Dual Display Robot Controller for Dynamic Information Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to enhance efficiency in providing information by effectively combining two displays in moving robots, limiting their ability to provide guide services and wayfinding information in public places.
Innovation Solution
A moving robot equipped with a voice input unit, a first display capable of receiving touch inputs, and a second larger display, with a controller that dynamically manages which display to use based on the type and amount of information, interaction distance, and display sizes to improve information delivery and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single display is used in the robot, then the device complexity is reduced, but the information providing efficiency and user convenience deteriorate
Solution Approach 1:
The robot is equipped with two separate displays (first display and second display) that can be independently controlled. The controller selectively activates one display based on the type and amount of information to be provided, segmenting the information delivery function across multiple display devices to improve efficiency without requiring all displays to be active simultaneously.
Solution Approach 2:
The system dynamically selects which display to use based on real-time conditions including the type of information, amount of information, interaction distance between user and robot, and sizes of the displays. This dynamic adaptation allows the system to optimize information providing efficiency for different scenarios while managing complexity through intelligent control rather than hardware redundancy.
2Ease of operation
If a larger display is used, then the information visibility and user convenience improve, but the robot size and portability worsen
Solution Approach 1:
The display function is segmented into two displays of different sizes. The second display (larger) is used when more information needs to be displayed or when the user is at a greater distance, providing better visibility and convenience. The first display (smaller) is used for basic information or when compactness is needed, thus balancing user convenience with robot size constraints.
Solution Approach 2:
The system dynamically selects between the first and second displays based on interaction distance and information requirements. When the user is far away or needs detailed information, the larger second display is activated. When the user is close or only needs brief information, the smaller first display is used, thereby providing optimal user convenience while minimizing robot volume.
3Loss of information
If multiple displays are activated simultaneously, then the information capacity increases, but the energy consumption and device complexity increase
Solution Approach 1:
The controller dynamically determines which display to activate based on the type and amount of information that needs to be conveyed. Instead of keeping both displays active simultaneously, the system selectively activates only the necessary display (first or second) based on real-time information requirements, interaction distance, and display size characteristics, thereby maintaining information completeness while minimizing energy consumption.
Solution Approach 2:
Different displays are used for different information scenarios. The larger second display is allocated for information-heavy scenarios, while the smaller first display handles lightweight information tasks. This local optimization of display usage ensures that information completeness is maintained for each scenario type while energy consumption is minimized by not activating both displays simultaneously.

AI summary
A moving robot includes a voice input unit configured to receive a voice input of a user; a first display capable of receiving a touch input; a second display larger than the first display; and a controller configured to perform control such that a screen to be displayed in response to the voice input or the touch input is displayed on at least one of the first display or the second display based on a type and an amount of information included in the screen. Accordingly, it is possible to provide information and services more effectively using the two displays.
