Description

mobile device

technical field

The invention relates to a mobile device, and in particular to a mobile device in which keys are divided into a symbol marking area and a non-symbol marking area.

Background technique

The touch screen is an inductive screen that can directly operate the operation interface elements displayed on the screen (such as a virtual keyboard, function images or scroll bars). Due to the characteristics of easy operation of the touch screen, the industry has applied the touch screen to many mobile devices, such as personal digital assistant (PDA) mobile phones, to satisfy consumers' preferences and demands.

However, taking the touch screen of a personal digital assistant mobile phone currently on the market as an example, in the virtual keyboard displayed on the touch screen, the symbol of each key is usually located at the center of the key. In this case, when the user wants to press a key of the virtual keyboard, the symbol of the key to be pressed is often covered, and it is impossible to confirm whether the key actually pressed is correct. In this way, when the user presses a button, he often touches other buttons by mistake, which causes inconvenience in operation.

In addition, when some mobile phones (such as iPhone) press a button with a finger, a small button pops up above the button to show which button the user is currently pressing. However, this button operation method is still not very intuitive, and it will also make the user feel that it is not easy to watch.

Contents of the invention

The present invention relates to a mobile device, which divides each button on the touch screen into a symbol marking area and a non-symbol marking area, and when the user presses on the non-symbol marking area, the symbols marked in the symbol marking area can be viewed , so as to know whether the pressed button is correct, so as not to touch other buttons by mistake.

According to a first aspect of the present invention, a mobile device including a touch screen is provided. The touch screen is used to display a keyboard. The keyboard has a plurality of keys. Each button is defined by a first side and a second side perpendicular to each other, and the length of the first side is greater than that of the second side. Each button is divided into a symbol marking area and a non-symbol marking area by a dividing line substantially parallel to the second side. The symbol marking area is used for marking a symbol. The non-symbol marking area is used to provide a user to press to activate the key, wherein when the symbol marking area is pressed, the key cannot be activated.

Detailed ways

Please refer to FIG. 1 and FIG. 2A at the same time. FIG. 1 shows a schematic diagram of a mobile device according to a preferred embodiment of the present invention, and FIG. 2A shows a schematic diagram of a user pressing a button of the mobile device in FIG. 1 . The mobile device 100 is, for example, a personal digital assistant (PDA) or a personal digital assistant mobile phone, and includes a touch screen 110 for displaying a keyboard 120 . The keyboard 120 is, for example, a QWERTY standard keyboard or a numeric standard keyboard, and has a plurality of keys 130 . Here, the button 130 marked as "i" drawn in FIG. 2A is taken as an example for illustration.

As shown in FIG. 2A , the button 130 is defined by a first side 132 and a second side 134 perpendicular to each other, and the length of the first side 132 is greater than the length of the second side 134 . The button 130 is divided into a symbol marking area 138 and a non-symbol marking area 140 by a distinguishing line 136 substantially parallel to the second side 134, wherein the distinguishing line 136 can be a straight line, an arc line, or any other pattern. The lines that divide the button 130 into a symbol marking area 138 and a non-symbol marking area 140 are not limited here. The symbol marking area 138 is used to mark a symbol 142, such as the letter "i". The non-symbol marking area 140 is used to provide a user to press to activate the button 130 .

In this way, when the user presses the key 130 marked with the letter “i” on the keyboard 120 , the user's finger actually presses the non-symbol marking area 140 . Therefore, the user can know whether the pressed key is correct by looking at the symbol 142 marked in the symbol marking area 138 while pressing the key 130 marked with the letter "i", without touching other keys by mistake, such as Touch the key marked with the letter "o" or the key marked with the letter "k" on the keyboard 120 . In this way, the correct rate of pressing the button 130 by the user is increased and the ease of operation is improved.

In this embodiment, each key 130 of the keyboard 120 is described as a rectangle as an example, the first side 132 is a long side of the rectangle, and the second side 134 is a short side of the rectangle, as shown in FIG. 2A . However, the shape of each key is not limited thereto. In other embodiments, each key of the keyboard can be designed as an ellipse, other regular polygons or irregular polygons according to actual application conditions. As shown in FIG. 2B , it shows a schematic diagram of another example of an oval key. When the button 130 is elliptical, a long axis A of the ellipse is parallel to the first side 132 , and a short axis B of the ellipse is parallel to the second side 134 . In addition, in the present embodiment, although the button 130 is described by taking the symbol 142 as the letter "i" as an example, it is not intended to limit the present invention. In other embodiments, the symbol 142 of the button 130 can be other letters, a pattern or a number.

The operating longitudinal direction of the mobile device 100 is the direction formed by the user and the mobile device 100 when the user holds the mobile device 100 . As shown in FIG. 1 , when the user holds the mobile device 100 , the longitudinal direction of the mobile device 100 is the Y direction. In this embodiment, the first side 132 of each key 130 of the keyboard 120 is parallel to the longitudinal direction (Y direction) of the mobile device 100, and the symbol labeling area 138 of each key 130 is located above the non-symbol labeling area 140 . Therefore, when the user presses the key 130 , the symbol 142 marked in the symbol marking area 138 can be easily observed.

In order to enable the user to easily observe the symbol 142 indicated by the symbol marking area 138 when pressing the key 130 without touching other keys by mistake, the area of the non-symbol marking area 140 of the key 130 is such that when the user presses When the non-symbol marking area 140 of the key 130 is pressed, the symbol 142 on the symbol marking area 138 is not covered. For example, the ratio of the area of the symbol marking area 138 to the area of the non-symbol marking area 140 of the key 130 is preferably about 1:1. At the same time, the symmetry of the areas of the symbol marking area 138 and the non-symbol marking area 140 of the key 130 can also achieve the aesthetics of the keyboard 120 .

In addition, if the area of the non-symbol marking area 140 of the button 130 is too small, the user may easily touch other buttons by mistake when pressing the button 130 , causing inconvenience in use. Therefore, the area size of the non-symbol marking area 140 of the key 130 relative to the user's finger is such that when the user presses the key 130 with the finger, the adjacent keys around the key 130 marked as the letter "i" are as marked as letters. The "o" button or the button marked with the letter "k" is not triggered simultaneously. In addition, if the length of the first side 132 of the button 130 is too short relative to the length of the second side 134, the symbol labeling area 138 and the non-symbol labeling area 140 configured under the situation of the limited size of the button 130 are relatively too small, so that the use of It is still quite easy to accidentally touch other buttons when pressing the button 130, which causes inconvenience in use. Therefore, as shown in FIG. 2A , the length of the first side 132 of the key 130 is preferably about twice the length of the second side 134 .

When the user presses the button 130 with his finger, usually the touch screen 110 is under the fingertip instead of the fingertip, so it is quite easy to press the button below the button to be pressed and cause an accidental touch. Therefore, in this embodiment, when the symbol marking area 138 is pressed, the corresponding button 130 will not be triggered. In this way, when the user presses the key 130 marked with the letter "i", even if the finger accidentally touches the symbol area of the key marked with the letter "j" or the symbol area of the key marked with the letter "k", , nor will the key marked with the letter "j" or the key marked with the letter "k" be activated. However, the present invention is not limited thereto, and in other embodiments, when the symbol marking area is pressed, the corresponding key may also be triggered.

In this embodiment, the symbol labeling area 138 of each key 130 is located above the non-symbol labeling area 140 for illustration, but the positions of the symbol labeling area 138 and the non-symbol labeling area 140 are not limited thereto. Please refer to FIG. 3 , which shows a schematic diagram of a mobile device in which the symbol labeling area of each key is located on the right side of the non-symbol labeling area. The operating longitudinal direction of the mobile device 200 is the direction formed by the user and the mobile device 200 when the user holds the mobile device 200 , that is, the Y direction. The second side 234 of each key 230 of the keyboard 220 is parallel to the operating longitudinal direction (Y direction) of the mobile device 200 , and the symbol marking area 238 of each key 230 is located on the right side of the non-symbol marking area 240 . In this way, when the user holds the mobile device 200 with his left hand and presses the key 230 on the keyboard 220 with his left hand, he can easily see the symbols marked on the symbol label area 238 of the key 230 .

In addition, please refer to FIG. 4 , which shows a schematic diagram of a mobile device in which the symbol label area of each key is located on the left side of the non-symbol label area. The operating longitudinal direction of the mobile device 300 is the direction formed by the user and the mobile device 300 when the user holds the mobile device 300 , that is, the Y direction. The second side 334 of each key 330 of the keyboard 320 is parallel to the operating longitudinal direction (Y direction) of the mobile device 300 , and the symbol marking area 338 of each key 330 is located on the left side of the non-symbol marking area 340 . In this way, when the user holds the mobile device 300 with his right hand and presses the key 330 on the keyboard 320 with his right hand, he can easily see the symbols marked on the symbol marking area 338 of the key 330 .

In addition, please refer to FIG. 5 , which shows a schematic diagram of a mobile device in which the symbol labeling area of some keys is located on the right side of the non-symbol labeling area and the symbol labeling area of some keys is located on the left side of the non-symbol labeling area. The keyboard 420 of the mobile device 400 includes a part of keys 430a located on the right side, such as a key marked with the letter "i", and a part of keys 430b located on the left side, such as a key marked with the letter "e".
