Abstract: A text input method and apparatus based on a virtual keyboard are provided, which relate to the field of human-computer interaction, and resolve a problem of how to complete text input based on the virtual keyboard. The method includes an electronic device that detects key points of a first hand based on an image including the first hand after obtaining the image including the first hand, and projects a virtual keyboard on the first hand based on the key points of the first hand. Further, after obtaining an image including the first hand and a finger of a second hand, the electronic device identifies, based on the image including the first hand and the finger of the second hand, a contact state or a pressing state between the finger of the second hand and the first hand.
