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 health care, but a shortage of well-trained professionals is looming. Wageningen University & Research is therefore exploring an immersive digital dietitian: in VR, patients learn about portions, 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.
