Benefits of technology

This technology helps identify different types of media that are harder or lighter than others based solely upon their accelerations during use without requiring expensive specialized devices like an oscillating motor for its operation. It uses spectral analysis techniques such as sonar imaging to analyze sounds from loudspeakers placed near it's mouth while playing music. By analyzing this data alone, we aimed at finding patterns where there was no other type of media more likely to be very difficult to break down compared to normal ones.

Problems solved by technology

The technical problem addressed in this patents relates to improving the efficiency and precision of analyzing sensor data from smart phones during navigation tasks like walking without worry about their battery life. This requires accurate identification of materials within the device's surroundings, which helps users identify them better.

Abstract

The invention discloses a method for detecting a type of a medium material of a part for receiving terminal equipment. The method comprises the following steps of A, by an acceleration sensor built in terminal equipment, acquiring a sampling value of an accelerated speed produced by terminal equipment vibration, carrying out spectral analysis of the sampling value of the accelerated speed, and determining hardness of a medium material of a part for receiving the terminal equipment according to the analysis result, and B, through a sound sensor built in the terminal equipment, carrying out sound spectrogram analysis, and distinguishing the medium materials having similar hardness according to the analysis result. The method can realize spectral analysis of the accelerated speed sampling value and the voice frequency sampling value only by the terminal equipment, can accurately determine the type of a medium material of the part for receiving the terminal equipment, adopts a simple calculation method, produces an accurate determination result, and has a strong practical meaning and a popularization value.
