Abstract: Precise analysis and description of movement and gestures by a human or other object are carried out by a computing device assisted by camera and distance sensors. The same gestures and movements of an object in different locations and in different orientations may be identified according to coordinates and offsets applied to coordinates, and gesture-making areas projected so as to surround the object. The techniques can accurately identify actions of movements of the human or other object.

Abstract: A method for logging into a number of applications of an electronic device includes obtaining a login facial image of a user when the user opens a first application of the number of applications, determining whether the login facial image matches a preset facial image stored in the electronic device, and logging into the first application when the login facial image matches the preset facial image. The preset facial image is linked to each of the number of applications. The electronic device automatically logs into the rest of the applications when the rest of the applications are opened, after the login facial image matches the preset facial image to log into the first application.
