue.
The study investigates how the human-like qualities of these avatars influence a consumer’s willingness to spend money. The research specifically looks at the role of trust in this dynamic. It asks whether a realistic appearance is enough to drive sales or if consumers require deeper behavioral connections to feel comfortable making a purchase.
Identifying the Mechanism of Trust
Chunyu Li and Fei Huang, researchers associated with the Seoul Business School at aSSIST University, led this investigation. They identified a gap in current marketing literature regarding virtual streamers. While previous studies analyzed human influencers or static virtual characters, few have dissected the live streaming experience where real-time interaction occurs.
The researchers rooted their investigation in “avatar theory.” This concept suggests that the effectiveness of a digital character depends on how much it resembles a human in form and function. To understand this better, Li and Huang categorized “anthropomorphism”—the attribution of human traits to non-human entities—into four distinct dimensions.
The first dimension is appearance anthropomorphism, which refers to how visually realistic the character looks. The second is behavioral anthropomorphism, which involves how natural the character’s movements and interactions seem. The third, cognitive anthropomorphism, relates to the avatar’s perceived intelligence and logical reasoning. The final dimension is emotional anthropomorphism, or the character’s ability to express feelings and empathy.
A central concept in this study is “cognitive trust.” This is not a feeling based on warmth or friendship, but rather a rational judgment. It occurs when a consumer believes a streamer is competent, reliable, and professional. The researchers sought to trace the path from the avatar’s design features to the consumer’s cognitive trust, and finally to their intention to buy a product.
Surveying the Digital Consumer
To test their model, the research team designed a structured questionnaire targeting consumers in China. This market was selected due to its massive internet user base and the widespread adoption of live streaming e-commerce. The team focused specifically on individuals who had prior experience watching virtual streamers to ensure the data reflected genuine user experiences.
The data collection process was rigorous. The researchers distributed the survey online and included screening questions to disqualify anyone unfamiliar with the technology. Ultimately, they analyzed responses from 503 participants. The demographic profile of the respondents skewed young and educated, representing the core audience for digital commerce.
The researchers used a method called Structural Equation Modeling (SEM) to process the data. This statistical technique allowed them to test complex relationships between multiple variables simultaneously. They looked for patterns connecting the four types of anthropomorphism to the level of trust reported by users and their subsequent desire to purchase products.
The Role of Appearance in Sales
The analysis yielded unexpected results regarding the visual aspect of virtual streamers. The data showed that appearance anthropomorphism had a direct link to purchase intention. When an avatar looked more human and visually appealing, consumers were more likely to want to buy the featured products.
However, the analysis uncovered a limitation to visual realism. The study found that appearance anthropomorphism did not lead to an increase in cognitive trust. A realistic face or body did not convince viewers that the streamer was competent or reliable. The visual elements sparked a desire to buy, but they failed to build a foundation of rational trust.
This distinction highlights a critical separation in how consumers process digital images. They may enjoy the aesthetic of a highly realistic avatar, which prompts an immediate interest in the product. Yet, this visual fidelity does not help the consumer believe the information the avatar is providing is accurate or professional.
Building Trust Through Behavior and Logic
The results for behavioral and cognitive traits told a different story. The study showed that behavioral anthropomorphism—how naturally the avatar moves and interacts—was strongly linked to higher levels of cognitive trust. When the virtual streamer acted like a human, viewers perceived it as more reliable.
This increase in trust created a chain reaction. The analysis revealed that behavioral anthropomorphism did not directly increase purchase intention on its own. Instead, it triggered a process: the natural behavior increased the viewer’s trust, and that heightened trust subsequently increased the viewer’s willingness to buy.
A similar pattern emerged regarding cognitive anthropomorphism. When consumers perceived the avatar as intelligent and logical, their cognitive trust increased. This trust then served as a bridge to purchase intention. Without the establishment of trust, the avatar’s perceived intelligence did not independently drive sales.
The Power of Emotional Connection
The fourth dimension, emotional anthropomorphism, proved to be the most versatile factor in the study. The researchers found that when a virtual streamer displayed human-like emotions and empathy, it had a two-pronged effect. First, it directly boosted purchase intention, similar to the effect of physical appearance.
Simultaneously, emotional traits successfully built cognitive trust. The display of emotion made the avatar seem more credible and reliable to the audience. This established trust then led to a secondary increase in purchase intention.
This finding suggests that emotional capacity is a unique driver in the virtual space. It operates through both direct appeal and the indirect route of building credibility. Consumers appear to respond to emotional displays both viscerally, by wanting to buy, and rationally, by trusting the source.
The Necessity of Trust in Commerce
The study confirmed the central role of cognitive trust in the digital marketplace. The analysis showed a clear, positive link between cognitive trust and purchase intention across the board. When consumers believed the streamer was professional and reliable, they were significantly more likely to plan a purchase.
The researchers described cognitive trust as a “mediator.” In this context, it acts as a filter or a gateway. For behavioral and cognitive traits to translate into sales, they must first pass through this gateway of trust. If the behavior does not build trust, it does not lead to a sale.
This contrasts with appearance, which bypasses the trust gateway entirely. The findings paint a complex picture of consumer psychology. Shoppers can be charmed by a look, but they need to be reassured by behavior and intelligence.
Implications for Business Strategy
These findings offer specific direction for companies developing virtual streaming technology. The research indicates that investing solely in hyper-realistic graphics may yield diminishing returns regarding customer relationships. While good looks drive immediate interest, they do not sustain the credibility needed for long-term reliability.
Brands looking to increase conversion rates should focus on the “mind” and “heart” of their virtual avatars. The data suggests that programming avatars to demonstrate logic, answer questions intelligently, and move naturally is essential for building confidence in the brand. These traits reassure the consumer that the entity selling the product is competent.
Furthermore, the study highlights the value of emotional design. Developers should prioritize algorithms that allow avatars to express empathy and appropriate emotional reactions. This feature appears to offer the highest return, as it drives sales directly while simultaneously fortifying the brand’s reputation for reliability.
Unanswered Questions and Future Inquiry
The study opens several new avenues for investigation. The current research focused exclusively on Chinese consumers, who have a high exposure to live streaming commerce. It remains to be seen if these findings hold true in Western markets or other cultural contexts where skepticism of digital avatars might be higher.
Additionally, the researchers suggest future work could explore different types of trust. This study focused on cognitive (rational) trust, but affective (emotional) trust might play a different role. Understanding how these two forms of trust interact could provide a deeper understanding of the human-computer relationship.
Finally, the study relied on survey data where participants reported their feelings. Future research might benefit from analyzing real-time data from actual live streams. Observing how consumers react in the moment to specific avatar behaviors could validate these findings and refine the design principles for the next generation of virtual sales hosts.
