The touch screen¡ªan electronic display that can detect the touch of a finger, stylus, or other object¡ªwas born in 1968. That year, a British inventor developed a touch-screen computer for use by air traffic controllers. The first touch-screen phone was IBM¡¯s Simon, which hit stores in 1993. But the technology did not truly take off until 2007, when Apple introduced the iPhone. Both user-friendly and futuristic, the technology had immediate appeal, and it increasingly dominates the smartphone market. ¼Õ°¡¶ôÀ̳ª ½ºÅ¸ÀÏ·¯½º ¶Ç´Â ´Ù¸¥ ¹°°ÇÀÇ Á¢ÃËÀ» °¨ÁöÇÒ ¼ö ÀÖ´Â ÀüÀÚ µð½ºÇ÷¹ÀÌÀÎ ÅÍÄ¡½ºÅ©¸°Àº 1968³â¿¡ ź»ýµÇ¾ú´Ù. ±× ÇØ, ÇÑ ¿µ±¹ÀÎ ¹ß¸í°¡°¡ Ç×°ø°üÁ¦»ç°¡ »ç¿ëÇÒ ¼ö ÀÖµµ·Ï ÅÍÄ¡½ºÅ©¸° ÄÄÇ»Å͸¦ °³¹ßÇß´Ù.

There are several types of touch screens, but only two are widely used in smartphones: resistive and capacitive. A resistive touch screen is comprised of a piece of glass coated with two thin metallic layers, which are held slightly apart. One layer is conductive of electricity, the other resistive. An electric current runs through them. When the screen is touched, the two layers make contact at that spot, changing the electric field. The phone¡¯s computer determines the location of the change and converts it into a signal that the operating system can understand. In a capacitive system, the glass panel is covered with only one metallic layer, which holds an electrical charge. (¡°Capacitance¡± is the technical term for an object¡¯s ability to store electrical energy.) Some of that charge is transferred to the user when he or she touches the screen. Using circuits at the four corners of the screen, the computer calculates the precise location of the decrease in charge and relays this information to the phone¡¯s software. ¸î Á¾·ùÀÇ ÅÍÄ¡½ºÅ©¸°ÀÌ ÀÖÁö¸¸, ´Ü µÎ Á¾·ù¸¸ÀÌ ½º¸¶Æ®Æù¿¡ ³Î¸® »ç¿ëµÇ°í Àִµ¥; Àü±âÀúÇ×¹æ½Ä°ú Àü±â¿ë·®¹æ½ÄÀÌ´Ù.

Capacitive touch screens, such as those on iPhones and Samsung¡¯s Galaxy S, are more sensitive; they require only a very quick, light touch. While this responsiveness is desirable in a way, it can be a drawback in that it is annoyingly easy to hit the wrong letter while typing on the onscreen keyboard. Resistive screens, such as those found on some popular LG and Nokia models, require a bit more pressure and are thus more accurate. Another advantage of resistive systems is that because they operate by way of physical pressure, they can detect the touch of even electrically insulated objects such as gloved fingers.

Perhaps the greatest advantage of the capacitive touch screen is that unlike its main rival, it can support multi-touch functionality. As the term suggests, multi-touch screens can respond to more than one touch at a time. More elaborate gestures, such as a four-fingered swipe to switch between two applications, have been developed for the iPad. ¾Æ¸¶µµ Àü±â¿ë·®¹æ½Ä ÅÍÄ¡½ºÅ©¸°ÀÇ °¡Àå Å« ÀåÁ¡Àº ÁÖ¿ä °æÀïÀÚ¿Í´Â ´Ù¸£°Ô ´ÙÁßÁ¢ÃË ±â´ÉÀ» Áö¿øÇÒ ¼ö ÀÖ´Ù´Â »ç½ÇÀÌ´Ù. ±× ¿ë¾î°¡ ¾Ï½ÃÇÏ´Â ¹Ù¿Í °°ÀÌ, ´ÙÁßÁ¢ÃË ½ºÅ©¸°Àº µ¿½Ã¿¡ Çϳª ÀÌ»óÀÇ Á¢ÃË¿¡ ¹ÝÀÀÇÒ ¼ö ÀÖ´Ù; ¿¹¸¦ µé¾î, »ç¿ëÀÚ°¡ µÎ ¼Õ°¡¶ôÀ¸·Î ȸéÀ» ¤°í ¼Õ°¡¶ôµéÀ» ¹ú¸²À¸·Î½á ½ºÅ©¸°À» È®´ëÇÒ ¼ö ÀÖ´Ù. µÎ ¾îÇø®ÄÉÀ̼ÇÀ» ±³È¯Çϱâ À§ÇÏ¿© ³× ¼Õ°¡¶ôÀ¸·Î Ä¡´Â °Í°ú °°Àº ´õ¿í Á¤±³ÇÑ ¸öÁþÀÌ iPad¸¦ À§ÇÏ¿© °³¹ßµÇ¾ú´Ù. While touch-screen phones are increasingly popular, not everyone has been converted. ¡á Critics of touch screens point out that buttons¡ªor ¡°tactile controls,¡± as they are often called¡ªoffer physical feedback to the user in the form of movement, something touch screens lack. ¡á The next major trend in touch screen phones appears to be haptics, a term that means perception by touch. ¡á A Japanese company recently built a prototype of a haptic smartphone, which employs vibrations to make the user feel as if he or she is actually pressing a button with each touch of the screen. ¡á ÅÍÄ¡½ºÅ©¸°ÀÌ Á¡Á¡ ´õ ´ëÁßÀûÀÌ µÇ¾î°¡Áö¸¸, ¸ðµç »ç¶÷ÀÌ ´Ù ÀüÇâÇÑ °ÍÀº ¾Æ´Ï´Ù. ¡á ÅÍÄ¡½ºÅ©¸° ºñÆÇÀÚµéÀº ¹öư¡ª¶Ç´Â ¶§¶§·Î ÁöĪµÇ´Â ¹Ù¡°Ã˰¨Á¶ÀÛ¡±¡ªÀº ¿òÁ÷ÀÓ ÇüÅ·Π»ç¿ëÀÚ¿¡°Ô ¹°¸®Àû Çǵå¹éÀ» Á¦°øÇϴµ¥, ÅÍÄ¡½ºÅ©¸°¿¡´Â ¾ø´Â °ÍÀÌ´Ù. ¡á**ÅÍÄ¡½ºÅ©¸° Àüȱâµé¿¡¼ ±× ´ÙÀ½ Áß¿äÇÑ Ãß¼¼´Â ÇÝÆ½½ºÀÎ °Í °°Àºµ¥, Ã˰¨¿¡ ÀÇÇÑ ÀνÄÀ» ÀǹÌÇÏ´Â ¿ë¾îÀÌ´Ù. ¡á ÀϺ»ÀÇ ÇÑ È¸»ç°¡ ÃÖ±Ù¿¡ ÇÝÆ½ ½º¸¶Æ®ÆùÀÇ ½ÃÁ¦Ç°À» ¸¸µé¾ú´Âµ¥, »ç¿ëÀÚ°¡ ½ºÅ©¸°¿¡ Á¢ÃËÇÒ ¶§¸¶´Ù ½ÇÁ¦·Î ¹öưÀ» ´©¸£´Â °Í °°ÀÌ ´À³¢µµ·Ï ¸¸µå´Â Áøµ¿À» äÅÃÇß´Ù. ¡á 1.
