4.2 Current situation of operating systems used in smart phones

A Smartphone is a mobile phone built on a mobile operating system, with more advanced computing capability and connectivity than a feature phone. The first Smartphone's combined the functions of a personal digital assistant (PDA) with a mobile phone. Later models added the functionality of portable media players, low-end compact digital cameras, pocket video cameras, and GPS navigation units to form one multi-use device. Many modern Smartphone's also include high-resolution touch screens and web browsers that display standard web pages as well as mobile-optimized sites. High-speed data access is provided by Wi-Fi and Mobile Broadband.

The unprecedented growth rate Google's Android operating system has enjoyed can't last forever, and a new report suggests 2012 is the year Android's share of the global Smartphone market will peak. Market research firm IDC on Wednesday released the findings of its latest Worldwide Quarterly Mobile Phone Tracker report, and the firm predicts that cell phone shipments will reach 1.8 billion units this year compared to 1.7 billion in 2011. A sharp decline in the feature phone market will be the root cause of the stalled growth - IDC is forecasting the lowest annual growth rate since 2009 - but Smartphone shipments will offset the 10% decline expected from feature phones, growing 38.8% year-over-year to 686 million units in 2012.

While the overall Smartphone market is expected to continue growing at a healthy pace over the next five years, IDC sees 2012 as the start of a major shift. The global Smartphone market is currently dominated by Android, which will comprise an expected 61% share of the market this year, and iOS, which is forecast to claim 20.5% of the global Smartphone market in 2012.Smartphone unit shipments will continue to grow between now and 2016, but IDC believes there will be a substantial shift in momentum away from Android - which the firm believes will peak in 2012 and then begin declining - and iOS, and toward Microsoft's perpetually emerging Windows Phone platform.

During the five-year period from 2012 through 2016, Android's share of the global Smartphone market will dip from 61% to 52.9% according to IDC, Apple's iOS will slide gradually from 20.5% to 19%, and Microsoft's share of the market will balloon from 5.2% in 2012 (Windows Phone and Windows Mobile combined) to 19.2% in 2016, passing iOS to become the No.2 Smartphone platform in the world.

Here is a graphical chart of the Smartphone platforms market share in 2012: Mobile statistics (2012)

It's a mobile phone offering advanced capabilities but usually with PC-type functionality. It's an all-in-one, portable organizer, email device, phone, SMS device, camera and so much more.

Internet Access

The increased data capacity of modern cellular phone networks allows for mobile Internet access in many parts of the country. Smartphone's use Web browsers to provide access to the same webpages that standard computers can access. When purchasing a Smartphone, it is important to evaluate the quality of the phone's Web browser. A well-designed browser will allow you to browse the Internet with relative ease, while a poorly-designed browser will be difficult to use and certain Web pages may be entirely inaccessible. Many Smartphone's can connect to laptop computers to provide Internet access to the computer over a cellular data connection in a process called tethering.

Photos and Video

Most Smartphone's are equipped with a camera that allows them to capture photographs and video. Some Smartphone cameras are comparable in quality to standard digital cameras. Smartphone's can use an onboard GPS receiver to automatically mark the photo or video with the location where it was captured. They can also use their data connection to send the image or video as a multimedia message or an email or to upload it to a blog or Twitter. Most of Smartphones also feature expandable memory, allowing them to store a large number of high quality pictures or videos.

Multimedia

The large screens, powerful processors and expandable memory in most Smartphone's make them formidable portable media devices. You can store music or video files on a Smartphone and play the files back using the onboard media player. Many Smartphone's can also use their data connection to stream media from Internet media providers such as Hulu, Netflix or Pandora. Some Smartphone's include an HDMI port that allows them to connect to a HDTV or monitor to play video and audio files on the HDTV.

Advanced Sensors

To enable easier user interaction and advanced features, many smartphones have advanced sensors. Accelerometers, gyroscopes, compasses, GPS receivers and distance detectors have become common hardware in most Smartphone's. Accelerometers and gyroscopes are used in gaming and to determine which way the device is being held in order to display the correct image on the screen. Internal compasses and GPS receivers allow Smartphone's to function as versatile navigation devices, share your location with others and to provide relevant information based on your current location. Distance detectors turn the phone's touch screen and buttons off when they detect that the phone is close to your face.

Applications

David, D. (no date) provide information about Smartphone's also feature the ability to download new applications. These applications augment the features that are already available on the phone. Each Smartphone operating system has its own application store where applications, or apps, can be downloaded. Some apps are available for free while others must be purchased.

Chapter V - Future trends in features and facilities of Smartphone operating systems

5.1 Introduction

This chapter describes about future trends in features and facilities of smartphone operating systems such as; Augmented reality, PC Replacements, In-built projector, Seamless Voice Control and 3D Screens & Holograms.

5.2 Identification of future trends in features and facilities of Smartphone operating systems

As the name suggests, Smartphone's possess smarter capabilities than mobile phones, providing then additional, now essential functions like web browsing, multimedia entertainment, games etc - much like mini-computers, only small enough to fit in your pocket. Smart phones appeared in the market close to two decades ago as the alternative to mobile phones which carry the primary function to enable only two-way communication by text or calls. The smart phones of today have other extended capabilities including in-built high-quality camera lenses, mobile apps that aid productivity, video-streaming as well as connectivity that enable millions to stay connected while on the go.

5.2.1 Augmented Reality (AR)

http://media02.hongkiat.com/future-features-smart-phones//augmented-reality.jpg

The term 'augmented reality' or AR when used in the context of computer technology refers to what we perceive through our senses (usually sight) enhanced through the use of computer-generated sensory input such as sound, video, graphics and GPS data. Simply put, AR makes available more information for us users by combining computer data to what we see in real life. Using the camera on your phone, you can point it somewhere 'live' to get an information overlay of where you can find the nearest cafes or dining places.

Smartphone's being portable serve as a good platform for AR to work. You can just whip out your phone to get the latest and relevant info for what you are searching for - information which you would otherwise have to call and ask or search online before heading out of Wi-Fi coverage. Most AR apps available now utilize some form of Global Positioning System (GPS) to facilitate location searches and this feature is likely to develop further over the next couple of years because of its potential.

It seems that the primary limiting factor is the limited recognition accuracy for 'live' views when we point our camera lens at places, buildings or even people. For AR to work seamlessly and reliably, the technology for recognizing places, things or people must be of a certain standard.

5.2.2 PC Replacements

According to John B. (2010) mentioned next few years Smartphone start behaving more and more like laptops. Past June, DoCoMo (DoCoMo is a trademark of the NTT DoCoMo corporation of Japan) started offering the Toshiba T-01A in Japan, a super-fast phone that uses an advanced Qualcomm chip. With these fast processors, Smartphone's will finally run full-blown apps such as Adobe Photoshop - and not just with the limited features offered in the current Photoshop app. There are already signs of other forthcoming power apps on the horizon as well, including tools that can handle photographic effects and process large, high-res images and videos.

5.2.3 In-Built Projector

If flexible screens are not enough to compensate for the small screens on Smartphone's why not integrate a projector within? Samsung Galaxy Beam was released back in the second half of 2010. It features a built-in DLP (Digital Light Projection) WVGA projector that is able to project future-features-smart-phones/ at up to 50 inches in size at 15 lumens. What good will this do? Well, for one thing, future Smartphone's can actually be turned into interactive gaming consoles without a need for a TV screen; all you'll need is a flat surface. Instead of a physical controller, you can use your body or your voice. Similar to Kinect, a smart camera and a voice control function can capture your movements and voice commands to let you interact with objects and future-features-smart-phones/ on the projected screen.

5.2.4 Seamless Voice Control

Voice control has been receiving much attention since Apple OS feature call "Siri" made headline. Voice control has existed in many earlier mobile phones even though the voice recognition function was crude at best. Research has been made to advance the development of voice control, but it has proved to be a paramount task.

Apple Siri might have signaled a breakthrough to the way voice control and recognition programming ought to be made. Instead of recognizing commands via sound waves like most voice-recognition systems, Siri interprets diction and syntax in a similar fashion to how we recognize speech. Such Natural Language User Interfaces prove to be more effective and accurate.

The interest with voice control for computers and especially Smartphone's has always been there since the pioneer MIT research, "Put That There" studied different ways to communicate with computers in 1980. With the newly improved voice recognition app, Siri, as well as the greater capabilities of Smartphone's in the years to come, seamless voice control seems to be a viable goal. That, combined with gestures may bring interactivity to a new level for Smartphone's and their users.

5.2.5 3D Screens & Holograms

Smartphone's may have already reached the peak for their screen resolution with Apple's 'Retina Display', which actually provides a resolution that is sharper than what the human eye can perceive. Yet, even then, we still want more. Mobile companies are now moving from 2D future-features-smart-phones to 3D future-features-smart-phones/ for the Smartphone screen. At present, we have a couple of 3D Smartphone's in the market, such as the LG Optimus 3D, the Motorola MT810 as well as the very first Samsung AMOLED 3D.

Next path could possibly be holographic projections. In essence, holographic projections will mean a combination of 3D future-features-smart-phones/ and projections from the Smartphone. According to Mobiledia Network, Master Image 3D had previously showcased their ongoing development on a projection system that allows Smartphone's to display 3D holograms at the annual Mobile World Congress last February. If you want to talk about the potential of holographic projections in Smartphone's, it's great. 3D displays can be integrated with elements of movements when it comes to user interactions with the phone. For example, resize photos by using hands to 'pull' or 'compress' the holographic photos that appear in front, move objects by 'grabbing' them from one place to another, etc.

5.3 Summary

This chapter describe about features and facilities in smartphone operating systems such as; Augmented Reality ,PC Replacement, In-built Projector, Seamless voice control, 3D Screens & holograms. Augmented Reality is the augment with the real world element using GPS data, digital voice or video. PC Replacement in name in suggest replace the computer with new technological smartphones. They are fast and produce maxim efficiency like PC. Voice activated and controlled devices are the next big thing in future on mobile operating system. Thereafter 3D screens and holography technology will introduce future smartphone operating systems and its makes easier to control UI in reality.
