Aspects of this disclosure relate to a biometric sensing device that combines sensing with an actuator for two way communication between a finger on a surface and the device. The sensor can also function as an actuator. A finger can be authenticated based on an image of the finger generated by the sensor and also based on a response to energy delivered to the finger by the actuator. Two way communication can provide more robust authentication than fingerprint sensing alone.

A sensor for sensing biometric information includes a light emitting unit that emits a first light ray, a light receiving unit that receives a second light ray, where the second light ray includes a portion of the first light ray reflected by a body of a user, and an optical layer placed over the light emitting unit and the light receiving unit. The optical layer has a first surface facing the light emitting unit and the light receiving unit and a second surface opposite the first surface. The optical layer further includes an asymmetrical protrusion structure formed on the first surface or the second surface and including a plurality of asymmetrical protrusion units. The optical layer may further include a symmetrical protrusion structure formed on the first surface or the second surface opposite the asymmetrical protrusion structure and including a plurality of symmetrical protrusion units.

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.

A mobile, wireless biometric identification system includes a biometric capture device which enables a smartphone, using a commercially established wireless communication networks, to capture a digital image of a human biometric (iris, fingerprint, etc.) for transmission to a central server. The biometric capture device captures a high quality image for encoding and comparison, while the overall system leverages the existing cellular communication network. The device can be used as an interface to medical databases and devices used to diagnose and treat patients.

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.

There is provided systems and methods for performing actions based on light signatures. An exemplary system includes a light source, a light detector, a non-transitory memory storing a plurality of light signatures and a hardware processor. The hardware processor executes an executable code to illuminate, using the light source, a target object with a first light, collect, using the light detector, a second light being a reflection of the first light by the target object, match the second light with one of the plurality of light signatures, and perform an action in response to matching the second light with the one of the plurality of light signatures.

A contact display method and a user terminal for performing the same are disclosed. The disclosed content display method identifies content included in a surrounding area of a user terminal, determines a position of the user terminal relative to the content, and outputs a virtual object augmentatively to a blind image corresponding to a blind region covered by the user terminal, on the basis of the content and the position of the user terminal.

An ink file output method is provided, which includes: generating M (M is an integer of 1 or more) pieces of stroke data SD on the basis of event data generated as M input devices move, respectively; generating N (N is an integer of 1 or more and M or less) kinds of logical names LN (metadata) identifying the M number of input devices; generating a metadata block associating the M pieces of stroke data SD with the N kinds of logical names LN; and writing the M pieces of stroke data SD and the metadata block to an ink file.
