Navigation Device Historical Data Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices lack the ability to automatically provide historical information to users when they are in proximity to significant locations, limiting their utility in historical tours or entertainment during journeys.
Innovation Solution
A navigation device equipped with a processor, audio and display output, and a data store for map and historical data, which uses location identifiers to convey historical information as audio or visual outputs when the device is near identified locations, allowing users to explore historical sites without prior knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If navigation devices only provide basic routing functionality, then device complexity is reduced, but utility and user engagement are limited
Solution Approach 1:
The navigation device is enhanced with multiple functions beyond basic routing, including historical information retrieval, location-based information delivery, and interactive user features. The system universally handles various data types (routing data, historical data, location data) through a single integrated processor, allowing the device to serve multiple purposes such as navigation, education, and entertainment simultaneously.
Solution Approach 2:
Historical information and location identifiers are pre-stored in the device's memory before the user needs them. The system proactively prepares and organizes historical data associated with specific locations along the planned route, so that when the user approaches a location, the information is immediately available for delivery without requiring real-time data retrieval or processing delays.
2Adaptability or versatility
If historical information is continuously displayed, then user engagement increases, but information delivery becomes irrelevant and distracting
Solution Approach 1:
The system continuously monitors the user's current location through GPS or other positioning mechanisms and compares it with the planned route and associated historical locations. This feedback loop enables the system to determine when the user is in proximity to a location with historical information, triggering information delivery only at appropriate moments. The system adjusts information delivery based on real-time location feedback, ensuring relevance and timing.
Solution Approach 2:
Instead of continuous information delivery, the system uses periodic checks of user location against predefined historical locations along the route. Information is delivered at discrete intervals when the user approaches specific locations of interest, creating a rhythm of engagement that maintains user attention without overwhelming them with constant information streams.
3Adaptability or versatility
If multiple data types are stored in memory, then functionality is enhanced, but memory requirements and processing load increase
Solution Approach 1:
The data storage is segmented into distinct categories: routing data, historical data, and location data, each with its own data structure and organization. This segmentation allows the system to efficiently manage and retrieve specific types of data without processing the entire dataset. The processor can access only the relevant segment of data needed for the current operation, reducing processing load despite the overall volume of stored information.
Data Source
AI summary
A navigation device includes a locator for determining a location of the navigation device, a processor, an audio output device and/or a display controllable by the processor, and a store for map data and historical data. The historical data includes historical information about a location and a location identifier identifying the location. The processor is arranged to control the audio output device and/or display to convey the historical information as an audio and/or visual output in response to the processor determining from the locator that the navigation device is in the vicinity of the location identified by the location identifier.
