  • Patent number: 6931153
    Abstract: A handwritten character recognition apparatus has a character string input area of a size that allows a user to hand write a plurality of characters thereon using a stylus. A coordinate detection unit extracts a coordinate string for each stroke that forms the handwritten character string. An input completion judgement unit judges an immediately preceding handwritten character string to be complete if a time difference between a last coordinate of an immediately preceding stroke and a first coordinate of a stroke being input is at least a predetermined time, when the first coordinate of the stroke is detected in a first area of the character string input area. A character segmentation unit segments a stroke string for each character from all the strokes of the previously input hand written character string from which a character recognition unit recognizes each character and outputs a character string which is the recognition result.

  • Patent number: 6885759
    Abstract: A calibration system for a vision-based automatic writing implement is disclosed. The automatically controlled writing implement is appended to an articulated robot arm. The writing implement draws or writes on a substrate and recognizes what a user draws or writes on the same substrate. The user may move the substrate while drawing, thereby confusing the drawing and recognition processes. Accordingly, a controller draws a target on the substrate initially. Before each drawing or recognition step, the controller uses a digital video camera to find and recognize the target and determine whether the substrate has moved. The target is asymmetrical, such that the controller can determine the orientation as well as the position of the substrate. The controller can then orient its drawing and recognition algorithms to the new location and orientation of the substrate.

  • Patent number: 6657618
    Abstract: A device is provided for capturing complete analog motion, rather than digital events. A beam of columnated light, generated from a laser emitting diode, it directed at a clear, rotatable ball bearing having a series of reflecting indicia within the surface of the ball bearing. The reflection of columnated light off of these indicia makes the analog motion of the ball bearing a capturable, optical event. A sensor reads through the clear ball bearing and converts this motion into memory. The raw data then goes into the temporary RAM, which holds all excess data as other date is streamed into the microprocessors. Those processors change the raw data into digital code, which can then be understood and translated by most modern personal computers. The digital code can then be stored in the unit's non-volatile RAM, where it remains until it is uploaded into a PC resident software program.

  • Patent number: 6445820
    Abstract: A method for electronic analysis of handwriting samples. A digital bit-map of handwriting samples created, using a digital camera or electronic scanner. The bit-map is then marked at selected points using a cursor to obtain measurements, such as the slant angles of strokes and height measurements of major areas in the writing. The measurements are tabulated and may be used to authenticate the handwriting sample. Also, the tabulated results may be compared with predetermined standard profiles for determining certain characteristics relating to the person who produced the handwriting sample. The invention also provides a method for determining the pressure and angle of the writing instrument, by creating a three-dimensional representation of portions of the writing sample for measurement and analysis.

  • Patent number: 6330359
    Abstract: This invention provides an input apparatus which can correctly recognize and accept hand-written characters as soon as they are input without using such an input device as an optical character reader or a keyboard. when characters, etc., are written using a writing instrument having a pen grip (22) fitted thereto, the pressure of fingers applied to the writing instrument is measured by strain gauges (28a, . . . , 28c). The strain gauges (28a, . . . , 28c) output the pressure change of the fingers as waveforms representing electrical changes to a CPU. The CPU (40) separates the waveform into unit waveforms each corresponding to one character, and analyzes wave characteristics for each unit waveform. The waveform characteristics of the written character are then compared and collated with the waveform characteristics of each character of a writer which are in advance learned and stored. Accordingly, the hand-written characters can be correctly recognized immediately after written. Since mercury switches (29a, .
