precautions while using touch screen mobile

Always try to use the stylus for prolonged operations. The finger prints and sweat will reduce the visibility of screen and which require frequent cleaning. A touchscreen is an electronic visual display that the user can control through simple or multi touch gestures by touching the screen with a special stylus/pen and or one or more fingers. Some touchscreens use an ordinary or specially coated gloves to work while others use a special stylus/pen only. The user can use the touchscreen to react to what is displayed and to control how it is displayed (for example by zooming the text size).

TheFinger and included S Pencan be used to easily select items or perform functions. So tap your finger to perform various action and controls. Actions using the S Pen with the button pressed provide additional conveniences, such as screen capture and many more. Pull out the S Pen from the slot to use it.

To avoid damaging the touch screen, do not tap it with anything sharp or apply excessive pressure to it with your fingertips. The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or any other intermediate device (other than a stylus, which is optional for most modern touchscreens).

While there have been ample studies showing that there may be side effects to cell phone usage, there have been many studies refuting the health impacts, causing a large level ofuncertaintyand misunderstanding. Its human nature to keep using something that works for us unless proven hazardous, so this uncertainty has worked in favor of continued, increased use of cell phones. Understandably so too

Cell phones communicate using signals in the microwave spectrum. The invisible stream of RF (radio frequency) signals penetrate our bodies when the device is held close, and as well as the long term potential for cancer, there is also the potential to impact cognitive memory functions and to cause disorientation and dizziness. This article explains how to take precautions when using your cell phone.

The touchscreen enables the user to interact directly with what is displayed, rather than using amouse,touchpad, or any other intermediate device (other than a stylus, which is optional for most modern touchscreens). The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are found in the medical field and in heavy industry, as well as for automated teller machines (ATMs), and kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the displays content.

In the cell phone industry there are two major categories of touchscreen displays: capacitive touchscreens and resistive touchscreens. Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touches. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand. Examples of devices with capacitive touchscreens are the Apple iPhone and the T Mobile G1. However, some modern displays like the Nokia Lumia 1520 are designed to support ultra sensitivity that can detect touches while gloves are worn.

The sudden rise and proliferation of touch screens will undoubtedly lead to more research into the potential health risks, but for now users should be aware that their new devices are not immune from the problems that have long plagued traditional computer use and that precautions should be taken to avoid long term health risks.

Aresistivetouchscreen panel comprises several layers, the most important of which are two thin, transparent electrically resistive layers separated by a thin space. These layers face each other with a thin gap between. The top screen (the screen that is touched) has a coating on the underside surface of the screen. Just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is applied to one layer, and sensed by the other. When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point: The panel then behaves as a pair ofvoltage dividers, one axis at a time. By rapidly switching between each layer, the position of a pressure on the screen can be read.
