This repository hosts the programs for additional experiments and sensor plugins for ExpEYES.

Installation

1. Install ExpEYES

You can install ExpEYES easily on any Linux machine. There are deb files available that we included in the repository. Please find details how to install ExpEYES in the Readme.md.

2. Steps to install experiments

The software extension that are available in this repository in the folder /experiments can be installed as follows:

• Copy the programs in home folder

  ####ToDo : Create makefile for installing programs in ExpEYEs directory and make these experiments available in a dropdown menu of main GUI.

3. How to run experiments

For Experiments various sensors and experimental setups are required. Typical steps are:

• Connect ExpEYES to your PC/Laptop
• Run Expeyes from Education Menue. The main ExpEYES GUI will popup. Check whether the device is detected.
• Then close the ExpEYES GUI.
• Open the terminal and run the program for e.g.

~ $ python coupledpendulum.py

4. How to collect and save data

In order to make the experiments useful you need to collect and save data.

• Please describe here how to collect data and to save and use it (TO DO)
