A method implemented by a transmission device to communicate with multiple reception devices that respectively share a drawing area with the transmission device is provided. The transmission device transmits to the multiple reception devices vector-data ink data representative of traces of input operation detected by an input sensor of the transmission device. The method includes: (a) an ink data generation step of generating fragmented data of a stroke object, wherein the stroke object contains multiple point objects to represent a trace formed by a pointer, the fragmented data being generated per defined unit T, and generating a drawing style object; (b) a message formation step of generating messages including the drawing style object and the fragmented data; and (c) a transmission step of transmitting the messages.

Devices and methods are disclosed for generating input. In one implementation, a stylus is provided for generating writing input. The stylus includes an elongated body having a distal end, and a light source configured to project coherent light on an opposing surface adjacent the distal end. The stylus further includes at least one sensor configured to measure first reflections of the coherent light from the opposing surface while the distal end moves in contact with the opposing surface, and to measure second reflections of the coherent light from the opposing surface while the distal end moves above the opposing surface and out of contact with the opposing surface. The stylus also includes at least one processor configured to receive input from the at least one sensor and to enable determining three dimensional positions of the distal end based on the first reflections and the second reflections.

An object is recognized from image data as a target object and linked to a user based on an interaction by the user, information about the target object is obtained and a purchase of the target object is initiated.

An absorbent article has one or more fluid filter layers to inhibit electrode traces from being exposed to low volumes of fluid to reduce the number of false positives that are indicated by an RFID tag of the incontinence detection pad. An antenna inlay has a sacrificial trace portion to permit testing for proper operation of an RFID chip electrically coupled to the antenna inlay. After testing, the sacrificial trace portion is severed. A fluid barrier layer blocks fluid from reaching portions of electrode traces that are located on a backsheet outside a periphery of an absorbent core of an incontinence detection pad. The power at which an antenna transmits to wirelessly energize a passive RFID tag of an incontinence detection pad is controlled to reduce the number of false positives indicated by the RFID tag.

An electronic handwriting device (e.g., a tablet device or smart phone) detects a first touch and a second touch (e.g., from a pen device) on or near a writing surface of the electronic handwriting device. The electronic handwriting device determines whether the first touch is a dropped touch. Upon determining that the first touch is a dropped touch, the electronic handwriting device applies data filtering to data that is potentially associated with the second touch. After the data filtering step, the electronic handwriting device determines whether to generate a stitching segment between a first line segment associated with the dropped touch and a second line segment associated with the second touch. The determination of whether to generate the stitching segment also may be based on other factors, such as the proximity of the second touch to the dropped touch.

A disposable lens applied to electronic operation device for recognition includes a substrate, a lens and a fix adhesive. It is only necessary for the user to fix the disposable lens to the electronic operation device provided with an image-capturing unit and enable the image-capturing unit to align with a recognized unit to be recognized through the lens, such that the image of the recognized unit is expanded through the lens through optical properties. Thus, the image signal captured by the image-capturing unit is clearer, and then processed by the electronic operation device. Not only compactness with portability enabling the user to recognize the recognized unit immediately, but also the effect of low-priced material are provided due to simple structure of the disposable lens of the present invention. Thereby, relative advantages in volume, convenience and cost are all obtained.

A computer-implemented method executed on an electronic device, the electronic device having a display screen, the method comprising: displaying an image on the display screen; receiving a user selection of a first portion of the image; responsive to the user selection of the first portion of the image, the first portion of the image containing a selected text portion, performing text recognition of the selected text portion and of an unselected text portion, the unselected text portion located in a second portion of the image being distinct from the first portion of the image, to render a recognized text element.

An electronic device, according to various embodiments of the present disclosure, may include: an image sensor that obtains the first image; an image processing unit that processes the obtained first image to thereby create the second image; an image quality inspecting unit that performs image quality inspection on the basis of the created second image; and an iris recognition unit that, if the image quality of the second image satisfies a predetermined condition, performs iris recognition on the basis of the obtained first image.

Technologies pertaining to composing, displaying, and/or transmitting handwritten content through utilization of a touch-sensitive display screen of a mobile computing device are described herein. A user of the mobile computing device can set forth strokes on the touch-sensitive display screen, one on top of another, wherein such strokes correspond to different handwritten characters. Stroke segmentation can be undertaken to determine which strokes correspond to which characters in a handwritten sequence of characters.

A system and method for authenticating a user of a device. A multi-band biometric iris scan camera system is capable of obtaining an iris image using near-infrared (NIR) light and/or visible wavelength (VW) light. The camera system can initially image a user to detect the iris color of the user and, based on the iris color, determine whether to use the NIR iris scan or the VW iris scan. Additionally, NIR and VW systems can be operated as integrated camera systems. The iris scan camera system can take a series of images and compare against a database of anonymous iris images captured at different illumination conditions, for selecting a preferred illumination condition for capturing the iris and performing authentication. The iris scan camera system can optionally track eye movement to determine when to trigger an iris scan, identify obstructions to the iris such as eyelids and eyelashes to implement corrective measures in the iris image processing, and identify facial features to determine whether the left and/or right eye is being imaged.
