A non-contact gesture control method, used to control an electronic terminal device, wherein the method comprises: receiving a first gesture motion of a user, wherein the first gesture motion is not in contact with the electronic terminal device; obtaining, according to a pre-stored mapping relationship, a first control instruction corresponding to the first gesture motion, wherein the first control instruction is associated with a first operation to control the electronic terminal device so that the electronic terminal device performs an operation corresponding to the first control instruction; receiving a second input from the user within a preset delay period from receiving the first gesture motion; obtaining a second control instruction of the user, wherein the second control instruction is associated with a second operation to control the electronic terminal device; and comparing the first control instruction with the second control instruction, wherein if the first control instruction and second control instruction are the same, the electronic terminal device only performs the first operation once; and if the first control instruction and second control instruction are different, the electronic terminal device performs both the first operation and the second operation; wherein receiving the second input comprises either one of: receiving a first voice command of the user within the preset delay period; and obtaining, according to a pre-stored mapping relationship between a voice command and a control instruction, the second control instruction corresponding to the first voice command; receiving a first signal which shows lip motion of the user within the preset delay period; and obtaining, according to a pre-stored mapping relationship between a signal which shows lip motion and a control instruction, the second control instruction corresponding to the first signal which shows lip motion; and receiving a first brain wave signal of the user within the preset delay period; and obtaining, according to a pre-stored mapping relationship between a brain wave signal and a control instruction, the second control instruction corresponding to the first brain wave signal. receiving a first gesture motion of a user, wherein the first gesture motion is not in contact with the electronic terminal device; obtaining, according to a pre-stored mapping relationship, a first control instruction corresponding to the first gesture motion, wherein the first control instruction is associated with a first operation to control the electronic terminal device so that the electronic terminal device performs an operation corresponding to the first control instruction; receiving a second input from the user within a preset delay period from receiving the first gesture motion; obtaining a second control instruction of the user, wherein the second control instruction is associated with a second operation to control the electronic terminal device; and comparing the first control instruction with the second control instruction, wherein if the first control instruction and second control instruction are the same, the electronic terminal device only performs the first operation once; and if the first control instruction and second control instruction are different, the electronic terminal device performs both the first operation and the second operation; receiving a first voice command of the user within the preset delay period; and obtaining, according to a pre-stored mapping relationship between a voice command and a control instruction, the second control instruction corresponding to the first voice command; receiving a first signal which shows lip motion of the user within the preset delay period; and obtaining, according to a pre-stored mapping relationship between a signal which shows lip motion and a control instruction, the second control instruction corresponding to the first signal which shows lip motion; and receiving a first brain wave signal of the user within the preset delay period; and obtaining, according to a pre-stored mapping relationship between a brain wave signal and a control instruction, the second control instruction corresponding to the first brain wave signal.
