  • Publication number: 20190371344
    Abstract: 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.

  • Patent number: 10495797
    Abstract: The present application relates to a liquid crystal composition, a polarizing element and a use of the polarizing element. Since the polarizing element may be prepared by a simple coating process, the guest host type liquid crystal composition of the present application allows not only for reducing the manufacturing cost and lightweight thinning of the polarizing element, but also for manufacturing the polarizing element showing an excellent heat resistant stability without changes of absorption spectrum to transmission spectrum even in a severe condition such as high temperature environment. Such a polarizing element can be applied to various display devices such as liquid crystal display devices, EL display devices, field emission display devices, display devices using electronic papers, projection display devices or piezoelectric ceramic display devices.
