Welcome to the Interaction Geography Slicer! The IGS is an open-source tool to visualize movement, conversation, and video data over space and time. Data are displayed over a floor plan and a timeline in 2D and 3D views. Use the top menu to explore sample datasets or upload your own data. Interact with data by visualizing movement and conversation in different ways, animating and filtering data, watching video, and rescaling data with the interactive timeline. The IGS runs entirely in your browser. No transcripts or videos are uploaded, stored, or transmitted—your data stays on your device at all times.
IGS software is an open-source project licensed under the GNU General Public License Version 3.0. It is developed by Ben Rydal Shapiro, Edwin Zhao and contributors with support from the National Science Foundation #1623690 and #2100784. Example data is from the TIMSS 1999 Video Study and the Case of Sean Numbers from Mathematics Teaching and Learning to Teach (MTLT), University of Michigan (2010) used with special permission.
