The first individual practice of a soundwalk took place in The Hague in November 2021. Approximately ten people participated in the soundwalk, taking turns using the first prototype headset during a walk that took roughly half an hour.
The four locations, for which the sound processes were pre-designed, were marked on the map that the participants were familiarized with prior to the soundwalk. Each participant could switch between the sound processes by using the GUI on the phone.
