(Quintero et al., 2021) user-friendly open-source Unity plugin for XR creators to integrate physiological user information in the development and evaluation of immersive content. Specifically, it allows to record, analyze, and visualize metrics, for example, of heart activity using wearables (e.g., the Polar H10 chest strap) and of movement (e.g., trajectories) from VR devices using LabStreamingLayer.

(Fourcade, Malandrone et al., 2024)The AffectTracker is a tool which allows users to continuously track and record moment-by-moment ratings of valence and arousal (i.e., pleasantness and intensity of feelings) in Unity. With the help of an VR input device, users indicate their affective state by positioning a cursor in the valence-arousal space of the affect grid and receive customizable real-time visual feedback.

xai4mri is designed for advanced MRI analysis combining deep learning with explainable A.I. (XAI). It offers the following key functionalities:
-
Data Integration: Effortlessly import new MRI datasets and apply the models to generate accurate predictions.
-
Model Loading: Load (pretrained) 3D-convolutional neural network models tailored for MRI predictions.
-
Interpretation Tools: Utilize analyzer tools, such as Layer-wise Relevance Propagation (LRP), to interpret model predictions through intuitive heatmaps.
With
xai4mri, you can complement your MRI analysis pipeline, ensuring precise predictions and insightful interpretations.

Open stimuli
An open set of standardized and validated 3D household objects for virtual reality-based research, assessment, and therapy.
(Tromp et al., 2020)
Open data
Publicly available dataset of 228 healthy participants comprising a young (N=154, 25.1±3.1 years, range 20–35 years, 45 female) and an elderly group (N=74, 67.6±4.7 years, range 59–77 years, 37 female) acquired cross-sectionally in Leipzig, Germany, between 2013 and 2015 to study mind-body-emotion interactions. During a two-day assessment, participants completed MRI at 3 Tesla (resting-state fMRI, quantitative T1 (MP2RAGE), T2-weighted, FLAIR, SWI/QSM, DWI) and a 62-channel EEG experiment at rest. During task-free resting-state fMRI, cardiovascular measures (blood pressure, heart rate, pulse, respiration) were continuously acquired. Anthropometrics, blood samples, and urine drug tests were obtained. Psychiatric symptoms were identified with Standardized Clinical Interview for DSM IV (SCID-I), Hamilton Depression Scale, and Borderline Symptoms List. Psychological assessment comprised 6 cognitive tests as well as 21 questionnaires related to emotional behavior, personality traits and tendencies, eating behavior, and addictive behavior. We provide information on study design, methods, and details of the data in our dataset descriptor paper.
Data and scripts from individual studies
Please note that we’re currently standardizing our pipelines for cardiac and respiratory data - we will release a set of notebooks for ECG preprocessing and analysis in Q1/2025.
