This is a double post for progress in our Infant Event Representations study at the Language and Cognitive Neuroscience Lab, at Teachers College.

We (1) created heatmaps that represent all participant gazepoints (2) and developed a specialized data visualization website for the Language and Cognition Lab at Columbia University. The LCN Video Comparison Tool helps us compare multiple experimental videos simultaneously with frame-by-frame precision.

The tool solves a common research problem: comparing participants’ responses side by side. Frame-precise synchronization reveals subtle behavioral patterns that would otherwise remain hidden in sequential viewing.

Capabilities:

  • Customizable grid layouts (1×1, 1×2, 2×2, 2×3)
  • Synchronized playback of multiple videos
  • Frame-by-frame navigation (1/30th of a second precision)
  • Leader video designation that others follow
  • Precise frame jumping/scrubbing across all videos

This project reflects my commitment to and interest in multiple means of data representation, aligning with Universal Design for Learning (UDL) principles in education.
