Event triggering synchronization tutorial between OpenSesame 1 and Emotiv EEG Testbench 2, facilitating the use of Emotiv EPOC 3 wireless Brain Computer Interface device in cognitive research experiments1 is a state-of-the-art graphical, open-source experiment builder for the social sciences.2 is a raw EEG research data recording software included with the Research SDK of Emotiv EPOC.3 is a revolutionary 14-channel wireless Brain Computer Interface and Scientific Contextual EEG device for research enabling entertainment, market research, usability testing and neurotherapy. Hardware Requirements. One (1) workstation operating on OS X or Linux (Workstation #1).

One (1) workstation operating on OS X or Linux (Workstation #2). One (1) Fast/Gigabit ethernet network switch & a pair of ethernet UTP/STP patchcords. One (1) Emotiv EPOC unit. One (1) USB Serial adapter supporting OS X, only if OS X version of Emotiv Research SDK (Testbench) will be used in Workstation #1. This is critical If you are using a modern version of OS X (10.8), as due to OS restrictions a serial port -as expected by Testbench (/dev/cu.)- cannot be created otherwise.

Thus, even if in the final setup this USB Serial adapter will not be used effectively, connecting it to workstation #1 will allow us to enable the required by Testbench serial port. For the purpose of this tutorial a was used and its appropriate driver was installed. Software Requirements. One (1) Emotiv Research SDK (EEG) license (includes Emotiv Testbench software) selected for the OS of Workstation #1. Latest version of OpenSesame, selected for the OS of Workstation #2. socat installed in both Workstation #1 and #2.

For OS X, first install. Then: brew install socat. For Linux, install using its packager (apt/yum); e.g. For debian/ubuntu use: apt-get install socatsocat?. is a relay for bidirectional data transfer between two independent data channels. Each of these data channels may be a file, pipe, device (serial line etc. Or a pseudo terminal), a socket (UNIX, IP4, IP6 - raw, UDP, TCP)., or a combination of two of these.

These modes include generation of 'listening' sockets, named pipes, and pseudo terminals. We will use socat to setup a UDP stream between the two workstations, linking a virtual serial port in each workstation with this stream. We wil also link each virtual serial port with another (physical or virtual) serial port in each workstation. The latter ones (serial ports) will be used by the corresponding software in each workstation (i.e. Testbench in Workstation #1 and OpenSesame in Workstation #2).So, the concept is. Conventionally, both Emotiv Testbench and OpenSesame are supposed to be linked with a physical serial port to receive / send markers accordingly. Here, instead of connecting physical serial ports between the two workstations with a physical cable, we will be using virtual serial ports and a virtual 'cable' (i.e.

UDP stream between the two network hosts) instead.Let's proceed with an example. Two (2) MacBooks (OS X) will be used here. OpenSesame is installed In Workstation #1 and Testbench is installed in Workstation #2. Configure TCP/IP settings using IP#1=192.168.0.1/24 in Workstation #1 and IP#2=192.168.0.2/24 in Workstation #2Workstation #1. In Workstation #1, connect the USB Serial adapter in a USB port (after having installed its driver).

Then, open Terminal application (found in Utilities) and use the following command in one line.

Here at GSMArena, phones and tablets are our bread and butter, but our love for tech is by no means limited to them. So imagine our excitement when we got the opportunity to test a gadget which reads your thoughts and allows you to do cool things with it on your computer.The gadget in question is called EPOC and is made by Emotiv. It’s a futuristic looking headset, which reads your brain activity via the scalp of your head and translates it into various actions. With that in mind, I was particularly excited with Professor Xavier and his powerful telepathic powers immediately popping into my head. Sadly, this isn’t the case yet.The Epoc is a neuro-signal acquisition and processing wireless headset. It uses 16 sensors to capture the electric signals produced by your brain.

Put simply, it’s a thought detector. But alongside this, it’s also a feelings and expressions grabber, so if you blink, smile or sneeze – it’ll know. Let’s take a closer look at the product itself.

UnboxingEmotive has packed the EPOC headset in a handy box sporting a minimalist design. It has a handle on top so you can easily carry the headset around.

Emotive has thrown in everything you need to get started, which is kind of them, as chances are you don’t have the accessories just laying around your house.Back to the contents of the box at hand, inside there’s a 16-pack of contact pads, which are placed in sockets on the headset to make contact with your head. To improve the signal strength there’s also a bottle of conductive liquid to keep those sensors hydrated. There’s also a USB receiver to connect with a computer, as well as a miniUSB cable and an instructions manual with a software CD.Design and constructionThe Epoc headset is entirely made of plastic has a base similar to a regular pair of headphones. Where it differs are the two octopus arm-like extensions which warp around your head. They are flexible in order to get the best possible contact and at the end have sockets for the soft contact pads.

At the top, there’s a switch for turning the headset on or off.User interfaceEmotiv have designed a specialized software, which shows the EPOC’s capabilities. It’s broken down to five different sections:The first one acts as a status check for all the contact pads. They light in four different colors: green for great connection, yellow of okay-ish connection, red for bad connection and black for no connection at all. Preferably, they should all light up green, but we’ve had cases where the headset worked perfectly fine despite a few red or yellow sensors.However, when I tried it everything went green and I felt like a Jedi summoned to protect the universe from the Dark side and bring balance to the Force. The other tabs really showed me what the neuroheadset is all about.Called “Expressiv suite”, the second tab shows a blue face, which actually mimics the facial expressions that you are doing at the moment. So if you blink, it blinks.

If you smile, it smiles, and so on.Next up is the “Affectiv suite”. As its name suggests it detects what affects you at the moment and displays your current emotions on the screen.

Those can be happiness, indifference, etc. It’s pretty cool to observe at first but you quickly get bored. Unlike it, the next tab labeled “Cognitiv suite” is where the meat is.In the Cognitiv suite you get to control a virtual cube using just your thoughts. There are various operations that you can do with it like push it backwards/ pull it towards you, make it go up or down or even rotate it in various directions.Here’s a video where we try to show the whole magic taking place. We first demonstrate how the software captures brainwaves and translates them into actions on the screen. Then, we get to the really interesting stuff – playing a game, where you control the main character with the headset.I can assure you I didn’t use a keyboard, mouse or any other input device to control what was happening on the screen. The neuroheadset was the sole initiator of each and every action.

Of course, I had to use the mouse to navigate around the applications, as well as in-game for going forward and left/right.More and more applications, games and other utilities making great use of the headset are being published each day, so it’s definitely interesting to see how far the technology might go in the next one or two years. ConclusionThe Emotiv EPOC will not turn you into a Jedi, but it’s a solid step into the future of doing everyday tasks with your mind. Imagine turning your PC on or off by just thinking about it, or pausing a movie when you need to grab some more snacks.Let’s not forget the people with disabilities, who can use the full potential of a personal computer with nothing but their thoughts. This can and should rewrite the history of computer interaction, but unfortunately, the technology isn’t quite ready just yet.For now, the Emotiv EPOC headset is little more than a gimmick. A nice gadget to show off to your friends and make them scratch their heads in disbelief, until they realize there’s little practical use for it. Its future however is much bigger than this or at least, that’s what we hope. Posting rules.
