Navigation Device Completion Suggestion Display Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation devices in vehicles require users to manually select and enter characters or symbols for destinations, which can be time-consuming and distracting, especially while driving, as they often lack intuitive completion suggestions for quick input.
Innovation Solution
A navigation device with an operating and display system that displays completion suggestions immediately next to selected characters or symbols, allowing users to easily select and combine alphanumeric characters or symbols, using a memory device to store data and process user inputs for predefinable criteria, thereby reducing the time and attention required for input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual character selection is used for navigation input, then input accuracy can be ensured, but input time and driver distraction increase significantly
Solution Approach 1:
The system pre-calculates and displays completion suggestions before the user finishes typing, showing possible completions immediately after a few characters are entered. This allows the user to see potential matches early and make faster decisions, reducing overall input time while maintaining accuracy through selective confirmation of pre-computed suggestions
Solution Approach 2:
The system provides real-time feedback by displaying completion suggestions dynamically as the user types. This immediate feedback loop allows users to verify if suggested completions match their intended input, ensuring accuracy while significantly reducing the time needed to complete navigation queries compared to manual character-by-character selection
2Measurement precision
If manual character selection is used for navigation input, then input accuracy can be ensured, but driver distraction and safety risks increase
Solution Approach 1:
By pre-computing and displaying completion suggestions after only a few characters are typed, the system minimizes the time the driver needs to spend on input operations. The driver can quickly review and confirm suggestions with minimal attention diversion from the road, reducing distraction-related safety risks while maintaining input accuracy
Solution Approach 2:
Real-time display of completion suggestions provides immediate feedback that allows drivers to quickly verify and confirm inputs with minimal cognitive load and attention shift from driving. This reduces the duration and intensity of distraction compared to manual character selection, thereby lowering safety risks while preserving input accuracy
3Productivity
If completion suggestions are displayed in the immediate vicinity of selected characters, then user input speed increases, but display complexity increases
Solution Approach 1:
Completion suggestions are displayed locally in the immediate vicinity of the selected character position rather than in a separate location. This localized display approach allows users to quickly associate suggestions with their current input context, increasing input speed while the complexity is managed by only showing relevant local completions rather than all possible options

AI summary
The invention relates to a device associated with a vehicle and comprising: an operator control, which can be used to select at least alphanumeric characters and/or symbols and to combine said characters and/or symbols in a character- or functional group; a display device, which can be used to display selectable characters and/or symbols in at least one selection field (2) and to display selected characters, symbols, character- or functional groups in at least one entry field (3), using a display system (1); a memory system with data stored therein; and a data processing system for selecting data from the data stored in the memory system according to predefinable criteria, taking into consideration the characters and/or symbols previously selected by a user. The device is configured to display a completion suggestion (4) on the display system (1), in close proximity to a character or symbol chosen in the selection field (2), said suggestion having at least one completion element, provided that the data processing device has determined a completion option for the previously selected character(s) and/or symbol(s) on the basis of the data in the memory system, taking into consideration the character(s) and/or symbol(s) previously selected by a user and the character or symbol chosen by the user; the at least one completion element can be chosen by a user by means of the operator control; and a chosen completion element can be selected by the user by means of the operator control.
