The Escritoire: A Personal Projected Display
نویسندگان
چکیده
The Escritoire is a horizontal desk surface that uses two overlapping digital projectors to create a foveal display – a large interactive surface that has a high-resolution area to accommodate the user’s focus of attention. In contrast to high cost, multi-projector display walls for group presentations or scientific visualization, it is an augmentation of the personal computer, designed for common tasks such as document viewing and annotation. The system is calibrated using planar homographies, and then warps the projected images in real time to compensate for the unconstrained positions of the projectors. To allow documents to be shared by multiple clients, the software is divided into a hardware-specific client driving the display, and a platform-independent server controlling the desk contents.

Escritoire: A Personal Projected Display
T he face of personal computing with its desktop metaphor has remained largely unchanged since the release of the Xerox Star in 1979. We created a system called the Escritoire to explore the issues in making and using a display that is much more like a real desk—the every day workspace that people use. Our system differs from the conventional interface in a number of ways: it provides much more...
متن کاملThe Escritoire: A personal projected display for interacting with documents
The Escritoire is a horizontal desk interface that uses two projectors to create a foveal display. Items such as images, documents, and the interactive displays of other conventional computers, can be manipulated on the desk using pens in both hands. The periphery covers the desk, providing ample space for laying out the objects relevant to a task, allowing them to be identified at a glance and...
متن کاملPersonal projected displays
Since the inception of the personal computer, the interface presented to users has been defined by the monitor screen, keyboard, and mouse, and by the framework of the desktop metaphor. It is very different from a physical desktop which has a large horizontal surface, allows paper documents to be arranged, browsed, and annotated, and is controlled via continuous movements with both hands. The d...
متن کاملExperiences Implementing and Using Personal Projected Displays
We have created a personal projected display called the Escritoire. Two projectors overlap to create a horizontal desk display, and two pens allow two-handed input. We describe the issues we encountered implementing this system and the results of experiments with single users working on their own and with pairs of users collaborating using separate desks. Cheap portable projectors form a displa...
متن کاملRemote collaboration on desk-sized displays
Work on remote collaboration has often focused on the person space created by a conventional videoconference where the participants see each other’s faces, but we argue that a task space containing shared visual information is more important for most tasks. Trends in display technology mean that large visual task spaces can be created to maximize the shared context between collaborators. We hav...
