摘要： The techniques in the present invention allow both text and handwritten queries, and the queries can be single-word or multiword. Generally, each handwritten word in a handwritten document is converted to a document stack of words, where each document stack contains a list of text words and a word score of some type for each text word in the list. The query is also converted to one or more stacks of words. A measure is determined from each query and document stack. Documents that meet search criteria in the query are then selected based on the query and the values of the measures. The present invention also performs multiple recognitions, with multiple recognizers, on a handwritten document to create multiple recognized transcriptions of the document. The multiple transcriptions are used for document retrieval. In another embodiment, a single transcription is created from the multiple transcriptions, and the single transcription is used for document retrieval.

摘要： A digital pen that has a writing tip includes an ultrasonic (US) transducer on a pen body that generates frames of US pulses toward a receiver base in response to an infrared (IR) synchronizing signal from the base. The first pulse of a frame is adjusted by a modulo of the US period &tgr; when the time of arrival (TOA) of the first pulse varies from an expected TOA by more than one-half &tgr;. The TOAs of successive ith pulses in the frame, which are one wavelength apart from each other, are adjusted forward in time by subtracting from each pulse TOA (i−1)&tgr;, and then several of the adjusted pulse TOAs in a single frame are averaged together to determine a frame TOA. The frame TOAs from plural receivers on the base are then triangulated to determine a pen position for that frame, with the pen positions being input to a handwriting recognition module.

摘要： Improved techniques are disclosed for adapting signature verification systems to natural signature variations. For example, a technique for adapting a signature verification system to variations in a signature of a user includes the following steps/operations. One or more signature samples are obtained from the user. The one or more obtained signature samples are submitted by the user as part of a regular authentication procedure associated with the signature verification system. A reference set of signature samples for the user is updated through selection of one or more signature samples from the obtained signature samples, such that the updated reference set is usable by the signature verification system for verifying subsequent signature samples attributed to the user. The selection of the one or more signature samples used to update the reference set is conditioned on a false rejection rate of the user when at least one obtained signature sample of the user is authenticated and on an identification check when no obtained signature sample is authenticated.

摘要： A system and method for calibration-free tracking of a user's eye gaze vector and point of regard even if substantial head movement or rotation occurs. The preferred embodiment includes two synchronized interlaced cameras, each viewing the user's eye and having on-axis lighting that is alternately modulated. An image difference between lighted and unlighted images of the eye is used to identify a user's pupil. A plane containing the gaze vector is defined by rotating a base plane through the angle in a camera image plane between a pupil center, a first glint, and a second glint. The intersection of two such planes (one from each camera), defines the gaze vector. The gaze position is the intersection of the gaze vector with the object being viewed by the user. Alternate embodiments are also described.

摘要： The present invention provides for touch input functionality in a liquid crystal display having a plurality of cells each comprising a first substrate having a common electrode integrated thereon, a second substrate having a pixel electrode integrated thereon, and liquid crystal material disposed between the common electrode and pixel electrode. A first conductive layer (signal layer) and second conductive layer (guard plane layer) are integrated onto the first substrate and disposed between the first substrate and the common electrode. Contact position of a touch input device with the first substrate is determined by applying a first signal to the signal layer. A second signal is applied to the guard plane layer to thereby lower capacitive coupling between the signal layer and the common electrode. The second signal may be generated by scaling amplitude and/or phase shifting the first signal. Response to the first signal is measured to determine contact position of the touch input device. Preferably, the portion of the signal layer disposed opposite the pixel electrode is a patterned layer of black matrix material, and the guard plane layer may be a transparent ITO layer. Alternatively, portions of the signal layer and guard plane layer disposed opposite the pixel electrode may be a patterned layer of black matrix material. A resistor network may be coupled to the signal layer to linearize resistance of the signal layer in a horizontal and vertical direction. By lowering the capacitive coupling between the signal layer and the common electrode, the guard plane layer and signal applied thereto enables the determination of contact position of a portion of the human body (such as a finger or a toe) based upon the measured response to the source signal. The present invention may be in display systems wherein a matrix of display elements are viewed from above a first side of a substrate and the display elements are disposed on the second side (i.e., the opposite side) of the substrate.
