CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority to Chinese Patent Application No. CN201310043018.0, filed on Feb. 5, 2013, in the State Intellectual Property Office of RR. China, which is hereby incorporated herein in its entirety by reference.

FIELD OF THE INVENTION

The invention relates generally to the field of communications, and more particularly to a method for a remote control to input characters to a display device.

BACKGROUND OF THE INVENTION

As content ends get rich and Internet technologies develop, how to use a remote control to rapidly input a character to a television is urgently desired.

As shown in FIGS. 1 and 2, in a conventional input method, numeric keys 1 to 9 on the remote control are multiplexed. For example, in order to input a Chinese character, e.g., “”, the following steps need to be performed.

Step A: A television is set to enter an interface for inputting characters.

Step B: Press in sequence a “6” button, a “4” button, the “6” button and the “4” button on a remote control, so that the television shows an interface shown in FIG. 2.

Step C: Press a Down button among arrow buttons on the remote control to move a cursor to a Chinese character display area.

Step D: Press a Right button among the arrow buttons on the remote control to move the cursor to “”.

Step E: Press an Ok button on the remote control to input the character “” at the cursor into an input box.

The method for a remote control to input a character to a television in the prior art has the following shortcomings.

Character inputting involves many buttons, and the distances between the involved buttons are long, which makes functional buttons of the remote control complicated and reduction of the remote control in size very difficult. In addition, during character inputting, attention needs to be shifted between the remote control and the television constantly, which likely results in visual fatigue.

Therefore, a heretofore unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.

In accordance with the purposes of this disclosure, as embodied and broadly described herein, this invention, in one aspect, relates to a method for a remote control to input characters to a display device.

In one embodiment, a method for a remote control to input characters to a display device is shown in FIGS. 3-5. FIG. 3 is a schematic flow chart of a first embodiment of the method for a remote control to input characters to a display device according to the invention. FIG. 4 is a schematic view of a remote control suitable for the method for a remote control to input characters to a display device shown in FIG. 3. FIG. 5 is a schematic view of a first state of an input box and a soft keyboard in the method for a remote control to input characters to a display device shown in FIG. 3. In this embodiment, the method for a remote control to input characters to a display device includes the following steps.

Step a: In response to a character input request sent by a remote control, display an input box and a soft keyboard, where the soft keyboard includes a plurality of preset characters arranged one by one.

When a character needs to be input to a display device through the remote control, the remote control sends the character input request, and upon receiving the character input request, the display device displays the input box and the soft keyboard. The soft keyboard may be designed into multiple kinds according to input modes. The input modes may include a pinyin input method, an English input mode, a five-stroke input mode, a stroke input mode, a digit input mode, an expression input mode, and a symbol input mode. For example, when the input mode is the pinyin input mode, the soft keyboard includes 26 letter characters arranged one by one. For another example, when the input mode is the digit input mode, the soft keyboard includes ten numeric characters, 0-9, arranged one by one.

Step b: In response to a position movement instruction sent by an arrow button on the remote control, move a cursor to a target character.

The cursor on the display device may move according to the position movement instruction that is sent after the arrow button on the remote control is triggered. For example, after Left and Right buttons among the arrow buttons on the remote control are triggered, a position movement instruction is sent, so as to make the cursor move between the input box and the soft keyboard. For another example, when the cursor is located in the soft keyboard, after Up and Down buttons among the arrow buttons on the remote control are triggered, a position movement instruction is sent, so as to make the cursor move between several characters in the soft keyboard.

Step c: In response to an input confirmation instruction sent by an Ok button on the remote control, input the target character to the input box.

When the cursor is on a certain character, the Ok button on the remote control can make the character at the cursor be input into the input box.

In the method for a remote control to input characters to a display device provided by the invention, in response to the character input request sent by the remote control, the input box and the soft keyboard are displayed. The soft keyboard includes a plurality of preset characters that are arranged one by one. In this case, character inputting may be performed through the arrow buttons and the OK button on the remote control. When the position movement instruction sent by the arrow button on the remote control is received, the cursor moves until reaching the target character. When the input confirmation instruction sent by the Ok button on the remote control is received, the target character at the cursor is input to the input box, thereby completing the character inputting. According to the invention, the characters on the soft keyboard are arranged one by one, and thus character inputting only involves the arrow buttons and the OK button, and not only the distance between the required buttons is shortened, and a character inputting speed is improved, but also the number of buttons required by the character inputting is decreased, thereby achieving the objectives of simplifying the design of the remote control and decreasing the volume of the remote control. Meanwhile, shifting of attention between the remote control and the television set is avoided, so as to alleviate visual fatigue incurred by character inputting, and eliminate input errors, thereby greatly improving user experience.

The input modes may include the pinyin input mode, the English input mode, the five-stroke input mode, the stroke input mode, the digit input mode, the expression input mode, and the symbol input mode, and a user can select any input mode according to needs. That is to say, when the soft keyboard includes pinyin characters, English characters, numeric characters, symbol characters, and five-stroke radical characters that are preset and arranged one by one, the soft keyboard needs to switch between the pinyin characters, the English characters, the numeric characters, the symbol characters, and the five-stroke radical characters. Referring to FIG. 6, which is a schematic flow chart of Step a in the method for a remote control to input characters to a display device shown in FIG. 3, in a specific embodiment, Step a in the method for a remote control to input characters to a display device shown in FIG. 3 includes the following specific steps.

Step a1: According to a received character input instruction, display an input box and a default soft keyboard.

Step a2: According to a received input method switch instruction, switch the default soft keyboard to a target soft keyboard.

The default soft keyboard may include pinyin characters, or English characters, or numeric characters, or symbol characters, or five-stroke radical characters, which are preset and arranged one by one. For example, the default soft keyboard is the soft keyboard corresponding to the pinyin input mode, that is, the soft keyboard displays 26 letter characters that are arranged one by one. In order to input a digit, a user sends an input method switch instruction through the remote control, and the display device, in response to the input method switch instruction, switches the current soft keyboard corresponding to the pinyin input mode to the soft keyboard corresponding to the digit input mode, that is, switches the 26 letter characters that are arranged one by one to 10 numeric characters, 0-9, that are arranged one by one.

Definitely the input modes in the method for a remote control to input characters to a display device according to the invention are not limited to the aforementioned manner. For example, only one input mode may exist, that is, no input method switch operation needs to be performed, and in this case, the soft keyboard includes pinyin characters, English characters, numeric characters, symbol characters, or five-stroke radical characters, which are preset and arranged one by one. In other embodiment variations, alternatively, the soft keyboard may include a combination of letter characters, numeric characters, and symbol characters, that are preset and arranged one by one, and in this case no input method switch operation needs to be performed either.

FIG. 7 is a schematic flow chart of a first embodiment of Step a2 shown in FIG. 6. In the specific embodiment, Step a2 shown in FIG. 6 includes the following specific steps.

Step a21: Receive an input method switch instruction sent by a Menu button on the remote control.

Step a22: According to the received input method switch instruction, switch the default soft keyboard to a target soft keyboard.

In order to conveniently and rapidly switch the input method, the remote control is provided with a shortcut button for switching the input method. Definitely, the exiting Menu button on the remote control may be multiplexed for switching the input method.

FIG. 8 is a schematic flow chart of a second embodiment of Step a2 shown in FIG. 6. In the specific embodiment, Step a2 shown in FIG. 6 includes the following specific steps.

Step a23: In response to a position switch instruction sent by the Left and Right buttons on the remote control, move the cursor to the input box or the soft keyboard.

Step a24: When the cursor is in the input box, in response to an input method switch instruction sent by the Up button on the remote control, switch the default soft keyboard to the target soft keyboard.

In this embodiment, during the input method switch operation, the cursor needs to be moved to the input box before the input method switch operation can be performed. It should be understood that, the remote control sending the position switch instruction is not limited to be triggered by the Left and Right buttons, and the remote control sending the input method switch instruction is not limited to be triggered by the Up button either, which may be designed according to use habits and intuitiveness.

When a numeric character needs to be input, the soft keyboard displays 10 numeric characters, 0-9, which are arranged one by one. The soft keyboard in this case may be referred to FIG. 9, which is a schematic view of a second state of the input box and the soft keyboard in the method for a remote control to input characters to a display device shown in FIG. 3. Operations performed to input a character “3” are taken as an example below to describe the embodiment of the invention.

1. The remote control sends a character input request. The display device displays an input box and a soft keyboard. In this case, the soft keyboard is as what is shown in FIG. 9.

When the current soft keyboard is not for numeric characters, an input method switch operation needs to be performed.
