Brain-Computer Interfaces: Link to interview of Francois Vialatte, BCI researcher
Francois Vialatte is a Brain-Computer Interaction (BCI) research scientist at the Laboratory for Advanced Brain Signal Processing (ABSP), at the Brain Science Institute, RIKEN. Beginning in September 2010, he will be an assistant professor in the SIGMA lab, ESPCI ParisTech, in Paris, France. I'd like to share a link to his interview posted on the engineuring blog that focuses on Vialatte's research in the area of BCI, as well as the myths, misconceptions, and truths surrounding this fascinating area of study:

10 Interactive User Interfaces for the Future, Via Gizmo Watch; CNN's Eatocracy Site for Foodies - Food with Stories
I changed the name of this blog to reflect my focus on interactivity. The World Is My Interface is now The World Is My Interactive Interface.
In keeping with the change-of-blog-title, I thought I'd share a quick link to a recent Gizmowatch post, Ten Interactive User Interfaces for the Future. Bharat, the authro, reviews a variety of interfaces, input methods, and interaction techniques, such as Skinput, a water-based touch screen, a muscle-computer interface, air gestures, brain-computer systems, and even a mud-tub interface.
I was fortunate to see some of these interaction techniques and interfaces when I attended CHI 2010 this past April, and plan to share some of my photos and video clips on this blog soon.

Online connection for foodies
Eatocracy is a new website within the CNN pages that provides news- and more- about all things related to food. The categories on the site include "main", "news", "bite", "sip", "make", "think", and "buzz". The best part, in my opinion, is the heirloom recipe collection index, where people can upload and share family recipies and the stories behind them.
Here is the description of Eatocracy from the website:
Eatocracy "is your online home for smart, passionate conversation and information about food news, politics, culture. We'll highlight regional and family recipes, dive into restaurants and food shopping, chat with celebrity and local chefs, and show you what's for dinner around the world tonight. Grab a place at the table and read with your mouth full."
Enjoy!

Emotiv System's Neural Game Controller Headset: Human-Computer Interface of the future?
The June issue of the IEEE Computer magazine arrived in my mailbox today. As I thumbed through the pages, I noticed an article about "Emotiv", neural interface in the form of a headset that serves as a game controller.
In the course of looking up information for this post, I learned that Emotiv Systems will provide an open-source SDK for developers, which is great news for me. I'm a member of IGDA's Game Access SIG, and I've taken a couple of game design courses. I'd love to see what could be done with the SDK!
Another interesting piece of news is that Emotiv is partnering with IBM to look at how this technology can be used in for 3-D applications that reach beyond gaming, such as 3D virtual social environments, training, and simulations.

"Emotiv Systems introduces a sensor-laden headset that interprets gamers' intentions, emotions and facial expressions"
From the Scientific American article:
"By the end of this year, San Francisco–based Emotiv's sensor-laden EPOC headset will enable gamers to use their own brain activity to interact with the virtual worlds where they play. The $299 headset's 14 strategically placed head sensors are at the ends of what look like stretched, plastic fingers that detect patterns produced by the brain's electrical activity. These neural signals are then narrowed down and interpreted in 30 possible ways as real-time intentions, emotions or facial expressions that are reflected in virtual world characters and actions in a way that a joystick or other type of controller could not hope to match."
"The EPOC detects brain activity noninvasively using electroencephalography (EEG), a measure of brain waves, via external sensors along the scalp that pick up the electrical bustle in various parts of the furrowed surface of the brain's cortex, a region that handles higher order thoughts."
To see the Emotive Neuro headset in action, take a look at a video from the 1/9/08 Scientific American Video News: Emotiv's Mind Controlled Software Suite. Wearing the headset, you can make facial expressions that are replicated on the face of an on-screen avatar. You can move items around the screen through your thoughts. The Emotive system also relies on sensing the electrical activity of muscle movements.

"IBM intends to explore how the Emotiv headset may be used for researching other possible applications of Emotiv's BCI technology, including virtual training and learning, collaboration, development, design and sophisticated simulation platforms for industries such as enterprise and government." via Business & Games
Example of an application controlled by the Emotiv neural headset:
Note: There were problems with the application during the demonstration. Apparently the sound crew's AV headsets interfered with the system. This is something that needs to be tested in a variety of settings. If you live in a high-density area, you are bound to be surrounded by interference. This is why out-of-the-lab testing is so important!
Comment:
All of this intrigues me. I'm in the middle of neuropsychology training, learning the latest about neuroanatomy, brain function, and the evaluation and treatment of young people with traumatic brain injuries. I'm a member of IDGA's Game Access SIG. I'm also a school psychologist by day.
I know how much kids and teens might to explore this type of gaming. It looks like applications using this technology could be very useful to people who have a range of disabilities. What I'd like to see here is a way to connect the system to a haptic controller, like the Novint Falcon. Ideally, the system should work with other sorts of devices and systems.
I'm sure that in 2-3 years, the brain-comptuter interface will not rely on a headset. I'm thinking that the interface could work nicely in a "wearable", embedded into a "hoodie" or fashionable cap.

Discovery Tech: Upgrading Humans - Tracy Staedter chats with Desney Tan, Microsoft Research
"Well, we believe that there is a lot of potential to be harvested from interfacing directly with the human physiology... So we've done a lot of work with brain-computer interfaces, using brain-sensing devices to infer what's going on in our brains, which can be pretty useful in a variety of situations."
"We've also done quite a bit sensing muscles, and other parts of the body. Many of the technologies we use utilize very simple electromagnetic sensing, since the human body is a pretty prolific generator of these signals." -Desney Tan
