There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
---------------------------------
Visualization is a powerful tool for human-data interaction, enabling people to better understand their data, identify patterns, and discover insights. Correspondingly, there exist numerous systems that let people create and interact with visualizations to explore their data. Traditionally, interaction in these systems is facilitated through direct manipulation and control panels composing of common user interface widgets such as dropdown menus and sliders. However, recent advances in hardware and interpretation technologies present the opportunity to explore new visualization tools grounded in naturalistic human ways of interacting with other people and objects in the real world. Augmenting interaction techniques in current systems with natural language, this thesis explores the design of multimodal interfaces for data analysis with visualizations.
Specifically, I describe the design and implementation of a series of multimodal visualization systems that combine natural language and direct manipulation interaction. Furthermore, based on evaluations of these systems, I highlight the usage and utility of multimodal input for different visualization types (e.g., networks, unit visualizations) and devices (e.g., laptops, large touchscreens). By examining multimodal visualization systems in diverse contexts, this work demonstrates how multimodal interaction can promote the design of new visualization tools and support enhanced human-data interaction experiences during both individual and collaborative analysis.
