There are spaces where it is necessary to pass or stop (i.e. entrance/exit, a bookshelf, a market stall) and where, therefore, it is very important to helps people to understand how to carefully navigate the space, minimizing interaction at risky bottlenecks. In these cases you can use this signal, which reminds you of a “forbidden sign” and increases attention, helping people to maintain the right caution.
We did not want people to queue back to front, we wanted them to look at each other, making safe interaction possible. Moreover, a linear queue requires a much larger space. The solution was written in the stars, more precisely, in the constellation. As we did for the other signs, the irregularity of the symbol helps people keeping a high level of attention.
This is the easiest solution to help people to stop and talk safely: squares (but they can also be simple painted points on the ground) inside which to stop and stay close enough. We suggest disposing of the regular grid pattern, instead using the different dimensions to help raise the level of attention. This method can be applied in many different ways, places and situations- we leave it up to you.
