Images projected on floor guide people at event sites and train stations

By Norio Matsumoto

Mitsubishi Electric Corp has started to test Dynamic Sign, which smoothly guides people by using a projector to project images such as animated arrows, characters and figures on the floor of a passageway.

The test was conducted at the Musashino Forest Sport Plaza in Chofu City, Tokyo.

The Dynamic Sign shows the direction of movement and guides people to an elevator, escalator, etc by using animation. It becomes possible to improve visibility by moving figures and illustrations, according to Mitsubishi Electric. In addition, displayed contents can be easily changed. So, it is possible to change traffic lines in accordance with the flow of actual people on the day of the event.

The Dynamic Sign is suited for (1) arenas where various events such as concerts and sports take place and traffic lines change each time and (2) public facilities such as train stations where the flow of people changes in accordance with time of day.

The projector set up at the test site is a commercially-available product of another company. In a case made by Mitsubishi Electric, the short-focus projector is stored. The case was installed in places where a passageway branches and where visitors easily get lost such as near stairs and escalators.

Moreover, a camera was placed near the case of the projector to verify the effects of the Dynamic Sign. Visitors' reactions to the Dynamic Sign and the directions of visitors' lines of sight are used for measurement.

Mitsubishi Electric is making efforts to make the Dynamic Sign an international standard. It already set up a working group in the International Organization for Standardization (ISO).

"We will standardize it in about three years," the company said in a statement.

Errr. Great when there is no one standing there, otherwise you are projecting this on peoples heads and casting a shadow.

I believe the white boxes in the photo are the projectors, which would mean they aren't on the ceiling. But the issue of peoples bodies blocking the image would still exist.

The only way to make this work would be if the floor itself generated the images. And even then, if the area was crowded people couldn't really see the floor/image.

Doesn't this present the same problems that stations now claim to be struggling against with people staring down at their cellphones while walking?
