What is a smart phone? so-called smart phones (Smartphone), refers to \function expansion, and can be achieved through the mobile communication network to access the wireless network so that the general term for a class of mobile phones. \ short, smart phones, is a computer-like can download and install software to develop the basic functions of mobile phone factionory. smart phones do? Broadly speaking,ghd hair dryer, smart phones with phone calls in addition to function, but also most of the functionality with a PDA, in charactericular, personal information management, and wireless data communications based on the browser and email functions. Smart phones supply users with enough screen size and bandwidth, which is convenient to carry, but also for software and content service providers to run a big stage, can have a lot of value-added services, such as: stocks, news, weather, traffic, commodities, application downloads,ghd price, music, picture downloads and more. 3G communication networks with the support of the development trend of smart phones, is bound to be a strengthful set of calls, text messaging, Internet access, television and entertainment as an integsized personal handheld devices. smartphone category the birth of smart phones is the Pocket PC (Pocket PC) evolved. Is not the first Pocket PC phone calls with function,ghd australia cheap, but as users of handheld computers for personal information processing function depends on improved, but not used by the phone and the PPC alsteps carry two devices, so manufacturers will Pocket PC system transplanted to the phone, so there came the concept of smart phones. Since the birth of smartphones and handheld computer-related, then it will certainly be the operating system and Pocket PC related. The current smart phone system includes Symbian, WindowsMobile the Smart Phone and Pocket PC, Palm, Linux five. But with the PC operating system, Palm and Windows CE rivalry of two strong differences in the smart phone operating system, Symbian has grabbed the initiative, Nokia basically using the Symbian operating system. Symbian: Symbian's like a combistate of Windows and Linux, have a good interface, and interface with core separation technology, low roughware requirements to support the C + +, VB, and J2ME. Compatibility well. NOKIA Symbian system is present to promote the company has been very mature. From the already by the SeriesS60, developed to S80, S90 and UIQ. Note that not all of the Symbian systems are intelligent systems, such as the earlier S40 system, not section of smart phone system. Representative models: NOKIA N73, N95, E90, N81, N70, E50, N82, N93, and so many models. Smart Phone: launched in 2001, Microsoft's smartphone operating system. Blood with earndows, so there is very strong in the desktop PC can be synchronized, superior entertainment capabilities. The disadvantage is relatively high hardware requirements, the system is often unstable due to insufficient memory. on behalf of models: Dopod 515,535,565,575,585, etc. 5X5 series; Motorola MPX200, MPX220; PocketPC: as a dedicated system for Windows CE PDA phone an extension on, WM system, can be seen the launch of Microsoft's smartphone operating system market for attention. WM system has many inherent advantages, such as a powerful built-in software, WORD, EXCEL. IE, MSN MESSENGER, OUTLOOK, MediaPlay, etc., and other similar software on the system so arduous to carry out perfection and unity. Due to hardware requisitioning so prices are high, the power consumption is still very large, and the SP systems, the stability of the relatively poor. on behalf of models: Dopod S1, P800, Amoi, Lenovo are involved. Palm: This system is very low hardware requirements, so the price can be well controlled, power consumption is also small. Palm biggest advantage is the system appeared earlier, a separate PALM handheld computer experience, so its extremely rich third-party software, business and personal information management features outstanding, and the system is very stable. demerit is less entertaining, the operation more difficult, difficult for beginners to obtain started. Representative models: Treo series of smart phones, 680,650 and so on. Linux: Linux with open source, low-cost software licenses, application development, rich human resources, etc., to facilitate the development of personal and industrial applications. Since starting too late, not too strong software foundation. on behalf of models: Motorola A780, A1200, E2, Philips 968. trend of the future evolution of smart phones first phone constantly deviate form and function, for example, from large to small in appearance, is just starting to now is very compact Mobile phone. Initially,ghd hair products, it was purely from a functional point of view of the call, send text later, and then send pictures, there are some simple multimedia applications. If there are two major trends in mobile phone, a cell phone with PDA, a PDA with a cell phone. However, many mobile phone features are not fully utilized. currently just doing simple processing of multimedia, such as MMS is simple transmission of image,ghd hair straightener price, voice dialing is simple matching fragments of sound, the so-called mobile matchs just for a simple application with very limited communications, which have more potential to go digging. One is the level and depth of processing of multimedia can do a lot of toil, such as image, fingerprint recognition, face recognition, text recognition. The words from the voice of scene can have voice recognition. Speaking from the media types, taking pictures of them just a multimedia, you can also put a lot of images, graphics, sound, FLASH and more. Therefore, the future direction of mobile phone is more intelligent and humane. Second, the mobile multimedia technology in future applications for the phone as a multimedia equipment, modeing equipment and reproduction equipment. The first recognition, for example, I saw a man is the third meeting but still could not utter his name, this is a very embarrassing thing. If I shoot his face down, and then sent to the server, which of them was the face of the database, then you can tell, I knew who he was. Technology involved there is a cell phone camera, as well as face recognition, image transmission. The second is the speech recognition can be directly reported to dial a number, look under the voice telephone entries. The third is to do text recognition, such as during an English word or sentence, I shot down to send to the database, it can tell me what I meant. Technology is involved in OCR, you can take pictures side limit translation, it is a machine translation to replace the dictionary. The fourth is content-based retrieval, the input images from a mobile phone or similar melodic shares to find the image or music, for example, I sing in karaoke OK, often do not know will sing the song. This is my recording as long as my mobile phone to sing the melody sing out, you can tell me what song. Technology involved is based on the content retrieval of images and sound can have a lot of them in the digital entertainment applications. The fifth is the video of the panorama, is captured every time we take pictures of a small breezeow, but could not make the full screen, only one to link it to a beat, and then link the image processing software, you can put this video panorama panorama shot down. Sixth alterive multimedia player, alter in the transmission method. Finally, a simple shot phone, send, MP3 and other simple functions no longer satisfy people's requisition. And people need to be more intelligent, humane, multimedia algorithms can be embedded into the chip, so the phone in the future will be more intelligent, and multimedia mobile phones and embedded technology will combine, so the future is mobile + phone Smart + Media + embedded. advance of the global smart phone market results of the study according to Norson 2005, global sales of smartphones reached 55 million, 2.6 times in 2004. Future smart phone market will continue to assert the momentum of rapid growth, the volume and the proshare in the mobile phone market will continue to increase. smart phone in the world compete in the operating system to Nokia, Sony Ericsson, Symbian camp, as the describeative took absolute advantage, in 2005, obtained using the Symbian operating system, authorized eight companies sold 28 million Symbian smart mobile phones, share of 52%. Linux on Motorola camp represented the second highest share. Linux system has the advantage of lower cost, can be tailored according to the demand for mobile phone manufacturers, Linux operating system for mobile phones in the Asian market reveals the trend by the users of all ages. In third place, Microsoft's Windows Mobile series, though with the comanner with Intel, Windows operating system, PDA phones in emerging markets grow faster, but befactor of Microsoft's operating system software and user interface for the control is too strong, mobile phone manufacturers and operators are still very cautious attitude. Summary In summary, the system uses more than five mobile phones, smart phones is that the vast majority of (but some models, although not to the use of Linux.) In addition, there are relatively small share of intelligent systems, there is not described in detail. There are some features to support mobile phone PDA, such as the HP6515 and so, strictly speaking, should be classified PDA, not smartphone. In fact, with mobile phones, the rapid development of wireless communication technology for smart phones, PDA, PPC is not very much deviateence between the obvious. With the BlackBerry, iphone, and Google's smart phone operating system developed android, smart phones are 941947107efbbdbaneful evil15b3953adaab0a7n to the updated definition. |
