# JavaScript framework for the Emotiv EPOC [WIP]
This framework provides an interface to access data from the Emotiv EPOC brain sensor using Node.js.
To use this framework, you're gonna need an EPOC / EPOC+ or Insight that you can buy [here](https://emotiv.com/).
Originally based on the [epocutils library](http://stephaneag.github.io/epocutils/) by [@StephaneAG](https://github.com/stephaneAG)
## Demo:
## Status:
* **Refactored to use latest SDK (v3.5.0).**
* Cognitive actions should now be working.
## How to Install
* Download the **Emotiv Community SDK v3.4.0** [here](https://github.com/Emotiv/community-sdk/releases) and copy the `edk.framework` file (community-sdk > lib > Mac > edk.framework) to `/Library/Frameworks` (on Mac).
* Either clone this repo and run
```
npm install
```
or just run:
```
npm install epocjs
```
## How to Use
When writing a program, use either the `connectToEmoComposer` or `connectToLiveData` function to use the emulator or the data coming from the device.
Example of simple program:
```JavaScript
var Epoc = require('epocjs')();
Epoc.connectToLiveData("", function(event){
if(event.smile > 0){
console.log('smiling')
}
})
```
or:
```JavaScript
var Epoc = require('epocjs')();
Epoc.connectToEmoComposer(function(event){
if(event.smile > 0){
console.log('smiling')
}
})
```
The path to your user file should be something like this */Users/< username >/Library/Application Support/Emotiv/Profiles/< filename >.emu*
## Device data
---
Getting the battery level - only working when connecting to the device, not the EmoComposer.
This event should happen everytime the battery level changes.
```javascript
if(event.batteryLevel > 0){
//do something
}
```
---
## Events
---
#### Smile
If the value is superior to 0, the headset is detecting that the user is smiling.
```JavaScript
if(event.smile > 0){
// do something
}
```
---
#### Looking Up / Down / Left / Right
The headset can detect the direction in which the user is looking:
```JavaScript
if(event.lookingUp > 0){
// do something
}
if(event.lookingDown > 0){
// do something
}
if(event.lookingLeft > 0){
// do something
}
if(event.lookingRight > 0){
// do something
}
```
---
#### Blink
Detect if the user blinked:
```JavaScript
if(event.blink > 0){
// do something
}
```
---
#### Winking Left / Right
The headset can detect if the user is winking:
```JavaScript
if(event.winkingLeft > 0){
// do something
}
if(event.winkingRight > 0){
// do something
}
```
---
#### Laugh
Detect if the user is laughing:
```JavaScript
if(event.laugh > 0){
// do something
}
```
---
#### Gyroscope
Detect changes in gyroscope data:
```JavaScript
if(event.gyroX){
// do something
}
if(event.gyroX){
// do something
}
```
---
#### Cognitive Actions
Actions available:
- push
- pull
- lift
- drop
- left
- right
- rotate left
- rotate right
- rotate clockwise
- rotate counter clockwise
- rotate reverse
- disappear
```JavaScript
switch(cognitivAction){
case 2:
console.log('push')
break;
case 4:
console.log('pull')
break;
case 8:
console.log('lift')
break;
case 16:
console.log('drop')
break;
case 32:
console.log('left')
break;
case 64:
console.log('right')
break;
case 128:
console.log('rotate left')
break;
case 256:
console.log('rotate right')
break;
case 512:
console.log('rotate clockwise')
break;
case 1024:
console.log('rotate counter clockwise')
break;
case 2048:
console.log('rotate forwards')
break;
case 4096:
console.log('rotate reverse')
break;
case 8192:
