Pros: >low power (can be hooked up to a battery)
>small form factor
>TONS of I/O (analog, digital, USB3.0, JTAG)
>HDMI, SATA, SD card, and Mini PCIe
>You can run most of ROS on this
Cons: >Locked into nVidia's own Ubuntu OS for the Tegra, and the new version is obviously optimized for the TX1 and not the TK1
>Driver and software support isn't the best, because of ARM CPU
>2Gb of RAM is not a whole lot when you're trying to do image processing, the main point of this board.
Other Thoughts: I bought this board with running ROS in mind. I wanted a small, low power platform so that I did not need to worry a whole lot about battery size. For the most part, installing ROS on this is pretty much the same as if you were installing it on a laptop, but there are a few differences. The full version of ROS will not install on this. It has a few pieces of code that seem to look for an x86 CPU and won't execute on an ARM CPU. Instead you need to install the 'robot' version of ROS. In the case of ROS Indigo, that is: "apt-get install ros-indigo-robot python-rosinstall". This version of ROS is meant to run on the robot itself, not on a larger PC that is controlling a robot. That also means the tutorials are a separate install in this case, if you want those for debugging and testing.
As for nVidia's version of Ubuntu (Ubuntu4Tegra). Its not bad. Functions just like regular Ubuntu on any normal desktop. You just can't install some applications (sublime text was the most glaring one I noticed). Also, the last version developed specifically just for the TK1 has some bugs as far as OpenCV is concerned. Nothing that prevents it from working, but it doesn't work as a smoothly as it does in an x86 environment. The newer versions of Ubuntu4Tegra, that support 'both' the TK1 and TX1, supposedly fix this and I tried upgrading. I had to downgrade after trying the newer version. It did work, but ROS Indigo really did not like it. I was getting weird errors where it wasn't finding dependencies, or running packages - even the listener/talker demos wouldn't run. Perhaps this has been fixed by now, but I haven't tested it. I want a platform to work on, not a platform to debug.
All in all, its a good development platform, or even a maker board if you need some graphics processing.
This review is from: Corsair Gaming MM200 Mouse Mat - Standard Edition
Pros: >smooth surface
>can be rolled up for transportation
Cons: >Doesn't really replace my old gaming pad - not really an improvement.
>worried how long the top will stay on, because of previous experiences with flexible rubber mouse pads.
Other Thoughts: I've used the same rigid mouse pad for 3-4 years now. It is reversible, with two different 'slicknesses' - one on each side. Think it cost me $10 in a store, and is still the best mouse pad I've ever used.
So while the Corsair is nice, it can't replace my old pad. Perhaps I've just grown too accustomed to rigid pads, but I always feel like my mouse is digging in when I try to move it. Not in a 'this isn't a slick pad'. That is not the case. Just in that it is a soft pad, and I think I started applying pressure when I started using a rigid pad - gives me a little more control.
So for me, I can really only give 3 eggs - but this is largely because of a personal preference.
ADDITIONALLY: Pay *CLOSE* attention to who you are buying this from. At the time of me writing this review, Newegg is selling it for $16 - but they are sold out.. One of their selling partners is asking $25, and yet another is asking $55. Not knocking eggs off for this, but just pay close attention, because $25 for this mouse pad is pushing it - and $55 is WAY too much for this.
Update: This mouse pad has since replaced my old one (it wore out), and now function as my 'everyday' pad. Good, consistent tracking, and it has stood up to a year of daily use. If you're looking for a good sub-$20 pad, this, or its updated version (since there doesn't seem to be any difference), should do the trick.
This review is from: SteelSeries 69041 Sentry Gaming Eye Tracker
Pros: >Tobii drivers add some additional Windows functionality. alt-tab, then look. Or Win-tab, then look. Literally.
>Able to track where you're looking at the screen during streams
>Uses magnets to mount to your monitor
>Integrates with Windows Hello, allowing facial login and automatic logout/locking when you walk away
Cons: >Steelseries support is still one of the worst I've ever dealt with; very hit and miss.
>SteelSeries no longer provides statistics for where you are looking in game. (depreciated feature)
>vJoy software for the Tobii EyeX infite screen extension (necessary to allow 'look in game' for games like Elite:Dangerous and DayZ) Keeps your computer from falling asleep.
>Very picky about where your head is. Can't be closer than 'arms length' to it, can't be much further either.
>Uses magnets to mount to your monitor, and they only give you two (with no way, that I've found, to order replacements)
Other Thoughts: This is an interesting device, and there is a lot of potential if game developers take advantage of it. But so far they haven't, aside from a few titles. I played with it a little in DayZ (this is handled through the Tobii's software, not Steel Series'), and it was interesting being able to turn the character just by looking. But this takes a lot of getting used to. Even then, mine only seems to be half-working. Also, if you choose to use this feature, it will keep both your computer and monitor from falling asleep. No amount of command prompt powercfg commdands seem to be able to rectify this problem. The only solution I found was the uninstallation of the Tobii Eyex Infinite Screen Extension and the vJoy drivers it requires.
Also the Game Analyzer portion of Steel Series software has been depreciated by SteelSeries. They will no longer be supporting it in any way. It will not work with previously compatible titles, or any future titles. I emailed Steel Series support when I got the product a month ago, and got this: "We have sent this over to our QA department to investigate and are working on a resolution for you. Please do not be alarmed at the delay as we're doing some testing on our end. Thanks for your patience!".
One one hand, it seems I've hit an issue they haven't dealt with before. On the other, I haven't heard back, and they never asked me for any log files or additional information - so I am not sure what "testing" they are doing on their side.
So is this product worth $150-$200? Not unless you're streamer with following or a professional gamer that could use the analytical data it is supposed to provide (i.e. you make money gaming). Otherwise, it would need more developers making code to use eye tracking as a controller in a game. Even then, Tobii's software is far more polished than Steel Series' software. I suspect we'll see Tobii offer support for new games more quickly than Steel Series, and Steel Series will keep their product focused purely around professional gamers.
In the mean time, I actually am planning on trying this out as a sensor with ROS. It'll be interesting to see how that goes.
