Comparing Text-based and Graphic User Interfaces for novice and expert users.

Area of Science:

• Human-Computer Interaction
• Usability Engineering
• Health Informatics

Background:

• Graphic User Interface (GUI) is often presumed superior to Text-based User Interface (TUI).
• Electronic dental record systems require efficient and user-friendly interfaces.
• Comparative usability studies are crucial for optimizing healthcare technology.

Purpose of the Study:

• To compare the usability and effectiveness of GUI and TUI in an electronic dental record system.
• To evaluate the impact of user expertise (novice vs. expert) on interface performance.
• To investigate potential learning transfer effects between GUI and TUI.

Main Methods:

• Utilized several usability analysis techniques to assess GUI and TUI.
• Employed a within-subject design to evaluate task completion time and steps.
• Assessed both novice and expert users' performance with each interface.

Main Results:

• GUI was not superior to TUI for expert users in terms of time and steps.
• GUI demonstrated better performance for novice users.
• Novice users exhibited a learning transfer effect from TUI to GUI.

Conclusions:

• The superiority of GUI over TUI is not absolute and depends on user expertise.
• Effective user interface design hinges on the alignment between the interface and specific user tasks.
• Task-interface mapping is a critical factor in determining user-friendliness, not the interface type alone.
