Imagine cruising on a motorcycle at 160 kilometers per hour, with an arrow hovering in your line of sight, guiding you to your next turn--all without the need for a phone or dashboard. This futuristic scenario is set to become a reality on European roads as early as this year, showcasing the exciting trajectory of smart glasses technology.
In recent years, major tech companies have been making significant investments in this field. Meta has launched AI-enabled Ray-Ban glasses, Google is developing Android XR, and Apple is anticipated to join the market soon. Additionally, Samsung is reportedly preparing to unveil its first AI-capable smart glasses in collaboration with Gentle Monster at an upcoming Galaxy Unpacked event. Meanwhile, Chinese firms like Huawei, Alibaba, and Xiaomi are also advancing their own smart glasses initiatives.
The demand for AI glasses is evident, with global shipments expected to soar from 8.7 million units in 2025 to over 15 million this year, according to Omdia.
Among the innovators in this space is South Korea's LetinAR, a startup dedicated to creating the optical technology essential for making smart glasses practical and wearable. Backed by LG Electronics, LetinAR recently secured $18.5 million in funding from the Korea Development Bank and Lotte Ventures, as it gears up for a planned IPO in 2027.
Founded in 2016 by high school friends CEO Jaehyeok Kim and CTO Jeonghun Ha, LetinAR specializes in developing the optical modules that enable smart glasses to function effectively. The company's technology, known as PinTILT, arranges tiny optical elements within a lens to direct light precisely to the user's eye, enhancing image quality while keeping the glasses lightweight and power-efficient.
Kim emphasizes the importance of this optical module, stating, "We see AI glasses as that next platform," highlighting the need for advancements in lens technology that are thinner and more efficient than current models.
LetinAR's technology aims to overcome the limitations of existing lens designs, which often compromise image clarity and battery life. By focusing on delivering light directly to the eye, the PinTILT approach promises brighter images in a slimmer profile, addressing a key challenge in the industry.
The company has already begun shipping its modules to clients, including Japan's NTT QONOQ Devices and Dynabook. One of its notable projects is with Aegis Rider, a Swiss startup developing an AI-powered AR helmet that projects navigation and safety information directly onto the motorcycle rider's field of vision.
With its recent funding, LetinAR is poised to expand its operations as the market for AI glasses transitions from early adopters to mass production. Kim believes that hardware innovations like AI glasses will play a crucial role in integrating AI into daily life.
