Peripheral Notification That Does Not Interfere with User's Concentration by Interactive Projection

Nowadays, a variety of information is often delivered to a user by push notification. However, such notification often interferes with the user's concentration on his/her task, because it generally occurs without considering his/her convenience. The peripheral notification method notifies by displaying a message in the user's peripheral field of view. It depends on the degree of his/her concentration whether the user will notice the message or not. That is, the peripheral notification can reduce interference with the user's concentration on the task. However, the usual peripheral notification cannot be applied to the case that a user's head pose changes and his/her field of view can move. In this paper, in order to solve this problem, we propose a novel information notification system using the interactive projection system. It is expected that our proposed system reduces interference with a user's concentration even if his/her head pose changes and the VFN region moves during a task. Experimental results show the effectiveness of the proposed system.
