Dual Beaming Display for Extended Head Orientation and Projection Volume

Existing near-eye displays (NEDs) come with various tradeoffs, including size, weight, and battery life. The new "beaming display" model attempts to address these by splitting the NED into a steering projector (SP) and a passive headset. However, it has limitations in terms of projection a...

Description
Summary:Existing near-eye displays (NEDs) come with various tradeoffs, including size, weight, and battery life. The new "beaming display" model attempts to address these by splitting the NED into a steering projector (SP) and a passive headset. However, it has limitations in terms of projection area and user head movement. In this research, we utilize two steering projectors to expand the beaming display's capabilities. We introduce a geometric model and a control method specifically for multiple projectors. Tests indicate an accuracy of 3-19mm and a delay of 14.46 ms from a 1m distance to the SPs, allowing projection onto a 20mm x 30mm area of the headset. This method not only expands head movement possibilities but also shows potential for multiple users and improved dynamic range and binocular presentation.
