TSURU, YAMANASHI PREF. – A team of researchers at Shizuoka University is hitching a ride on Japan’s bullet train technology, aiming to transmit targeted advertising at high speeds.
Using a groundbreaking technique called high-speed suggestive particle mapping (HS-SPAM), the system relies on embedded arrays of microscopic LEDs that flash subliminal messages. The initial tests, conducted in 2015, confirmed that images could be effectively transmitted and recognized by viewers.
Not long after they released their research, the team was approached by JR Tokai about deploying its HS-SPAM tech as an advertising medium for next-generation magnetic levitation trains.
“While branded ads were considered profitable for slow-moving trains, they realized that the approach wouldn’t be very effective with maglevs, which can travel as fast as 600 km per hour,” said professor Tetsuto Hayakawa, leader of the project team at Shizuoka University. “Beside, plastering such iconic trains with Hello Kitty and Super Mario would be a bit tacky, don’t you think?”
Hayakawa’s research team took up the challenge of implementing the trailblazing technology for JR Tokai, which operates shinkansen trains between Tokyo and Shin-Osaka.
“It occurred to JR that when these very rapid maglev trains go whooshing past, they invariably grab people’s attention, even if only for two or three seconds,” said Hideo Mabataki, a graduate student of ophthalmology and member of the research team.”We had a breakthrough when a team member noticed how warning lights on emergency vehicles boost their visibility by alternating direct and reflected light.
“We basically miniaturize the process with arrays of light-emitting diodes in the visible spectrum, which flash and reflect every one four-thousandth of a second. The viewer’s optic nerve receptors receive double the stimuli of a camera flash. If done right, it’s remarkably effective for up to 30 characters.”

That's just kind of scary.
