Vehicle Touch Input Concave Area Character Selection UI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As vehicles become increasingly equipped with various functions, drivers face increased operating loads and difficulties in using these features, leading to decreased concentration on driving due to the complexity of controlling multiple functions.
Innovation Solution
A vehicle with a touch input apparatus featuring a concave area for detecting touch gestures, allowing for the display of character input UIs that show pre-stored completed character combinations, enabling drivers to easily select and control vehicle functions by touching the interface without complex manipulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vehicle has more functions, then the passenger's convenience is improved, but the driver's operating load increases
Solution Approach 1:
The system pre-stores multiple completed character combinations corresponding to different input character combinations in advance. When the driver inputs a character combination, the system automatically displays the pre-prepared completed combinations, eliminating the need for manual completion and reducing operating load.
Solution Approach 2:
The system creates visual copies of completed character combinations on the display unit based on the input. These displayed combinations are replicas of the pre-stored data, allowing the driver to select from visual representations without performing the actual typing or manipulation work.
2Adaptability or versatility
If a vehicle has more functions, then the passenger's convenience is improved, but the driver's concentration on driving deteriorates
Solution Approach 1:
By preparing completed character combinations in advance and automatically displaying them, the system minimizes the time and attention the driver needs to spend on input operations, allowing the driver to maintain concentration on the road while still accessing vehicle functions.
Solution Approach 2:
The system performs the work of completing character combinations automatically without requiring continuous driver intervention. The automatic display and selection mechanism serves itself, reducing the cognitive load on the driver.
3Measurement precision
If manual character input is required, then input precision is achieved, but the time and effort required increases
Solution Approach 1:
The system pre-stores multiple completed character combinations that correspond to different input character combinations. This preliminary preparation allows the driver to input characters quickly and have the completed combinations automatically displayed, eliminating the time-consuming process of manual completion while maintaining input accuracy through the driver's initial character selection.

AI summary
A vehicle includes a display unit for displaying a first character input User Interface (Ul) in which a plurality of characters are arranged to surround a predetermined reference point, a touch input apparatus having a concave area for detecting a touch gesture of selecting one character of the plurality of characters, and a controller for controlling the display unit to display, wherein if the number of pre-stored completed character combinations corresponding to an input character combination configured with at least one character sequentially selected according to the touch gesture detected by the touch input apparatus is smaller than or equal to a threshold value, a second character input Ul in which the completed character combinations corresponding to the input character combination are arranged to surround the reference point.
