Transparent Robot Display Control for Operator Information Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In interactive robot operating systems, both image information from cameras and actual peripheral information are often displayed simultaneously on a head-mounted display, leading to unnecessary information overload for operators, reducing work efficiency.
Innovation Solution
A robot system with a transparent display unit that only shows sensor-detected information when required, allowing operators to focus on the physical world and reducing information overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If both image information from camera and actual peripheral information are displayed simultaneously on head-mounted display, then the operator can access both types of information, but the operator experiences information overload and increased burden
Solution Approach 1:
The patent extracts and displays only the necessary sensor information on the head-mounted display rather than showing all available information. The control device determines which sensor data to display based on robot operation state, extracting only relevant information to avoid overload while maintaining completeness of necessary data.
Solution Approach 2:
The patent dynamically adjusts the displayed information based on the robot's operation state. The control device changes what sensor information is shown on the head-mounted display according to real-time operation conditions, making the information system adaptive rather than static, thus preventing information overload while ensuring necessary information is always available.
2Loss of information
If all sensor information is continuously displayed on the transparent display unit, then the operator has access to complete information, but the work efficiency decreases due to unnecessary information display
Solution Approach 1:
The control device extracts and displays only the sensor information that is currently necessary for the robot's operation. By filtering out unnecessary information while maintaining availability of complete sensor data, the system improves work efficiency without sacrificing information accessibility when needed.
Solution Approach 2:
The patent implements periodic updates of sensor information display based on operation phases. Rather than continuous display of all data, the system periodically refreshes and updates the relevant sensor information on the head-mounted display according to the robot's operational state, reducing visual clutter while maintaining information availability.
3Loss of information
If the transparent display unit displays comprehensive sensor information, then the operator can make informed decisions, but the operator's focus on the physical world is reduced
Solution Approach 1:
The control device extracts and displays only the critical sensor information needed for decision-making on the transparent display unit. By selecting and showing only essential data rather than comprehensive information, the system enables informed decisions while maintaining the operator's ability to focus on the physical workspace.
Solution Approach 2:
The patent applies local quality by displaying different types of sensor information in different locations or contexts on the display unit. Critical decision-making information is prominently displayed, while less important data is minimized or placed in secondary positions, allowing the operator to access comprehensive information while maintaining focus on key elements and the physical world.

AI summary
A robot system includes a user interface configured to receive an operational instruction from an operator, a robot installed in a workspace and configured to perform a series of works including a plurality of processes, a sensor installed in the workspace, a transparent type display unit configured so that the operator is visible of a physical real world and configured to display information detected by the sensor as the image screen, and a control device. The control device displays on the transparent type display unit, when the robot is operated by the user interface, first information that is information detected by the sensor, as the image screen.
