A method for controllable toggling viewing of written materials with adjuvant or explanatory notation material as a teaching or memorization tool. The method comprises the steps of imprinting adjuvant or explanatory notation materials adjacent to or in close conjunction with a visible text or notation, as a non visible or an invisible imprint. The non visible invisible adjuvant or explanatory notation material is made to become temporarily visible or viewable with a heat source or a viewing device for a controlled desired period of time by using the visible adjuvant or explanatory notation to perform a reading or writing function. Removing the viewing device or reducing heat renders the adjuvant or explanatory notation non visible or invisible.

A method can include displaying, by a user interface (UI) of a device, a first keyboard including first character keys, the first character keys each including a respective Roman character and corresponding Hiragana characters displayed thereon, in response to receiving one or more signals indicating a user selected a first character key of the first character keys, displaying a second keyboard including second character keys in place of the first keyboard, the second character keys including a respective Roman character and only one corresponding Hiragana character of the corresponding Hiragana characters displayed thereon, and in response to receiving one or more signals indicating a user selected a second character key of the second character keys, displaying the Hiragana character displayed on the second character at location of an insertion point and displaying, by the UI, the first keyboard.

A children's educational building block set that allows children to incorporate material selection, landscaping, and environment considerations into the design of an architectural feature. With the blocks of the present invention, children learn to see buildings as part of the environment and the land, and not separate from them. The set includes a plurality of building blocks formed as a geometric solid carrying indicia of a design element on a face of each block. A set of architectural material blocks permits the forming of an architectural structure, including a roofing, a siding, and a fenestration element. Foreground and landscape blocks carry indicia for a landscape or foreground to frame a base of the structure. Environmental blocks may surround a periphery of the structure.

A coding toy includes a control object (a figure body) having a control unit, an input unit and an output unit, and a part (an icon block) having a code identifier (an icon) that corresponds to a control detail of the control object. The control unit of the control object obtains code identifier information and positional information from the code identifier indicated by the part disposed in a predetermined position and the position of the part and controls the output unit to a control detail and in a control sequence that are determined by the code identifier information and the positional information.
