Transparent Keypad with Periodic Transparency for Smart Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying a keypad on smart devices, such as touch screens, often cause user confusion due to overlapping input and output windows, leading to increased typographical errors and difficulty in recognizing key positions, especially when using Latin-based text or special characters.
Innovation Solution
A method where the keypad is displayed in a transparent or translucent manner overlapping with the output window, with periodic changes in transparency or color, allowing wider availability of both windows and reducing confusion by facilitating key recognition without requiring users to memorize key positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the keypad is displayed in a translucent manner overlapping with the output window, then both input and output windows are available over a wide area, but the content of the keypad is not easily seen and confusion with the output displayed on the screen occurs
Solution Approach 1:
The patent applies periodic action by making the keypad transparency change over time in cycles. The keypad alternates between translucent states with different transparency levels, allowing users to periodically see the keypad content clearly while maintaining the overlapping display configuration. This temporal variation resolves the contradiction by providing visibility at specific moments without requiring the keypad to be fully opaque at all times.
Solution Approach 2:
The patent applies dynamics by making the keypad transparency dynamic rather than static. The transparency level changes automatically over time, transitioning between different states of visibility. This dynamic adjustment allows the system to adapt between providing wide window area and ensuring keypad visibility, resolving the contradiction through temporal variation in the display properties.
2Ease of operation
If the transparency of frequently used keys is gradually increased by memorizing usage frequency, then users can remember key positions, but the user must still memorize key positions and typographical errors increase
Solution Approach 1:
The patent applies periodic action by cycling the keypad through different transparency states that highlight different keys at different times. Instead of permanently increasing transparency of frequently used keys, the system periodically makes all keys visible with appropriate transparency, allowing users to see key positions without needing to memorize them, thereby maintaining input accuracy.
3Area of stationary object
If the keypad is displayed with low transparency to maintain wide window area, then both windows are available over wide area, but the area obscured by the keypad increases and output window recognition becomes difficult
Solution Approach 1:
The patent applies periodic action by making the keypad transparency vary over time. During periods when the keypad is more transparent, the output window is clearly visible. During other periods, the keypad becomes less transparent to ensure key visibility. This temporal alternation resolves the contradiction by providing both wide display area and adequate recognition at different times.

AI summary
According to a method for displaying a keypad for a smart device of the present invention, a keypad can be displayed in a transparent or a translucent state by being overlapped with an output window displayed on a display module of a smart device such that both of an input window and the output window can be used over a wide area, and the transparency or color of the keypad periodically changes such that a user can check the keypad position which is displayed instantaneously, thereby enabling precise input operations without having to memorize all of the keypad positions and solving problems such as the confusion caused by overlapping the output window with the transparent keypad.
