things that depend on you to ensure safe, efficient work and to protect
the equipment.

Part 2: What the Machine (Computer) Should Do
Principles for a UserFriendly System
These are the principles the system should follow to be user-friendly and effective
for the human.
1. Reliability and Availability
• Stability: The system should run stably without frequent crashes, freezes, or
fatal errors.
• Error Handling: If an error occurs, the program should suggest solutions or
recovery options, not just close.
• Accessibility: The system must be accessible to people with disabilities (support
for screen readers, full keyboard navigation, etc.).

Feedback

always in the same place).
3. System Security
• Data Protection: The computer must ensure the confidentiality and integrity of user data (e.g., through encryption and access controls).
• Updates: The system should receive regular updates to patch security vulnerabilities.
• Access Control: Provide tools for managing user permissions (e.g., Administrator, Standard User, Guest).

The Key Principle of Human-Computer Interaction
It is a dialogue, not a monologue.

actions, its current status, and any potential errors.
Successful interaction is based on:
When these rules are followed by both sides, working with a computer becomes comfortable, safe, and productive.
