Abstract
The navigation of urban environments by blind adults and children is a complex activity. While research on blind people’s navigation has often focused on assistive technologies, less attention has been given to the embodied nature of their daily walking experiences. In this study, we apply chromatic recurrence-based analysis to characterise the joint walking dynamics of a blind mother–child dyad and explore their behaviour in different acoustic contexts. Video-recorded sessions were coded, and their walking behaviour was characterised across different acoustic environments. Results showed that mother and child exhibited spontaneous synchronisation of their steps. Recurrence analysis indicated that the synchronous walking intervals were shorter and more predictable, whereas asynchronous walking was longer and less predictable. This case study suggests a flexible use of synchronisation and non-synchronisation patterns in a system of unstable coordination that is open to environmental contingencies.
