Being A Little Agile

Being A Little Agile

It has been a while since I wrote starting up, I have been busy with my business (which is a good thing). When I started Bit Space Development I set out to learn. If I was going to start a business and fail, I would have learned about failing. If I built something that was sucessfull I would have learned how to succeed. What I didn’t anticipate was how much I would learn in such a short amount of time.

RKM MK12

The Rikomagic MK12 arrived yesterday morning. I like these devices, Rikomagic has made some interesting stuff in the past like the MK802. This device is like a tiny PC with some pretty good specs. It runs Android and is ready for your TV.

Starting Up

Starting Up

I gave another awkward speech to students at Red River College recently. This might not be awkward to most people but I’m not used to it. The topic was jumping off a cliff or doing what I did and jumping off a shit load of small hills.

The talk was for entrepreneurship students in the Business Information Technology program at RRC and is about building your network of mentors, gaining support and taking a leap of faith.

Raspberry Pi 2

Out of nowhere we all woke up to some news from the Raspberry Pi Foundation, there was a new Raspberry Pi. This new device comes only a few months after the Model B+ and uses the exact same layout of the board. They are of course competing with some other boards like the Banana Pro and the Banana Pi M2 hardware wise.

Banana Pi D1 Review

The Banana Pi D1 is probably the coolest dev board I have received lately. It comes form the Banana Pi folks but it is something all of it’s own. At first I wasn’t sure what I was getting but I was pleasantly surprised when I saw it was an open source IP camera. The device is tiny, 38mm x 38mm squared with a small camera hanging off of a ribbon cable at the top.

Banana Pro Review

So the Banana Pro arrived today. I have been reviewing Banana Pis left, right, and center lately. This Banana Pro is the successor to the Banana Pi, similar to the Banana Pi M2 but not quite the same because it is by the folks at Lemaker.. the other developers of the Banana Pi.

The Banana Pi M2

Not too long ago I reviewed the Banana Pi R1, and even before that I reviewed the Banana Pi original. These boards keep coming out and they keep getting better. The new M2 is not out yet at the time of writing this but the Banana Pi website lists it as coming soon. There are a lot of interesting new features which may make you reconsider this as opposed to another device for one of your projects.

Acer Switch 10

I have used a lot of laptops, and I have used a lot of tablets but the Acer Switch 10 is something different. The Switch is both a laptop and a tablet. It is a tablet when you want to play games and it is a laptop when you need to get some work done. The Acer Switch has a detachable keyboard which is sturdy when attached but easy to remove.

The Oculus Rift DK2

Virtual Reality is not a new technology, certainly not something that was imagined recently. The Oculus Rift was one of the first devices to actually do a good job with creating an immersive environment. The DK2 is quite an improvement from the original Oculus Rift, which was hard to do considering the first Oculus Rift was so amazing to begin with.

Virtual reality is difficult to describe to people who have not actually tried it. It is not quite like you are sitting at your desk with a box on your head (google cardboard), it is more like you have actually traveled to the virtual place. If a simulation is good enough, it can feel like you are really there. This is amplified if you are actually sitting or standing like the character in the simulation and if you are wearing a good headset to cancel the noise.

Hardware

The hardware is a lot better this time around. The resolution is now 960 X 1080 per eye, which is noticeable. There is an additional position tracking unit which tracks the Oculus Rift, and your device’s orientation.

Precise, low-latency positional tracking opens the door to entirely new interactive and gameplay opportunities. Great positional tracking is a key requirement for virtual reality; with it, the Oculus Rift can accurately map all of your real world head movements.

The DK2 uses low persistence OLED Displays. This basically eliminated the motion blur and jutter of the display, which is what makes you feel sick most of the time.

DK2 uses a low persistence OLED display to eliminate motion blur and judder, two of the biggest contributors to simulator sickness. Low persistence makes the scene appear visually stable, increasing the potential for presence.

Software

Software wise there is a lot to choose from experiment wise. Immediately I downloaded a tour of the solar system. This blew my mind away. One of my biggest dreams (not surprisingly) is to go to space one day. The experience was great, and it really sold me on virtual reality. On the Oculus Share site, there are loads of software experiments to download for Mac, Windows, and Linux.

There is also a plugin for the Unity game engine to develop games for the Oculus Rift. The SDK allows you to easily build games and simulations for the rift.

The Oculus Rift is paired with the publicly available Oculus SDK which includes source code, documentation, and samples to help you hit the ground running. The Oculus Rift and the Oculus SDK currently support Windows, Mac OS X, and Linux.

Over all developing for the rift is easier than you would expect, if you have a little game dev knowledge to begin with.

Usability

The device isn’t terrible to set up. There are a lot more cords than you would expect. The device I tried it out first on was my laptop at work, a 2013 Mac Book Pro. Setting up the Oculus on the Mac wasn’t terrible but it was difficult to get the displays configured correctly.

If you are going to use the Oculus Rift, the best configuration I have found so far is to just mirror your display, I found that sending my display to the rift as a secondary display just caused a bunch of issues including rotating the display. After all was said and done, it was super easy to download and try out different experiments.

Conclusion

Overall the device is great. The setup was a little frustrating. On Windows it was admittedly a lot easier to set up than Mac, which is fine because my work laptop isn’t really for gaming anyways haha. It is going to be interesting to see what kind of technologies are released for this in the near future. It is also going to be interesting to see what Samsung does with their Gear VR, based on the Oculus Rift.

Here are some fun pictures of us using it at the office.
