Abstract
Disclosed is a device and method for inputting characters or drawings on a mobile terminal using a virtual screen. To input characters or drawings through a virtual screen, the mobile terminal includes an electronic pen, a virtual screen generator, a position detector for detecting the electronic pen position, and a character recognition algorithm for recognizing a trail as a character. When a signal is input from the electronic pen, the mobile terminal detects the originating position of the signal and its trail. The mobile terminal recognizes the detected trail as a character and generates a virtual screen with the recognized character.
Claims41
A device for inputting characters or drawings on a mobile terminal, comprising:
- a user input means for sending input signals;
- a virtual screen generator for generating a virtual screen;
- a position detector for detecting originating positions of the input signals on the virtual screen;
- and
- a control section for detecting trails corresponding to the originating positions of the input signals, outputting the detected trails to a preview window and storing trail information.
A method for inputting characters or symbols on a mobile terminal, which comprises the steps of:
- generating a virtual word screen for inputting characters or symbols through a user input means sending input signals;
- when input signals are received, detecting originating positions of the input signals;
- detecting trails corresponding to the originating positions of the input signals;
- recognizing the trails as characters or symbols;
- and
- outputting the recognized characters or symbols to the virtual word screen.
A method for inputting a drawing on a mobile terminal, which comprises the steps of:
- generating a virtual drawing board for inputting a drawing through a user input means sending input signals;
- when input signals are received, detecting originating positions of the input signals;
- detecting trails corresponding to the originating positions of the input signals;
- recognizing the trails corresponding to the originating positions;
- and
- outputting the recognized trails to the virtual drawing board.
