Augmented Reality-The Tech of Future

Leave a Comment
Augmented reality is a direct or indirect view of a physical surrounding whose elements are augmented by computer-generated sensory input. These sensory inputs may be either sound video or any data. AR can be associated to a broader concept called mediated reality. In Mediated reality a view of reality is modified by a computer. As an outcome, the technology operates by enhancing one’s current perception of reality. By contrast, virtual reality substitutes the real world with an assumed one. 

Augmented Reality

Augmentation is conventionally in real-time context with environmental elements, such as sports scores on TV during a match. With the help of advanced AR technology the data about the surrounding real world of the user becomes interactive and digitally manipulable. Artificial information about the environment and its objects can be overlaid on the real world.
Research explores the application of computer-generated imagery in live-video streams as a way to enhance the sensing of the real world. AR technology includes head-mounted displays and virtual retinal displays for visualisation purposes, and construction of controlled environments containing sensors and actuators.
Augmented Reality is considered an extension of Virtual Reality. Virtual Reality is a virtual space in which players immerse themselves into that space and exceed the bounds of physical reality. In virtual reality, time, physical laws and substantial properties may no more be thought of as true, in contrast to the real-world environment.



 
An important step of AR systems is how realistically they incorporate augmentations with the real world. The software must deduce real world coordinates independent from the camera images. That process is called image registration. Image registration uses several methods of computer vision, mostly related to video tracking. Many computer vision methods of augmented reality are inherited from visual odometry.

IPhone 4S Siri vs Samsung Galaxy S3

iPhone 4S Siri vs Samsung Galaxy S3

http://static.applife.vn/2012/05/iPhone-4S-VS-Samsung-Galaxy-S3.jpg

As you look above the screen of the iPhone is very small when compared next to the Samsung Galaxy S3. The iPhone may have it’s ‘Retina Display’, but the high resolution of the SGS3 spread over 4.8inches is even more lovely to look at. Apple should understand that big screens are what the people want now. 

ABOUT CAMERA:

        While the camera in the SGS3 may not appear to be much better than the iPhone 4S’ camera megapixel wise  there are a few features thrown in with it that certainly make it a few steps better. The first is Burst Shot . The phone captures images at a rate of 3.3/second and then chooses the best picture of a set for you. The second is the Zero Shutter lag feature quick snaps! The last, and my personal favorite, is the ability to identify people within your photos and be able to easily send them a copy. It’s a great idea, and sharing is something that the Samsung has baked into every aspect of what is contained within the S3.
     But the camera on the SGS3 takes 8 to 24 shots at the same time.so,we can take pictures easily and we
can select the best pictures from that 8 to 24 shots and we can save it up.so i assure that you wont miss
the memorable moments and the best pictures too.
    Overall finally, the i phone 4s- the King of all Phones looks better than the Samsung galaxy s3 in
camera.
              

 

iPhone 4S Siri vs Samsung Galaxy S3 s voice:

Apple's siri, introduced as the big new feature in the i phone, is facing its biggest competitor to date in Samsung's S voice an extremely similar voice-activated mobile assistant that will make its retail debut with the Galaxy s3early next week. In anticipation of that time, I've brought the two together for a side-by-side comparison to determine which performs better at the daily tasks one might wish to entrust to a robot-voiced virtual assistant.


The first thing to say is that neither Siri nor S Voice is particularly good. Both demand that you enunciate studiously if you care to have your query recognized, and even then some hilarious misinterpretations can and do occur. That's a big stumbling block for any piece of software that aims to streamline your user experience with a smartphone -if you have to repeat or correct yourself, you might as well use more conventional means to achieve your goal. Similarly, both Siri and S Voice have a tendency to rely on external search engines for their results, sometimes integrating them in stub form within the app and sometimes throwing you out to a Google search. S Voice does the latter quite a bit more often than Siri does.
 In terms of speed, Siri has a distinct advantage over S Voice. It consistently provides an answer ahead of its Samsung competitor. On the other hand, S Voice can actually perform geographical searches whereas Siri seems to think everything I search for is within the UK and refuses to try and help with locational queries. Siri is also a lot more vocal than Samsung's application. The majority of queries sent to the iPhone are greeted with an aural affirmation of some sort, whereas S Voice tends to provide results quietly and also includes the option to turn off audio responses altogether. Which of the two approaches you prefer will be a matter of personal preference.
 Siri is faster, S Voice can do more, but neither is really good enough.

The Future Of Voice Recognition

The thought of holding a conversation with a computer seemed pure science fiction .You can ask a computer to "open the doors" but that was only in movies. But things are changing quickly. A increasing number of people now talk to their mobile for directions, or find information on the Web.

We are at a changeover degree where voice and natural-language understanding are suddenly at the cutting edge. Speech recognition is really going to upend the prevailing computer interface. Progress has come about due to steady progress in the technologies needed to help machines understand human speech. Advanced voice technology is already commonplace in call centres, where it lets users navigate through menus and helps identify customers who should be turned over  to a real customer service rep .The rapid rise of powerful mobile devices is making voice interfaces even more useful and distributive. 

The most obvious example of a voice interface is Siri, the voice-activated personal assistant that comes with the latest iPhone. While these interfaces still have significant limitations , we are inching closer to machine interfaces we can actually talk to. 





Oral communication is ideally suited to mobile computing partly because users have their hands and eyes occupied—but also because a single spoken command can achieve tasks that would normally require a large number of swipes and presses. 

Inspired by the success of voice recognition software on mobile phones, companies hope to put its voice communication interfaces in many more places, most notably the television and the automobile. Both are popular and good for innovation.

To find a show on TV, viewers presently have to navigate inconvenient menus using a remote that was never designed for text queries. Products that were supposed to make finding a show easier, such as Google TV, have proved too complex for people who just want to relax for an evening's entertainment.
 
Man Flips Tv Channels With Voice

Apple is rumored to be developing its own television, and it's speculated that Siri will be its controller. The idea has been obtained from the biography of Steve Jobs, in which Jobs claimed that he had finally figured out the TV interface.

Meanwhile, the Sync entertainment system in Ford automobiles already lets drivers pull up directions, weather information, and songs. Approximately four million Ford cars on the road have Sync with voice recognition.

One reason voice interfaces have become popular on smart phones is that users speak directly into the device's microphone. To assure that the system works well in televisions and cars, where there is more background noise, the company is experimenting with array microphones and noise-cancelling technology.

Now, maybe in the near future our devices may actually be able to understand what we speak. Next time you get frustrated with your computer don’t curse it.........maybe it will curse back.
