Digital Assistant Voice Interface for In-Flight Entertainment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-flight entertainment (IFE) systems lack an efficient way for passengers to discover content and for crew to find and execute control functions, leading to a suboptimal passenger experience and operational inefficiency.
Innovation Solution
Implementing a natural language digital assistant that interacts with users on transportation vehicles, processing voice or text inputs to provide information and perform actions related to entertainment, crew requests, and system control, using a voice-to-text module, natural language parser, and trained interpreter to associate user requests with machine-readable inputs and execute commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional IFE systems use traditional menu navigation interfaces, then system control functionality is provided, but user interaction complexity and time to discover content increase
Solution Approach 1:
The patent replaces the mechanical menu navigation system with a voice-activated natural language processing system. Users can speak commands like 'play movie' or 'show me comedy' instead of manually navigating through hierarchical menus, directly substituting physical interaction mechanics with acoustic field-based interaction.
Solution Approach 2:
The natural language processor acts as an intermediary between the user and the IFE system controls. It translates spoken language into system commands, bridging the gap between human communication and machine execution without requiring users to learn specific interface navigation patterns.
2Adaptability or versatility
If IFE systems provide comprehensive control functions, then system capability increases, but interface complexity and operational difficulty increase
Solution Approach 1:
The voice command system serves as a universal interface that can execute multiple different control functions through a single interaction mode. Whether controlling entertainment, lighting, or cabin systems, the same natural language processing mechanism handles diverse commands, eliminating the need for separate control interfaces for each function.
Solution Approach 2:
The system includes trained interpreters and natural language processors that automatically understand and execute user intent without requiring manual configuration or complex setup. The system adapts to user commands autonomously, reducing the operational burden on passengers and crew.
3Productivity
If traditional control interfaces are used, then system functionality is maintained, but operational efficiency for crew and passengers decreases
Solution Approach 1:
The patent replaces manual control operations with voice-activated commands processed through natural language interpretation. This substitution accelerates the control execution process by eliminating the need for sequential menu navigation and direct manual interaction with physical controls.

AI summary
Methods and systems for a transportation vehicle are provided. For example, one method includes receiving a user input by a processor executable, digital assistant at a device on a transportation vehicle; determining by the digital assistant a relationship between words of the user input; using a trained dataset by the digital assistant to ascertain an intended action based on the user input; and providing a response by the digital assistant for the user input, where the response includes performing the intended action using another device on the transportation vehicle.
