The brainwave remote control device mainly includes a remote control device body, an acquisition module connected to the remote control device body, a filter module, a motion sensor module, a signal processing module and a Bluetooth module arranged inside the remote control device body. The acquisition module includes an elastic support arm and an EEG sensor probe installed at the end of the elastic support arm. The contact on the EEG sensor probe fits the user's scalp to collect brainwave signals.

[0018] Specific examples are given below.
