In human–computer interaction for data entry screens, what term describes a brief on-screen message that guides the operator about which data should be entered next?

Introduction / Context:
Usable data entry interfaces clearly indicate to operators what information is required and in what format. Such cues reduce errors and speed up workflows. This question asks for the concise term used for those on-screen messages that request or cue specific input from users.

Given Data / Assumptions:

• The interface is interactive, asking the user to supply data.
• The message is brief and directive (e.g., ‘‘Enter Customer ID:’’).
• We are not describing security credentials or management systems.

Concept / Approach:

A prompt is a short instruction or cue presented by the system to indicate the next required input. Prompts can include validation hints (format, length) and are foundational in command-line shells, forms, and wizards. They are distinct from passwords (authentication data) and MIS (a management information system, not a message type).

Step-by-Step Solution:

Verification / Alternative check:

Common UI/UX guidelines use the term ‘‘prompt’’ for input requests; shell prompts (e.g., >) and form labels serve the same guidance role.

Why Other Options Are Wrong:

MIS: A system category, not a message.

Passwords: A credential, not an instruction.

Tactical: A planning adjective, not an HCI element.

None: Incorrect because ‘‘prompt’’ is the standard term.

Common Pitfalls:

Confusing placeholders or labels with prompts—though related, the prompt explicitly asks for input activity.

Final Answer:

prompt
