A method of presenting a virtual class in a presentation having a start time, normal speed, and end time includes determining if the presentation is being started after the start time and if so, determining a delay tine; determining if the presentation is to be presented at the normal speed, and if so, presenting the presentation at the normal speed and finishing the presentation at the end time plus the delay time; if the presentation is not to be presented at the normal speed, presenting the presentation at an accelerated speed such that the presentation ends at the end time.

A dual-screen computing device includes two separate displays that are coupled to an interconnecting hinge. A hinge detector detects movement or position of the hinge, and the positions of the displays may be determined based on the hinge movement or position. The positions of the displays relative to each other may then be used to determine which mode of operation the dual-screen computing device is operating (e.g., tent mode, open, closed, etc.). Additionally, the dual-screen computing device may include various sensors that detect different environmental, orientation, location, and device-specific information. Applications are configured to operate differently based on the mode of operation and, optionally, the sensor data detected by the sensors.

A multi-person synchronous remote virtual reality teaching system and a method thereof, wherein the teacher downloads a virtual reality teaching course files through a teaching information device first, then shares the virtual reality teaching course files with each student to their learning information device. In the way, the student can pre-download the virtual reality teaching course files at the same time. Through the teaching information device, teachers may realize the place where each student's current sight is focused. In addition, the various virtual reality scenes in the above-mentioned devices not only let teachers actively switch or work on for teaching purposes, but also let students browse or study with a certain degree of freedom. Also, multiple hyperlinks are provided in the virtual reality scene for students to click for easy learning.

An e-learning system has a local classroom comprising a local student station and an instructor station, such that local students at the local student station and an instructor at the instructor station face each other directly along a first viewing line, a plurality of remote classrooms each having a student station, video cameras in each of the remote classrooms positioned and oriented to capture video images of subjects, video displays in the local classroom arranged along a line orthogonal to the first viewing line and all facing the local student station, in sets of at least two displays, arranged vertically one above another, each first set of at least two displays dedicated to one of the remote classrooms, a second plurality of video displays like the first, but facing the instructor, connection apparatus between classrooms, a server coordinating video feeds with displays.

A method of interaction using augmented reality may include aligning a local augmented reality (AR) view to a remote AR view of a remote user, receiving remote annotations from the remote user, sending local annotations registered to a local view to the remote user, and manipulating local view with remote and local annotations. The method may also include capturing a first video image using a camera, generating first augmented reality (AR) coordinates corresponding to the first video image, receiving second AR coordinates, 3D object information and second video frame from remote user, loading 3D content and instructions from a remote storage, and updating positions and existence of the received 3D object information and the loaded 3D content.

In a first aspect, the present disclosure relates to a computer-implemented method for generating a personalized lecture for a user. The method comprises obtaining at least one time series of electrodermal activity data of a user from a sensor and identifying a mental state of the user based on the at least one time series of electrodermal activity data. The method further comprises obtaining teaching content and generating a personalized lecture based on the mental state and the teaching content.

A student engagement device, system and method is provided that encourages students to maintain student engagement during a classroom activity or lecture. The device may be worn by the student and include a display that displays signals received from a remote controller. The signals are generated in the remote control based on subjective observation from the teacher related to student to engagement and may be irrespective of student behavior. The system may further include a computer device accessible by the student or parent for viewing student engagement levels during a class or over a longer length of time, such as a week, month, semester, or year.
