We have developed a technique, Aggregate Towers, that allows geospatial data to be visualized across a range of map scales. We use a combination of data aggregation algorithms and...
Time-series graphs are often used to visualize phenomena that change over time. Common tasks include comparing values at different points in time and searching for specified patte...
This work explores the use of ambient displays in the context of interruption. A multimodal interface was created to communicate with users by using two ambient channels for inter...
In this paper, we propose a fast and robust method for tracking a user’s hand and multiple fingertips; we then demonstrate gesture recognition based on measured fingertip traj...
We investigate methods of segmenting, visualizing, and indexing presentation videos by both audio and visual data. The audio track is segmented by speaker, and augmented with key ...
