Headpiece includes a frame having support structure for supporting the frame on a person's head and a viewing portion in front of the person's face. A light valve assembly in the viewing portion has a first state in which the person can view an object in front of the headpiece and a second state in which viewing of the object is prevented. A biometric identification system on the frame attempts to obtain biometric data about the person. A processor controls whether the light valve assembly is in the first or second state by analyzing biometric data relative to previously obtained biometric data associated with the person and when the analysis indicates that the biometric data does not match, the processor controls the light valve assembly to change from the first to the second state and prevent viewing of the object.

The present invention relates to a method, system, and non-transitory computer-readable recording medium for providing learning information. According to the invention, it is possible to consider, in providing supplementary learning information to a learner, both of a supplementary learning pattern common to all learners and a supplementary learning pattern of a specific learner whose characteristics are similar to those of the learner, so that learning units necessary for supplementary learning of the learner may be found accurately and efficiently.

Systems and methods are provided that facilitate publishing, distributing, and reading of electronic content. In some embodiments, the systems and methods may include a document conversion module for converting documents uploaded by publishers into an e-reader friendly format (an e-document). The systems and methods may also include a virtual library for making the e-documents available to end users and an active reader module to allow an end user to download and read the e-documents on an end user device. In some embodiments, the systems and methods may include a user management module for digital rights management and control of end user access to the e-documents. In some embodiments, the active reader may include functionality that allows an end user to annotate the e-document and share comments among users.

Systems and methods for avoiding network congestion on a web-based survey system are provided using dynamic profiling of users and transmitting the most valuable survey. The system can receive information associated with a user and a number of surveys requested. The system can prompt the user to respond to the first set of routable questions. The system queries a router for a set of surveys with open sub quotas based on the information associated with the user and the answers to the first set of routable questions. The set of surveys are inserted into a list of surveys. Each survey in the list of surveys is assigned a score based on the priority of the survey, the difficulty of the survey and the urgency of the survey and sorted. The system can transmit at least one survey from the list of surveys.

Headpiece for test-taking includes a frame having support structure for supporting the frame on a person's head and a viewing portion configured to be in front of the person's face when the frame is supported on the person's head, and at least one light valve assembly arranged in the viewing portion. Each light valve assembly has a first state in which the person is able to see therethrough and an alternative second state in which viewing therethrough is prevented. A controller controls whether the light valve assembly is in the first state or the second state to thereby control viewing therethrough. The light valve assembly may be situated rearward of part of the viewing portion. Only the headpiece wearer is thus able to view test questions on a display through the light valve assembly.
