标题: Cooperative Personal Projection Using Multiple DLP Projectors
Abstract

In this poster, we propose a novel interaction concept called “cooperative

personal projection”, which relies mainly on the Digital

Light Processing (DLP) color-wheel timing and short-exposure

cameras. This concept combines recently popular single-projector

personal-projection interactions with conventional multiprojector

cooperative interactions, enabling several users to share their personal

projections in a collaborative manner. By extending this proposed

concept to multiexposure cameras and pro–cam coaxialization,

we introduce a robust alternative for the real-time detection

and identification of the geometry of overlapping projections in

multiprojector scenarios that requires minimal computation.

1 Cooperative personal projection

Cooperative interaction and personal interaction, using projection

technologies, have been proposed independently. It is not straightforward

to combine multiple personal projections into one cooperative

system while maintaining complete personal control over the

projectors, particularly in vision-based systems. This is because the

projected images overlaid on the physical environment change the

visual appearance of the environment as seen by the camera. Subsequent

visual analysis of the environment may therefore be incorrect.

To solve this projection interference, we use an approach called

“nonin***sive projection” [Siriborvornratanakul and Sugimoto

2011]. In personal-projection scenarios using one pro–cam, only

one color segment of the DLP color wheel is used. However, in cooperative

personal projection using multiple pro–cams, we assign a

unique synchronization delay to each pro–cam to avoid the interference

at the overlapping projection areas. As a result, each camera

sees only the light from its paired projector while seeing no light

at all from other unpaired projectors. Synchronization among all

projectors is required for this approach, and our current implementation

uses wired technologies for this synchronization. Wireless

synchronization is a future goal, which will make the devices suitable

for mobile/portable usages.
