Avoiding Pedestrians With the Help of Lasers

A concept for a safer crosswalk projects a virtual barrier to remind drivers where and when to stop

The theoretical design would project a virtual barrier in front of crosswalksHanyoung Lee

Hanyoung Lee wants you to be seen. The South Korea-based product designer devised a prototypical warning device to prevent pedestrian strikes along roadway crosswalks. It's called the Virtual Wall, a visual barrier created from plasma laser beams.

The system casts larger-than-life images of pedestrians in eye-grabbing red across the roadway, at a location where such peds are likely to be crossing.

We don't imagine the plasma lasers are the cutting type, however. We would never endorse a radical social engineering project that radical.
