Video coding

This repository contains code to visualize Datavyu timelines from the PLAY project.

  • To (re)generate a set of timeline reports from data stored in analysis/csv/,
    • source("analysis/R/plot_timelines.R")
    • then lapply(c("NYU013", "NYU018", "NYU019", "NYU020"), plot_timelines, csv.dir = 'analysis/csv/')
    • This results in <sub.id>-timeline.{html,md} files which you can preview.
    • It also puts participant-specific plots in img/{NYU013,NYU018,NYU019,NYU020} respectively.
  • To generate a simple ioslides html-formatted slide deck, rmarkdown::render("PLAY-timelines.Rmd").
  • Or, just source("analysis/R/plot_all_timelines.R") which does all of this for you.

  • This file shows how to extract relevant segments from a PLAY project video that has already been coded.
