strengths and weaknesses touchcsreen

Device that utilizes the touchscreen will provide convenience and speed of access for its users. We do not have to bother to look for keys on the keyboard / keypad in executing a command. Users who are used, will be optimal access the menus of the most frequently used so that the whole process will be faster. Some examples of the application to the notebook / PC or mobile phone, top-level menus will be more accessible. Notebook type Tablet PC or touchscreen display on the ATM / vending machine / kiosk is very helpful in this regard. Menu is structured so that users do not need much thinking, directly touching the screen and the command will be executed. Another example, device to find out the inventory at the warehouse or the condition of goods on shelves in the supermarket will be faster and easier when using the touchscreen. The latest technology even allows us to write with a finger or stylus, and translated as it is. This is often referred to the ability of Handwriting Recognition (handwriting recognition / picture hand). Apple products like the iPod and the touchpad on the MacBook Air can actually recognize touch on several points at once (multi-touch) without any problems. For example, zooming the photo / drawing on the iPhone can be done by moving two fingers at once.


Even so, there are some disadvantages that arise. If we want to give complex commands such as typing a sentence on the screen, sometimes there is an error that caused the software not able to translate what we input about. Also on the old touchscreen technology, touch together at several points at once will confuse the software in memahaminya.Teknologi touchscreen also will donate an additional cost on these devices. Notebook or HP that uses this technology will be more expensive with the device without a touchscreen, although its functions the same. So that should be considered at the time of purchase, whether we really need these technologies or not.

Touchscreen technology requires special care, where the screen should always be maintained clean to the touch (input) can be translated correctly. For those who like careless in using the device, you should consider the selection of this technology. If damaged, would be futile expensive price we pay at the device. Currently touchscreen technology is ideal to use on devices that require simple interaction and the user wants to make quick and accurate. But if the interaction that we will do quite complex, perhaps the keypad / keyboard combination mouse / pointer is still the best option. Hopefully in its development, the more expensive touchscreen technology, smart and accurate in understanding the inputs, so that the fore more and more devices that can be utilized with the help of these technologies
