摘要:
A coordinate input apparatus includes a vibration pen, a vibration transmission plate, a plurality of vibration detecting units, a calculating unit, a memory unit, and a control unit. The calculating unit calculates vibration transmission times from a point designated by the vibration pen to the vibration detecting units, and calculates coordinate values of the designated point of the vibration pen. The memory unit stores the vibration transmission times from a first designated point of the vibration pen on the vibration transmission plate to the vibration detecting units and coordinate values of the first designated point. The control unit performs calculations on the basis of vibration transmission times from a second designated point calculated by the calculating unit to the vibration detecting units, the vibration transmission times from the first designated point and the coordinate values of the first designated point stored in the memory unit, thereby calculating coordinate values of the second designated point.

A vibration which is input to a vibration propagating plate by a vibration pen is detected by vibration sensors attached at corner positions of the plate. This vibration is propagated as elastic waves in the vibration propagating plate and reaches the sensors. The coordinates of the vibration input point are calculated on the basis of the vibration propagating times corresponding to the detection signals from the sensors. The vibration sensors are come into pressure contact with the vibration propagating plate through a fluid like a grease having a high viscosity or consistency. Since such a fluid is filled in the space which is formed between the pressure contacting surfaces of the vibrator and vibration propagating plate, their coupling states are stable and the vibration and coordinates detecting characteristics can be uniformed every product.

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.

A coordinate input apparatus in which by indicating a desired position on a coordinate input surface by an input pen, coordinate value data of the indicated position is detected and output, includes: an output device to output the coordinate value data; a detector for detecting the down state of the input pen; a memory for storing the coordinate value data detected after the elapse of a predetermined time from the detection of the pen-down state by detector; and a controller for allowing the coordinate value data stored in the memory to be output by the output device such as a liquid crystal display. With the apparatus, the fluctuations of the coordinate value data just after the pen-down operation and just before the pen-up operation can be eliminated and the stable coordinate value data can be always output. An erroneous detection due to the fluctuation of the coordinate value data upon coordinate input can be prevented.
摘要:
A coordinate input device interpolates sampling data, using less input data and simpler computing. The input data (coordinate information indicative of an input trace) are sampled both with a predetermined cycle (Tn), and at the end of a predetermined time interval after the sampling of the cycle Tn is complete. As a result of the two different samplings, not only the coordinate point determined by the sampling of cycle Tn, but also information indicative of a tangent vector at each coordinate point on the input trace are obtained. The coordinate point and the associated tangent vector information are thus output, so that a trace more faithful to the input trace is obtained using fewer coordinate points.

An information inputting method, as well as an information inputting device, extracts effective characteristic points from inputted stroke information and outputs coordinate information relating to the extracted characteristic points. First point coordinates values are input in a sampling cycle at a predetermined sampling rate. Second point coordinates values are input in the sampling cycle delayed a predetermined time behind the inputting of the first point coordinate values. A first vector is formed based on the first and second point coordinate values. First and second point coordinate values are also input in the subsequent sampling cycle, and a second vector is determined based thereon. The first point coordinate values inputted earlier are selected when these values cause the angle formed between the first and second vectors to exceed a predetermined threshold value. Information concerning the selected first point coordinates values are output to, for example, a host device.
