Towards a Common Language for Immersive Experiences: a Cross-Sector Exploration of Concepts and Measurement
How are IX effects measured? And do different sectors even mean the same thing when they use IX concepts and measurement methods? These questions keep evolving alongside developments in the IX field. For Zuyd University of Applied Sciences, this is reason enough to take a fresh, critical look at how existing concepts and methods are perceived — together with other research groups and IX creators from the creative industries.

May I ask you a question? A large-scale experiment examining the effectiveness of a multimodal, conversational digital dietitian on nutritional knowledge in virtual reality
Dietitians play a key role in healthcare, but a shortage of well-trained professionals is looming. Wageningen University & Research is therefore investigating an immersive digital dietitian: in VR, patients learn about portion sizes, energy density and food preparation by preparing virtual meals themselves. The central question is whether the virtual dietitian's conversational abilities and non-verbal communication - asking questions, gestures, facial expressions - further strengthen the learning effect.
The Good, the Bad, and the Ugly: Exploring the Potential of VR for Decolonial Storytelling
Public values are a key priority of the CIIIC funding programme. How do we ensure IX applications are developed, deployed and used responsibly? This theme runs through every funded project like a common thread. The project led by Inholland University of Applied Sciences (with partners including the National Archives and the National Library of the Netherlands) focuses entirely on public values. Its central question: how can scriptwriters responsibly develop cinematic VR stories about colonial histories and their continuing impact on society today?
ImmersiveValidMovement: Validatie van consumenten-XR voor verantwoorde fysiotherapie oefeningen
In physiotherapy, there is growing interest in using immersive experiences (IX), such as XR serious games, to motivate patients and help them perform exercises correctly. To this end, VerseUS Games has developed XR exercise formats that use the built-in sensors of consumer XR headsets (such as Meta Quest and Pico) to track patients' movements. However, it remains unclear how reliable and valid this data is for assessing clinically relevant joint angles, particularly in patients with complex shoulder complaints. ImmersiveValidMovement therefore focuses primarily on "new methodological approaches to measuring usability and effectiveness of IX". We are developing and validating methods to derive head, neck, shoulder and elbow movements from XR sensor data (headset and hand controllers) and to assess their reliability. We are not developing new IX software or hardware, but working with existing VerseUS games and consumer XR headsets. The focus is on measurement methods, analysis techniques and responsible use. In work package 1 (the first three months), we carry out the preparatory work. Together with physiotherapists (FlevoFysiotherapie), we specify which joint angles and variables are relevant for correctly performing the prescribed exercise (position, velocity, acceleration; within a global coordinate system and/or relative to body segments). VerseUS Games provides the XR environment and handles the technical work of exporting time-synchronised data collected from the headset. UMCG oversees the research protocol, arranges ethical approval, and provides the research labs needed to carry out the study. In work package 2, we then carry out the validation study, comparing the XR measurements against the gold standard (such as Vicon or Optotrak) available at UMCG. Reliability and validity are determined using methods including ICC, Bland–Altman plots, correlations and RMSE. Based on this research, UMCG will deliver a report on the validity and reliability of the VerseUS XR exercises, as measured by the sensors in commercial headsets. This report will form the basis for further development.
GausScape: Evaluating 3D Gaussian Splatting for Spatial Understanding in Greenhouse Environments
In greenhouse horticulture, operators need to monitor optimal growing conditions for crops. Wageningen University & Research (WUR), together with 2 SMEs, is investigating the following question: what desired and undesired effects does a specific 3D technique (Gaussian Splatting) have on operators' work processes, perception and decision-making, compared to the current technique? The insights from this research may also prove relevant to other sectors.
Responsible Immersive Support for Firefighter Retreat under Unreliable Spatial and Communication Information
Firefighters retreating from a building operate under extreme time pressure, poor visibility and high mental strain - precisely when positioning and communication can become unreliable. The University of Twente is researching how immersive systems can make this uncertainty visible and understandable, so that digital cues support decision-making without creating false confidence or adding to the user's mental load.
Staging collective VR experiences
Scalable — and therefore affordable — IX onboarding and social IX, as part of an optimal user experience, remain key challenges for the IX community. How can museums onboard visitors more effectively so that more of them can experience a functional IX? And how can they create a shared VR experience in the process? That's what the Amsterdam University of Applied Sciences will be researching, together with a museum and an IX developer.
