ProjectorBox

Presentation capture, indexing, and management

ProjectorBox is a smart appliance that automatically captures, indexes, and manages presentation multimedia.

It operates continuously to record the video information sent from presentation devices, such as a presenter’s laptop, to display devices, such as a projector.

It seamlessly captures high-resolution slide images, text and audio. It requires no operator, specialized software, or changes to current presentation practice. A web-based user interface allows users to search, replay, and export captured content. A web service API enables organizations to do more with the content that passes through their projectors and large displays.

Our research focuses on robust automatic media classification and segmentation, novel corporate memory and awareness applications, and real-time presentation enhancement services.

ProjectorBox has also been incorporated into our Corporate Memory system.

While researchers have been exploring automatic presentation capture since the 1990's, real world adoption has been limited. Our research focuses on simplifying presentation capture and retrieval to reduce adoption barriers. ProjectorBox is our attempt to create a smart appliance that seamlessly captures, indexes, and archives presentation media, with streamlined user interfaces for searching, skimming, and sharing content. In this paper we describe the design of ProjectorBox and compare its use across corporate and educational settings. While our evaluation confirms the usability and utility of our approach across settings, it also highlights differences in usage and user needs, suggesting enhancements for both markets. We describe new features we have implemented to address corporate needs for enhanced privacy and security, and new user interfaces for content discovery.

In a landmark article, over a half century ago, Vannevar Bush envisioned a "Memory Extender" device he dubbed the "memex". Bush's ideas anticipated and inspired numerous breakthroughs, including hypertext, the Internet, the World Wide Web, and Wikipedia. However, despite these triumphs, the memex has still not lived up to its potential in corporate settings. One reason is that corporate users often don't have sufficient time or incentives to contribute to a corporate memory or to explore others' contributions. At FXPAL, we are investigating ways to automatically create and retrieve useful corporate memories without any added burden on anyone. In this paper we discuss how ProjectorBox a smart appliance for automatic presentation capture and PAL Bar a system for proactively retrieving contextually relevant corporate memories have enabled us to integrate content from a variety of sources to create a cohesive multimedia corporate memory for our organization.

Technology abounds for capturing presentations. However, no simple solution exists that is completely automatic. ProjectorBox is a "zero user interaction" appliance that automatically captures, indexes, and manages presentation multimedia. It operates continuously to record the RGB information sent from presentation devices, such as a presenter's laptop, to display devices, such as a projector. It seamlessly captures high-resolution slide images, text and audio. It requires no operator, specialized software, or changes to current presentation practice. Automatic media analysis is used to detect presentation content and segment presentations. The analysis substantially enhances the web-based user interface for browsing, searching, and exporting captured presentations. ProjectorBox has been in use for over a year in our corporate conference room, and has been deployed in two universities. Our goal is to develop automatic capture services that address both corporate and educational needs.

Automatic lecture capture can help students, instructors, and educational institutions. Students can focus less on note-taking and more on what the instructor is saying. Instructors can provide access to lecture archives to help students study for exams and make-up missed classes. And online lecture recordings can be used to support distance learning. For these and other reasons, there has been great interest in automatically capturing classroom presentations. However, there is no simple solution that is completely automatic. ProjectorBox is our attempt to create a "zero user interaction" appliance that automatically captures, indexes, and manages presentation multimedia. It operates continuously to record the RGB information sent from presentation devices, such as an instructor's laptop, to display devices such as a projector. It seamlessly captures high-resolution slide images, text, and audio. A web-based user interface allows students to browse, search, replay, and export captured presentations.
