Abstract: This application discloses a gesture-based manipulation method and a terminal device. The method includes: displaying a target picture, where the target picture includes a virtual object to be manipulated by using a detected gesture or a detected hand action; obtaining F sets of hand images; recognizing locations of hand knuckles on hands in the F sets of hand images based on the F sets of hand images, to obtain spatial locations of F groups of hand knuckles, where spatial locations of any group of hand knuckles are spatial locations of hand knuckles on a hand in a set of hand images, and F is an integer greater than 0; and performing, based on the spatial locations of the F groups of hand knuckles, a control operation corresponding to the spatial locations of the F groups of hand knuckles.
