Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a music modulation processing method for modular force-sense interactive devices, which can modulate and process music signals, and output signals that drive different modules of multi-module force-sense interactive devices, thereby solving existing problems. The signal processing method can only output a single force sense control signal, and the force sense is single, which cannot well satisfy the user experience problem

Abstract

The invention discloses a music modulation processing method used for modularized haptic interaction equipment and belongs to the field of driving of haptic interaction equipment. The method includes receiving audio digital signals; performing signal extraction processing on the audio digital signals to acquire sampling digital signals; performing separation processing on the sampling digital signals; if separation signals are acquired after separation processing, outputting the separation signals to a corresponding module of the modularized haptic interaction equipment. By subjecting the audio digital signals to signal extraction processing, resampling of music signals is realized, and signals after sampling are ensured to be closer to original audio signals and not to lack fidelity; after the sampling digital signals are separated through separation processing, signals driving modules of the modularized haptic interaction equipment can be correctly output, outputting of different vibration senses and force senses can be realized, and experience effect of users can be improved furthest.

Description

technical field [0001] The invention relates to the field of control of force-sense interaction devices, in particular to a music modulation processing method for modular force-sense interaction devices. Background technique [0002] In the past 10 years, the application of haptic technology to mobile devices has been a hot topic. For example, Poupyrev et al. developed a high-performance haptic device called Touch Engine, which uses multilayer piezoelectric ceramics to provide rich vibration tactile feedback. However, force-sense interaction devices based on piezoelectric ceramics are expensive, and only one module can work, and cannot output diversified force senses. [0003] Inwook Hwang led a study that introduced a dual-band haptic mobile music device that can generate synchronous vibrotactile sensations in real time. The haptic mobile music device uses a new miniature dual-mode driver that can generate the two main frequencies required for vibration and runs a real-ti...
