In this paper, we explore the practice of using a whiteboard for multiple tasks, and specifically how users employ whiteboards to smoothly transition between related sets of tasks. Our study underscores several basic, but important affordances of whiteboards that support this practice, including visual persistence, flexibility of interaction primitives, and(More)
TeleAdvisor is a novel solution designed to support remote assistance tasks in many real-world scenarios. It consists of a video camera and a small projector mounted at the end of a tele-operated robotic arm. This enables a remote helper to view and interact with the workers' workspace, while controlling the point of view. It also provides the worker with a(More)
Large classrooms have traditionally provided multiple blackboards on which an entire lecture could be visible. In recent decades, classrooms were augmented with a data projector and screen, allowing computer-generated slides to replace hand-written blackboard presentations and overhead transparencies as the medium of choice. Many lecture halls and(More)
We introduce MultiPresenter, a novel presentation system designed to work on very large display spaces (multiple displays or physically large high-resolution displays). MultiPresenter allows presenters to organize and present pre-made and dynamic presentations that take advantage of a very large display space accessed from a personal laptop. Presenters can(More)
Museums are both appealing and challenging as an environment for indoor positioning research. By nature, they are dense and rich in objects and information, and as a result they contain more information than a visitor can absorb in a time-limited visit. Many research projects have explored the potential of novel technologies to support information delivery(More)
Large datasets of 3D objects require an intuitive way to browse and quickly explore shapes from the collection. We present a dynamic map of shapes where similar shapes are placed next to each other. Similarity between 3D models exists in a high dimensional space which cannot be accurately expressed in a two dimensional map. We solve this discrepancy by(More)
In this paper we describe the in-progress work of the Pathlight navigation system for groups and individuals. Pathlight provides indoor navigation support in the museum using a handheld projector. We describe some of the advantages the system provides, look at some background, briefly describe some system features, and posit some open questions for further(More)
Image fusion has gained importance with the advances in multispectral imaging. We examine four different fusion methods by comparing human observers' target detection performance with the resultant fused images. Three experiments with 89 participants were conducted. In the first experiment, images with multiple targets were presented to the participants.(More)
In this paper we investigate user performance and user behavior, related to the issue of who controls the point of view in a remote assistance scenario. We describe an experiment that examined users completing two different tasks with the aid of a remote gesturing device under two conditions: when control of the camera and gesturing point of view was in the(More)
