If you follow the news constantly technical, you may be heard company Elliptic Labs before. For those who have not heard of this company before, they are a company that has launched ultrasound technology in 2014 so that the company used the ultrasound to allow users to interact with portable devices without the need to touch it at all.
Now, Elliptic Labs company returned to us this year with more waves of ultrasound technology, except that in this time can play a role in getting rid of the proximity sensors in the front end of the smart phones. In this case, in the case if you are wondering what those dark circles in the front of the smart our phones, regardless of the camera and speaker, it includes proximity sensors.
Proximity sensors in smart phones are used to screen off the phone when it is placed on the face during a call. However, Elliptic Labs company believes that ultrasound can replace the sensors, and the best part is that there will be no need for new hardware. Instead, it will rely on the loudspeaker and microphone in the smartphone.
Loudspeaker, will issue an ultrasound, and thanks to some software, will be discovered when ultrasound waves change, for example when they are close to it, and can then be assigned to the phone to turn off the screen. Unfortunately, we're not sure whether the companies will depend on the technology developed by the company Elliptic Labs, but the latter is now in talks with several hardware manufacturers.
