ISO 9241-303 Display Requirements for Robot Interfaces
The International Organization for Standardization (ISO) has developed ISO 9241, a series of standards that address human-centered design and usability in IT systems. Among these is ISO 9241-303, which specifically focuses on the display requirements for robot interfaces to ensure they are safe, user-friendly, and efficient.
This standard plays a crucial role in enhancing human–robot interaction (HRI) by setting guidelines that promote effective communication between humans and robots. By adhering to these standards, manufacturers can design systems that enhance productivity while minimizing risks associated with robotic interfaces. The requirements outlined in ISO 9241-303 are essential for the development of advanced robotics used in various sectors including manufacturing, healthcare, and service industries.
The standard addresses several key aspects to ensure usability:
- Legibility: Ensuring that all elements on the display are easily readable under typical conditions of use. This includes factors like contrast, size, and color choices.
- Contrast is critical for visibility; high contrast between text and background improves readability, especially in low-light environments.
- The size of characters should be appropriate to the distance at which they will be viewed. Typically, legibility requires a minimum character height that can vary based on viewing distance.
- Visibility: Ensuring that all elements are visible under typical lighting conditions and from common angles of view.
- This includes considering environmental factors such as ambient light, which can significantly affect visibility. Designers must account for these variables to ensure displays remain legible in various settings.
- Angle considerations are also important; displays should be designed so that they remain visible when viewed from common angles of use, including those with limited head movement.
The standard emphasizes the importance of consistency and clarity in display design. This includes:
- Consistency in layout: Ensuring that similar functions are consistently represented across different interfaces to reduce cognitive load.
- Clarity of information: Providing clear, concise, and unambiguous information about the robot's state and actions. This helps users understand what the robot is doing and how it can be controlled.
Incorporating these requirements into robotics design enhances safety and effectiveness by:
- Reducing errors in operation, which could lead to accidents or malfunctions.
- Making the robot more accessible and approachable for users with varying levels of expertise.
- Improving efficiency through intuitive design that minimizes learning time and effort.
