Abstract:
A head mounted device (HMD) includes an imaging unit configured to capture at least one image of a partial region of an iris, an electrocardiogram (ECG) sensor configured to receive an ECG signal, and a control unit configured to acquire at least one image of the partial region of the iris and ECG signals, and authenticate a user by using the acquired image(s) of the partial region of the iris and the ECG signals.
Abstract:
A contact lens including an energy harvesting unit is provided. The contact lens includes a sensor that detects biometric information of a user, and a power that transforms a dynamic energy generated by a movement of an eye part of the user into electrical energy and provides the sensor with the electrical energy.
Abstract:
A method of wirelessly connecting a first device to a target device is provided. The method includes searching for at least one device located in an orientation region of the first device, when a first input signal is received, determining the target device based on a direction that the first device is oriented, performing a wireless connection with the target device, and determining whether to maintain the wireless connection with the target device, when a second input signal is received.
Abstract:
A method performed by a wearable device to provide feedback includes detecting a user motion; determining, based on the detected user motion, a body part to which a feedback signal is to be transmitted; generating the feedback signal; and outputting the feedback signal, wherein the feedback signal is an electrical signal to stimulate muscles of the body part.
