DESCRIPTION
A DEVICE WITH TOUCH SCREEN Technical Field
The present invention relates to a device which has a touch screen and ensures that the point or the area touched on the touch screen are indicated by means of various visual elements and thus it is touched to the intended point or the area less accidentally.
Background of the Invention
Today, use of devices with touch screen shows a continuous increase and touch screens of the aforementioned devices can be used both as an input and output unit. T he fact that a user knows and understands where she/he exactly touches on touch screens existing in devices particularly such as smart phones, tablets is of vital importance in terms of carrying out an input process with less error.
Particularly in cases when a text entry tool, for example a text keyboard, is displayed on a touch screen; the fact that users can touch the area where the intended letter is located is a significant factor which ensures an error-free text entry by preventing wrong writing.
In the state of the art, various visual feedback methods that serve for showing the user which area is touched on the touch screen are applied in order that the said factor can be realized. In these methods and the devices wherein these methods are applied, however, the center or the area of touch is displayed only as unidimensional and uniaxial (only vertically or horizontally or as a point) or the touch center marked cannot be seen clearly because it remains under the finger of
the user or the object enabling the touch. In this case, the user cannot receive feedback strong enough for concerning where the user has touched.
Considering existing techniques it is realized that there is need for novel methods which indicate touch centers in a plurality of axes such as both vertical and horizontal in touches performed on a touch screen and which enable a user to see visual tips easily when s/he looks at an area away from the touch center, and devices wherein these methods are applied. The United States patent document no. US2008204427, an application in the state of the art, discloses a device which comprises a pressure-sensitive touch screen. In the said device; an indication which varies by intensity of pressure exerted on touch screen is provided in the touched area of the touch screen during use. The monitor provides a visual indication depending on a magnitude of a pressure registered by the touch screen. The indication is rendered as centered on the touch area and has an attribute that depends on the pressure exerted.
Summary of the Invention
An objective of the present invention is to realize a device which has a touch screen, ensures that it is touched to the intended point or the area less accidentally by determining the point or the area touched on the touch screen and indicating it through a strong feedback by means of various visual elements on touch screen as well.
