BIO-IMPEDANCE SENSING FOR GESTURE INPUT, OBJECT RECOGNITION, INTERACTION WITH PASSIVE USER INTERFACES, AND/OR USER IDENTIFICATION AND/OR AUTHENTICATION

原文（中国語）

This disclosure describes systems, apparatuses, and methods that utilize electric field sensing in an antenna topology. In some embodiments, the systems, apparatuses, and methods use a sensing modality, such as bio-impedance sensing, to detect and/or determine one or more user activities. The bio-impedance sensing can be used for held-object or touched-object recognition, gesture input recognition (e.g., recognition of one-handed gestures, two-handed gestures, etc.), user interface (UI) interaction by utilizing electrically passive components, and/or biometric identification and/or authentication.
