The present invention relates to a method and apparatus for providing an emotion-adaptive user interface (UI) on the basis of an affective computing service, in which the provided service is configured with at least one of a service operation condition, a service end condition, and an emotion-adaptive UI service type on the basis of purpose information of the service, and the detailed pattern is changed and provided on the basis of the purpose information and the usefulness information of the service.

Method and apparatus for providing emotion-adaptive user interface

Disclosed is technology for providing a proper UI/UX through various devices or services when occurrence of registered concerned context is predicted or recognized in order to predict or recognize the circumstances that require attention or emotion control with regard to a change in his/her biological information With this, a user designates his/her own biological information range or emotional state with regard to circumstances which catch his/her attention, and registers concerned context by selectively designating attributes of circumstantial elements. Further, a user registers feedback desired to be given and an external device/service desired to interface with when the occurrence of the concerned context is predicted or recognized. According to the attributes of the circumstances designated in the registered concerned context, points in time for collecting and managing UX data are automatically determined, thereby processing and managing the UX data as useful information.

Apparatus and method for predicting/recognizing occurrence of personal concerned context

Disclosed is an electro-absorption optical modulator using a semiconductor device. The optical modulator makes use of a change in light absorption caused by displacement of an absorption curve depending on a bias voltage applied to the device. Here, a level of the light absorption depending on the bias voltage is expressed as a transfer function of output light to the applied bias, and the transfer function has a non-linear profile due to a characteristic of a material. Unlike signal modulation of a digital optical communication system, an analog optical transmission system can be subjected to deterioration in performance, because the non-linear characteristic of the transfer function for the optical modulator generates signal distortion when an electrical signal is converted into an optical signal. The typical optical modulator has an absorption layer constituted of quantum wells having the same width. However, the inventive optical modulator has the absorption layer formed by the combination of quantum wells having a width different form each other, thus having excellent linearity.
