Target selection is a fundamental aspect of interaction and is particularly challenging when targets are moving. We address this problem by introducing a novel selection technique we call Hold which temporarily pauses the content while selection is in progress to provide a static target. By studying users, we evaluate our method against two others for(More)
We propose to bring our novel rich media interface called <i>MediaDiver</i> demonstrating our new interaction techniques for viewing and annotating multiple view video. The demonstration allows attendees to experience novel moving target selection methods (called <i>Hold</i> and <i>Chase</i>), new multi-view selection techniques, automated quality of view(More)
We describe a new video interface based on a recorded personal navigation history which provides simple mechanisms to quickly find and watch previously viewed intervals, highlight segments of video the user found interesting and support other video tasks such as crowd-sourced video popularity measures and consumer-level video editing. Our novel history(More)
We present an investigation of two different visualizations of video history: Video Timeline and Video Tiles. Video Timeline extends the commonly employed list-based visualization for navigation history by applying size to indicate heuristics and occupying the full screen with a two-sided timeline. Video Tiles visualizes history items in a grid-based layout(More)
Figure 1: Our prototype history-based interface for casual video authoring. A history of personal video viewing provides a searchable set of intervals (left, red) which can be filtered to identify intervals viewed more than once (right, red). The video is linearly searchable using the filmstrip (blue). Any interval in the history can be added to the(More)
Figure 1: The View Count Record (VCR) visualization of a single video to highlight popular or unseen content using viewing statistics derived from personal or crowd-sourced histories of video consumption. The most-viewed intervals are represented by large thumbnails, with three smaller sizes to represent less-viewed content (the smallest for unseen(More)
The Video History System (VHS) manages a user's personal viewing history and provides mechanisms for quick navigation. Playback is controlled with familiar tools such as play/pause/seek, and previews are arranged as a filmstrip (left). As the user watches video, the VHS records each interval viewed. The history is then visualized in one of two ways: as(More)
The DreamThrower is a novel technology that explores virtually creating, throwing and catching dreams. It detects users' dream state by measuring rapid eye movement. Once the dream state is detected, sound and light stimuli is played to alter the dream. Users report on their dream, and they can send the stimuli that they have used to another person via an(More)
The DreamThrower is a novel technology that explores virtually creating , throwing and catching dreams. It detects users' dream state by measuring rapid eye movement (REM). Once the dream state is detected, sound and light stimuli is played to alter the dream. Users report on their dream, and they can send the stimuli that they have used to another person(More)
