A head mounted display device and a power management method are provided. The head mounted display device includes a host device and a power input device. The power input device is detachably connected to a power device and an electronic device. The power input device generates a first input signal according to a supply voltage value of the power device, and generates a second input signal according to power supply information of the electronic device. The host device enters a power saving mode or performs a boot-up operation according to the first input signal and the second input signal.

The present invention relates to the control and operation of cellular telephones and other electronic devices, and particularly to improvements in the functionality of those devices for use in conjunction with a variety of sports and recreational activities.

Provide is a display terminal having a small display space, in which high operability is realized while convenience is maintained. A display terminal including a photographing device comprises: an image analysis unit configured to analyze an image captured by the photographing device, use region information that is information of a region on the image which corresponds to a real object existing in the external field, and refer to an icon DB so as to specify an icon related to the real object; and an app start unit configured to obtain an application associated with the specified icon from an app DB and start the application.

A three-dimensional (3D) communication device includes a 3D stereoscopic camera for capturing video and photos in 3D. The device also includes a 3D display, which enables the display of video and photos in 3D that have been captured by a local user's communication device or that have been received from a remote 3D communication device. The 3D communication device may be configured as a handheld standalone device or may alternatively be configured as a modular device, a case, or a dock that can be interfaced with a portable computing device, such as a smart phone, which lacks the capability to capture and view 3D video/photo content. As such, the 3D communication device enables 3D chat or communication between a local user and one or more remote users of the 3D communication device or any other computing device that is configured with suitable communication or chat software.

Provided are a wearable personal digital device and related methods. The wearable personal digital device may comprise a processor, a display, biometric sensors, activity tracking sensors, a memory unit, a communication circuit, a housing, an input unit, a projector, a timepiece unit, a haptic touch control actuator, and a band. The processor may be operable to receive data from an external device, provide a notification to a user based on the data, receive a user input, and perform a command selected based on the user input. The communication circuit may be communicatively coupled to the processor and operable to connect to a wireless network and communicate with the external device. The housing may be adapted to enclose the components of the wearable personal digital device. The band may be adapted to attach to the housing and secure the wearable personal digital device on a user body.

The present invention relates to apparatuses and methods to permit control and operation of an electronic device while participating in another activity, including a variety of sports and recreational activities. A control device, breakaway connector, and one or more speakers and microphones are provided and configured to enhance the ability of users to answer or end telephone calls or start, stop, or resume audio output to the speakers while a user is in motion or wearing gloves that would render the use of conventional call answer buttons difficult or impossible.

When an image capturing apparatus captures an image of an original screen and a finger reflected on an eye of a user, an operation determination unit determines the content of an operation performed with the finger based on image data of the captured image. An operation position identification unit generates data representing a position of the finger on the original screen based on the image data of the captured image. An input control unit recognizes a content of an input instruction corresponding to the operation performed with the finger, based on data on the content of the operation obtained by the operation determination unit, data on the position generated by the operation position identification unit, and data on the original screen stored in a storage unit, and controls the original screen to be displayed on a display apparatus according to the recognized content of the input instruction.

This watching system is provided with: a watching detection device that is provided with a cartilage conduction vibration source, a mastication sensor, and a bone conduction microphone and that is configured to be mounted on an ear such that the entry of the ear canal is opened; and a mobile phone or an in-home monitoring unit that receives watching detection signals from the mastication sensor and the bone conduction microphone by means of short-range communication and issues a notification to the outside. The watching detection device has an air conduction microphone and also functions as a hearing aid. When detection signals cannot be received from the mastication sensor or the bone conduction microphone for a predetermined time period, a notification is issued. The mobile phone and the in-home monitoring unit crosscheck watching detection information. The mobile phone also issues a notification of information indicating that there is no abnormality.

An apparatus with a selector input device to transmit media content items comprises a camera with a camera lens and an image sensor, a communication interface, and a selector input device. The apparatus can also comprise a processor and a memory having instructions stored thereon, when executed by the processor, causes the processor to perform operations comprising detecting activation of the selector input device. In response to detecting the activation, the processor can capture a media content item via the camera and transmit, via the communication interface, the media content item to a client device. Other embodiments are described herein.

A BLUETOOTH connection system includes a BLUETOOTH headset, and a first electronic device and a second electronic device that have been paired with the BLUETOOTH headset. The BLUETOOTH headset is configured to establish a first connection to the first electronic device, where the first connection includes an asynchronous connection-oriented link (ACL) connection. The BLUETOOTH headset is further configured to send a BLUETOOTH Low Energy (BLE) broadcast message. The second electronic device is configured to establish a second connection to the BLUETOOTH headset after receiving the BLE broadcast message.
