A method for and system for guiding a user in creating a craft. At least a portion of a selected crafting challenge is displayed on a portion of a display surface which is visible through a crafting surface. A composite guide element is shown on the display surface visible next to the display surface part which is visible through the specific crafting surface and a further composite guide element is also provided at a receptacle corresponding to the displayed composite guide element. It is ensured that the composite guide element and the further composite guide element provide at least two mutually independent instruction components.

There is provided an information processing apparatus and an information processing method capable of intuitively and easily indicating a state of feeling of the autonomous moving body to the user. The information processing apparatus includes a control unit that, according to a change in a position of the autonomous moving body sensed by a sensing unit that senses the position of the autonomous moving body and a feeling parameter indicating the feeling of the autonomous moving body, causes a display screen to display a figure corresponding to the autonomous moving body while changing a state of the figure. The present disclosure can be applied to, for example, an apparatus and the like that controls an autonomous moving body.

Sound-generating toys are disclosed herein. In some embodiments, a sound-generating toy includes a squeezable body defining an internal chamber. A sound-generating module is positioned within the chamber. The module can include a housing containing (i) an airflow sensor configured to detect a pressure change in the chamber, (ii) a speaker configured to generate an audio output, and (iii) programmable circuitry operably coupled to the airflow sensor and the speaker. In operation, the airflow sensor can detect a pressure change in the chamber caused by a user squeezing the body of the toy, and can output a signal to the programmable circuitry indicating the pressure change. After receiving the signal indicating the pressure change, the programmable circuitry can drive the speaker to generate the audio output.

The present disclosure provides a lighting device for use with inflatable products, such as balloons. Specifically, the lighting device may be configured to utilize external audio to produce a pattern of light corresponding with the external audio. The lighting device is able to couple to a balloon to light up the interior of the balloon without the significant loss of gas or other inflating fluid from the balloon.

Embodiments of the present disclosure may include a method including assembling at least two building elements together. Embodiments may also include applying a stimulus to at least one of the at least two building elements, the stimulus being capable of changing a color of at least a portion of the one of the at least two building elements. In some embodiments, the at least two building elements may be assembled together prior to applying the stimulus.

Disclosed is a method for controlling a plurality of light-emitting devices. The method includes at least: inputting group information into a respective light-emitting device, the group information to be inputted corresponds to a seat in a venue, on which the respective light emitting device to be positioned; and selectively controlling illuminating or extinguishing of groups of light-emitting devices, in accordance with the group information, to present an image over the plurality of light-emitting devices positioned on seats in the venue of an event during a particular period of a group-performance presentation.

Disclosed is a method and device for directing a lighting effect that induces dynamic effects by using a masking layer. The method and device for directing a lighting effect may selectively control emission of a plurality of light emitting devices based on a masking layer, thereby inducing dynamic imaging effects such as moving images in a direction object, and may achieve the direction having a high degree of freedom by directing the direction position, size, or rotation of an object during a performance direction in a performance hall.

The invention concerns a disco ball with an outer skin (3) which on the outside is fitted with mirror pieces (6) and has an expandable inner structure (2) comprising an inflatable inner skin which in expanded state is spherical and holds the outer skin (3) in a ball shape, characterized in that the outer skin (3) has a plurality of approximately lenticular segments (4) which are arranged next to each other, and adjacent lenticular segments (4) are releasably connected together to form the outer skin (3), and the lenticular segments (4) are each fitted with mirror pieces (6) on the outside.
