Speech on smartphone
INTRODUCTION: 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 smartphones combined the functions of a personal digital assistant (PDA), including email functionality, 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 smartphones also include high-resolution touchscreens and web browsers that display standard web pages as well as mobile-optimized sites. High-speed data access is provided by Wi-Fi, mobile broadband, NFC and Bluetooth. In recent years, the rapid developments of mobile app markets and of mobile commerce have been drivers of smartphone adoption. SMARTPHONE’S HISTORY:
Devices that combined telephony and computing were conceptualized as early as 1973, and were offered for sale beginning in 1994. The term “smartphone”, however, did not appear until 1997, when Ericsson described its GS 88 “Penelope” concept as a Smart Phone. The distinction between smartphones and feature phones can be vague, and there is no official definition for what constitutes the difference between them.
One of the most significant differences is that the advanced application programming interfaces (APIs) on smartphones for running third-party application scan allow those applications to have better integration with the phone’s OS and hardware than is typical with feature phones. In comparison, feature phones more commonly run on proprietary firmware, with third-party software support through platforms such as Java ME or BREW. An additional complication is that the capabilities found in newer feature phones exceed those of older phones that had once been promoted as smartphones.
TYPES OF SMARTPHONE: TFT LCD: TFT stands for Thin Film Transistor technology. TFT LCDs are the most common type of display units used across mobile phones. TFT LCD offer better image quality and higher resolutions compared to earlier generation LCD displays but their limitation lies in narrow viewing angles and poor visibility in direct light or sunlight. IPS-LCD: IPS stands for In-Place Switching. IPS LCDs are superior to normal TFT LCD displays with wider viewing angles and lower power consumption which leads to a much improved battery life. IPS-LCDs are costlier than normal TFT LCD and hence are found only on higher end smartphones.
A higher resolution (640 x 960 pixels) version of IPS LCD is used in Apple iPhone 4 and is called Retina Display because of its brilliant picture quality. Touchscreen LCD: Touchscreen LCD displays are of two types – Resistive and Capacitive. Resistive touchscreens contain two layer of conductive material with a very small gap between them which acts as a resistance. When the resistive touchscreen is touched with finger (or stylus) the two layers meet at the point of touch thus making a circuit at the point of touch.
This information is recognized by the mobile’s processor / chip and passed on to the mobile’s OS there by triggering and event / action at the point of touch. OLED: OLED stands for Organic Light Emitting Diode and is a newer technology for displays of mobiles and monitors. In OLED technology a layer of organic material (carbon based) is sandwiched between two conducting sheets (an anode and a cathode), which in turn are sandwiched between a glass top plate (seal) and a glass bottom plate (substrate). When electric pulse is applied the two conducting sheets, electro-luminescent light is produced directly from the organic material sandwiched between. Brightness and color can vary depending on the electric pulse. Gorilla Glass: Gorilla Glass is a special alkali-aluminosilicate glass shield with exceptional damage resistance that helps protect mobile displays from scratches, drops, and bumps of everyday use. Many companies like Motorola, Samsung and Nokia are now using Gorilla Glass to make their mobile displays more durable and reliable.
ADVANTAGE OF SMARTPHONE: There are numerous advantages to having a smartphone. Increased connectivity is a major advantage of owning a smartphone or at work. These phones also integrate contact information, which makes keeping in touch with friends, family, and coworkers much easier. Smartphones also decrease the number of technological devices that professionals like businessmen and doctors need to carry. It was not that long ago that we would see businessmen carrying, a cell phone, a palm pilot, and a pager and now thanks to technological advances the excessiveness is passé.
The many applications offered for smartphones allow users to customize their phones with tools that they will use, which have a greater range than the few preloaded applications that come on traditional cell phones. These applications contribute to the better entertainment for even the times when users are waiting in line at stores.
Conclusion: The security concerns of smartphones could potentially lead to ethical issues at the workplace. When you are using smartphones to download documents from your phone, your company policy might be prohibiting company documents to outsiders, but some people might be breaking the principals by downloading the workplace information on their phone (2, 2010). You could also be breaking the company policy by using smartphones to record meeting or taking pictures (2, 2010). More and more organizations are breaking their company policy by using smartphones at workplace instead of using a personal phone provided by their company.
