1Q:
Ans:
HoloLens truly shines is in its vast potential for real-world use.
Here are just a few examples of real-world applications that could make
HoloLens the next must-have piece of technology.
1. Remote Instruction
Microsoft HoloLens can be taken on getting step-by-step instructions on things
like home repair from an expert. Visual diagrams would actually show up in space around the user indicating
exactly what you need to do next. This application could even extend to the
battlefield, where detailed medical instructions could be given to untrained
personnel in the midst of combat.This level of illustrated instruction could make getting the support you need
much easier, and could even mean the beginning of a new industry of remote
consulting experts.
2. 3D Computer-Aided Design using HoloLens:
Using the HoloLens to construct and design new products could be an important
commercial use of the device, especially in the age of bring your own device
(BYOD) policies in the workplace. All you need to do is send the design to a
3D printer, and your holographic model goes from concept to reality.
3. Gamification of Tasks:
The HoloLens has the potential to turn such tasks into a game. Think how much
more fun you’ll have throwing jabs and hooks at a punching bag when your
HoloLens is superimposing a boxer (or threatening mugger) over the bag. Or,
imagine getting on your treadmill and replacing the world around you with
interesting, interactive, scrolling scenery as you jog. By turning monotonous
tasks into a game, HoloLens could make life much more exciting and help you
build healthy, productive habits.
4. Gaming
Gaming is another potential use that was shown off in the introductory video from
Microsoft and the possibilities of using the HoloLens for gaming are fascinating. Several
journalists were able to get a hands-on look at how this would work during the
product’s launch event, and although the demo was rather basic, a fully immersive
gaming experience is something gamers have been clamoring for for quite some
time. Imagine playing a game like Minecraft using holographic models in your
living room. HoloLens promises to make that happen.
2Q:What is the difference between the Oculus
Ans:
We all know that Oculus Rift comes under Virtual Reality (VR) - it tricks your eyes into thinking you\'re somewhere else. On the other hand HoloLens is augmented reality(AR) and AR headset is content with keeping you in the real world, just with added holographic goodness.
Augmented Reality (AR) is an extra dimension over VR since it can also show the real world around you with graphics overlayed. However, AR can also totally immerse you just like VR by simply showing pixels everywhere, with no transparency to the real world. But as we know, pure VR applications are rather limited to games and simulation in a fixed setting (with limited furniture...)
We\'ve had the rare chance of trying out both the HoloLens development kit and Oculus VR\'s newest Crescent Bay headset. These aren\'t the final retail versions, but here\'s how they compare currently.
Tech specs: Oculus has feature of 3D positional audio that will tie in well to the Rift\'s excellent stereoscopic 3D visuals. Rift will rely on an external camera for positional head tracking, which Microsoft\'s HoloLens will not use. And because the Oculus Rift obstructs your view of the \"outside world,\" Oculus maintains that the Rift is intended for seated experiences at the moment.
This isn\'t the case with HoloLens, however. Because you can see the virtual along with the real, Microsoft is fine with you walking around with the headset on. Microsoft says that the final version will be wireless. Unlike the Oculus Rift, which needs to be plugged into a PC, the HoloLens will be a self- contained computer running Windows 10 with its own CPU, GPU, and a new holographic processing unit (HPU) to tie everything together. HoloLens does have some similarities to the Oculus Rift, however-it will support stereoscopic 3D and have speakers that provide positional audio.Other HoloLens features include an integrated depth sensor, finger-swiping gesture support, and a built-in mic. Some of that could be coming to the Rift as well, with Oculus recently acquiring camera/ hand tracking firm Nimble VR.
3Q:
Ans: The type of technologies like Hololens and Oculus Rift both the technologies puts us in Virtual reality. Moreover its improves the students multi dimensional views and ideas in the form of skills
Keep in mind that Microsoft isn\'t claiming the HoloLens headset to be a VR headset, nor is it a set of images and text layered into your field of vision through glasses, like the now-discontinued Google Glass experiment. Instead, it\'s a bit of a fusion.
Rather than waiting for us to have all sorts of new equipment built into our existing world (desks, countertops, walls, and refrigerators), the HoloLens headset overlays its VR display over existing walls, furniture, and so on; thus, we can interact with our environments (real environments, not virtual ones) using virtual elements. It\'s a mixed reality, a blending of your digital world with your real world using 3Dobjects that show up as floating images.
The gaming usage for the headset are obvious. It seems a natural next step from the Xbox and the hands-free Kinect. The consumer usage is obvious as well, because you can use the headset to watch TV (on walls without a TV hanging on them) or to play games with 3D building blocks.
From an educational perspective, the usage is clear because students can step into scenes in history and see lifelike characters -- they almost literally could see themselves at the Alamo.
The enterprise use for such a device isn\'t so obvious. But here are some to consider:
Used tastefully, the HoloLens could transform our world into a Second Life-like virtual space that, although it may have a cartoonish feel at first, would over time develop into a more sophisticated blend of real and virtual life.
4Q: Privacy concerns are one of the factors that prompted google to delay a full release of the google glass. Security and privacy implications of releasing a product like the HoloLens?
Ans:
Privacy Issues
The truth is that the first Google demo showed a device that is far more advanced than what has been released so far. Google Glass is only able to capture 10-second videos. You\'d have to press a button if you want to record for a longer period of time. Furthermore, the longer you record the faster you run out of battery, so it is highly unlikely that people will have it on while they are just casually strolling down the street.
For all intents and purposes, Google Glass is just a wearable Internet browser. It can also record videos and images, but it is not true that any picture you take gets uploaded immediately. It\'s mainly about getting news, email and other information updates much faster. Unfortunately, there are plans to give Google Glass face recognition capabilities, and when that happens we can expect a more intense public outcry over privacy issues.
HoloLens Effects and Security Concerns
Microsoft\'s recently announced futuristic holographic headset may pose a health risk to users, according to the CEO of Magic Leap, a secretive augmented-reality startup and newfound rival to Microsoft in the burgeoning AR space. Microsoft\'s HoloLens uses an input system that does not fully replicate the physical connections between our eyes and our brains, possibly resulting in permanent effects on your brain.
Yet there is a dispute whether Microsoft\'s HoloLens is functioning the same as Magic Leap\'s purported technology. Magic Leap has refused to show off its device, and neither company has fully expressed how its devices generate 3D images -- be it through light blasted directly on to your eyes, a visor with projector-like technique or a full display in an enclosed headset.
5Q:
Ans:
Both could take a decade before virtual reality and Augmented reality headsets become cheap and portable enough to replace smartphones as the tech industry’s dominant computing platform.They\'re both new technologies, cutting edge in fact, both currently involve dorky hardware and are the subject of fascination to the world\'s most influential people in tech.But the advent of AR or VR could lead us down very different paths in entertainment, gaming, communication and industry.
Microsoft\'s HoloLens has been hogging the headlines the past few months but the augmented reality tech that the industry is going nuts over is Magic Leap. The company\'s CEO Rony Abovitz is a critic of VR as the way forward in entertainment and gamin, going so far as to call it dangerous.Google Glass is underwhelming and didn\'t live up to the hype. HoloLens is impressive but has field of vision problems at this early stage. And no-one has built AR technology into smartglasses we\'d actually wear.
AR will eventually be neatly tucked into the sides of your sports sunnies, though, VR is always going to have to enclose your eyes and ears with lenses, displays and headphones to work.
AR glasses will cause etiquette problems as they \'disappear\' whereas VR will go the other way with us very clearly \'plugging in\' to a virtual world for a session. With pass-through cameras there could even be some kind of hybrid wearable that offers both.
In general, AR specs are lighter and more comfortable than VR headsets and they are more likely to be wireless and can be sustained for more than 10 to 20 years..
