Smart tools are everywhere now. Likewise many manufacturers are diving into the development of Augmented reality( learn more about augmented reality and VR here VR vs AR )Even BMW is working on something related to augmented reality, motorcycle helmets that let drivers keep tabs on their gas levels and RPMs without glancing down from the road. The helmet also features front and rear cameras.

Some rare fighter pilots have been using augmented reality built into their helmets for years to keep an eye on the plane’s gauges, monitors, and weapons systems without having to look down. Now that technology is coming to motorcycle riders, with BMW and DigiLens.

We may argue that, displaying some info on the screen doesn’t make it augmented reality, but DigiLens does manage to drop a layer over the rider’s view that enhances real world road environments.

The helmet’s functions are actuated with controls on the left handlebar (which is good, because mucking with controls on the helmet itself while riding could get a little messy). It also has a forward-facing action cam that can record your ride, and a rear-facing camera that can be used as a virtual rear-view mirror in the heads-up display. The system is powered by removable batteries that are good for a claimed five hours of life.

A quick reminder, this is kinda similar to Google glass!! And some sources says that BMW is also working on some innovative cars which use augmented reality.

All these developments, in installing new technologies in various unique tools is due to INTERNET OF THINGS, which brings various indifferent things under a common roof so called Internet. Learn more about INTERNET OF THINGS here Internet of things.

So, let me know your thoughts about this…

How we see 3D??

A stereo image is basically a 3D image. We have seen a lot of “virtual reality headsets” in 2015( Learn more about VR here, I have a bunch of articles on VR Google VR, VR vs Hologram, Best apps for Cardboard VR, How to make a cardboard VR DIY). If we look at the phones screen without the VR set, the image we see is a stereo image. The image below is a stereo image.


When we look at an object, both of our eyes looks at the same object. Two set of images are formed, one with each eye. Then our brain manipulates and merges both images to give us a 3D view.

So, now we get an idea on how we see in 3d. Then how do we see 3D video on a 2D screen??

Well.. The basic requirement to see in 3d is to have two images one for each eye. To do this on a 2d screen, we may project a stereoscopic view( the image above is a stereo image) and separate each eyes view.

This sounds great, but doesn’t work in a movie theatre with many people.

To overcome this problem, we started overlapping the image. Ok, now how those two overlapped images are separated for each eye?

Here comes the Polarised glasses. Both the overlapped images on the screen are polarized in a different way, each lens on the glasses are used to match the respective polarization. There we go, we have one image for each eye. But if we look at the image without glasses, the image looks something like this;)


This is how we experience 3D:)




Before we get into making a virtual reality headset, we should know something about, what exactly is it? “VIRTUAL REALITY” what’s that? Well.. it’s an immersive multimedia, precisely when we here to some music through headsets we actually cover our ears and listen nothing but music which is playing in that headsets, similarly when we put on vr we see multimedia everywhere we feel like we are in another world where it seems like things are happening really in front like 3d.

There are two ways to get a VR headset, 1) Buy it online and assembly; 2) Make the parts yourself with measurements specified by google on the internet.

Before we get started, let me tell you that the cost in both cases is similar and trust me this is as good as OCULUS RIFT. A real experience.

-> If you can’t wait or don’t want to miss anything on your VR. Buy it online.


I know we are not interested in reading long long paragraphs of steps, so check out the video below.

1. Download this compressed template folder from Google. You will see two design files.

2. Print one of the design files. You can print the first design file using a standard printer (and later use the design as a template to manually cut Google Cardboard from cardboard), or you can print the second design file using a laser cutter. It will print (aka cut) cardboard stock into the exact shape you need. Keep in mind that laser cutters and cardboard stock are often pricey, so it will be much easier on your wallet to go the standard printer route.


3. If you used a laser cutter, continue to the next step. The rest of you will need to follow these instructions:

The first thing you’ll need to do is to glue the template onto cardboard. Any craft or multi-purpose glue will work. Google also said you could use an extra large pizza box or buy cheap cardboard sheets from Gaylord or Kraft, available for purchase at Amazon and most art supply stores. E-flute corrugated cardboard is preferred because it’s thin. Minimum size: 8.75in (22cm) by 22in (56cm), and 0.06in (1.5mm) thickness.


The second thing you’ll need to do is to glue the light numbers (as seen on the template) onto the dark numbers. It’s like you’re doing beginner-level origami. Once that’s done, follow the template lines and cut your Google Cardboard from the cardboard sheets. An X-Acto knife, box cutter, or any pair of scissors will work. There’s no need to buy specialised craft scissors just for this project. You can also use a ruler to ensure straight cuts.


4. Now that you have your cardboard cutout, you are free to assemble Google Cardboard. Follow the red lines on your template to fold the cardboard cutout. Like magic, you will see the form of Google Cardboard emerge. But you’re not done the assembly process yet. You need to acquire some tools and materials.

5. This next part is the trickiest: you must get two lenses that have a 40mm focal distance. Google recommended Biconvex lenses because they prevent distortion around the edges. You can also use the lenses that come with the Durovis OpenDive Lens Kit. You can find these online.

6. You’re not done buying things just yet. Find and purchase one neodymium ring magnet and one ceramic disk magnet . Approximate size for both magnets: 0.75in (19mm) diameter and 0.12in (3mm) thickness. Once you’re all set, affix the ring magnet and disc magnet exactly where the template shows on your Google Cardboard.


7. You’re half-way done the assembly process. Now you need to buy two strips of regular strength adhesive-backed velcro. Again, they’re available online.
