The proximity sensors could be removed from our phones. Smart phone creators are passionate about making their equipment slimmer, and the Norwegian firm Elliptic Labs came up with its ingenuous way to push the limits even further.
Their idea is to eliminate entirely the proximity receptors in our mobile phones (meaning the ever present black spots above the gadget’s display). Instead, the company’s experts say that they created a smart program that uses the cell phone’s current speaker and mic to perform the same audio tasks.
In simple words, the mobile device’s speakers can work like the bats’ mouths and release sounds at various sound frequencies (here we are talking about wavelengths between 23 kHz and 35 kHz). These would make a phone’s mic work very similar to a bat’s ear, listening how our mouths, hands or other factors change these inaudible sounds.
The job of decoding that moving sounds cape is performed by the application (the company named it “Beauty”) that decides when an object gets too near and makes the display to turn off. If the company’s name seems familiar to some users, it is because the form has tried to integrate its ultrasound system into cellular phones and laptop computers for many years.
Recently, they traveled to Spain’s capital for the MWC event in 2015 to prove how easily cellular phones with the proper emitting or receiving components can react to hand movements up to 6 feet away. The response, as confirmed by some video clips, is very fast, but this time, Elliptic’s objective was to remove hardware from smart phones, not to add them.
People should not expect their next mobile device to get considerably smaller thanks to this method; the pieces that are included in proximity sensors are not large in the first place. Elliptic Labs’ experts say that these are usually just around 2×2 mm, since mobile devices are built like a jigsaw puzzle.
Freeing up this little area may lead to gadget dimensions that are more compact or the inclusion of other useful hardware. And more significantly, the lower number of components means that it is simpler to squeeze the new technology into new gadgets at range.
That is an important thing for a little start-up project and less effort for the smart phone creators who are constantly looking for different and better ways to do their job. The company’s representatives says that several (although unnamed) OEMs take into consideration applying Elliptic Labs’ strategy in their future gadgets, but users will soon notice how many phone producers really stick to their promises.
