The MindTrace toolbox functions as an interface between your experiment code and the webcam. After connecting to the toolbox from within your experiment, you can easily send commands to the toolbox in order to e.g. start recording via the webcam or take snapshots. Sending the appropriate commands for calibration points can also be easily communicated to the toolbox. Additionally, the toolbox ensures that all the data is stored in an appropriate format, so that it can be uploaded seamlessly into our system and analyzed immediately.
What do you need on your computer to make use of the MindTrace Toolbox?
First of all, you need Python 3 (up to version 3.6.5). Normally, Python comes pre-installed with all unix systems (Mac OS and Linux). However, you need to make sure that you are indeed using Python 3 (up to version 3.6.5). You can easily check your python version by pasting this line in your terminal:
If you are already running Python 3, there is no need to install it again. If you execute the commands below in a Mac or Linux environment, the installation command for Python 3 will be ignored, if Python 3 is already installed on your system.
