1on1 Event 'Portal Meet' Using Portalgraph Featured on TV

On December 15, 2025, our COO Naoya Matsumoto appeared on Nagasaki Cable Media's live program "Nanden Cafe" in the "Vtuber PRESS+" segment. Alongside VTuber ChumuNote, Naoya introduced Portalgraph technology and discussed the "Portal Meet" event that took place last month.

During the program, Naoya explained how Portalgraph enables stereoscopic 3D content to be projected from any flat display—LED screens, TVs, projectors—creating the illusion that objects are emerging from the screen. He also introduced the real-time 1on1 system developed specifically for the event, which allows visitors to interact with VTubers in life-size 3D, including making eye contact, high-fiving, and having their heads patted. The system also enables taking life-size 3D "cheki" photos with VTubers.

ChumuNote, who participated in the event, shared their experience: "From a VTuber's perspective, being able to do events in 3D was very valuable. Events like these normally require equipment for 3D and showing movement is usually a large-scale operation, but Portalgraph makes it very convenient and easy to do. VTubers' back views are quite rare—being able to show that was great!"
