Portable terminal capable of sensing proximity touch and method for controlling screen in the same

摘要

A portable terminal for sensing a touch input, including a direct touch input and a proximity touch input, includes a touch screen configured to receive the touch input via a touching object and responsively displaying at least a first portion of a page and a controller configured to recognize the direct touch input when the touching object contacts the touch screen and recognize the proximity touch input when the touching object is located within a threshold distance relative to the touch screen for a period of time, the proximity touch input being effective as long as the touching object remains within the threshold distance, wherein in response to the proximity touch input, a size of the displayed page is changed from a first size to a second size, or a second portion of the page is displayed on the touch screen, the second portion being different from the first portion.

1. A portable terminal for sensing a touch input comprising a direct touch input and a proximity touch input, the terminal comprising:
a touch screen configured to display at least a first portion of a page and to receive the proximity touch input via a touching object; and a controller configured to recognize the proximity touch input when the touching object is located within a threshold distance relative to the touch screen for a threshold period of time, wherein: a size of the displayed page is changed from a first size to a second size in response to the proximity touch input; and the touch screen displays at least one control window in response to the proximity touch input, the at least one control window being configured to receive a control input for at least one of:
changing the size of the displayed page;orturning the displayed page from a current page to a next or previous page, wherein the control input is received when the touching object is located within the threshold distance, wherein the at least one control window includes a scroll box indicating a portion of the page currently displayed on the touch screen, and the scroll box is configured to move in a direction of movement of the touching object relative to the touch screen, and wherein the second size of the displayed page is adjustable according to a distance between the touching object and the touch screen while the touching object is located within the threshold distance, and the second size of the displayed page is displayed while the touching object is located within the threshold distance and the first size of the displayed page is redisplayed when the touching object is no longer located within the threshold distance relative to the touch screen.
