Technology for a wearable heart rate monitoring device is disclosed. The wearable heart rate monitoring device can include a heart rate sensor operable to collect sensor data, a modulator operable to generate a modulated signal that includes the sensor data, a housing configured to engage a body feature or surface in a manner that allows for heart rate detection, and a communication module configured to transmit the sensor data in the modulated signal to a mobile computing device via a wired connection that is power limited. The mobile computing device is typically configured to demodulate the modulated signal in order to extract the sensor data.

The present invention relates to: a message display method according to an event occurrence in a virtual reality (VR) device, wherein, when an event such as a telephone call, a text receipt such as an SMS, and a message receipt using a messenger program or an application occurs, during the displaying of a stereoscopic image through a head mounted display (HMD)-based VR device, in a communication terminal such as a smart phone combined with the VR device, a message according to an event occurrence is displayed by linking with a screen of the stereoscopic image being currently reproduced, thereby solving problems of severe discomfort sensation, which have occurred in conventional methods in which a message according to an event occurrence is displayed in a shape such as a black-based bar or box distinctly different from the stereoscopic image being currently reproduced, and thus is seen as an error message; and an apparatus therefor.

Embodiments of the present invention disclose a method and an apparatus for controlling a running status of a wearable electronic device. The method includes: determining a posture of a wearable electronic device, where the posture includes a stationary posture and a moving posture; and controlling a running status of the wearable electronic device according to the posture. According to the method and the apparatus for controlling a running status of a wearable electronic device in the embodiments of the present invention, the posture of the wearable electronic device is monitored by using, for example, a gyroscope signal from a mobile phone, whether a user is using the wearable electronic device is determined, and the running status of the wearable electronic device is determined without using a light sensor. This can reduce manufacturing costs of the wearable electronic device.

Method and device of encrypting communication between a server and a peripheral device are disclosed. The method includes: a server receiving a session request from a control device, the session request including a predetermined device ID of a peripheral device associated with the control device; generating a first session key for encrypting and decrypting future communication between the peripheral device and the server; identifying a pre-stored encryption key corresponding to the predetermined device ID from a database, wherein the pre-stored encryption key is also pre-stored in the peripheral device; encrypting the first session key using the pre-stored encryption key; sending the encrypted first session key to the peripheral device via the control device; and encrypting communication to the peripheral device in a respective communication session using the first session key.

A case for a portable device like a smartphone includes light sources such as LEDs, which, when illuminated, can be detected and tracked by a head-worn augmented or virtual reality device. The light sources may be located at the corners of the case and may emit infrared light. A relative pose between the smartphone and the head-worn device can be determined based on computer vision techniques performed on images captured by the head-worn device that includes light from the light sources. Relative movement between the smartphone and the head-worn device can be used to provide user input to the head-worn device, as can touch input on the portable device. In some instances, the case is powered inductively from the portable device.

An unlocking method and an unlocking apparatus are provided. According to an example, the unlocking method comprises: determining whether a mobile terminal to be unlocked exists; and sending a preset instruction to the mobile terminal when the mobile terminal to be unlocked exists, where the preset instruction is configured to control the mobile terminal to unlock a display screen.

In a virtual reality space, a virtual reference body controlled to follow a player's hand, a virtual body part controlled to follow the player's ear, and a virtual smartphone being a virtual object as a prop are arranged. After the proximity of the virtual reference body to the virtual smartphone, the virtual smartphone is deemed as being gripped and the virtual reference body and the virtual smartphone are integrally moved. Stereophonic sound control is performed such that the emitted sound from the virtual smartphone is a ringtone before the proximity of the virtual reference body or the virtual smartphone to the virtual body part, and after the proximity, the emitted sound is switched to communication sound so that the player listens to the stereophonic sound by a headphone.

The present invention provides a mobile terminal and a control method using an intuitive gesture as an input to perform a function. Specifically, the present invention provides a mobile terminal including a sensing unit for sensing movement of the mobile terminal, a wireless communication unit for transmitting/receiving a radio signal to/from an external terminal and a control unit for sensing a distance from the mobile terminal to the external terminal based on the strength of the received radio signal, and performing a specific function when the sensed movement corresponds to specific movement and the sensed distance is within a specific range.

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.
