Embodiment Construction

[0032] The content of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 as shown, figure 1 It is a structural block diagram of the present invention. The invention is realized based on Microwindows graphics engine and Flnx control library. The invention includes a communication module, a control module, a storage module, a display module and an output module. The soft keyboard is implemented as a client program of Microwindows. The key values ​​of the remote control are read by the underlying driver of Microwindows. The communication module obtains the key values ​​through communication with the Nano-X server and transmits them to the control module. The control module performs corresponding processing according to the key values ​​of the remote controller. The control module further includes a selection unit and a state switching unit, wherein the selection unit is used to select the ke...

Abstract

A method for inputting characters includes receiving control command transmitted from outside, carrying out selection in stored soft keyboard state boundary according to received control command, displaying selected state boundary on display screen, selecting required key from state boundary according to said control command, outputting selected result and displaying selected result on display screen. The device used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to an input device, in particular to a character input device used in electronic products mainly operated by remote controllers. Background technique [0002] In equipment such as IPTV set-top boxes and conference TV terminals, the remote control is generally used to directly input symbols, English and numbers. This input method is inefficient and difficult to operate. Using the soft keyboard instead of directly using the remote control for input will greatly improve the input speed and accuracy, and also give users a good experience. There are many kinds of existing soft keyboard designs, but many of them require a touch screen and a mouse to assist input, which is not suitable for embedded terminals that use remote controls as the main control input tools, such as set-top boxes; other soft keyboard designs, in The design of functions such as symbol switching is too complicated, difficult to remember and use, or small but not co...
