ConAn

This is the official repository for ConAn: A Usable Tool for Multimodal Conversation Analysis
ConAn – our graphical tool for multimodal conversation analysis – takes 360 degree videos recorded during multiperson group interactions as input. ConAn integrates state-of-the-art models for gaze estimation, active speaker detection, facial action unit detection, and body movement detection and can output quantitative reports both at individual and group level, as well as different visualizations that provide qualitative insights into group interaction.

Installation

For the graphical user interface (GUI) you need python>3.6 to install the requirements via pip:

pip install requirements.txt 

Get Started

To test the GUI you can download our example use case videos from https://www.perceptualui.org/research/datasets/ConAn/
As well as the respective processed .dat files which include all the analyses.
You can then run main.py and import the video file you would like to analyze.

Processing

If you would like to analyze your own 360° video you can find the processing pipeline at processing/. Please note the processing pipeline requires a GPU.
