PDH is a new digital content user interface and management system. Unlike conventional desktop user interfaces, PDH is intended for multi-user collaborative applications on single display groupware. PDH enables casual, interactive and exploratory retrieval, interaction with and visualization of digital contents. PDH is built with of our DiamondSpin Jave Tool Kit API. Our current project includes research in the areas of content annotation, retrieval and presentation, visualization of and user interaction with images, audio, video and data, as well as the study of how people collaboratively use the single display interface.
Background & Objective: As part of people's daily life at work, on the go and at home, their computers, PDAs and digital cameras generate larger and larger amounts of digital contents. However, technologies that allow people to easily utilize this digital data in a face-to-face conversational or group setting are lagging far behind. Applications are limited by the user interface potentials of current desktop computers and handheld devices. The objective of the PDH project is to take a step beyond.
Technical Discussion: Creating a new type of interface requires addressing many issues. One of our primary focuses is on developing content organization and retrieval methods that are easy and understandable for the users, and can be used without distracting them from their conversation. Rather than the folder & file mechanisms used by conventional document systems, PDH organizes the contents along the four W's of storytelling (Who, When, Where, and What) and allows users to design new contexts for organizing their structures. A second issue we have focused on is affording casual and exploratory interaction with data by combining a multiplicity of user interaction mechanisms including in-place query and in-place pop-up menus, direct manipulation, natural visual query formulation with minimal menu-driven interaction and freeform strokes. Finally, in order to support the multi-threaded and non-linear progression of group conversation, PDH provides tools to help people navigate a conversation as well as their content.
