A Third Eye on Technology

In many office environments today it is common for mid and upper level employees to have their own corporate laptop that they carry with them everywhere they go and attach it to a dock station either at their desk at work or at home, which allows quick connection of the laptop to a traditional keyboard, mouse and monitor.  With the advances in CPU technology as of late and predictions of many new smart phones this year being equiped with quad-core processors, it has gotten some who use such laptops in office environments wondering if they still need to carry big old clunky laptops around just for the sake of processing power.  Well if you are such a person you’ll be in for a treat this year as the smart phone as we know it today is about to make many laptops obsolete.

Canonical has just announced their intentions of releasing Ubuntu for mobile smart phones this year, targeting business as well as consumer markets and allowing many current Android phone users the ability to install Ubuntu on their phone as an alternative in the coming months for free.  Quad-core processing power in smart phones seen this year will  approach the kind of processing speed you normally see on entry to moderate level PCs today (think Intel i3), which is more than necessary for a lot that people do on their desktop or on their phone for that matter.  The mobile version of the Ubuntu OS will be available for many Android users for free in the coming months and for those with the latest and greatest phones to hit market they’ll be able to use the phone as a complete desktop replacement via a dock much in the same way many laptops currently do.  It’s very exciting news!  I’m not going to ramble on here about how or why this is going to happen as head of Canonical Mark Shuttleworth has already done so in this proposal video where he speaks about the immediate goals for Ubuntu.

Okay, probably not the first in my life time, but since I can’t remember any other in my past I’m gonna just say this is the first.  Probably last too.

For several months I’ve had a server with a monitor, keyboard and mouse  plus a wireless router cluttering the back side of the livingroom in my home and decided to migrate this stuff into a room that’s at the far end of the house (“far” end meaning “further away from where my computer is, aka the cave).  So the only thing left in the living room was a cable modem which now connects to a 25 foot long Ethernet cable that leads to the router in the next room.

The drawback I knew I’d probably run into with this is the good chance that my wireless network connection would nearly be crippled.  I don’t have a big house, but I was going to be adding a couple more walls in between my computer and the router.

Now, I don’t go around talking too much about playing video games, but lately I’ve been on a streak of Left 4 Dead 2 because my best friend Jordan asked me to get it so we could play together online.  Games like that demand the best of connections that you can muster, and adding another gap of lag between myself and those game servers got me worried.  I haven’t yet tried to do multiplay since the move, but did notice that my wifi said that my signal was now “Very Low”.

So I pulled out my new Nexus One cell phone with Android Linux on it and fired on an app I got from the market for free called Wifi Analyser.  It kind of looks like this:

Above is just an example image I found with Google. What this program will show you is a line graph that displays the radio frequency usage of nearby wireless networks.  You see, wireless networks are kind of like walkie-talkies.  If some kid in your neighborhood is using the same radio frequency as you, your signals will obviously overlap and interfere with each other.  This app is made to quickly show you what frequency ranges are the most used in your immediate vicinity.  In my case I had quite a lot of overlap.  So I logged into my router, changed the wireless channel from 6 to 11 and that made a world of difference.  Windows says my signal is “Very good” now.

If you don’t know how to log into your router a good website to consult about this is portforward.com.  This site is intended to be used as an interactive guide that shows you how to login to your router and change your port forwarding configuration.  So the only part you need to pay attention to is the first half that shows you how to access your routers configuration settings.  The last half can be tossed aside.  Router configuration is a lot like browsing a website that has different check boxes, fly-outs and text fields for you to manage.  Just click around until you find something that says “wireless” and look for a setting that pertains to the radio channel it’s using.  The default for most routers these days is 6, or sometimes “auto”.  If it’s auto, you can at least experiment with it to see if based on your observations there is a frequency range that is more open and less cluttered than one it’s currently using.  And if it doesn’t seem to help your performance any, the change can be reversed.

Having the same phone for more than two years tends to wear on you.  I’ve never had a true “smartphone” before, short of playing around with the iPhone I bought my girlfriend for her birthday last year so getting this little gizmo was a big deal for me.  There’s a lot I love about the phone, namely the Android Linux OS that runs on it, but also that beautiful AMOLED screen which absolutely trumps the current selection of phone out there.  No phone has a screen this crisp and vivid right now.

Blah blah blah, this phone is pretty damn nice.  Enough said, really.

You’re walking through the entertainment department at your local shopping center and pick up a DVD that you’d like to see.  You scan the bar code on the back of the DVD with your cell phones camera.  By the time you get home, the movie you looked at while shopping has already been downloaded to your PC.  Check this video out to see how it works:

It goes without saying that downloading a movie illegally via bittorrent is probably going to piss the MPAA off.  But if they’re smart about this, they could actually take the concept of scan-to-download idea and turn it into a big money maker.  There’s probably plenty of people who would purchase a digital download of a movie if it were offered to them at a reasonable price.  Just take a look at iTunes or Amazon offering DRM-free MP3 merchandise.  You might even take a look at what Valve Software did with Steam recently:  They cut the price of Left 4 Dead by 50% and noticed a 3000% increase in sales.  Ultimately it just goes to show that there is an ever increasing number of people who want to purchase digital merchandise and they’re willing to pay for it as long as it’s not overpriced.  I could even see movies being offered up for free with commercials inserted in a hulu.com style.

Anyway, cool app for a cell phone to say the least.  Thought for pirates, it would be kind of like saying, “Hey.  As if my IP address weren’t enough information, here’s my phone number too.”

This is what you get when you combine a portable video projector, a camera and a cell phone that has access to the Internet and the ability to process visual information for you.  Simply amazing!  Click on the video below to see a demonstration.

As cool as this technology is, I have to say that I think it’s already up against some stiff competition from smart phones like the Google Phone and the iPhone.  For instance, the video shows a demo of evaluating different kinds of paper towels for the user so they can pick out the one that is the most environmentally friendly.  A somewhat similar application that already exists on the Google Phone (and others before it in Japan) is a program that allows you to use the built-in camera to scan the products UPC barcode, which would then give you an instant price check for that product at local stores and even through online merchants.

It would take little effort to expand the capabilities of the above smart phone application to allow for sorting of the search results to be prioritized for other criteria besides price.

The key feature that the projector/camera technology does have that you can’t easily do with a cell phone is the ability to project visual data onto any surface and interact with it in 3D space via hand gestures.  While there are a lot of unique uses for this, a drawback of this is that you are required to have a usable surface in front of you in the first place, and I think (for now) the LCD screen of a smart phone has the upper hand in that department.  For instance, you could be walking down a street at high noon and look at a building (like some sort of historical landmark) but not have a usable surface to project meta-data on to (although I suppose something could be read to you through an ear piece).  On a cell phone, the screen is much more visible in nearly any lighting and given further software development, all kinds of information could be overlayed onto a camera captured video stream as seen below:

The end goal in both of these technologies is pretty strait forward:  Overlay relevant information on top of the real world.  And between these two technologies, I have to say that I think smart phones still have the upper hand… for now. Even though smart phones don’t have the freedom of using hand gestures to operate your phone, it could be argued that multi-touch screens are comparable (for things like zooming on maps, photos, etc.).

What I think the real knockout advantage of a cell phone (besides the fact that an LCD screen works as a better display surface than most real life objects) is the fact that information is presented to you in a more private, personal fashion.  If you were to have personal information projected out, anybody nearby could eavesdrop on whatever is being shown to you.  For example, you wouldn’t want your online bank statement to be projected on to a wall when you’re surrounded by strangers at an airport.  It’s more personal to have such things confined to a smalls screen that you have more control over.  Then again, the idea is to use a cell phone as the core processor of the system, so in the event you have to look something personal up that you don’t want projected, you would just take your phone out of your pocket and do whatever it is that you need to do.

A bold prediction is made at the very end of the first video:  That we will one day have the ability to augment digital information on reality through some kind of brain implant.  While such a wild technology is still a long ways away, it will likely occur within a couple decades time and the development of this is only the first of several steps towards a technology we once thought to be impossible.

There is probably a small number of you out there who have seen a little bit about the Google phone on the web.  You probably won’t see TV commercials for it for a little while, because they want supplies to last for a particular demographic who this phone is being targeted towards:  the geek (specifically, software developers).  I’ve been drooling over this phone and stressing out over the fact that I don’t qualify for the $179 price tag that new T-Mobile users are going to be able to take advantage of.  I, on the other hand, would have to shell out $300 for the phone.  And as much as I would love to have this phone in my hands on October 22nd, I won’t feel down about the fact that it’s not going to happen for me.  And probably won’t happen for another year (which is when my current T-Mobile upgrade contract expires and will allow me to take advantage of a contract discount offer).

So why will I not feel so sad about the fact that I won’t soon be playing with the wicked GPS enabled software, the 3 mega-pixel camera, the open-source Android Linux operating system, the Wi-Fi network capabilities and all that other jazz?  Because something better is right around the corner, and the phone I currently have (a Motorola K1 KRZR) suits my needs quite nicely for now.  I can browse the web with it, send and receive e-mail, look up directions with Google Maps, and a few other neat things.  Though it’s all through a tiny screen using slow typing T9 to enter web addresses that aren’t in any dictionary… you know how much of a pain in the ass that is?  Still, it gets me by and is still classy looking (anything shiny is classy to me).

Speaking of Motorola, I’ve learned that they are currently headhunting for 350 new employees to focus exclusively on developing Android Linux capable phones.  LG and Samsung have made similar announcements of intentions to have Android phones on the market by Q3 of next year, which means we’re going to have a ape shit throwing storm of competition that will result in insane price drops.  Remember when Motorola came out with their first RAZR which debuted at $300, and less than a year later it was considered one of the cheapest pieces of crap for sale on eBay?  I don’t think the G1 will suffer than kind of rapid obsolescence, but it will certainly be outpaced with newer phones that run faster.  Hence, I can’t wait to see what the G2 will have in store (hopefully with an actual USB port and not that proprietary HTC ExtUSB crap).

It’s hard to say just how long I’ve been waiting for this phone to come out.  Scheduled to be on sale just in time for the holidays (can’t we agree that Halloween is twice as fun as Christmas?), this phone is dead set on absolutely killing the iPhone.  I mean, just look at it!  It’s got a freaking keyboard (read: “Tactile Response” you iPhone suckers)!!  What’s even better is that IT RUNS ANDROID LINUX!  An open-source cell phone?  Get outta here!!  And it’s only going to cost $179?  You may proceed to salivate.

Now I could try and write up a bunch of original content describing all of the super cool features this phone will carry with it right out of the box, but other websites have already done this.  Why waste my time?  So for starts, check out this Gizmodo article: Android’s 10 most exciting apps.  With this being an open-source platform, there is no telling how many more cool FREE applications will be developed after the phone hits shelves.  You can pre-order it right now at T-Mobile.com.

There will be a few minor drawbacks about this device.  For starts, it’s vendor locked with T-Mobile.  And at the moment, not all of T-Mobile’s coverage areas provide 3G Internet speeds (3G coverage maps are available on T-Mobile’s website so you can check and see for yourself).  They are also planing on limiting your download speeds after you’ve sucked up a whole gigabyte of data per month (do you really need to download a whole gigabyte of data while you’re away from your computer?).  This will likely change in the future as more users join T-Mobile and provide them with the extra funds needed to expand their networks and relax bandwidth limitations. (Update: T-mobile has killed the bandwidth limit).

Any further complaints you see about it on the net are likely being generated by jealous iPhone customers who are stuck on an expensive contract with AT&T (this much seems obvious).  But if you’re willing to spend time arm wrestling with AT&T, there is a way to cancel your contract without paying the Early Termination Fee.  You can watch an informative video about doing this here.
