Here's one invention we all need. A voice activated air freshener! Japanese engineers did just that, and this creative prototype device is called "FragWrap" was designed by engineers at Keio University in Fujisawa, Japan according to New Scientist reported.

The video below shows how you can tell the robot what fragrance you'd like and it will listen to you and process the scent and blows it across the room in the form of a soap bubble. When the bubble bursts, smaller fans will spread the aroma out in different directions.

New Scientist reports that the researchers are going to demonstrate FragWrap at a ubiquitous computing conference in Switzerland later this year.

Yup. We do need this.
