Tools for working with data from word recognition eyetracking experiments.
Installation
First install the devtools package, then install the package from this repository.
install.packages("devtools")
devtools::install_github("tjmahr/littlelisteners")Background
This package was developed to support eyetracking word recognition experiments for the Little Listeners project. In these experiments, images are placed onscreen and followed by a spoken prompt to view one of the images. We record the participant’s gaze location over the course of a trial. By aggregating this gaze location over many trials, we can describe and measure a participant’s word recognition by showing how their gaze location changes in response to speech.
littlelisteners is my (Tristan Mahr’s) second or third attempt at making an eyetracking processing package in R. My design goals were to be generic (work on dataframes of eyetracking data) and not just bespoke outputs for individual eyetrackers and experiments. The package’s code tries to play well with the tidyverse as well.
