# Introduction

<h2 align="center">Behavioral Imaging Toolbox: Bitbox</h2>

**Bitbox is the open-source Python library for computational analysis of nonverbal human behavior.** Bitbox  makes it easy to study facial expressions, head and body actions, eye gaze (coming soon), and speech behavior (coming soon) from videos and images.

{% endhint %}

Bitbox gives you all tools you need to study motor, social, emotional behavior.

* Psychomotor function: spatial extent, smoothness, speed, energy, temporal phases&#x20;
* Affective expression: expressive motion units, symmetry, expressivity, diversity, arousal
* Interpersonal dynamics: imitation, coordination, social gaze (coming soon), speech behavior (coming soon)

Bitbox can run on a laptop as a standalone processor, currently requiring an NVIDIA GPU. If more computational power is needed, Bitbox can also operate on a powerful server, providing a <mark style="color:purple;">`Python`</mark> client API. Additionally, Bitbox can be used on a high-performance computing cluster by submitting SLURM jobs (coming soon).
