- Interaction styles. FOCUS PLUS CONTEXT (2008)

Mark Ashdown, Yoichi Sato

The use of multiple monitors is becoming popular but it creates problems for pointer movement, window management, and control of applications. We suggest combining the standard input devices of...

Designing Tabletop Interfaces for Asymmetric Distributed Collaboration (2008)

Mark Ashdown, Stacey D. Scott

Complex task domains such as emergency response and command and control often involve collaboration between operational personnel in the field and tactical personnel in a central command centre...

Applications for Multi-Planar Projected Displays (2008)

Mark Ashdown, Matthew Flagg, Rahul Sukthankar, James M. Rehg

Recent advances in commodity high-resolution ultraportable projectors have stimulated the development of a variety of novel projected displays [2]. The effort involved in manually aligning projected...

The Writing’s on the Wall: Large, Remotely Controlled Displays (2007)

Mark Ashdown, Peter Robinson

Large display devices are now affordable and desirable in fixed environments such as offices, and scalable methods are available to combine multiple projectors to form such displays with high...

Combining Head Tracking and Mouse Input for a Gui on Multiple Monitors (2005)

Mark Ashdown, Kenji Oka, Yoichi Sato

The use of multiple LCD monitors is becoming popular as prices are reduced, but this creates problems for window management and switching between applications. For a single monitor, eye tracking can...

Remote Collaboration on desk-sized displays (2005)

Mark Ashdown, Peter Robinson

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...

Intelligent tutoring and supervised problem solving in the browser (2004)

William Billingsley, Peter Robinson, Mark Ashdown, Chris Hanson

Web-based intelligent tutoring systems are becoming increasingly sophisticated. One approach to the resulting complexity is to separate the application into a front-end applet providing the user...

A flexible projector-camera system for multi-planar displays (2004)

A flexible projector-camera system for multi-planar displays (2004)

Mark Ashdown, Matthew Flagg, Rahul Sukthankar, James M. Rehg

We present a novel multi-planar display system based on an uncalibrated projector-camera pair. Our system exploits the juxtaposition of planar surfaces in a room to create ad-hoc visualization and...

Escritoire: A personal projected display (2003)

Mark Ashdown, Peter Robinson

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...

Escritoire: A personal projected display (2003)

Mark Ashdown, C Mark Ashdown, Peter Robinson, Peter Robinson

The 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,...

Robust calibration of camera-projector system for multi-planar displays (2003)

Mark Ashdown, Mark Ashdown, Rahul Sukthankar, Rahul Sukthankar

camera, projector, computer vision, homography We present a robust calibration method for aligning a camera-projector system to multiple planar surfaces. Unlike prior work, we do not recover the 3D...

Experiences implementing and using personal projected displays (2003)

Mark Ashdown, Peter Robinson

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...

A Life-Sized Desk Display for Peripheral Awareness and Remote Collaboration (2003)

Mark Ashdown, Peter Robinson

We present a horizontal life-sized desk display called the Escritoire. It fills a much larger visual angle than a conventional monitor, and thus exploits the user's peripheral vision. Two-handed...

Escritoire: A personal projected display (2003)

Mark Ashdown

User interfaces using windows, keyboard and mouse have been in use for over 30 years, but only offer limited facilities to the user. Conventional displays are small, at least compared with a physical...

All-sky convolution for polarimetry experiments (2000)

Challinor, Anthony, Fosalba, Pablo, Mortlock, Daniel, Ashdown, Mark, Wandelt, Benjamin, Gorski, Krzysztof

We discuss all-sky convolution of the instrument beam with the sky signal in polarimetry experiments, such as the Planck mission which will map the temperature anisotropy and polarization of the...
