Portable Electronic Device In-Flight Navigation Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-flight information distribution systems are limited to display units installed on aircraft, failing to provide information to portable electronic devices, particularly those with limited 'display real estate' such as wearable devices, which restricts the presentation of relative locations of points of interest outside the aircraft.
Innovation Solution
A system and method that includes a discovery datagram generator and a flight navigation datagram generator to broadcast information to portable electronic devices, using a directional pointer and location symbols scaled to angular bearings, enabling the presentation of relative locations on devices with limited display space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If in-flight information distribution systems use display units installed on aircraft, then information can be presented to passengers, but the system cannot distribute information to portable electronic devices with limited display space
Solution Approach 1:
The patent applies local quality by adapting the information presentation to the specific constraints of portable devices. The system transforms comprehensive flight information into condensed, location-specific representations that match the limited display real estate of PEDs while maintaining critical information quality
Solution Approach 2:
The system changes the parameters of information presentation by using angular bearings instead of absolute distances, and by scaling location indicators dynamically based on device screen dimensions. This allows the same information to be effectively displayed across devices with varying display areas
2Loss of information
If the system presents detailed location information on portable devices, then passengers gain access to flight data, but the limited display real estate cannot accommodate comprehensive information
Solution Approach 1:
The patent extracts only the most critical location information for presentation on portable devices. By separating essential data (angular bearing to next point of interest) from detailed data (comprehensive distance and coordinate information), the system maintains information utility while adapting to display constraints
Solution Approach 2:
The system transitions from two-dimensional map displays to a radial dimension-based presentation using angular bearings. This dimensional change allows location information to be effectively represented in a compact format that preserves spatial relationships without requiring extensive display area
3Area of stationary object
If the system uses angular bearing indicators on portable devices, then location information fits limited display space, but the presentation complexity increases
Solution Approach 1:
Instead of adapting the display to show traditional map coordinates, the system inverts the approach by using angular bearings radiating from the aircraft position. This inversion simplifies the visualization on small screens by organizing information around the user's current location rather than requiring a broader geographic context
Data Source
AI summary
A system, method, and indicator for distributing, generating, and presenting relative locations of points of interest to a viewer are disclosed. A distribution system may include a discovery datagram generator and a flight navigation datagram generator for broadcasting a discovery datagram and flight navigation datagram, respectively, to a portable electronic device (PED), where the flight navigation datagram may be comprised of navigation data representative of flight navigation information. A generating method may be performed by the PED configured to listen for and receive the discovery datagram; listen for and receive the navigation datagram continuously; and generate a display data set representative of the indicator continuously, where the indicator includes a directional pointer, a first rounded indicator, a second rounded indicator, and one or more location indicators, where each location indicator indicates a relative bearing to a point of interest measured with reference to the directional pointer.
