Shah was not using it very much now - because he had regained some movement in his finger - and this means that he will now have access to more traditional technology, such as a switch or maybe a computer mouse - very good news!<br /><br />The inevitable question is - did the Emotiv headset help Shah get his finger movement back? Shah is skeptical that it had any impact. However general feedback from some of those involved was that there was a possibility that he may have recovered some movement because of the increased brain activity from using the headset.<br /><br />This was not a clinical trial - it was an experiment to see whether such a device would help - so we will never know the true impact of it, or whether his finger movement would have recovered at the same rate anyway. But as his family told me, the headset demonstrated that it *was* possible for him to get some degree of personal control back, and that in itself was encouraging.<br /><br />And what about the headset? Would Shah recommend trying it to others in a similar position? Yes! Has he given up using it now he has another option? Nah - he's a techy at heart and likes to play with it - just like the rest of us!!<br /><br />Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com0tag:blogger.com,1999:blog-8814961153679656011.post-68493768807186204252010-10-18T05:53:00.000-07:002015-04-01T14:01:37.882-07:00Emotiv Headset and Locked In Syndrome<span style="font-size:100%;">In March, a salesman working for IBM had a stroke, which left him with complete paralysis, unable to use his muscles, and without the ability to speak. His brain however is working fine - a condition called Locked-In Syndrome. His means of communicating is by his eyes - looking up for yes, and down for no. He has to wait for someone to ask him if he'd like to speak before being able to do so. Then, using a letter chart, that someone must point at letters one by one, until a confirmation is received. This is the first letter of the sentence. The process must be repeated for every other letter in the sentence, until the full sentence is spelt out.<br /><br />The salesman in question is called Shah, and Sarah (my wife) is his Occupational Therapist (OT), who saw the mind-reading headset from </span><a target=""><span style="font-size:100%;color:blue;"><u>Emotiv</u></span></a><span style="font-size:100%;"> that I was using in IBM and thought about the potential this could have for Shah. The headset was designed for the gaming industry, and measures facial expressions, excitement/boredom levels and can be trained to listen for particular thoughts, which can perform an action on the computer.<br /><br />Sarah asked me to demonstrate it to the consultant, speech therapist, psychologist and hospital ward manager - who agreed it may have some potential, and who took it to the ethics committee. Shah was informed about the headset and what it can do - but that we weren't aware of any person with the symptom who had tried it before. Shah, being a bit of a techy, was up for pioneering it - so I met him last week for his first go.<br /><br />Just like the many other people I have demonstrated the headset with, Shah was instantly able to train the system so that one action - the "push" action - would push the floating "Emotiv cube" into the distance. As we trained, the ability to push (and stop pushing) at will, improved.<br /><br />Adding a second action adds a complication. Now the unit has to distinguish not just whether you think or don't think, but <i>which</i> thought you are having - much harder! And like everyone, it will take a bit of time to practise getting sufficiently good at this to control. However Shah is up for the challenge, and has a fantastically supportive family who are willing to help him train.<br /><br />Last week, after one week of use, Shah had managed to train the headset very well - though when tired the Emotiv skill can go down as well as up. Working with the speech therapist, we have connected the output of the headset to the input of </span><a target=""><span style="font-size:100%;color:blue;"><u>"The Grid 2"</u></span></a><span style="font-size:100%;"> - a piece of software by Sensory Software which allows a user, normally via eye tracking, keyboard, mouse or switches, to control their environment, write emails and surf the internet. We have initially set up 3 different menu items, and thinking "push" starts highlighted these options in turn at 10 second intervals. Thinking push again, will select one of the options. Sounds easy perhaps - but if I tell you to *not* think of a rabbit - you can't help but think of a rabbit! It's hard to think about when to start and stop thinking, and then change to think about the thought you are supposed to be thinking about! I think this will take some practice to achieve, but once achieved could be widened to many more options, with very little extra practice.<br /><br />Often people ask about using the headset for people with different conditions, and in different places. What with Shah being a fellow IBMer who likes gadgets, and his OT being my wife, and with the particular medical condition he had, conditions were ideal to try out the headset. It will take time for us all to get it right - but for now it is looking good. I will try to keep you updated!</span>Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com1tag:blogger.com,1999:blog-8814961153679656011.post-9357461056715815532010-05-27T04:30:00.000-07:002015-04-01T14:01:37.894-07:00Wearable computing devicesTime to do a bit of blogging again.

The technology is supplied by <a href="http://www.neurosky.com/">NeuroSky</a>, who have also provided the technology for a <a href="http://www.neurosky.com/products/force-trainer/">Star Wars game</a> - $50-$100 for the fun of using "brain waves to allow players to manipulate a sphere within a clear 10-inch-tall training tower..." - something I could imagine myself doing just the once. Never-the-less it's quite good to see the technology coming down in price.<br /><br />What fascinates me however is how we might be able to use brain waves for real personal benefit and integrate it more with our every day computer interaction experience. People who have severe motor difficulties could use it as a <a href="http://www.thelancet.com/journals/laneur/article/PIIS1474-4422%2808%2970223-0/abstract">rehabilitative aid</a>. Performing product research, it can be used for detecting when people are excited or not when they experience a particular product or website. When we are browsing on-line, we could combine it with <a href="http://en.wikipedia.org/wiki/Eye_tracking">eye tracking</a> to provide feedback on what really interests us, and then tailor our online experience accordingly. When we go to the shops... the cinema... driving in the car... feedback can be provided to enterprise systems in all sorts of situations, which in turn can affect the environment around us. I'm really looking forward to talking with a number of customers about how they can integrate this and other interface technology in their own innovative projects in 2009!Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com0tag:blogger.com,1999:blog-8814961153679656011.post-41028569376161170372009-01-06T08:59:00.000-08:002015-04-01T14:01:37.841-07:00Calculating energy usage is harder than it seemsIn my last post, I said a Christmas project was to monitor my usage - but I confess I've got a problem of how to measure my energy usage which is so far unsolved.<br /><br />As I said, I have a <a href="http://www.currentcost.com">currentcost</a> meter (m1) which reads the current going into and out of the house. Of course, it cannot determine which way current flows, so it reads 50W regardless of whether the 50W is imported to, or exported from, my house. Therefore, I put a second meter (m2) round the wire from the solar panel, which told me how much the panel was generating and was thinking that if the value on m2 > m1 I must be exporting, otherwise I would be importing. However this thinking is flawed:<br /><br />If I am generating 100W, (m2=100) and I am using 50W, then I will export 50W (so m1=50).<br />If I am generating 100W, (m2=100) but I am using 150W, then I will import 50W (so m1=50).<br /><br />So from my two readings, I cannot conclusively say whether I am importing or exporting electricity, unless I am missing something obvious? The bright green import/export meter which Southern Electric fitted manages to work out what is being imported and what is being exported - but there doesn't seem to be a nice little serial port anywhere obvious! The other option is to buy a wireless unit as an addition to the inverter but this costs £120 and doesn't appear to give me open access to the data.<br /><br />BTW - in 20 days we've generated 16.2 kWh and exported 9 of them. A grey day typically generates 200Wh the whole day - a sunny winter's day like today seems to generate about 2kWh.Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com4tag:blogger.com,1999:blog-8814961153679656011.post-65509156460796362222008-12-18T15:24:00.000-08:002015-04-01T14:01:37.870-07:00The solar works<span style="font-weight: bold;">In the loft</span><br /><a style="font-weight: bold;" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3hVwVY_UOrK29NjJB1hLxmc8ozf_VaOpz3jbFhDy1vMvZKSfWIjUr7BxKCaNI_8FPJJJDbDOWYF46w-MKhf_fNAFyR7XLnv0hGzKntV5JVBBtY00WMmXirj604ReqddgEgZsTrqqb1e0N/s1600-h/18122008290.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 170px; height: 128px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3hVwVY_UOrK29NjJB1hLxmc8ozf_VaOpz3jbFhDy1vMvZKSfWIjUr7BxKCaNI_8FPJJJDbDOWYF46w-MKhf_fNAFyR7XLnv0hGzKntV5JVBBtY00WMmXirj604ReqddgEgZsTrqqb1e0N/s320/18122008290.jpg" alt="" id="BLOGGER_PHOTO_ID_5281276048072864978" border="0" /></a>The solar panels are connected to an inverter (right - click photos to enlarge) , which converts the DC generated current into AC, using the "only clever bit" of the entire installation, according to the installer. This is mounted just inside the entrance to the loft. The interesting thing about the blue box is the "knock interface"... to switch on the unit and light up the screen you have to knock on the grey area. The screen tells you how many watts the panels are generating, and how much have been produced during the day, and how much in total.<br /><br /><span style="font-weight: bold;">In the kitchen</span><br /><a style="font-weight: bold;" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhvHqibj3yMyaNKUijoCeWnigmQzwfazxAnv8HfnO2gG_21qA4obURQflDlh58HmQUGjkPqEnHtKokOaPW_hyphenhyphenAcX_fyQFT6PJyZAVmEsWJsdFX_fnCeRitt9X8Ex0qOYZKe530dwDF3OtRE/s1600-h/18122008291.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 171px; height: 127px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhvHqibj3yMyaNKUijoCeWnigmQzwfazxAnv8HfnO2gG_21qA4obURQflDlh58HmQUGjkPqEnHtKokOaPW_hyphenhyphenAcX_fyQFT6PJyZAVmEsWJsdFX_fnCeRitt9X8Ex0qOYZKe530dwDF3OtRE/s320/18122008291.jpg" alt="" id="BLOGGER_PHOTO_ID_5281276051679568498" border="0" /></a>Downstairs, next to the consumer unit is a fantastic red knob, which isolates the panels. Above it is a meter which also shows how much electricity has been generated by the panels in total. During the first day of operation, the unit generated a total of 700W - disappointing considering it was bright sunshine outside all day, and the unit is spec'd at 1000W <span style="font-weight: bold;">per hour</span>. The installation engineer reassured me that as the sun got higher during the summer months the unit would generate much more - we shall see! During the second day of operation, when it was cloudy, the unit generated a total of just 200W during the day.

The meter gives the amount exported to the National Grid (ie total produced by the solar panel minus total consumed at the time in the house), and also the amount imported from the Grid. You can see the current cost clamp in the picture. This is interesting, because the current cost meter measures the flow of electricity regardless of which way it flows... so it reads 100W when the house consumes 100W, and it reads 100W when the house exports 100W. It was highly confusing turning on a light to see the amount on the meter decrease! So one of my Christmas projects is to connect another meter to the solar panel cable, and add the two readings together in order to get a sensible output... more on that later.Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com2tag:blogger.com,1999:blog-8814961153679656011.post-58886785328262684132008-12-16T05:23:00.000-08:002015-04-01T14:01:37.845-07:00Solar Panel installation<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgUd_qtjeoLEx5y64p7IiiETpmJJhbEe2XO1dlBwW3HJSUEAjWcFR1KnrKRIn2aKhRK336BtBcreLhYxJure3TuQ96XnhI655df8Eg7HJDk4ekhhvZ4EtPnSq7CwmiTSMdAVATS2Tj9sSlM/s1600-h/DSC00887.JPG"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgUd_qtjeoLEx5y64p7IiiETpmJJhbEe2XO1dlBwW3HJSUEAjWcFR1KnrKRIn2aKhRK336BtBcreLhYxJure3TuQ96XnhI655df8Eg7HJDk4ekhhvZ4EtPnSq7CwmiTSMdAVATS2Tj9sSlM/s320/DSC00887.JPG" alt="" id="BLOGGER_PHOTO_ID_5280387177438446258" border="0" /></a><br />Here's a photo of the solar panels which were fitted to our roof today by <a href="http://www.rayotec.com/solar_power/">Rayotec</a>. They should provide us with 1kW electricity per hour in peak sunshine, but just around 100W per hour in horrible foggy weather like today. Tomorrow morning they will be grid connected, so any extra electricity we don't use will go back into the grid. With Southern Electricity giving us slightly more per unit than we pay for our electricity, there's still an incentive to use as little as we can. We expect the unit to just about cover our usage, over a yearly period. It cost around the same as having all our doors and windows replaced a few years ago and we're promised a similar length of service. So, we're just looking forward to the grand switching-on ceremony tomorrow morning!Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com3tag:blogger.com,1999:blog-8814961153679656011.post-29684439283764835672008-11-24T09:04:00.000-08:002015-04-01T14:01:37.816-07:00Mind reading headsets<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.ocztechnology.com/images/products/accessories/b/NIA_headband_1_big.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 452px; height: 350px;" src="http://www.ocztechnology.com/images/products/accessories/b/NIA_headband_1_big.jpg" alt="" border="0"></a><br />So far, the mind reading headset market aimed at the regular consumer is quite small... I've come across the well advertised <a href="http://emotiv.com/">Emotiv</a> headset, to be released early next year, and OCZ's "Neural Impulse Activator", shown right.<br /><br />Unlike the Emotiv headset, with 16 different sensors placed on different parts of the head, this unit only has 3, all placed across the forehead, inevitably giving slightly less function.<br /><br />In the first several hours of playing with the device, I managed to work out what successful calibration "looked like": - when the muscle signal graph didn't vary away from the "desired baseline". Sometimes this was very easy to achieve, and other times, just didn't happen. I discovered it worked better on one side of the lounge at home, than on the other. I also concluded that wetting the 3 sensors with water helped to a degree. Unfortunately the device needs to be calibrated every time it is used, which makes demonstrations rather hit-and-miss.<br /><br />My first successful experience came shortly after calibrating the device. I was able to play the game of pong, using my eyebrows. By wiggling them fractionally upwards, the bat went up, and wiggling them downwards, the bat went down. And whilst I didn't ever manage to win a whole game, I did hit the ball enough times to win a few points, so it was not all chance.<br /><br />My other successful experience was linking the muscle movements to keypresses, so I could use my eyebrows to navigate around Google maps. An eyebrow up-wiggle mapped to Page Up, and sent the map flying in one direction, a down-wiggle mapped to Page Down, and sent it flying in the other. Unfortunately zooming in and out was a bit beyond me, as the '+' key was unmappable.<br /><br />So how is this mind-reading? Well, unfortunately it isn't yet. Unlike the Emotiv device, it seems impossible to "train" the device to recognise when you are thinking of stroking a cat for example. As found in this <a href="http://techreport.com/discussions.x/13928">review</a>, it should be able to detect general mood - OCZ's VP Dr. Schuette, says he can think of an expletive to make his Alpha 2 increase enough to trigger a "jump" action in his computer game. However I suspect this takes many hours of practice!<br /><br />So for now, I shall continue playing pong with my keyboard, and wait for a few weeks when I hope to be able to get my hands on the Emotiv headset.<br />Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com0tag:blogger.com,1999:blog-8814961153679656011.post-33574730858197959012008-10-24T15:46:00.000-07:002015-04-01T14:01:37.824-07:00I recently bought a <a href="http://www.viglen.co.uk/webmail/pdfs/MPC-l.pdf">viglen MPC</a>, and installed Xubuntu it using some very good <a href="http://stanford-clark.com/viglen.html">instructions</a> from Andy SC. I added a USB dongle for wireless, and another one for bluetooth (for later experiments). I then linked my <a href="http://www.currentcost.co.uk/">current cost</a> meter to it, to try out some <a href="http://cid-14811d3c96ccaad2.skydrive.live.com/self.aspx/Public/currentcost-python.zip">code</a> from <a href="http://dalelane.co.uk/blog/?p=297">Dale Lane</a><a href="http://dalelane.co.uk/blog/?p=297">'s blog</a>. I first needed to install a number of pre-reqs, so I thought I would document them here.<br /><br />First, I expanded the currentcost-python.zip into a directory, and ran the code:<br />sudo python currentcost.pyc<br /><br />This gave an ImportError for module wx. Although I tried installing easy_install, this did not install anything successfully for me, so I followed these <a href="http://wiki.wxpython.org/InstallingOnUbuntuOrDebian">instructions</a> to install the wxpython modules. Next, the following commands allowed the other pre-reqs to be installed:<br />sudo apt-get install python-numpy<br />sudo apt-get install python-matplotlib<br />sudo apt-get install python-serial<br />sudo apt-get install python-simplejson<br />sudo apt-get install python-pysqlite2<br /><br />The application then worked! To determine which port to use, I typed:<br />dmesg | grep tty<br /><br />The third line of the output said "converter now attached to ttyUSB0"<br />When you connect, the port should therefore be: /dev/ttyUSB0<br /><br /><br /><br />Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com0tag:blogger.com,1999:blog-8814961153679656011.post-36268398103534979802008-10-14T13:30:00.000-07:002015-04-01T14:01:37.837-07:00How to communicate if you can barely moveMy wife works with people who have had head injuries or strokes, who cannot move from the neck down and sometimes cannot talk; some are mentally active, which must be even more frustrating. Even in this day of great technology, letters are drawn on paper, and letter by letter the person moves their head from one side to the other side to indicate if this is the next letter in the sentence. As you can imagine, this takes a very long time, and it cannot be used to initiate a conversation.<br /><br />Recently, I've been playing with a very good piece of software aimed at eye tracking called <a href="http://www.inference.phy.cam.ac.uk/dasher/">Dasher</a>. This allows letters, which move in from the right of the screen, to be selected one by one by moving the mouse up and down and gradually forming a sentance. It is also predictive, so if for example you have selected H and then e, llo would be close together. It runs on multiple operating systems.<br /><br />Secondly, my colleage <a href="http://twitter.com/ceejay">Dave CJ</a> has created a fantastic python script to control the mouse pointer on a Ubuntu PC using the accelerometer on the Nokia N95 via bluetooth.<br /><br />So... by combining the two, I can tilt the N95 from side to side, to move the mouse on the PC and select letters in a sentence. OK, so balancing a phone on your head looks slightly stupid, but if it helps open up a means of communication without any specialist equipment, or the help of someone else, it surely must be a good thing.<br /><br />Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com0tag:blogger.com,1999:blog-8814961153679656011.post-74258086035537651652008-09-15T06:37:00.000-07:002015-04-01T14:01:37.890-07:00I've changed my name, thanks to GoogleHaving a common name like Kevin Brown is a bit of a problem when it comes to getting a consistent, unique id on the various different web sites like blogger, twitter and the like. I have experimented with a range of ids... but over this weekend I decided I'd go for a more radical option - to change my name.<br /><br />I had a search on Google and discovered that kevinxbrown, kevinybrown and kevinzbrown all returned no search results - which surprised me a lot! Have no other Kevin Brown's in the world got a middle name starting with these letters? So I've now adopted the middle name Xavier (well, what other names start with X?) Sorry to my twitter community who I totally confused over the weekend with my little identity crisis - ignore my invitations - I think I'm back in one piece as <a href="http://twitter.com/kevinxbrown">kevinxbrown</a>.<br /><br />Yours forever (or until the next name change), Kevin Xavier Brown.<br />Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com1tag:blogger.com,1999:blog-8814961153679656011.post-66630947456193271552008-09-03T07:31:00.000-07:002015-04-01T14:01:37.878-07:00Emerging HCI technologies<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://farm1.static.flickr.com/121/273269366_38d4644ea2.jpg?v=0"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 320px;" src="http://farm1.static.flickr.com/121/273269366_38d4644ea2.jpg?v=0" alt="" border="0"></a><br />I find it very old fashioned and frustrating to sit down in the office every day and look into a box, whilst pressing my fingers rapidly on little pieces of plastic representing letters, and moving a small plastic box from side to side. It's not natural and can't be that healthy - ignoring the mandatory pizzas and <a href="http://en.wikipedia.org/wiki/HobNob">Hobnobs</a> consumed whilst doing so. The QWERTY keyboard was patented in 1878, and the mouse is 40 years old - so given the advancement everywhere else in technology, it's about time we got something else that beats it.<br /><br />The good news is there are <a href="http://news.bbc.co.uk/2/hi/technology/7508842.stm">many exciting technologies</a> which are either newly with us, just around the corner or have been reduced to a price which is accessible for the average user. I've been following some of them, such as <a href="http://www-01.ibm.com/software/pervasive/embedded_viavoice/">embedded ViaVoice</a> for talking to machines in a natural way, "mind reading" headsets such as the one from <a href="http://emotiv.com/corporate/2_0/2_1.htm">Emotiv</a> aimed at gamers and due for release in December, <a href="http://www.microvision.com/wearable_displays/index.html">wearable displays</a> which allow you to augment reality with your own data - and <a href="http://www.microvision.com/pico_projector_displays/index.html">mobile phone projectors</a> all to be released in the next few months - as well as haptic user interfaces like this <a href="http://news.bbc.co.uk/1/hi/technology/7593444.stm">ultrasound device</a> written about on the BBC today. I think the next few months and years will be very exciting! Just been playing with an <a href="http://www.ocztechnology.com/products/ocz_peripherals/nia-neural_impulse_actuator">OCZ NIA</a> but that's a post all of it's own....<br /><br /><br /><font size="1">Image: http://www.flickr.com/photos/truebluetitan/273269366/</font><br />Kevin X Brownhttp://www.blogger.com/profile/01420461034123257268noreply@blogger.com0
