How to increase store dwell time and purchase rates with facial recognition AI stations

About

ROUNZ, South Korea’s leading eyewear franchise, is beloved for its diverse products and reasonable pricing. However, they faced a challenge: customers often felt pressured by the constant gaze of opticians, leading them to leave the store before fully exploring the collection. For international tourists, language barriers further diminished the quality of the shopping experience.

To address this, ROUNZ introduced Perso Interactive AI, creating a low-pressure, self-guided shopping environment powered by an AI Station and AI Avatar experience. Customers can now try on glasses virtually through facial recognition–based smart fitting, while returning visitors benefit from personalized recommendations based on purchase history. With Multilingual AI support, international customers can enjoy the same level of service without language barriers.

As a result, customers spent more time exploring products at their own pace—leading to measurable improvements in both in-store dwell time and conversion rates.

Background

Traditional eyewear retail relies heavily on direct assistance from opticians, which can inadvertently create a "high-pressure" environment for shoppers. ROUNZ envisioned a "low-pressure" space where customers could compare products freely, but they needed an intelligent digital partner to realize this vision. Additionally, the lack of multilingual capabilities was a significant hurdle in attracting global customers.

To overcome these challenges, ROUNZ sought to implement a solution that would allow customers to explore products independently while delivering a consistent, high-quality experience to both domestic and international visitors.

Solution

Powered by Perso Interactive AI, the in-store AI Station acts as an AI Avatar concierge, enhancing the shopping experience while supporting the role of opticians.

Using facial recognition technology, the system analyzes each customer’s face shape and recommends eyewear that best suits their features. For returning customers, it identifies previous purchase history to deliver a continuous, personalized shopping journey. When customers try on products, the system integrates with barcode scanning to instantly provide key information such as price, lens options, and available promotions.

Moreover, the Interactive system features intelligent language detection—automatically switching between Korean and English—allowing international guests to find exactly what they need without staff help. This frees opticians from repetitive inquiries, allowing them to focus on high-value professional tasks like fitting and prescriptions.

Results

Since the implementation of the service, the AI has naturally supported the customer exploration process, leading to a boost in overall conversion rates. Specifically, purchase rates among international customers—who previously hesitated due to language barriers—have seen a marked increase, strengthening the brand's global responsiveness.

The "low-pressure" shopping environment has naturally extended the time customers spend in the store. With real-time Multilingual support, ROUNZ now provides equal service quality to all global visitors.

Additionally, by reducing repetitive tasks, opticians were able to focus on specialized services, increasing the number of customers each staff member could handle and improving overall store efficiency.

Ultimately, the combination of facial recognition–based recommendations and data-driven personalization helped customers make more confident decisions—leading to higher satisfaction and improved business performance.
