The left shift button 520 can be pressed by a user's left hand while the right general character button group 610 can be pressed by a user's right hand, thereby combining the two buttons to be used. For example, the left shift button 520 may be used to select uppercase and lowercase of the alphabet. Meanwhile, the left shift button 520 may also be provided to input double consonants and double vowels among the Korean characters.
The left shift button 520 can be provided below the left general character button group 510, and spaced farthest from the opening 110 and adjacent to a circumference of the main body casing 100. Thus, a user may be least interrupted by other buttons of the left input button group 500 when inputting characters.
The numeric lock button 530 can be adjacent to the left shift button 520. The numeric lock button 530 can be provided to input numerals with buttons included in the left and right general character button groups 510 and 610.
The ‘ ̃’ button 540 and the ‘-’ button 550 are provided in a right side of the numeric lock button 530. The ‘ ̃’ button 540 and the ‘-’ button 550 are used most frequently among the special characters of the character input keyboard of a computer interface. As illustrated in a graph representing the usage frequency of the special characters in FIG. 4, the ‘ ̃’ button 540 has 46% usage frequency, followed by the ‘-’ button 550 having 13% usage frequency. Based on the result, the ‘ ̃’ button 540 and the ‘-’ button 550 which are used most frequently can be included in the left input button group 500, thereby improving user's convenience. However, the present general inventive concept is not limited thereto, and other special characters may be includes as the buttons 530, 540, and 550.

Accordingly, as the ‘@’ button 560 can be included in the left input button group 500, a user may send e-mail from the portable computer 1 without difficulty.
The right input button group 600 can be provided in the right panel 130 to be symmetrical to the left input button group 500, leaving the display part 300 therebetween. The right input button group 600 may include the right general character button group 610 which has the remaining alphabet buttons, a right shift button 620, a space button 630, a back space button 640, an enter button 650, and the Korean/English conversion button 660.
The right input button group 600 may further include ‘<’, ‘>’ and ‘?’ buttons in consideration of usage frequency and necessity.
The right general character button group 610 may include the remaining alphabet buttons that are not included in the left general character button group 510.
The right shift button 620 can be pressed by a user's right hand while the left general character button group 510 can be pressed by a user's left hand, thereby combining the two buttons to be used. As the left shift button 520 and the right shift button 620 are respectively provided in the left input button group 500 and the right input button group 600, a user may input characters by selectively pressing the shift buttons 520 and 620 in the left and right general character button groups 510 and 610.
The right shift button 620 can be provided below the right general character button group 610, i.e., can be spaced farthest from the opening 110 and adjacent to the circumference of the main body casing 100. Thus, a user may be least interrupted by other buttons of the right input button group 600 when inputting characters.
The space button 630 can be provided below the right general character button group 610, to be adjacent to the opening 110. The space button 630 can be provided to input space between characters and is most frequently used in the character input keyboard of a computer interface. The space button 630 can be included in the right input button group 600 since 60% of users press the space button 630 with their right hand. The space button 630 can be larger than other buttons to allow a user may press the space button 630 without difficulty.
The back space button 640 can serve to remove a character which is before a pointer or a cursor 800.
The enter button 650 can be provided to select an object of the display part 300 or to change paragraphs or lines to input characters. The enter button 650 can be provided below the right general character button group 610, and can be spaced farthest from the opening 110 and adjacent to the circumference of the main body casing 100. Thus, a user may be least interrupted by other buttons of the right input button group 600 when inputting characters.
Like the right shift button 620, the enter button 650 can be provided below the right general character button group 610, and can be spaced farthest from the opening 110 and adjacent to the main body casing 100.
The Korean/English conversion button 660 can be provided to convert the alphabet or Hangul, the Korean characters. The Korean/English conversion button 660 can be pressed by a user to input one of the alphabet or the Korean characters from the left and right general character button group 510 and 610. The left and right general character button groups 510 and 610 have the alphabet and the Korean characters written thereon.
However, the present general inventive concept is not limited thereto, and if the portable computer 1 includes other characters instead of Hangul, the Korean/English conversion button 660 can be provided to input one of the alphabet or the other characters. If the left and right general character button groups 510 and 610 are provided to input only the alphabet, other function buttons, such as an Alt button, may replace the Korean/English conversion button 660.
The pointer mover 700 can be provided at a first side of the left panel 120 to be spaced from the left input button group 500. The pointer mover 700 can be provided below the left input button group 500. The pointer mover 700 moves the pointer 800 displayed on the display part 300 in a predetermined direction.
The auxiliary button 800 can be provided below the right input button group 600. The auxiliary button 800 can be provided to be symmetrical to the pointer mover 700, leaving the display part 300 therebetween. Thus, a user's right hand can press the auxiliary button 800 while his/her left hand manipulates the pointer mover 700. User's both hands are positioned to be symmetrical, thereby stably supporting the main body casing 100. The auxiliary button 800 may include an auxiliary enter button 810 and a mouse clicking button 820.
The auxiliary enter button 810 may have the same function as the enter button 650. While the enter button 650 included in the right input button group 600 can be mainly used to input characters, the auxiliary enter button 810 can be used to select a predetermined object displayed on the display part 300 by moving the pointer 800 by the pointer mover 700.
The mouse clicking button 820 can be provided below the auxiliary enter button 810. The mouse clicking button 820 may include functions of left and right buttons of a conventional computer mouse. The mouse clicking button 820 can be used to select the pointer 800 and pop-up information.
A process of writing a document by the portable computer 1 according to the present general inventive concept will be described with reference to FIGS. 1 to 3.
A user faces the display part 300, and grips the lower parts of the left and right panels 120 and 130 with both hands. If the portable computer 1 is turned on, the power supply 400 supplies power to the main board 200 and the display part 300. The CPU 210 drives the operating system stored in the memory 220, and displays an image on the display part 300 through the image signal processor 230.
If the operating system based, on a graphic user interface (GUI), is initially driven, the user confirms it through the display part 300. The user moves the pointer 800 by manipulating the pointer mover 700 with his/her left hand, and places the pointer 800 on an execution file icon of an application to write documents. The user presses the auxiliary enter button 810 with his/her right hand to execute the application to write the documents.
If the application is executed, the user places the pointer 800 in a document-writing region of the application. Then, the user presses the left input button group 500 with his/her left thumb, and the right input button group 600 with his/her right thumb to input characters.
If a user wants to input Hangul, the Korean characters, the user presses the Korean/English conversion button 660 with his/her right hand. Then, the user may input Hangul with the left and right general character button groups 510 and 610. If the user wants to input the alphabet, the user presses the Korean/English conversion button 660 again.
A method of using the left shift button 520 will now be described. For example, if a user wants to inputwhich means yes in Korean, since bothandKorean vowels, are written in a single button of the right general character button group 610, if a user presses the single button only, is inputted. To inputa user presses the single button while pressing the left shift button 520 or the right shift button 620.
Accordingly, to typefirst, the user pressesa Korean consonant, and, as button is included in the right input button group 600, a user may have difficulty in pressing the button while pressing the right shift button 620. Then, a user may press thebutton with his/her right hand while pressing the left shift button 520 with his/her left hand, thereby inputtingin the application.
According to the foregoing principle, a user may press the right shift button 620 to input characters of buttons included in the left input button group 500.
The special character buttons and function buttons that may be included in the left and right input button groups 500 and 600 are provided below the left and right general character button groups 510 and 610 to be adjacent to user's both hands, thereby enabling a user to access the buttons without difficulty.
Since the space button 630 is used most frequently it can be larger than other buttons to be easily pressed by a user.
As the left and right input button groups 500 and 600 are respectively provided in the left and right panels 120 and 130 of the display part 300, a user may input characters without difficulty.
The character input keyboard of the computer interface from which the left and right input button groups 500 and 600 are selected may include not only general characters such as the alphabet, but also special characters and the function buttons selected in consideration of a frequency of usage. The buttons can be arranged in consideration of a user's usage environment so that a user inputs characters more easily.
As the pointer mover 700 and the auxiliary button 800 are provided, a user may move the pointer 800 to the predetermined object displayed on the display part 300 to select the object and perform the pop-up function. That is, the pointer mover 700 and the auxiliary button 800 support an input function of the left and right input button groups 500 and 600.
As described above, buttons of a conventional key board used in a computer cannot be divided into at least two groups separated and/or disposed opposite to each other with respect to a display part. The two separate groups of the buttons may be disposed on two separate boards other than the main board or may be connected to two different portions of the main board. A combination of at least one button of one of the two button groups and at least one button of the other one of the two button groups can constitute a word or character to be displayed on the display part.
As described above, the present general inventive concept provides a portable computer in which a user inputs characters without difficulty, and which improves user's convenience.
The present general inventive concept also provides a portable computer which arranges character buttons in consideration of a user's character input habit and improves user's accessibility.
The present general inventive concept also provides a portable computer which prevents an image displayed on a display part from being interrupted when inputting characters to enable a user to check the image without difficulty.
Further, the present general inventive concept also provides a portable computer which prevents a display part from being damaged when a user inputs characters, extends a lifespan thereof, improves versatility, and satisfies user's demands.
