In recent years, gait analysis has increasingly shifted its focus toward real-world observations, which allow for a more comprehensive evaluation of individual motor performance. However, the influence of daily-life activities on such performance, and the consequent cognitive load, are still scarcely investigated. To address this gap, this study aims to investigate differences in gait parameters based on the activities performed in real-world conditions. Considering that navigation in real-world environments requires significant exploratory trunk and head movements to manage multiple concurrent visual and auditory stimuli, this work also includes the quantitative observation of head, trunk, and lower back movements. A total of 11 young adults (60% females, 20-31 years) wore a multi-sensor system, including pressure insoles, distance sensors and 5 magneto-inertial measurement units positioned on the head, chest, lower back, and feet (100 Hz), along with smart glasses for video recording.
