摘要: The interaction between human and smart phones is mainly based on press buttons touch screens. As wireless charging power transfer (WPT) coils standardized becoming a competitive feature for in recent years, it also possible to control without contact by interacting with their coils. In this paper, non-contact method interact proposed investigated. A Colpitts oscillator built tested using standard WPT coil as part of the resonant tank elements. Experiment results show that frequency heavily influenced hand movement, which could be further interpreted phones. By analyzing changes multiple embedded into phone, determine movement performed user.
