Motion Remote Character Input via Category Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input methods using motion remote control devices for character information are cumbersome and inefficient, as they require manual selection of characters on an on-screen keyboard, making it difficult to input information quickly and accurately.
Innovation Solution
A system where character information is classified by category and stored on a memory unit, with a mapping table linking motion information from a remote control to corresponding character information, allowing for easy selection and input of characters using motion direction, and enabling correction through predetermined keys.

Engineering Contradiction Analysis
1Ease of operation
If an on-screen keyboard is used for character input with a motion remote control, then character information can be input, but the input process becomes cumbersome and time-consuming
Solution Approach 1:
The character set is segmented into multiple categories (e.g., Korean characters divided into initial consonants, vowels, and final consonants). Each category is assigned to a specific key on the remote control, allowing users to input characters by pressing category keys followed by motion input, rather than searching through a complete on-screen keyboard.
Solution Approach 2:
Categories of character information are pre-arranged and assigned to remote control keys before input begins. The system pre-processes and organizes character data by category, so when a user presses a category key, the corresponding character set is immediately activated and ready for selection through motion input, eliminating the need to navigate through all characters sequentially.
2Productivity
If character information is classified by category and stored in memory, then input efficiency improves, but device complexity increases
Solution Approach 1:
The remote control keys serve multiple functions: they act as both category selection keys and motion reference points. The same hardware components (remote control, display, motion sensor) are utilized for both traditional remote control operations and the new category-based character input system, eliminating the need for additional specialized hardware.
Solution Approach 2:
The system automatically performs category selection and character matching based on the motion direction detected. When a user presses a category key and moves the remote control, the system autonomously identifies the intended character by correlating the motion direction with the character positions in the displayed category, without requiring manual selection or complex user interaction.

AI summary
Embodiments relate to classifying character information to be input by category and inputting the information classified by category by using the motion information of a motion remote control working as an input unit. Character information input according to embodiments is as follows. At least one of a mode and a key to input information is selected, a category including information to be input is selected, and by moving an in input unit to be corresponded to the information direction in the category activated on a display device on the basis of the selection, character information is input/output on the display device on the basis of the motion direction information.
