Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for the selection, provision and display of one or more digital components during display of content. Methods can include identifying a plurality of digital components that can be presented on the client device. A maximum number of digital components that can be presented in a slot of a content and the time duration of the slot is determined. For each digital component a score is generated based on the duration, position requirement and the number of times the digital component is available for provision within the slot is generated. A first set of digital component is selected based on the scores and provided to the client device.

Abstract: A multisensory learning system incorporates a plurality of connectable multisensory elements. Each multisensory element may be a piece, a tile, or a block, and includes a surface containing a single character recessed into the surface to form a track. The track may guide a user's finger into the recessed area containing a tactile pattern at a base thereof. The tactile pattern heightens the sensory perception of the character to aid in learning. Each multisensory element is capable of being attached to another multisensory element in order to string characters together. In use, tracing of the tactile pattern of the character triggers the combination of sensations of kinesthetic learning through the motion of tracing and tactile learning through the feel of the tactile pattern in the recessed characters. This may be combined with audiovisual learning by looking at the character(s) and speaking the name.
