Disclosed is an SSVEP brain electrical potential based wireless BCI input system, comprising an SSVEP keyboard and a brain electrical head strap. The SSVEP keyboard of the present invention is used to induce SSVEP brain electrical potential of a user, and comprises keys which can flash in a specific frequency, and masks which indicate key values can be replaced; and the brain electrical head strap comprises a brain electricity acquisition module, a brain electrical signal analysis module and a Bluetooth communication module, which are respectively used for acquiring a brain electrical signal of the user, identifying an SSVEP potential so as to judge the input intention of the user and transmitting a key value to a mobile smart device mating with same via Bluetooth. The brain electrical head strap is a portable wearable device, and can cooperate with the SSVEP keyboard to wirelessly control the mobile smart device. Provided is an approach for enabling direct interaction between the human brain and a mobile smart device, which can assist the activities of a patient who has lost the action ability but has sound thinking ability, and also provides a convenient control tool which can liberate both hands for healthy people.
