Knock it with a SmartPhone to Identify

Here a system built in South Korea that lets you knock on an object with a smartphone, and it identifies it using sound and motion sensors.   We worked on problems that predicted maintenance needs of machinery, using sounds and vibrations, might this be useful for such an application as well?  Another way to gather data that might be useful otherwise.     Add visual inspection information for machinery diagnosis?

Object Identification, Interaction with a Smartphone Knock
KAIST - South Korea

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in South Korea have developed technology for identifying objects and carrying out actions, simply by knocking on objects with a smartphone. The Knocker solution combines the sound and motion sensors in smartphones with software that executes directions according to sounds and vibrations. These capabilities are maintained even in low-light settings, without the use of cameras or other specialized hardware. Knocker harnesses the smartphone's built-in sensors, and machine learning identifies objects the device is knocked on by analyzing the responses generated when a smartphone is knocked against an object. Knocker was able to identify 23 everyday objects in noisy environments with 83% accuracy, and with 98% accuracy in quiet indoor environments.  ... "
