摘要： An apparatus (100) for performing spherical geometry is disclosed. The apparatus (100) includes a frame (102) having a base (104) and a sphere set (106) placed on the base (104). The sphere set (106) includes an outer sphere (108) having a transparent surface and an inner sphere (110) having a surface representing a graph template, which includes azimuth and polar angle scales. The inner sphere (110) is held in a default static orientation with reference to the base (104) and is concentric with reference to the outer sphere (108) by a levitating arrangement. The outer sphere (108) is supported on the base (104) and is rotatable in any direction independent of the inner sphere (108) for determining spherical geometry measurements based on the graph template.

摘要： A rotational device is provided that enables a user to tangibly experience movement of a three-dimensional object in a four dimensional space. The rotational device includes an inner cubic frame assembly rotatably supported within an outer frame. The outer frame is formed from a series of wires connected at hubs to enable the user to view the movement of the inner cubic frame. A rotation mechanism may be provided to allow a user to rotate the inner cubic frame within the outer frame. A fixed internal cubic frame is mounted within the outer frame to support the inner cubic frame assembly. The inner cubic frame assembly includes an inner cubic frame and a sphere supported within the inner cubic frame. Reference points or nodes are provided on the inner cubic frame to provided visually traceable reference points as the inner cubic frame rotates within the outer frame and fixed internal cubic frame.

摘要： Provided are a method, an apparatus, an electronic device, and a storage medium for displaying an expansion of a 3D shape, including: determining a 3D shape to be expanded, and acquiring a target expanded state of the 3D shape; searching a preset multi-level information relationship table for an articulation relationship set corresponding to the target expanded state; determining, according to the articulation relationship set and a preset expansion rule library, a target expansion rule for each target plane surface on the 3D shape; and controlling to expand each target plane surface at a predetermined a rate based on the each target expansion rule, and displaying the expansion process in real time. The method dynamically displays an expansion process of a 3D shape to a student, such that the student can understands more about the process of transformation from a 3D shape to a selected expanded state, thereby improving user experience of a teaching demonstration function on an electronic device.

摘要： Shape-matrix geometric instruments having numerous applications including, but not limited to, anti-counterfeiting, graphical passwording, games, and geometry education. A shape-matrix geometric instrument is a manufacture and/or a method whose design is based on a shape-matrix that, in turn comprises a set of building blocks that are N-dimensional polytopes. Corner shapes are positioned in or near the interior corner spaces of at least ones of the shape-matrix building blocks. At least ones of the corner shapes differ from others in at least one property or aspect including, for example, geometric shape, orientation within the building block, and one or more surface “finishes,” such as color, shading, cross-hatching or real or apparent texture.

摘要： A trigonometric function display clock includes a clock face that has a center aligned with a central axis, axial markings aligned with an x-axis and a y-axis, and a secondary circle having a diameter equal to a radius of the axial markings. A first point on the secondary circle is aligned at the center of the central axis, and the secondary circle is configured to be rotatable about the first point. The secondary circle is configured to overlap and align with at least a portion of the axial markings as the secondary circle rotates about the first point.

摘要： An educational apparatus is disclosed. The educational apparatus has one or more first sheet members including a first side and a second side, the first side and the second side each having first markings indicating the same first surface area, and one or more first attachment portions disposed along some or substantially all of a perimeter of the one or more first sheet members. The educational apparatus also has one or more second sheet members including a first side and a second side, the first side and the second side each having second markings indicating the same second surface area, and one or more second attachment portions disposed along some or substantially all of a perimeter of the one or more second sheet members.

摘要： A method and system for using a natural language generator for automatic assessment item generation is disclosed. The natural language generator includes a document structure generator that produces an abstract document specification defining a structure for an assessment item based on user input. The abstract document specification is input into a logical schema generator, which produces a logical schema specification that creates a more detailed specification for an assessment item. Finally, a sentence generator receives the logical schema specification and creates natural language for the assessment item based on the variables defined in the logical schema specification.
