There were a few older papers that I missed in my feed, which have been added. No time to post a top 5 list today, but hopefully I will get into that groove soon. Enjoy!

Obama Day hooray

So, is anyone getting work done today? I'm getting a bunch of stuff done, but it's all that 'stuff that doesn't matter' type of stuff. I'm impressed that CNN managed to hold up under the number of viewers for the online stream.

Here's my first attempt at HDR photos from some of the Iceland pics. I'm pretty happy with how they turned out, especially since I spent only about 30 minutes on the (small) batch. A few are wonky and a few need better aligning, but the statue ones make me smile. Here's the Flickr set for the rest.

Anyhow, since I'm posting about nothing, here are the specs of the PC I'm building over the next two days:

CPU: Intel Core i7 940 (2.93GHz)
Mobo: EVGA x58 (they only make one)
RAM: 6GB DDR3 1600
GPU1: EVGA Nvidia Geforce GTX 295 (main display only)
GPU2: EVGA Nvidia Geforce 8600 GTS (for aux displays)
HDDs: 2x300GB 15,000RPM WD Velociraptors in RAID 0, 2x1.5TB Seagate drives (non-RAID)
Case: ABS Canyon 695
PSU: Seasonic 850W M12D
Monitors: My old Dells (24" widescreen main and 2x20" 4:3 aux)

...and it will be powered by the tears of children. Rahr!


brb... watching history...

Iceland presentation is available

Might not get SPF out today due to all sorts of insanity here, but I have posted the slides from the presentation in Iceland. They're in PDF format, and can be found here.

BCI for the kids

Yup, it's finally happened. The Consumer Electronics Show (CES) is going on in Las Vegas, NV and I'll post a research/cool gadget wrap up later. But, I thought it was worth noting that there are not one, but TWO BCI devices being marketed towards children. Both use EEG, so I'm sure they won't offer a frustrating and imprecise experience (note the sarcasm).

The most notable is the Mattel MindFlex. The user wears a headband with what looks like electrodes over the temples (+ ground to the earlobes), and navigates a ball around an obstacle course. The folks over at Switched (part of the Engadget universe) tried it out and found it almost completely unworkable. More coverage here, here, and a video here.

The second is marketed as The Force Trainer, a Star Wars toy, and all it does is train you to raise and lower a ball in a tube. Wheee! Ball goes up! Wheee! Ball goes down! What will your child will do after he or she 'masters' this game or decides that it's boring? I don't know, but whatever it is, I'd bet you could find out within 5 minutes of giving them this. These Gizmodo reader comments pretty much sum it up:
simi510: does it work or is a gimmick? IMO both. It works as a gimmick.
hofmann: My kids would honestly play with that for 5 minutes and then beat each other with it, and they actually like Star Wars.

What IS interesting about these toys is that there will be a generation of kids that have this idea of using neural signals to control external objects. If you read this blog, you probably grasp the basic concepts behind BCI systems pretty 'natively', but ask your average Joe on the street, and chances are you would have to explain the most basic ideas repeatedly before he/she could wrap their head around it.

The second interesting bit to come out of this is that no one knows the long term impact of 'training' yourself to repeatedly activate particular rhythms. I'm not being alarmist - oh noz! Johnny is dead from over training his brain! - but if you had a kid play with one of these for days, weeks, months, what changes might occur? We know that repeatedly engaging in 'mind altering experiences' (meditation, drug use, chronic stress, etc) can alter behavior significantly. What happens when a kid eats, sleeps and breathes The Force Trainer is unknown. Would it make them more docile and calm, or unable to focus on critical thinking? I guess we'll find out!

Thanks to the 50+ folks that showed up to the presentation yesterday. The place was packed to the back wall, and there were plenty of good questions and discussions afterward. I thought there would be 15-20 people, but the turnout was much better than expected. After the butterflies in my stomach settled, which was after everyone laughed at the Bjork picture instead of groaning, I had a great time. Of course, a big Thank You to Heida for setting it all up. I think the space was perfect, and the audience was very engaging, diverse, and friendly (even the guy with the mind-brain dichotomy questions - I love those discussions, but they can drag on for others, so I'm glad Heida cut it short when other folks started to glaze over).

Sorry about the accessibility problem at the location - the talk was held upstairs and there was no wheelchair access. When we found out about the issue Heida called several places to change locations and even a couple government departments to see if we could get some assistance, but it was too late. I am leaving tomorrow (the 7th) around 3pm, otherwise I would hold a second talk for those that couldn't attend, but at a more accessible location.

If anyone was unable to attend because of the access issue, catch me during the day today on the Reykjavik streets. I will be bouncing around town until around 8-9pm. Just look for the guy with messy/spikey hair wearing all black and dirty hiking boots, and carrying a laptop case and camera bag. I will also be at Babalu's (Babalú) around 7 or 8 (Skólavörðustígur 22a, city center), so email or reply to this post if you want to meet around then or later. Or earlier. I will check my email every hour or so today, so don't be afraid to just say, "Meet me at B5 at 6pm." If there are any conflicts, I'll pick a place and post it + email. Now that I think about it, Babalu's doesn't have wheelchair access either, but that is where my ride is picking me up. If you want to stop by and send someone up to grab me, please do so. If I am not there, I might have already been swept off to another location, so I will leave a note with the cashier if that happens.

I will possibly post the slides as PDFs, but want to clear it with the boss before I do. I know several people at CCP (makers of EVE Online) were unable to attend due to working late, so I'll see what I can work out. btw - CCP = Awesome work environment and friendly people.

Twas fun! Takk Fyrir!

Iceland presentation

I mentioned this in passing, but I will be giving a presentation in Reykjavik, Iceland tomorrow (Jan 5th) at 8:30pm. The talk will be at Balthazar's (Google satellite view, since no street maps available), which is a restaurant and bar, and is intended for a general audience. The invite has gone out to several university departments here, and from what I can tell so far, there should be a good turn out.

(I know, some people take offense to using the term 'cyborg', but there's a reason. I spent 15 minutes trying to explain what I do to a French girl who only spoke a little English. A friend leaned over and just said, "He makes Cyborgs", and she instantly understood. It's just easier. Plus, I didn't write the invite.)
