Configural display design techniques considered at multiple levels of evaluation

Area of Science:

• Human-Computer Interaction
• Cognitive Systems Engineering
• Information Visualization

Background:

• Configural displays are crucial for complex data representation.
• Effective design and evaluation methodologies for these displays are essential.
• Previous research has explored various design elements in isolation.

Purpose of the Study:

• To investigate the impact of four design techniques on configural display performance.
• To evaluate display effectiveness across different task types (data probes vs. system control).
• To assess the generalizability of evaluation findings.

Main Methods:

• Four design techniques (bar graphs/extenders, scale markers/grids, color coding, digital values) were applied to a baseline configural display.
• Ten distinct display variations were created, including a composite display with all techniques.
• Two evaluation methods assessed performance on low-level data probes and system control/fault detection tasks.

Main Results:

• Three design techniques significantly enhanced performance on low-level data probes.
• A display with only digital values performed worst on control/fault detection tasks.
• The composite display, integrating all four techniques, demonstrated superior effectiveness across both evaluation levels.

Conclusions:

• Specific design techniques enhance configural display usability for different tasks.
• A multi-technique composite display offers the most significant performance benefits.
• Limited generalizability exists between different evaluation methodologies for display design.
