Games User Research
By measuring skin conductivity, you get access to the purest form of play experience.
According to the state-of-the-art research* surrounding player psychology, experience and game design, user experience (UX) in games is formed through interactions with individual elements within a game, e.g. finding a treasure box, fighting enemies. The key to understanding UX to drive innovation and user-centricity lies in these elements.
Natali’s project looks isolated at player’s biometric feedback as a result of interacting with a game’s individual elements. She choose to measure player’s skin conductivity using electrodermal activity (EDA) devices because it unlocks access to the purest form of play experience.
The purest form of an UX occurs as a bodily reaction before users can apply meaning to their experience. While this presents researchers with the debate of validity of such reactions, it also generates UX reactions free from any biases. It limits player or facilitator interpretation biases, presents fact based, objective measurements, and it’s industry standardized measurement of UX.
The project is located at the heart of Transversal Translational Medicine (TTM) and practical User Research borrowing research insights from neurosciences. Supervised by Prof. Dr. Thomas Günther, the project seeks to expand current research findings on the sympathetic nervous system (SNS), biometrics, and UX by driving and delivering game design innovation, and advocating a user-centric design.
Research Question
Hypothesis
Which elements impact skin response?
Player interaction with distinct game elements leads to specific, psychophysiological changes in their skin response.

Mixed Methods – Research Plan v.0.1
The project is located at the heart of Transversal Translational Medicine (TTM) and practical User Research borrowing research insights from neurosciences. Supervised by Prof. Dr. Thomas Günther, the project seeks to expand current research findings on the sympathetic nervous system (SNS), biometrics, and UX by driving and delivering game design innovation, and advocating a user-centric design.
Phase 2 (ca. 2023-2024) is about gathering user data, computing the data, and prototyping the first model, before going into the first audience review.
Analysis Plan v.0.1
The data analysis plan is to use linear regression and machine learning for data validation, due to the high number of independent variables. Details will follow soon.
