Embodiment Construction
[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0047] see figure 1 , the present invention provides a kind of evaluation method of tactile experience, the evaluation method of described tactile experience comprises:
[0048] Step S10: When the motor is vibrated by the excitation signal, obtain the acceleration of the normal vibration and the abnormal vibration of the motor; the positive vibration is the vibration in the desired direction of the motor vibration to produce the tactile experience; the abnorma...

The invention provides a tactile experience evaluation method and device and a storage medium. The tactile experience evaluation method comprises the steps of acquiring accelerations of positive vibration and abnormal vibration of a motor; calculating the positive vibration acceleration and the abnormal vibration acceleration to obtain a first frequency domain vibration quantity and a second frequency domain vibration quantity; respectively carrying out HSL weighting on the first frequency domain vibration quantity and the second frequency domain vibration quantity to obtain an HSL weighting result; amplifying the HSL weighting result and then carrying out power calculation to obtain main vibration power, abnormal vibration total power and residual vibration total power of positive vibration; and calculating to obtain an abnormal vibration index and a residual vibration index. According to the technical scheme provided by the invention, the evaluation of the tactile experience of the motor vibration is realized, the performance of the motor vibration, the quality of the signal excitation and the tactile experience effect are detected, the evaluation is objective, and the data usedfor evaluation and the subjective perception of the user tactile sense have relatively strong consistency.
Description
【Technical field】 [0001] The present invention relates to the technical field of tactile perception, in particular to an evaluation method, device and storage medium for tactile experience. 【Background technique】 [0002] With the rapid development of smart devices, various APPs provide a variety of applications, and motors, as vibration and tactile devices, are receiving more and more attention. The tactile experience provided by motors is currently evaluated in a single way in the industry, and most of them rely on human subjective evaluation. However, subjective evaluation is a matter of opinion, and different people often get different evaluations, or even opposite evaluations. In order to obtain a relatively objective subjective evaluation, a large number of test samples are often required, and careful and objective analysis is carried out. Similar to taking pictures, the DXOMARK evaluation benchmark is a trustworthy industry standard for image quality evaluation of c...
