Projector phones are starting to be marketed for business presentations and media viewing, and we have begun to document how people use them "in the wild." We have observed that, in addition to the expected uses, projector phones afford novel interaction modalities. A key observation is that users can readily exploit projector phones' new facilities to author effects employing superimposition, ...

TYLER M. JOHNSON: A Cooperative Approach to Continuous Calibration in Multi-Projector Displays (Under the direction of Henry Fuchs) Projection-based displays are often used to create large, immersive environments for virtual reality (VR), simulation, and training. These displays have become increasingly widespread due to the decreasing cost of projectors and advances in calibration and renderin...

Abstract Pathology telemedicine uses digital data of pathological samples to acquire technical support from sophisticated remote experts, aiding cancer diagnosis in less developed regions. In this paper, we propose a color 3D observation system composed three cameras and projector, achieving complete range imaging pathology tissues. A new phase mapping method for the projector calibration is pr...

Standard presentation systems consisting of a laptop connected to a projector suffer from two problems: (1) the projected image appears distorted (keystoned) unless the projector is precisely aligned to the projection screen; (2) the speaker is forced to interact with the computer rather than the audience. This paper shows how the addition of an uncalibrated camera, aimed at the screen, solves ...

In this technical report, we present a detailed overview of PixelFlex, a multi-projector display system that combines multiple roughly aligned projectors into a unified highresolution display. We describe the current prototype, the automated calibration process, and two rendering algorithms that support interactive applications. The first rendering algorithm is a one-pass technique that assumes...

A complex square matrix A is said to be idempotent, or a projector, whenever A2 = A; when A is idempotent, and Hermitian (or real symmetric), it is often called an orthogonal projector, otherwise an oblique projector. Projectors are closely linked to generalized inverses of matrices. For example, for a given matrix A the product PA = AA + is well known as the orthogonal projector on the range (...

Some of the important technical characteristics of photogrammetric system are the speed of 3D acquisition, automation and possibility for smart operating. Using structured and coded light allows to solve correspondence problem fast, robustly and accurate. And applying of PC-controlled structured light provides a possibility to make a step to highly automated and intellectual photogrammetric sys...

This paper describes the current design characteristics and performance capabilities of the US Army Missile Command's (USAMICOM's) diode laser based infrared scene projector technology. The projector is now operational at the US Army Missile Command's Research, Development, and Engineering Center (RDEC) and is being integrated into several HWIL simulation facilities. The projector is based upon...

I propose a scheme for reconstructing the weak value of an observable without the need for weak measurements. The post-selection in weak measurements is replaced by an initial projector measurement. The observable can be measured using any form of interaction, including projective measurements. The reconstruction is effected by measuring the change in the expectation value of the observable due...
