A modular wall organization system including one or plural board assemblies. Each of the board assemblies includes a frame and at least one planar panel held by the frame. Some of the frames include hollow frame sections and corner nodes, which connect the frame sections. The frame sections are configured to be used with hangers for mounting various types of accessories on the board assembly or for connecting plural board assembles together. Some of the accessories are trays, baskets, rolls of writing material, and panel insert assemblies. The panel insert assemblies include various panels, such as cork-boards, dry-erase boards, chalk-boards, fabric-boards, slat-boards, letter-to boards and other types of boards or panels. Some of the frames are in the form of solid frame sections.

A knowledge point mark generation system and a method thereof are provided. The system and the method thereof can obtain a label vocabulary by performing the analysis procedure on at least one second candidate vocabulary repeated by sound in a class, at least one first candidate vocabulary repeated by text during class, at least one second keyword highlighted by sound during class, and at least one first keyword highlighted by text during class according to their weights, and then set knowledge point marks on a timeline of a video file taken during class according to time periods when the label vocabulary appears. Thus, a learner can know the knowledge points of the class and their video clips in the video file without browsing the entire video file, so that it is convenient for the learner to learn or review the key points of the class.

A trifold presentation board assembly for securing and protecting a display includes a panel that comprises a first section and a pair of second sections. Each second section is hingedly coupled to a respective opposing edge of the first section and is positioned to be pivoted relative to the first section to selectively reposition the panel from an extended configuration to a folded configuration. A forward face of each of the second sections is positioned proximate to a front face of the first section so that the pair of second sections covers the front face of the first section. A plurality of couplers that is coupled to a rear surface of the panel is positioned to be selectively mutually coupled when the panel is in the folded configuration. The panel is configured to shield and protect a display article that is coupled to a front surface of the panel.
