The LHIPA (Low-High Index of Pupillary Activity) is a metric used in cognitive science and human-computer interaction to measure cognitive load based on fluctuations in pupil diameter. It helps researchers and developers analyze mental workload in tasks such as gaming, training simulations, and usability studies.
This asset provides an easy-to-use LHIPA calculation script for Unity. Simply provide a list of pupil diameter values and the duration of the measurement, and the tool will output the corresponding LHIPA value.
How is LHIPA used?
A higher LHIPA value indicates greater cognitive load, while a lower value suggests minimal effort or distraction. Typical values range between X and Y (example: 0.05 = low load, 0.25 = high load).
Key Features
- Plug & Play: Load the script in your scene and call the LHIPA function with pupil diameter data. LHIPA is computed automatically!
- Works across platforms: Suitable for desktop, mobile, and VR applications.
- Live & recorded data: Supports real-time calculation and post-processing of recorded eye-tracking data.
- Customizable settings
- Well-documented & example scenes: Includes two demo scenes for testing and integration examples.
