HOTKNOT BASED PROXIMITY DETECTION METHOD, APPARATUS AND TOUCH SCREEN TERMINAL

摘要

A proximity detection method and apparatus, and a touch screen terminal are provided. The method includes: sending a proximity detection sequence to a touch screen terminal; after the touch screen terminal determines that the proximity detection sequence is valid, receiving a proximity response sequence fed back by the touch screen terminal; and determining whether the proximity response sequence is valid according to signal strength of frequencies in the proximity response sequence and at least two preset signal strength thresholds, to determine whether the touch screen terminal approaches.

1. A proximity detection method, comprising:
sending a proximity detection sequence to a touch screen terminal, wherein the proximity detection sequence comprises at least two symbols modulated by using different frequencies; receiving a proximity response sequence fed back by the touch screen terminal, wherein symbols in the proximity response sequence are the same as those in the proximity detection sequence; and determining whether the proximity response sequence is valid according to signal strength of frequencies in the proximity response sequence and at least two preset signal strength thresholds, to determine whether the touch screen terminal approaches.
