Why it matters: After the collapse of Smartisan and his exploration of e-commerce livestreams, Luo has quickly shifted his focus from AR to AI. Details: Thin Red Line was founded by Luo two years ago with an initial focus on AR technology; he has previously described the firm as his “last venture”. Additionally, several employees told ifeng.com that, similar to his approach in the Smartisan era, Luo’s high expectations and perfectionism have made product development particularly challenging. Moreover, efficient development of AR technology faces numerous hurdles, particularly in terms of breakthroughs in batteries, chips, and optics. He established Smartisan Technology in 2012 and released the Smartisan smartphone and operating system.
