Abstract: A method, an apparatus, a device and a computer-readable storage medium for recognizing aerial handwriting are provided. The method may include detecting a palm region of a user in a two-dimensional grayscale image; detecting a fingertip in the two-dimensional gray-scale image based on the palm area; determining a spatial trajectory of the fingertip based on a set of two-dimensional gray-scale images, the set of two-dimensional gray-scale images including the two-dimensional gray-scale image; and recognizing handwritten content of the user based on the spatial trajectory. A two-dimensional gray-scale image is used to recognize and track the spatial trajectory of the fingertip, which may speed up aerial handwriting recognition, and has low processing performance requirements for the device, while also ensuring high accuracy.

Abstract: The present disclosure provides a method and device for waking up a voice recognition function in a mobile terminal. The method includes: receiving a trigger instruction of an input interface, and activating the input interface; acquiring a rotation angle of the mobile terminal in a first rotation direction with an x-axis as a rotation axis, in which the x-axis is a widthwise direction of a screen of the mobile terminal; and activating the voice recognition function when the rotation angle of the mobile terminal in the first rotation direction with the x-axis as the rotation axis is greater than or equal to a first trigger threshold.

Abstract: The present disclosure discloses a method and apparatus for generating a candidate reply message. A specific embodiment of the method comprises: acquiring a text message of a currently received conversation; determining whether a pre-established conversation template matching the text message exists; and generating, in response to determining a conversation template matching the text message existing, a candidate reply message on the basis of the conversation template. According to the method provided by embodiments of the present disclosure, when the text message of the currently received conversation matches the pre-established conversation template, the candidate reply message is automatically generated, and a user may click the candidate reply message for reply, so that the time for the user to edit a reply message is saved, a period for the user to communicate with others is reduced, and the communication efficiency is improved.
