Mobile Device Key Input Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In portable electronic devices, when a key assigned to both numeric and non-numeric characters is pressed on the initial screen, it is difficult to determine the user's intended input, leading to potential misinterpretation of inputs as either numeric or non-numeric characters are ignored.
Innovation Solution
The device displays both numeric and non-numeric characters assigned to a key simultaneously on separate screen areas, allowing the user's intention to be reflected by activating one character while suppressing the other, and performing specific processing based on the key pressed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If priority is given to input of non-numeric character, then non-numeric character input is improved, but numeric character input is ignored
Solution Approach 1:
The patent divides the display area into two separate regions: a first display region for non-numeric characters and a second display region for numeric characters. This segmentation allows both character types to be displayed simultaneously without conflict, enabling the system to preserve both numeric and non-numeric input capabilities rather than forcing one to take priority over the other.
2Ease of operation
If priority is given to input of numeric character, then numeric character input is improved, but non-numeric character input is ignored
Solution Approach 1:
The display interface is segmented into distinct regions for different character types. The first display region handles non-numeric characters while the second display region handles numeric characters, allowing both input modes to function reliably simultaneously without one suppressing the other.
3Device complexity
If only one character type is displayed, then display simplicity is improved, but user intention accuracy deteriorates
Solution Approach 1:
The patent implements a segmented display structure with a first display region for non-numeric characters and a second display region for numeric characters. This segmentation enables the simultaneous display of both character types, allowing the system to accurately detect user intention by showing which character type is currently active without significantly increasing overall display complexity.

AI summary
Provided is a mobile electronic device capable of reflecting a user's intention. While an initial screen for waiting for an incoming-call is being displayed on an LCD display unit, a control unit performs control so that a first type character display area and a second type character display area are displayed on the LCD display unit in place of the initial screen, wherein the first type character display area is an area for, when any of first keys is depressed, displaying a first type character (for example, a number such as “1”, “2”, “3”) assigned to the depressed first key and the second type character display area is an area for displaying a second type character (for example, “a”, “i”, “u”, etc. in Japanese Hiragana letter) assigned to the depressed first key.
