A wearable device can facilitate automatic adjustment of a volume control and/or other settings of a host device based on properties of the ambient environment. For example, when a host device generates an audible alert, a wearable device can sample the ambient sound to detect a distinct contribution corresponding to the audible alert; if the contribution is outside acceptable levels, the wearable device can notify the host device to adjust the alert volume and/or other alert characteristics. Adjustments to host-device settings can also be made based on comparing audio signals collected by the host device and the wearable device.

A system and method of determining a tilt angle of a portable computing device using a sensor indicating gravitational pull on the device; determining the tilt angle of a camera of the device; identifying a tilt angle range from a plurality of predetermined tilt angle ranges; determining a first focal length setting using a first array that associates the tilt angle range with the first focal length setting; determining an adjustment increment using a second array that associates the adjustment increment with the tilt angle range; and determining a second focal length setting of the camera using the adjustment increment according to an autofocus scan range algorithm. A portable computing device including a processor; a camera; and a memory device including instructions operable to be executed by the processor to perform a set of actions, enabling the portable computing device to perform the method.

Provided are a gesture control method, a gesture control device and a gesture control system. The gesture control method includes: establishing, by a mobile terminal, a wireless communication connection with a display device; displaying, by the mobile terminal, a gesture input interface corresponding to a current application of the display device; detecting, by the mobile terminal, a user gesture; converting, by the mobile terminal, the user gesture into an operation instruction corresponding to the user gesture; and transmitting, by the mobile terminal, the operation instruction to the display device.

A dialing method for a user terminal is provided. The method includes: detecting, by a user terminal, at least one entering operation performed on a moment indication numeral on a clock dial, where the clock dial is displayed on a standby screen of the user terminal; determining, by the user terminal, a dialing numeral corresponding to the entering operation; generating, by the user terminal, a dialing number according to the dialing numeral; and performing, by the user terminal, a call by using the dialing number as a called number, a user may perform a dialing operation by using the standby screen of the user terminal, and can perform the dialing operation without a need to enter a home screen by using the standby screen and then enter a dialing screen by using the home screen.

A smart phone/apparatus/machine configured to enable a user to take a picture and associate audio and text data to the picture immediately thereafter, and then send such associated data to others.

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 protective case, sized and shaped to encase a mobile device such as a smartphone or a tablet computer, includes a top section and a bottom section. The top section and bottom section are capable of being engaged to one another in a closed relationship, in which the mobile device may be hermetically sealed or isolated from the outside environment. The top section and bottom section may be readily engaged to or disengaged from one another. Embodiments of the protective case may include membrane that includes a first membrane portion and a second membrane portion, the membrane portions having different qualities.

A method performed by a mobile device includes causing display of graphical tiles on a display of the mobile device and detecting a gesture while displaying the graphical tiles. The gesture includes an indication to move a particular graphical tile among the graphical tiles. In response to the gesture, the mobile device can automatically move another graphical tile to accommodate the new location of the particular graphical tile and cause display of the graphical tiles arranged in a new order that includes the particular graphical tile in the new location.

An electronic device including a housing including a front panel and a rear panel, the rear panel arranged on a side of the housing opposite the front panel, a processor configured to execute instructions and the processor being arranged within the housing, a display device configured to generate an interface based in part in response to the processor, where the display device is arranged in the front panel, a touchscreen associated with the display device and configured to sense a user input, where the user input is provided to the processor and where the touchscreen include part of the front panel, and a rear input arranged on the rear panel of the housing and configured to provide a dedicated input to the processor, the processor providing advanced user controls on the interface in response to operation of the rear input.

Disclosed are a mobile terminal and a control method therefor. The mobile terminal, according to one embodiment of the present invention, comprises: a camera provided to a main body; a display unit for displaying a preview image for the photographing of the camera; and a control unit for detecting the entering into of a subject information search mode while the preview image is being displayed, and in the information search mode, detecting the selection of one search option among a plurality of search options for a subject. In addition, on the basis of a touch input applied to the preview image, the control unit photographs the subject, including an object to which the selected search option is to be applied, and displays, on the display unit, an image of the photographed subject along with a screen where the selected search option is applied.
