The present invention relates to a character input apparatus and method which pairs the title of a heading to the region where a character is inputted and determines the character group which can be inputted into the region corresponding to the heading as input candidate characters. When a character is inputted in the region, the heading in that region is discriminated and the characters are recognized referring to the input candidate character group corresponding to the title of the heading.

Method and apparatus for recognizing input handwritten characters

An information processing apparatus and method which performs character recognition based on a character pattern inputted in a form of a handwritten character or coordinate data. A sample character registration unit stores feature data of a sample character pattern, and a feature extraction unit obtains feature information of the input character pattern from the input coordinate data by FFT. The coordinate data representing the input character pattern and the sample character pattern registered in the sample character registration unit are compared, and a sample character corresponding to the input character pattern is recognized. The sample character pattern is transformed and displayed in accordance with the characteristic of the input character pattern based on the feature information from the feature extraction unit.

Sound waves from a plate-shaped acoustic source, which generates fundamental waves (sound waves) having at least two frequencies, propagate through a propagating portion. The propagating portion consists of a medium in which a non-linear interaction is induced by the fundamental waves. A secondary sound wave having a frequency conforming to the difference between the two fundamental waves is generated by the medium. Fundamental wave components other than the secondary sound wave are absorbed by an acoustic absorber so that only the secondary sound wave is delivered as an output. The acoustic source, propagating portion and acoustic absorber are substantially transparent and stacked in three layers. This allows the resulting acoustic output device to be incorporated in the display unit of an electronic apparatus.
