A pedestrian watched a smartphone video projected onto the ground in front of him.

The local was spotted using his high-tech smartphone while walking, with the phone's screen being displayed on the pavement in Henan, China, on November 25.

Footage shows motion graphics projected onto the flat surface, clear and visible, causing onlookers to be astonished as they witness the remarkable futuristic device.

Phones with built-in projectors use a small semiconductor laser or LED light source to project an image or video onto a surface. The image is focused and magnified by lenses and optical systems to ensure clarity. Some phones with built-in projectors also have speakers or audio output options.
