it’s meant for the blind but you can also hear it

The commodity of signalisation in public space is relying on covering more than one sense per information. Most of the pavement design is determined by the tactile information set in stones. The ticking devices installed on traffic lights poles to help blind people safely cross the street are one of those glazing layers on the functionality of our public space. All these are also perceivable by people with no vision impairments and probably often used by them. How really safe is this environment and how misleading all this information can get? What happens when you take the devices in your own hands and add misinformation?

it’s meant for the blind… was developed during the ‘bbb’ thematic project at the media design master programme, piet zwart institute, rotterdam.
