London, May 21 (IANS): This Japanese fan follows you around the room and turns itself off when you leave.
The 'Human-sensing Oscillating Fan' detects when a person is in range, to begin blowing them with air.
Equipped with an built-in infrared sensor, the $176 (Rs.10,000) fan ensures it blows air only towards people and not empty space, media reports said.
“It is able to turn up to 85 degrees and blast people with air, rather than other fans that turn and blow into an empty room. If it detects no-one within range for about a minute, it will shut down and stop blowing air,” said its Japanese manufacturer Iris Ohyama Inc in a statement.
It can also track multiple people; if it sees more than one person, it will take turns in pointing towards each of them.
The device also helps cut down on energy usage when it is not being used, Ohyama added.
