The present disclosure relates to electronics and information technologies, and more particularly relates to an input method and an input device.
The input device has become more and more important since the appearance of the computers. The conventional input devices, such as previous keyboard and lately mouse, have brought convenience for operating the computer. In recent years, there has been widespread application of electronic devices equipped with touch screens. The touch screen can detect the presence and location of a touch within the display area, thus it may replace the keyboard. It has played a prominent role in the design of digital appliances such as tablet computers, mobile phones, personal digital assistant (PDA).
The conventional input devices, such as keyboard, mouse, and touch screen, are employed to different applications according to their unique features. However, those input devices also have some disadvantages. For example, the touch screen for a large display screen suffers from high cost and short operation distance; the keyboard is convenient for typing characters, but it is inconvenient to perform an operation in a graphic user interface (GUI), e.g. selecting one specific zone, etc; the mouse is the best choice for selecting in the GUI, but it needs a substantially flat surface to move around, thus the application environments of the mouse are limited.
Therefore, there is room for improvement within the art.
In one aspect of the present disclosure, it is desired to provide an input device which overcomes the inconvenience when operating the GUI via the keyboard.
In one embodiment, an input method includes: step S110, receiving a key instruction generated by a key pressed by a user; step S120, obtaining an input instruction according to the key instruction and a predetermined corresponding relationship, a relative position of a graphic zone affected by the input instruction in a GUI is corresponding to a relative position of a key zone of the key generating the key instruction in a keyboard according to the predetermined corresponding relationship, and step S130, inputting the input instruction.

According to the input method described above, the key of the keyboard are corresponding to the GUI according to their zone, such that when a key is pressed by the user to generate a key instruction, the graphic zone affected by the obtained input instruction is corresponding to the key zone, and the corresponding operations, similar to left click, double click, or right click of the mouse, can be performed to the corresponding graphic zone, thus facilitating the operation of the GUI.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
The conventional keyboard serves as an input device for inputting the characters only. In embodiments described below, various operations are performed according to a relative position of a key located in the keyboard, such that the functionality of the conventional keyboard is extended.
Referring to
In step S110, a key instruction generated by a key pressed by a user is received. The key instruction may be generated by a key from a standard PC keyboard, or a mobile phone keyboard or a remote control keyboard based on a conventional keyboard technology. Details of the conventional keyboard technology do not need to repeat in the present disclosure.
In step S120, an input instruction is obtained according to the key instruction and a predetermined corresponding relation between the input instruction and key instruction. The corresponding relation is predetermined to set a correspondence between a key zone of the key and a graphic zone affected by the input instruction. Referring to
It is to be understood that, the number of the key zone or the graphic zone may be varied accordingly, and the number is preferably more than two. There is a one-to-one correspondence between the key zones and the graphic zones. In a preferable embodiment, the relative position of the key zone of the key generating the key instruction in a keyboard is exactly the same as the relative position of the graphic zone affected by the input instruction in the GUI. For example, the first key zone 210 is located in a left side of the keyboard, and the first graphic zone 310 is also located in a left side of the GUI; the fourth key zone 240 is located in a middle portion of the keyboard, and the fourth graphic zone 340 is also located in a middle portion of the GUI. It is to be understood that, under some circumstances with less demanding, especially when the shape of the keyboard is not in accordance with that of the GUI, the corresponding relationship of the key zone and the graphic zone may not be strictly limited, as long as their relative positions are approximately corresponding with each other, similar operation could also be processed.
In the illustrated embodiment, one key zone of the keyboard includes at least two keys, and the key instruction generated by any keys in the same key zone is corresponding to the same input instruction. Under such configuration, instead of searching for one specific key, the user can simply press any keys in the corresponding key zone to operate the desired graphic zone. In order to prevent the misoperation, the at least two keys in one key zone are adjacent to each other in the keyboard.
In step S130, the input instruction is inputted. The input instruction may be customized. For example, the input instruction may be a click operation instruction in the graphic zone of the GUI. The click operation instruction may be similar to the left click of the mouse. The input instruction may also be the operation instruction similar to the right click or the double click of the mouse. The input instruction may also be zooming-in operation instruction, etc. When an operating system receives the input instruction, the user can perform the corresponding operations, such as open a new GUI, zoom in a graphic zone, etc.
According to the input method described above, the key of the keyboard are corresponding to the GUI according to their zone, such that when a key is pressed by the user to generate a key instruction, the graphic zone affected by the obtained input instruction is corresponding to the key zone, and the corresponding operations, similar to left click, double click, or right click of the mouse, can be performed to the corresponding graphic zone, thus facilitating the operation of the GUI.
In alternative embodiment, the input method further includes a step of defining the key zone of the keyboard and the graphic zone of the GUI to build a corresponding relationship between the key instruction and the input instruction. The definition of the key zone in the keyboard or the graphic zone in the GUI may be customized. For example, regarding to a complicated GUI, a relative large number of graphic zones can be defined, and the number of the key zone can be increased accordingly; on the contrary, regarding to a simple GUI, a relative small number of the graphic zones and a fewer key zones are preferred.
In a preferable embodiment, prior to step S110, the input method further includes a step of determining whether a zone input mode is activated. If the zone input mode is activated, the method proceeds from step S110 to step S130. If the zone input mode is not activated, the method enters the normal input mode, i.e. processing the key instruction generated by a pressed key in a normal way, such as typing characters. The ways to activate the zone input mode can be customized, for example, a predetermined set of keys are pressed simultaneously, or a specific switch on the keyboard is designated to activate or deactivate the zone input mode.
Referring to
The receiving module 410 is capable of receiving the key instruction generated by the key pressed by the user. The key instruction may be generated by a key from a standard PC keyboard, or a mobile phone keyboard or a remote control keyboard based on a conventional keyboard technology.
The matching module 420 is connected to the receiving module 410. The matching module is capable of obtaining an input instruction according to the key instruction and a predetermined corresponding relationship. The corresponding relationship is predetermined to set the correspondence between a key zone of the key and a graphic zone affected by the input instruction. Referring to
The input module 430 is capable of inputting the input instruction. The input instruction may be customized For example, the input instruction may be a click operation instruction in the graphic zone of the GUI. The click operation instruction may be similar to the left click of the mouse. The input instruction may also be the operation instruction similar to the right click or the double click of the mouse. The input instruction may also be zooming operation instruction, etc. When an operating system receives the input instruction, the user can perform the corresponding operations, such as open a new GUI, zoom in a graphic zone, etc.
The described input method and input device can be applied to set-top boxes. The keyboard is wirelessly connected to the set-top box, and the set-top box is connected to the TV set to display a GUI on the TV screen. For example, the keys “', 1, 2, 3, 4, 5, Tab, Q, W, E, R, T” of the remote control keyboard are defined as the first key zone; the keys “6, 7, 8, 9, 0, −, =, Backspace, Y, U, I, O, P, [, ], \” are defined as the second key zone; the keys “ Caps lock, A, S, D, F, G, left shift, Z, X, C, V, B” are defined as the third key zone; the keys “H, J, K, L, ;, ', enter, N, M, ,, ., /, right shift” are defined as the fourth key zone. Accordingly, the GUI defines the first graphic zone, the second graphic zone, the third graphic zone, and the fourth graphic zone. The first graphic zone can be information about newly published books of a website; the second graphic zone can be information about stocks; the third graphic zone can be information about news; the fourth graphic zone can be users' favorites (such as cars, entertainments or sports information). According to the method described above, when the user presses a key, e.g. “W” or “4”, in the first key zone to generate a key instruction, the input instruction opening information about newly published books will be inputted. When presses a key, e.g. “O”, in the second key zone, which is corresponding to the second graphic zone, the input instruction opening the information about stocks will be inputted. In conclusion, the user can quickly access the graphic zone in the GUI through the keyboard, other than the mouse or the touch panel, thus inputting becomes convenient. It is to be understood that, besides the set-top box and remote control for the set-top box, the described input method and input device can also be applied to TV set and remote control for the TV set, personal computer and keyboard for personal computer.
