Backed by Science
A seamless user experience for high-stakes examiners is crucial. That's why Crucible is designed with visual ergonomics—a multidisciplinary science dedicated to understanding human visual cognition and interactions with system elements.
Crucible embodies scientifically valid psychological principles, such as:
- Gestalt Law: Humans perceive visual elements as whole patterns rather than separate components.
- Prägnanz Law (Law of Simplicity): People perceive and interpret complex images as the simplest form possible.
- Weber's Law: The smallest noticeable difference in a stimulus is a constant proportion of the original stimulus.
- Fechner's Law: The perceived intensity of a stimulus increases logarithmically with its actual intensity.
- Hick-Hyman Law: Decision-making time increases with the number and complexity of choices.
- Miller's Law of Short Term Memory Load: The capacity of short-term memory is limited, impacting the number of items people can retain and process at one time.
- Fitts' Law: The time required to move to and click on a target depends on the target's size and distance.
- Nielsen's Response Time Limits Law: Optimal user experience requires specific response times to maintain user engagement and efficiency.
- Pareto's Law (80/20 rule): Approximately 80% of effects come from 20% of causes; focus is on key functionalities that deliver the most value.
- Zipf's Law: The frequency of an item's occurrence is inversely proportional to its rank; frequently used features are prioritized for quick access.
Bias Mitigation
Cognitive biases are tendencies to think in certain ways that can lead to systematic deviations from a set standard of rationality or good judgment. Crucible mitigates such biases through careful analysis, research, and testing. The interface, practices, and measurements are constantly evolving, but Crucible takes a balanced approach across a wide variety of biases.
