Faster And Touchless Ultrasonic Gesturing For Mobile Devices

Posted March 4, 2015

Eliptic Labs announced (at Mobile World Congress 2015) ultrasonic gesture technology, which has a remarkably large field of response for touchless gesturing. These breakthroughs enables mobile devices to deliver the fastest, most natural and easiest interface to interact with.


Ultrasound signals sent through the air from speakers integrated in smart phones and tablets bounce against your hand and are recorded by microphones also integrated in these devices. In this way, technology recognizes your hand gestures, very similar to how bats use echolocation to navigate.


The technology works further away from the screen, at up to two meters and 180 degrees around the screen, allowing devices to respond in a fraction of a second after a gesture command. This technology could appeal to consumers who are taking pictures and snapping selfies where photos can be taken with a quick gesture several feet away from the subject. The technology also gives users a more flexible way to record videos without the need to touch the phone for starting and stopping. Gaming on mobile devices should become more accurate, immediate and fun.


These latest advances build on the recently launched Multi-Layer Interaction (MLI) capability. Without touching the device, as your hand moves towards your phone, for example, the screen lights up and information is displayed. As you continue to move your hand closer, different information is revealed. MLI makes it faster to work with applications you use repeatedly during the day, such as checking messages, playing games, navigating maps, using social media, and watching videos.

With the Elliptic Labs PDK (Prototype Development Kit), you can build your own applications and demonstrate touchless gesture recognition on your current or future smartphones. You only need a USB gesture driver to support Elliptic Labs’ PDK. The source code will be provided to help you compile the driver into your device kernel.
