Feature of Users’ Eye Movements during a Distributed and Synchronised VR Meeting using Cloud Computing

Owing to cloud computing Virtual Reality (cloud-VR), a note PC or tablet with no need for a high spec GPU can be used for sharing a 3D virtual space in a synchronous distributed type design meeting. This research investigates the users’ eye movements and optimization of the GUI of cloud-VR during a distributed and synchronized VR meeting. Firstly, a townscape design support system based on cloud-VR was constructed. Then, a 30-minute experiment was executed with eight subjects who wore an eye-tracking system. In conclusion, it was effective to use the eye-tracking system because meeting participants could discuss while confirming each other’s eye direction in an actual distributed and synchronized VR meeting. In scenes where a reviewer listened to a presenter’s explanation, the tendency to look at VR contents other than operation commands was observed. On the other hand, the tendency to look at operation commands about viewpoints, such as “walk-through” and “jump” to an important viewpoint location, was observed in scenes about which a reviewer argued with a presenter
