NoveltySeeking

Explore whether you are a novelty seeker with us.

Come to us and through advanced techniques we can determine whether or not you are a Novelty Seeker. You can contact us and we will arrange a series of tests for that.

This code is the app in the second step:

Watch a short movie
Complete the small videos part:
1. Put on the encephalograph.
2. Visit the webpage on Exploring The Brain (When you go to the webpage the encephalograph will be start recording automatically)
3. Watch some videos and answer a question based on each video you watched.
4. Complete the questionaire that comes after the video in the same webpage.
Drawing: You will draw a small image that will be acessed by some tachers at the arts department of our university.

This experiment was advised by professor Konstantinos Tsamis in the Medical school of the University of Ioannina.

Equipment that you will need

While this is a website that can be hosted on a simple web server, it uses the webserial api to contact the Arduino(described later) and use the encephalograph automatically. Unfortunately not all browsers support this api. Which means that you will have to use a suitable browser.(Google Chrome for example supports it).

Coding

Translations

The website supports translations in different languages. In order for you to create a tranlation in a different language you will have to:

Create a translation

go in the novelty-seeking/src/locales folder.
Duplicate any folder you know the language(source language) and rename it to the language you will translate it into(target language).
Go in the folder and you will find 3 json files. You will have to translate all of them without changing the names

Use a translationss

In order for you to use a translation in the webpage you will have to copy a little bit of code and change it.

Go to the src folder and open the index.js file.
Find the comment that refers to the template. It should have this:

 import translationEL from './locales/el/translation.json';
 import questionsEl from './locales/el/questions.json';
 import questionnaireEl from './locales/el/questionnaire.json';


 translationEL["quiz"] = questionsEl;
 translationEL["jtci-questions"] = questionnaireEl;

 i18n.init({
     interpolation: {escapeValue: false}, // React already does escaping
     lng: 'el', // Default language
     resources: {
         el: {
             common: translationEL,
         }
     },
 }).then(r => {
     console.log("i18n initialized");
 });

You will add your code like this:

 import translationEL from './locales/el/translation.json';
 import questionsEl from './locales/el/questions.json';
 import questionnaireEl from './locales/el/questionnaire.json';
 /**
  * Change this to your actual files and add the actual language code
  */
 import translationLang from './locales/lang/translation.json';
 import questionsLang from './locales/lang/questions.json';
 import questionnaireLang from './locales/lang/questionnaire.json';


 translationEL["quiz"] = questionsEl;
 translationEL["jtci-questions"] = questionnaireEl;


 /**
  * Change this to the actual language code
  * DO NOT CHANGE THE KEYS. They are used in the code and if you do it you will mess the website up
  */
 translationLang["quiz"] = questionsLang;
 translationLang["jtci-questions"] = questionnaireLang;

 /*
  * Add the language here(Change with the language code)
  */

 i18n.init({
     interpolation: {escapeValue: false}, // React already does escaping
     lng: 'el', // Default language
     resources: {
         el: {
             common: translationEL,
         },
 	lang: {
             common: translationLang,
         }
     },
 }).then(r => {
     console.log("i18n initialized");
 });

functionality for visual translation between the languages will be added soon.

Functionality

Folder structure:
-----------------
novelty-seeking: react app that shows the website, plus some php scripts in the public folder to store the data to the backend
ProcessResults: process the data from the database (You need to run it to the same server with the database as it connects to it)
encephalograph: folder that coontains the arduino project to connect t the encephalograph from the website

The app stores the data in a mysql database. You can initialize a database of your own by editing the .env file in the novelty-seeking folder and making sure that all are there

DB_HOST=localhost
DB_DATABASE=db
DB_USERNAME=user
DB_PASSWORD=passwd
REACT_APP_VALID_TOKEN="Something to prevent spam to your form"

You need to create the following tables in the database so that the data can be saved without errors:

CREATE TABLE `answer` (
  `code` int NOT NULL,
  `id` int NOT NULL,
  `choice` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_bin DEFAULT NULL,
  `category` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_bin DEFAULT NULL,
  `counter` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_bin DEFAULT NULL,
  `quiz` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_bin DEFAULT NULL,
  `date` int CHARACTER SET utf8mb3 COLLATE utf8mb3_bin DEFAULT NULL,
  `lang` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_bin DEFAULT NULL,
  PRIMARY KEY (`code`,`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3 COLLATE=utf8mb3_bin;


CREATE TABLE `questioner` (
  `code` int NOT NULL,
  `id` int NOT NULL,
  `answer` int NOT NULL,
  `lang` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_bin DEFAULT NULL,
  PRIMARY KEY (`code`,`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;


CREATE TABLE `user` (
  `code` int NOT NULL,
  `year_of_birth` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL,
  `sex` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL,
  PRIMARY KEY (`code`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

The website connects itself(using the webserial api) to an arduino that does the job of the start switch to the encephalograph. This means that you will need to compile and run on your arduino the arduino.ino file found in the encephalograph folder.
You will have to figure out where the pins that act as the switch in your encephalograph are. (You will have to use the pinout model for each encephalograph. It is not the same.) If it is 5V input, then you are good as it is.
1. you will need jumper cables to connect the arduino to the encephalograph
2. If you need 3.3V input, I have included a fritzin design that shows the schematics for a circuit that gets 5V as input and outputs 3.3V, so you will need the apropriate resistors and cables to create the circuit and connect it to the encephalograph
And please remember that you will need 2 USB ports for this to work. One for he arduino to control the encephalograph, and another for the encephalograph to send the data to the computer.
When you are done getting your data, you need to go to the ProcessResults/save_to_csv.py file and update the credentials to the database in the main function to the ones you used in th .env file.
If there is something wrong with the databse, you can run the restore_data.py file to fix it (but you will need to change the redentials in this script too)
