    Abstract: The technology disclosed can provide capabilities such as calibrating an imaging device based on images taken by device cameras of reflections of the device itself. Implementations exploit device components that are easily recognizable in the images, such as one or more light-emitting devices (LEDs) or other light sources to eliminate the need for specialized calibration hardware and can be accomplished, instead, with hardware readily available to a user of the device—the device itself and a reflecting surface, such as a computer screen. The user may hold the device near the screen under varying orientations and capture a series of images of the reflection with the device's cameras. These images are analyzed to determine camera parameters based on the known positions of the light sources. If the positions of the light sources themselves are subject to errors requiring calibration, they may be solved for as unknowns in the analysis.

    Abstract: The technology disclosed can provide methods and systems for identifying users while capturing motion and/or determining the path of a portion of the user with one or more optical, acoustic or vibrational sensors. Implementations can enable use of security aware devices, e.g., automated teller machines (ATMs), cash registers and banking machines, other secure vending or service machines, security screening apparatus, secure terminals, airplanes, automobiles and so forth that comprise sensors and processors employing optical, audio or vibrational detection mechanisms suitable for providing gesture detection, personal identification, user recognition, authorization of control inputs, and other machine control and/or machine communications applications. A virtual experience can be provided to the user in some implementations by the addition of haptic, audio and/or other sensory information projectors.
