An electronic device predicts a target key on a soft keyboard for selection by a user and enlarges the target key to make it easier for the user to select the target key. The electronic device includes a display that displays a cursor and keys that constitute a soft keyboard and a cursor control device for controlling movement of the cursor on the display. The electronic device further includes a processor operable to receive a cursor control signal representing movement of the cursor on the display from the cursor control device. In response to the cursor control signal, the processor predicts one of the keys likely to be next selected as the target key and enlarges the target key relative to other keys on the display.

The invention provides a keypress behavior pattern construction and analysis system of a touch screen user and an identity recognition method thereof. According to the invention, data analysis is performed by using history keypress information of inputting a password by a soft keyboard on a mobile phone touch screen; a corresponding neural network model is established; and model calculation is performed on new to-be-tested data, to recognize a user identity. The system comprises a user data acquisition module, a data pre-processing module, a model training module, and a user identity identification module. The user data acquisition module is responsible for acquiring time series information of a user clicking the soft keyboard and inputting the password, and pressure and contact area information. The data pre-processing module is responsible for pre-processing the acquired data, removing dirty data, and performing normalization on the data. The model training module is responsible for performing analysis and modeling on a key-in mode of all users. The user identity identification module is responsible for performing model calculation on the new to-be-tested data, to recognize the user identity and improve security of a user account password.

The invention discloses a controls distribution adjustment method and device and belongs to the field of soft keyboards. The method includes: receiving a command to edit controls; adjusting attributes of the controls according to attribute of a custom area to make sure that the sum of areas of the controls adjusted is equal to that of the custom area and that the shape of combination of the controls combined according to post-adjustment positions matches with that of the custom area; filling the custom area with the adjusted controls according to the post-adjustment positions. By filling the custom area with the controls, solved is the problem that after a dial pad area is narrowed and moved to the single side of a screen, far areas, which users find it difficult to touch with single hands, may still occur in the narrowed dial pad area due to the users possibly having hands of different sizes, and meanwhile inconvenience in inputting causes low inputting efficiency; inputting efficiency is improved.
