Abstract

The invention discloses an object information identification method and system; the object comprises a controllable reflection unit; the controllable reflection unit has at least two different reflection states for a reflection light of a same incident light; the method is applied for an electronic device with a light sensor; the method comprises the following steps: emitting identification light to the controllable reflection unit; receiving the reflection light in a sensing area of the light sensor, and the reflection light is obtained by the controllable reflection unit through reflecting the identification light; obtaining the object information according to the reflection state of the reflection light and a preset code rule. The method and system can realize object information identification, and reduces power consumption of the electronic device.

Description

technical field [0001] The invention relates to the field of sensor control, in particular to an object information identification method and system. Background technique [0002] Nowadays, electronic devices have more and more functions. There are also more and more scenarios for data interaction between multiple electronic devices. Before data exchange between electronic devices, device identification is first required. [0003] In the prior art, methods for device identification mainly include Near Field Communication (Near Field Communication, NFC) technology and Radio Frequency Identification (Radio Frequency Identification, RFID) technology. Both of these two technologies need to transmit the identification information of the electronic device through wireless communication between the electronic devices that perform device identification. That is, at least one chip with wireless communication function needs to be activated. [0004] Since the identification method...
