Abstract
A control method and an electronic device are described where the method includes acquiring a real-time collection image regarding a space operation area; according to the real-time collection image, determining whether a first finger and a second finger belonging to a same hand of a user are present in the space operation area; acquiring a first distance between a first fingertip portion of the first finger and a second fingertip portion of the second finger, and generating a first determination result according to the first distance; determining whether the first fingertip portion leaves the second fingertip portion along a direction away from the user's body or approaches the second fingertip portion along a direction approaching the user's body; acquiring a motion parameter of the first fingertip portion; and generating a control instruction according to the motion parameter of the first fingertip portion.
