A primary goal of extended reality (XR) technologies, like VR, is to create relevant and engaging user experiences. However, humans are different, and they typically do not experience XR content in the same way. How can we know what users find relevant and engaging?

By investigating how humans perceive and experience – physical and virtual – environments, neuroscientists and psychologists have identified bodily measures (e.g., of heart activity) that provide information about cognitive and emotional functioning during an event or experience.

The aim of this project is to create the Excite-O-Meter, a user-friendly Unity plugin for XR creators to integrate physiological user information in the development and evaluation of XR content. Specifically, it will allow to record, analyses and visualize scientifically validated metrics of heart activity during XR experiences.

The Excite-O-Meter is supported by XR4ALL and the European Commission.
