An example hologram device may include a target holographic view of an encoded holographic image representing an alignment target; and a plurality of non-target holographic views of the encoded holographic image, each non-target holographic view indicating a position relative to the target holographic view.

A non-transitory computer-readable medium having code stored thereon, the code includes instructions to receive an indication to communicatively couple a utility meter to an auxiliary device via a mobile electronic device, and capture a visual representation of a unique identifier of the utility meter via the mobile electronic device. The unique identifier includes an authentication mechanism configured to establish a first authentication and a second authentication of a user of the mobile electronic device. The code includes instructions to receive an acknowledgement to communicatively couple the mobile electronic device to the utility meter when the first authentication and the second authentication are satisfied.

A video calling service provides a mobile device user is provided the capability to transition from a voice call to a video call within a calling session in a voice over long term evolution (VoLTE). The example video calling service offers a seamless transition of a voice call to a video call in a simplified and efficient process. In an example, a graphical user interface is provided that allows a user to select controls to provide real-time stream of video of a live scene via a rear facing camera to another user during a video call. Other examples describe the merger of individual voice calls into a merged call with the individual calls grouped as a conference call. The examples provide simplified use of a mobile device to transition voice calls to a video call in a cellular carrier's mobile network.

In some implementations, a mobile computing device may participate in the calibration of an output signal of a media device. This calibration process includes storing device-specific calibration data which is related to properties of a light sensor of the mobile device. The mobile device then detects of properties of light emitted by the display device during a presentation to obtain sensor values related to light emitted by the display device during the presentation. The calibration process may also ensure that the mobile device is proximate to the display device prior to obtaining the sensor values. The collected sensor values are adjusted using device-specific calibration data stored to the mobile device to normalize the sensor values relative to a baseline. These normalized sensor values are sent to the media device for use in adjusting the output signal based on the normalized sensor values.

A method, device and terminal for adjusting focal length are provided. The method includes: after a camera of a terminal is detected to have been started, acquiring a first distance between the subject being captured by the camera and the camera; acquiring a first focal length corresponding to the first distance according to the first distance; and automatically adjusting the focal length of the camera to be the first focal length.

A method of operating a device to obtain biometric information from a subject includes the step of orienting a device relative to a sub jest such that a first portion of the device faces the subject, wherein a second FIG. 1A portion of the mobile device comprises a camera, the first and second portions being different sides of the device. The method may further includes the steps of operating an optical assembly that is movably coupled to the device, the optical assembly being configured to modify an optical pathway of at least the camera in a direction of the subject and acquiring imaging data of the subject using the camera. The method may further includes the steps of analyzing the acquired imaging data to generate biometric information corresponding to the subject and generating a report using the biometric information.
