The invention provides a detection method and a
content sharing method. When a
mobile phone and other devices are detected to be close to a display screen of a PC, a
tablet computer and other large-screen devices, rapid and accurate content interaction is achieved based on the close position, for example, the content of the position on the screen is shared to the
mobile phone or the content shared by the
mobile phone is displayed in the corresponding screen area, and the whole process is efficient and convenient to operate. In order to realize the approach detection, a hierarchical
capacitance detection technology is introduced, a half-Idle mode between an Idle (idle) mode and an Active (active) mode is additionally arranged for a display screen touch
integrated circuit (IC), and when specific events such as equipment unlocking occur, the IC is switched into the half-Idle mode to improve
capacitance data acquisition frequency, and whether equipment approaches or not is preliminarily detected; once approaching is detected, the IC is switched into an
Active mode to further improve the
capacitance data acquisition frequency and accurately detect the approaching position, and
content sharing is triggered accordingly, so that the high accuracy is guaranteed, and the equipment
power consumption is effectively considered.
