# e-Babylab

e-Babylab [(Lo et al., 2023)](https://link.springer.com/article/10.3758/s13428-023-02200-7) is an open source authoring tool that allows users or researchers to easily create, host, run, and manage online experiments, without writing a single line of code. Using this tool, experiments can be programmed to include any combinations of image, audio, and/or video contents as stimuli and record key presses, clicks, screen touches, audio, video, and eye gaze[^1]. Short-form versions of the MacArthur–Bates Communicative Development Inventories (CDIs; [Chai et al., 2020](https://doi.org/10.1044/2020_JSLHR-20-00361); [Mayor & Mani, 2019](https://doi.org/10.3758/s13428-018-1146-0)) can additionally be included in experiments, allowing users or researchers to collect CDI data online. 

[^1]: Online webcam eye-tracking is currently under beta testing. This feature is implemented based on WebGazer [(Papoutsaki et al., 2016)](https://jeffhuang.com/papers/WebGazer_IJCAI16.pdf) and allows self-calibration using participants' gaze to better suit e-Babylab's use with young children.
