Why usability alone does not create a good experience
An interface can be clear, fast and error-free—and still leave people indifferent. Hassenzahl’s model explains why.

Can the way we look really reveal personality?
Ninety-one participants, multiple tasks and second-by-second measures tested what truly persists in gaze.

Does the Big Five really predict behavior?
Five dimensions capture an important part of personality. Their predictive power is also easy to overstate.

Adversarial attacks: the image barely changes, the prediction flips
Gradient-based methods, transfer and defenses: understanding a fundamental neural network weakness.

Does gaze always lead the mouse?
The cursor may follow gaze, lead it or remain still. Interface events are what make those lags interpretable.
- Attention
- Behavioral signals

Can user experience (UX) be measured without asking a question?
Explicit measures, implicit measures and triangulation: what we gain — and risk — when observing experience without a questionnaire.

What a heatmap hides in a user experience (UX) study
What spatial aggregation removes: order, transitions, revisits, task, time and individual differences.

How context changes study results
Why a robust measure should survive some context changes — and explain the others.

When the average user hides opposite reactions
One variant may energize some users and hinder others. Personality helps frame that variation without forcing people into rigid types.

How do you compare user insights without losing their context?
Four markets, multiple languages and inconsistent formats: one shared data contract turns fragmentation into traceable signals.

Each post separates findings, methodological limitations and possible uses. The primary sources are my publications, doctoral research and cited papers.
