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.

Abstract: The present invention discloses a CSFB handover method and apparatus, and a base station, and belongs to the communications field. The method includes: receiving, by an base station, a CSFB indication; sending, by the base station after receiving the CSFB indication, a measurement control message to user equipment, where the measurement control message is used to instruct the user equipment to measure cell signal quality and send a corresponding event measurement report; and according to a receiving status of the event measurement report sent by the user equipment, selecting, by the base station, to complete CSFB handover by using blind handover, or selecting to complete CSFB handover by using measurement-based handover. In the present invention, according to a receiving status of an event measurement report sent by user equipment, blind handover is selected or measurement-based handover is selected to complete CSFB handover, thereby increasing a CSFB handover success probability.
