Holographic Telepresence Robot HoloPresence Deep Dive: Making Distant People Appear Before You as Light

Video conferencing solved the efficiency problem of remote communication but has never been able to replicate presence. The person on screen is two-dimensional, lacks eye contact, and cannot interact with the physical environment. HoloPresence, jointly developed by Professor Hiroshi Ishiguro's Intelligent Robotics Laboratory at Osaka University and SoftBank Robotics, attempts to bridge this gap with a hybrid approach.

HoloPresence consists of two parts: a 1.7-meter humanoid robot base and a 360-degree holographic projection array installed on the base's head and torso. Remote participants wear VR headsets and motion capture suits, with their facial expressions, gestures, and body postures captured in real time and transmitted to the HoloPresence robot. The robot's head and upper body synchronize with the remote participant's movements, while the holographic projection array projects life-size 3D images on its surface.

Professor Ishiguro stated: "Pure holographic projection cannot interact with the physical world. You cannot shake hands with a hologram. But a robot with physical form can open doors, hand over documents, and even sign papers. HoloPresence is not positioned to replace video conferencing but to provide an option for scenarios requiring genuine presence."

The holographic projection array comprises 128 micro laser projectors covering 32 surface areas of the robot's head and upper body. Each projector updates at 120 frames per second, exploiting the human eye's persistence of vision to achieve seamless 3D imagery. The system requires 50 Mbps upload and 100 Mbps download bandwidth, with end-to-end latency controlled within 80 milliseconds.

SoftBank Robotics plans to position HoloPresence as an enterprise service at approximately 15,000 dollars per month, including equipment maintenance and network support. First target clients are multinational tech companies and medical institutions. Ishiguro's team is collaborating with the University of Tokyo Hospital to explore HoloPresence's application in remote surgical guidance.

Ishiguro has long studied human psychological responses to humanoid robots. He acknowledges that HoloPresence may trigger the uncanny valley effect. The team mitigates this by preserving subtle digital aesthetic elements in the imagery, ensuring users clearly perceive this as a remote presence rather than a real person.

"Our goal is not to trick the brain into believing a real person stands before you, but to provide sufficient presence to build genuine human connections," Ishiguro said.
