  • Patent number: 10818195
    Abstract: A learning method to be implemented by an electronic device including a processor and a display unit and cooperating with an imaging frame includes: storing a set of image data related to a virtual 3D image of an object, and a total score associated with the object; displaying, by the display unit, image parts respectively on display areas that surround a central area according to the set of image data, in a manner that the virtual 3D image of the object is reconstructed in the imaging frame when the imaging frame is placed on the display unit and corresponds to the central area in position; determining, by the processor, whether a time duration for which the display unit displays the image parts is not smaller than a predetermined time duration; and when affirmative, adding, by the processor, a learning score to the total score.

  • Publication number: 20190066383
    Abstract: A method for performing an assessment of mental and behavioral condition of a subject includes displaying, by a virtual reality (VR) device, a VR scene; generating, by the VR device, a notification indicating an assignment for the subject in the VR scene; recording, by a recording device, a response of the subject to the assignment; calculating, by a processing device, at least one score based on the response; and comparing, by the processing device, the score with a pre-established normative scale to generate an assessment result for the mental and behavioral condition of the subject.

  • Patent number: 9269257
    Abstract: The method and system for reminding readers of fatigue in reading while using electronic devices are revealed. First use a reading speed calculation module to detect user's reading speed within a period of time when the user is using an electronic with a display to read. The reading speed is related to pages being turned or the amount of words being read. Then a fatigue-in-reading reminder module is activated by the reading speed calculation module when the user's reading speed falls within a specific range so as to remind the user by pop-up windows, sounds, flash light or vibration at the proper time and provide the user certain corresponding measures he/she should take. Thereby there is no need to use additional equipment for preventing users from becoming more fatigue and healthy vision is accomplished at lower cost with higher efficiency.

  • Publication number: 20140335502
    Abstract: A real-time video annotation learning system and a method for the same are revealed. The real-time video annotation learning system includes a video management module, an annotation management module and a data storage module. A language learner can select videos stored in the data storage module by the video management module and add comments to a location of an image in the video at a specific time while the comments are in the form of text or graphs built in a commentary management module. Thus the comments are shown on the image in the form of text or graphs at a specific time. Users can grasp key points of learning content the video provided exactly. Together with system functions of real-time word look-up and word note, user's learning effect is significantly improved and the video has an advantage in language learning.
