A method includes providing a mission regarding image capturing to a user terminal having an image capture function, evaluating an image transmitted from the user terminal in response to the mission, and additionally providing a new mission regarding image capturing to the user terminal in a case where a level of achievement of the mission is determined to satisfy a criterion based on the evaluation.

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.

A system and method for teaching children in the field of music, and more particularly to teach children to play the piano and read musical notes using physical objects with images of characters assigned to fingers and animals assigned to musical notes, with assigned colors and shapes, and all incorporated within themed environments presented in continuing stories.

An arithmetic game is played by selecting a target value that is an integer between 1 and 9. A field of initial integers is selected and subsequent fields of integers are generated by strategically selecting and combining integers from the field of initial integers or from another subsequent field of integers. At least one combined integer or at least one operated integer is added to, subtracted from, multiplied by, or divided by at least one other combined integer or at least one other operated integer to produce at least one sum, difference, product, or quotient that is a calculated integer. Subsequent fields of integers are created until a target field is created with no carried integers and the remaining calculated or combined integers are added, subtracted, multiplied, or divided to produce a sum, difference, product, or quotient that is the target value.

A programmable robot includes a body, a pair of drive wheels rotatably coupled to the body, a pair of electric motors in the body for driving the drive wheels, a receiver unit configured to receive at least one wireless command from a programming device, a sensor configured to sense a surrounding environment of the programmable robot, and a controller operably connected to the receiver unit and the sensor, the controller configured to control operation of the electric motors in response to the at least one wireless command received from the receiver unit and a data signal received from the sensor.

The present invention discloses a writing board, solving the problems of large occupied space due to large area, high transportation cost, easy damage and high scrappage rate in the existing writing board.
