User Interface/User Experience Technology Tutorial: EMOTIV's EPOC+ 14 Channel Mobile EEG Neuroheadset


We all know headsets, but what if there's a way to use our brain and thoughts to do that feature. Well now we can by using Emotiv's EPOC neuroheadset which is created by Tan Le, the co-founder of Emotiv. In this tutorial there would be mention of how to use it, what it can do, and what are the requirements, setups, and mentioning it's features. I will also put down the links where I got these sources for my research. 





Features: It's easy to fit and with flexible design. EPOC is wireless and can be rechargeable with dense array spatial resolution ensuring the "whole brain" measurement. This headset has saline based wet sensors, so there would be no sticky gels and it's battery is lithium which can provide up to twelve hours of continuous use. EPOC neuroheadset is compatible with Microsoft Windows, Mac OSX, Linux, Android, and iOS software devices. The neuroheadset also provides access to Raw EEG (Electroencephalogram) data with software subscription as well as access performance metrics, mental commands, and facial expressions.

Microsoft's Windows Hardware and Software Requirements: 2.4 GHz Intel Pentium 4 processor or equivalent, Microsoft Windows XP with Service Pack 2 or Windows Vista, 1 GB RAM, 50 MB of available disk space, and one or two unused USB 2.0 ports which it all depends how many neuroheadsets you want to use at the same time.

USB Receiver Installation for Windows: Plug in the provided Emotiv USB receiver or receivers into an unused USB port on your computer device. Every receiver should be recognized and installed automatically by the computer as a USB Human Interface Device. No additional hardware drivers are required to be installed and wait a moment until your system shows the hardware is ready to be use.

Emotiv Xavier Installation for Windows Step 1: Use Windows Explorer and access the Emotiv Xavier SDK version 3.0.0.x Installer.exe or Emotiv Xavier SDK version 3.0.0.x-PREMIUM Installer.exe where you can download from Emotiv's website (https://www.emotiv.com/).

NOTE: Couldn't find any sources that tells anyone about the hardware and software requirements for both the Linux Operating System and iOS. 

Setting up Emotiv Xavier SDK: Now, to set up your device the set up tab is set as your default when first starting up the Emotiv Xavier SDK software. The main function of this device is to display contact quality feedback for the headset's EEG sensors provides guidance to the user who's wearing it correctly. According from Emotiv it's very important for anyone to achieve the best possible before proceeding to other tabs of the SDK software.

Setting Up Your EPOC Neuroheadset Step 1: You need to switch on the headset and confirmed that the built in battery is charged and also providing power by looking for the blue LED located near the power switch at the back of the neuroheadset. If it needs to be charge then turn off the power and plug it into the Emotiv battery charger by using the mini-USB cable which comes with the headset once you purchase it from Emotiv's website. Please allow this headset to charge for approximately fifteen minutes before attempting to try it again. Warning, do not attempt on wearing the headset while it's charging.

Setting Up Your EPOC Neuroheadset Step 2: Then verify the Wireless Signal reception is good by checking out the EPOC status area in the pane. If you see the signal status showing bad; therefore, make sure Wireless USB receiver is inserted into a USB port on your computer and the single LED is flickering very rapidly on the top half of the receiver. If the LED light is blinking slowly, remove the receiver from your computer and then reinsert it to try again. Make sure to remove any metallic objects or obstructions that's located near the neuroheadset also move it away from any devices with powerful sources of electromagnetic interference like microwave ovens.

Setting Up Your EPOC Neuroheadset Step 3: You can now put on the EPOC neuroheadset by gently pulling apart the headband and lowering the arms of the sensors onto your head from the top down which is near the rear of the skull. Slide the headset forward until the sensors is closer to the headset pivot points which are located directly above your ears, but as close to the hairline though. If you didn't adjusted the fit then the rectangular compartments on the front end of the headband, it won't feel comfortable both above and behind your ears. Also tilt the headset so that the lowest, front most sensors are symmetric onto the user's forehead and position two to two and a half above the eyebrows. Check all of the sensors are touching the head if not, fine tune the headset by gently sliding in small addition until satisfying the fit has been attained.

Setting Up Your EPOC Neuroheadset Final Step: Please repeat this for the remaining sensors until all of them have accepted contact quality.

I believe this product will be successful because if you watched the demo video (http://www.ted.com/talks/tan_le_a_headset_that_reads_your_brainwaves?language=en), it apparently works very well and if this type of headset incorporates into the gaming industry then it'll be even more successful. What I think is neat about this technology is that we carry out commands by thinking the thought while wearing it because our brains generates different kinds of brainwave patterns. This will change gaming because we always use our brains for playing video games like solving puzzles, thinking of strategies, and controlling our characters with only a keyboard and a mouse or with a controller. What if we can do all of that by just using our minds like controlling our avatars to do whatever comes up in our heads instead of using our hands to use the keyboard and mouse. Also what we're thinking while playing a game will automatically pop up onto our screen. One specific feature about this product that caught my attention is it's easy to fit with a flexible design. This feature caught my attention because when I saw the first photo of it I thought to myself "How the heck that thing is flexible?" Once I found a link to a demonstration video it blew my mind and how flexible this headset is as well as how incredible people can just slip it right onto their skulls without any problem(s). If I designing a game, I will incorporate this product to be part of a side scrolling, 8-bit, beat em up video game. I would incorporate it into that type of game because I will have users use their minds to make the characters to pick up a weapon or punch an enemy once they it on screen and the plus side the EPOC is compatible to work on both the PlayStation 3 and PlayStation 4 which is one of the consoles my video game's targeted platforms.
