Embodiment approach
[0024] figure 1 It is a flowchart showing the steps of the input method based on facial expression recognition according to the present embodiment.
[0025] like figure 1 As shown, the input method based on expression recognition according to this embodiment can be roughly divided into four modules, which are subdivided into eight steps, wherein step S1010 constitutes an image acquisition module 101, and steps S1020-S1040 constitute an expression recognition and classification module 102, Steps S1050-S1070 constitute the input result matching module 103, and step S1080 constitutes the input module. The specific steps are as follows.
[0026] In step S1010, after the input method is activated, the user's face is photographed by the camera device and image signals are collected at fixed time intervals Δt, for example, at 0.1 second intervals. Among them, the camera device is installed on the user-operated device, or as an independent device.
[0027] Next, in step S1020, the...
