Who Willed It?: Decreasing Frustration by Manipulating Perceived Control in BCI Games
Brain-Computer Interface (BCI) technology often suffers from low signal recognition rates, which frequently lead to user frustration and a diminished sense of agency during gameplay.
- Integrating fabricated system-generated inputs at rates between 15% and 30% significantly reduces user frustration and increases perceived agency in BCI games.
- Perceived control is driven primarily by the frequency of user input attempts rather than the ratio of genuine to fabricated successes.
- Fabricated input serves as a viable design framework to maintain user engagement and motivation in BCI applications despite low hardware signal recognition rates.

Evaluating the Onboarding Phase of Free-to-Play Mobile Games: A Mixed-Method Approach
High player churn during the initial onboarding phase represents a significant barrier to long-term retention and revenue generation within the free-to-play mobile gaming sector.
- The onboarding phase—defined as the period from first interaction until the completion of core game mechanics—is a critical determinant of player retention in free-to-play (F2P) mobile games due to high initial attrition rates.
- Physiological measures, specifically Galvanic Skin Response (GSR) and Heart Rate Variability (HRV) via photoplethysmogram (PPG) sensors, are effective tools for evaluating mobile game UX, providing objective data that correlates with player-reported experiences.
- Comparing designer-intended experience graphs against composite player-reported graphs reveals significant discrepancies, highlighting specific pain points such as lack of autonomy, excessive wait times, and challenging control schemes.
