As part of a concept development project in collaboration with LEGO, I helped design a biometric-based usability testing setup for children aged 8–9. Our goal was to explore non-intrusive ways to capture emotional responses during gameplay using EEG and facial expression analysis

My role included research into biometric technology, ideation, prototyping, and facilitating user testing with children. We developed a headset prototype combining EEG sensors with a familiar gaming accessory to reduce interference during testing, and validated our concept through real-world testing at a local school.
