Vehicle OS Overlapping Preview Target Area Reduces Gaze Shifts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle operating systems require users to constantly change their gaze and reorient themselves when entering character strings, leading to user fatigue and increased risk of distraction, particularly when entering city names or text for navigation systems.
Innovation Solution
An operating system with an overlapping preview and target area in the selection field, arranged to allow users to view both areas simultaneously, combined with a spell wheel design that moves alphanumeric characters along an arc, reducing the need for frequent gaze changes and incorporating visual differentiation to guide the user's attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the selection field and input field are arranged separately (non-overlapping), then the layout is simple and clear, but the user must constantly shift gaze between fields causing user fatigue and distraction
Solution Approach 1:
The selection field and input field are merged into a single overlapping display area where the selection field is positioned directly over the input field. This allows the user to view both the current input and the selectable characters simultaneously without shifting gaze, directly resolving the contradiction between operational ease and layout simplicity.
Solution Approach 2:
The selection field is arranged in a vertical column format overlapping the horizontal input field, creating a two-dimensional layered display. This dimensional arrangement allows both fields to occupy the same screen space without interfering with each other's readability, reducing the need for gaze shifts while maintaining clear visual separation of functions.
2Ease of operation
If the alphanumeric characters are arranged in a large circular path, then all characters are visible, but the user must reorient themselves frequently increasing distraction risk
Solution Approach 1:
The circular arrangement of alphanumeric characters is segmented into a vertical column format with a limited number of characters visible at once. The preview area displays only the currently selected character, while the input field shows the complete character string being constructed. This segmentation eliminates the need for continuous reorientation while maintaining easy character selection through the vertical scrollable format.
3Ease of operation
If the marker element moves along a circular path, then character selection is intuitive, but the user must constantly track marker position causing mental fatigue
Solution Approach 1:
Instead of moving the marker element along a circular path to indicate character selection, the invention inverts the approach by displaying the selected character directly in the preview area and allowing vertical scrolling of the character column. This inversion eliminates the need for marker tracking while maintaining intuitive selection through direct visual feedback in the preview area.

AI summary
The present invention proposes an operating system for inputting a character string in a vehicle, wherein the operating system comprises a display device with a display area, an input element, and a control device coupled to the display device and the input element, and with which a display on the display area can be controlled, wherein the display area can be controlled by the control device such that an input field with a target area provided for the input of an alphanumeric character and a selection field with a preview area in which a single alphanumeric character from a group of alphanumeric characters provided by the selection field is arranged is displayed on the display area, wherein the operating system is designed such that by actuating the input element, the alphanumeric character in the preview area can be changed and/or selected for insertion into the target area.characterized in that the preview area and the target area are arranged overlapping or adjacent to each other.
