Advantages and Disadvantages of Touch Screens

When the first iPhone came out in 2007, it was a start of an era. Apple had introduced touch-screen mobile phones that were more than just phones and would take over the mobile industry within a few short years.

Now when you go out to buy yourself a new phone, you have to go for a touch screen device. Your only other viable options are perhaps a Blackberry phone or a very simple feature phone. Every other device will be dominated by a big touch screen. There are many advantages of touch screens, but there are some disadvantages, too, and these are described below.

Touchscreen in Tablets

The touch screen is taking over the computer industry. First, it made phones with keypads obsolete. Now it is hitting the computer market. PCs are in a decline and are fast being overtaken by tablets with no keyboards.

So what makes touch screens so good that devices with touch screens are simply irresistible? Read on and find out pros and cons of touchscreens.

Function Duality

The first great thing about touch screens is that they can perform dual functions; they are input devices and output devices at the same time. So when making a mobile device, you can save up a lot of space by using a touch screen. Touch screen phones usually have screens more than twice the size of older phones. Big screens means that you can see web pages, emails, photographs, videos etc comfortably without straining your eyes. In the future, touch screens may also function as solar cells and produce energy to charge the device's battery.

Not for Typing

A disadvantage of touch screens is that they are not suitable for fast typing. The touch keyboards do not give that reassuring feeling that physical keyboards provide. So if you are going to be doing a lot of typing, then touch screens are not for you.

A possible solution to this problem was presented at this year's Electronic Show in Vegas. Here a firm showed off a prototype device whose touch screen could pop up keys that bulge out of the screen so that fast typing becomes possible. This feature can be expected to be in production in the coming years.

Battery Loss

Another problem with touch screens that people face is that they consume a lot of batter y power. A Smartphone nowadays cannot be expected to last for more than a day whereas older phones could last for a week without charging. High quality screens are mainly responsible for this.

Adding touch screens also makes a device sensitive. A fall onto a hard surface could be the end for a device. On the other hand older devices were very resilient and could survive several falls.

These were advantages and disadvantages of touchscreens. Although touch screens have a few disadvantages but their pros far outweigh their cons. So we can expect them to dominate the computer and mobile phone markets in the coming years.

Are online passwords a thing of the past? Remembering a lot of different passwords can be tedious business. Most of us use multiple internet services like Facebook, Twitter, Google etc. and we have an account on every one of these sites and passwords. An average person has about 5-15 online accounts and expecting people to remember different passwords for all of them is unrealistic. Keeping one password is dangerous too as if one site is hacked, then all of your online accounts and maybe even your Credit Card information could be compromised. Most passwords are either too difficult to remember or too easy to guess. They are vulnerable to hackers too.  A security breach showed that out of 32 million passwords, 290,000 were as simple as 123456 and abcd123.

Biometric Identification

One possible solution is using fingerprints. As every individual has unique thumbprints, they can be used to identify a person and hence be used in place of passwords.

A very futuristic seeming idea is to swallow a special pill which when inside the stomach, sends out an electric signal. This electric pulse has a code in it that unlocks the account. The acid in the stomach acts like the acid in a battery and provides the power required to project the electric pulse. Although this seems promising, but there are certain problems with this technique as well. The

The idea of biometric identification has its merits too. Devices equipped with cameras and microphones can use facial or voice recognition to identify users. But the problem with this is that biometric data cannot be changed. If passwords are hacked, you may get a new password, but if hackers have access to your biometric information then you will be vulnerable forever. fingerprint identification system can be fooled. One possible way of circumventing such a security system is to make a dummy with the thumbprint of the victim imprinted on it. The thumbprint identification system will not be able to differentiate between the dummy and the actual finger and in this way security can be compromised.

Electronic Tattoo

Another possible way of getting passwords out of the way is to use an electronic tattoo. Each person has a unique tattoo which contains a code and an aerial. This setup sends a signal that can be used to login to your accounts. Many companies including Google are spending millions of dollars on research about these possible solutions to forgo passwords so it may be reasonable for you to expect to be beyond the era of passwords in a few years time.

  • If you follow a person, you are allowed to view their photos but they are not allowed to view your photos until you allow them to follow you (in case your posts are private). This is a new flare to privacy.
  • The Instagram images could be shared on Facebook, Twitter, Tumblr, Flickr and Foursquare. If shared on Facebook, the privacy setting of each of the photos from the Instagram album could be separately controlled. This feature provides the liberty of controlling and sharing.

With so many interesting and beneficial features, it is not surprising that Instagram has seen such phenomenal success. Seeing the great boom and increasing market, Facebook rightly bought the service in 2012.

Diagnosis and IT

There are many benefits of using IT in medical field. The modern IT provides many tools, aide and assistance in solving problems quickly and efficiently. Powerful computers have the ability to organize and present data in a tidy manner so that it is easy to draw conclusions from a set of raw facts. This can help medical personnel detect certain patterns of ailments in their patients which can lead to their spotting progression of diseases in a society. Doctors can also take some help from information technology in recognizing symptoms and locating the origins of the symptoms using the experiences of other doctors who have had patients with similar problems. Similarly, they can use others' experience while suggesting possible solutions to the diseases and deciding whether surgery is necessary or medications will be sufficient.

Data Management

Information Technology can also be helpful for doctors to keep track of their patients' medical history. The medical history, efficiently stored and presented, can help the doctor determine the medications that would suit the patient. It may also help him recognize if certain dangerous patterns are forming in the recurrence of a certain disease.

Most can made out of the potential of Information Technology if the medical personnel share their experiences in curing different diseases with others so that the other doctors can look up similar cases and know from the formers' experience the likely result of a certain suggested cure. But of course precautions have to be taken so that personal information of the patients is not made public. There are certain things that have to remain between the doctor and the patient. These details must not be compromised.

IT Professional in Medical Field

Doctors themselves cannot be expected to keep up with all the latest technological innovations and the new ways to share data. So it is the responsibility of the medical institutions to hire IT experts who can guide the institution into using IT efficiently and fulfill the promise of Information Technology. These IT people can collaborate with the medical staff to make sure that all the useful information is available to be used by others looking for the very same kind of information.

Information Technology has loads of opportunities and new ways to communicate and share information. Medical fields must also cash in on these prospects to the benefit of the society and the community as a whole.

Use of IT in medical field is increasing day by day and simplifying doctor's day to day work.
