Programmable Passenger Controller for In-Flight Entertainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-flight entertainment systems face limitations due to inflexible remote control units that require users to switch focus between the control unit and video display, restricting multitasking and accommodating diverse passenger needs, such as language customization, which is costly and inconvenient.
Innovation Solution
A programmable passenger controller with a network interface, display device, and processing unit that communicates with video display units via data networks, using near field communications for pairing and establishing wired or wireless connections, allowing for customizable interfaces and simultaneous content display on both the controller and video display units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed remote control unit with mechanical buttons is used, then the control structure is simple and reliable, but the adaptability for different languages and customization needs is poor
Solution Approach 1:
The remote control unit transitions from a static fixed-button interface to a dynamic display-based interface that can change its layout, labels, and functionality based on passenger selection. The display device allows the control interface to be reconfigured software-wise for different languages and preferences without hardware changes.
Solution Approach 2:
The system changes the parameter of the control interface from fixed physical button configurations to variable display-based configurations. By modifying the display content and control mapping parameters, the system adapts to different languages and passenger needs without physical hardware changes.
2Ease of operation
If users manipulate buttons on a remote control unit, then the control function is achieved, but users must repetitively shift focus between the remote control unit and the video display unit
Solution Approach 1:
The system merges the control interface and the video display interface into a unified interaction system. The same display device that shows video content also displays the control interface, eliminating the need for separate focus shifting between distinct control and display units.
Solution Approach 2:
The display device serves multiple functions: displaying video content, showing control interfaces, and providing feedback. This multi-functionality consolidates the interaction paradigm, allowing users to access controls directly on the display without switching attention to a separate remote control unit.
3Ease of operation
If a graphical user interface is overlaid on video content displayed on the video display unit, then control functions are integrated, but the GUI blocks a substantial portion of the video display unit's displayable surface
Solution Approach 1:
The control interface is moved from the two-dimensional video display surface to a separate interaction dimension via the remote control unit's display. This allows the video content to occupy the full area of the video display unit while controls are accessed through a different interface dimension on the remote device.

Data Source
AI summary
A controller is disclosed that controls an entertainment system which includes a video display unit that is separate from the controller. The controller includes a network interface, a display device, and a processing device. The network interface communicates with the video display unit via at least one data network. The processing device communicates a first command over the at least one data network to control a display of first content on the video display unit, and controls a display of second content on the display device of the controller. The second content is displayed concurrently with the first content. Related entertainment systems are disclosed.
