Abstract

The present disclosure provides a touch panel surface touch recognition method for a touch control device. The method includes acquiring real-time user touch parameters of a user touch; using the acquired real-time user touch parameters to query a pre-established database and to obtain a user touch parameter range corresponding to the acquired real-time user touch parameters; and recognizing an overall touch type based on the user touch parameter range. The pre-established database stores relationship data between pre-configured user touch types and user touch parameter ranges corresponding to the pre-configured user touch types; and different user touch parameter ranges correspond to different pre-configured touch types.
