Handheld Virtual Keyboard Syncing Text to Set Top Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing text input method for set top boxes using remote controllers is inefficient, requiring repeated operations with arrow keys to input text, making it complex and slow.
Innovation Solution
A virtual input method and apparatus that utilizes a handheld device to invoke an edit box, update display content, and synchronize text information with the set top box, allowing for efficient text input through a built-in input method, enabling operations like cutting, copying, and deleting on massive text.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the remote controller is used to input text information into the set top box by moving arrow keys to select letters and characters, then the text input can be completed, but the operation becomes complex and the efficiency becomes low
Solution Approach 1:
The patent introduces a handheld device as an intermediary between the user and the set top box for text input operations. The handheld device displays a virtual keyboard and captures user input, then transmits the text data to the set top box. This mediator eliminates the need for complex remote controller operations while maintaining system compatibility.
Solution Approach 2:
The patent replaces the mechanical remote controller system with a software-based virtual keyboard system running on the handheld device. Instead of physical arrow key movements and on-screen character selection, users interact with a digital keyboard interface that directly generates text input, substituting mechanical interaction with software-based input methods.
2Productivity
If the remote controller requires repeated operations of arrow keys to input each character, then text input can be achieved, but the operation complexity increases and time consumption increases
Solution Approach 1:
The patent creates a virtual copy of a physical keyboard display on the handheld device screen. This virtual keyboard copy allows users to input text by tapping displayed characters rather than navigating through multiple screens of letters and characters, significantly reducing input time while maintaining the familiar keyboard interaction model.
Solution Approach 2:
The virtual keyboard is pre-configured and displayed on the handheld device before text input begins. All necessary characters and formatting options are prepared in advance on the screen, allowing users to directly select needed characters without sequential navigation, thus performing the preparation work before the actual input process.
3Ease of operation
If the system uses a traditional input method requiring cursor movement among 26 letters and candidate character selection, then text input functionality is provided, but the number of operations required increases
Solution Approach 1:
The patent merges the letter selection and character selection functions into a single unified virtual keyboard interface. Instead of requiring separate operations for selecting from 26 letters and then from candidate characters, the virtual keyboard combines these functions, allowing users to directly tap the desired character in one operation, thereby reducing operational steps while maintaining full text input functionality.

AI summary
Embodiments of the present application disclose a text information input method and apparatus, where the method includes: firstly, invoking a first edit box of a handheld device; afterwards, updating display content of the first edit box according to an editing operation performed by an operator on the first edit box; and then, detecting whether first display content of the first edit box at a current moment and second display content of the first edit box at a previous moment are the same, and if they are different, sending the first display content to a set top box, so that the set top box updates display content of a second edit box.
