Ludic-educational modular system including plurality of electronic modules each including: common portion to all the modules including, equivalent storage medium including a pre-programmed computer program, an equivalent computer connected to the storage medium to process input data and return output data based on the program, equivalent first interface connecting to each other the modules, equivalent second interface connecting the module to an external electronic device or another module and transmitting input data and output data between the module to a device or another module, a singular portion including functional apparatus connected to the computer performing a predetermined function by generating the output data based on at least one parameter settable in the computer program, and the computer allowing the manipulation, by the functional apparatus and/or device, of at least one parameter to an external user to allow only configuration of the function without modifying the program programming.

Disclosed are mortise and tenon joint structures for Chinese characters formed by building members having the same or different configurations, and a method for inputting Chinese characters by using the building members. The Chinese characters are de-structured such that each Chinese character consists one or more radicals which are formed by the mortise and tenon joint structures or variants thereof. The variants of the mortise and tenon joint structures are formed by shift, rotation or combination of shift and rotation of the building members of the mortise and tenon joint structures. This establishes an inputting method between the Latin letters and Chinese characters.

An interconnecting alphabet toy corresponding to at least one letter from a book, including a plurality of main bodies, at least one protruding portion disposed on at least a portion of at least one side of at least one first of the plurality of main bodies, and at least one protrusion-receiving groove disposed on at least a portion of at least another side of at least one second of the plurality of main bodies to receive the at least one protruding portion therein, such that the at least one first of the plurality of main bodies and the at least one second of the plurality of main bodies interconnect to form the at least one letter.

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.

A pegboard of the present disclosure includes: a main device including multiple unit modules; a board plate including multiple receiving portions; and multiple pegs to be inserted into the multiple receiving portions, and the multiple unit modules include multiple sensor modules configured to sense whether the multiple pegs are inserted into the multiple receiving portions and multiple light source modules configured to output light to the multiple receiving portions.

A pegboard training method, includes: receiving a game execution request from a user by a pegboard training device; providing the user with a game for which the execution request has been received by the pegboard training device; recognizing the user's insertion of a peg for the game by the pegboard training device; and guiding the user to an evaluation of a game result based on the insertion of the peg recognized by the pegboard training device after the game is over. The pegboard training device is configured to provide the user with training by using insertion pegs onto a board including a plurality of holes, and the game is executed by at least one of inserting a peg into at least one hole presented by the pegboard training device on the pegboard, inserting a peg by the user into a hole, which has not been presented by the pegboard training device, on the pegboard at the user's discretion, and removing a peg inserted in a hole by the user after the pegboard training device guides the user to remove the peg.
