dosplí

Dosplý is a term used in theoretical discussions of information design to denote a design principle in which a single message is presented through two parallel channels, such that each channel encodes the same core information but via different semiotic means. The approach aims to enhance comprehension, retention, and accessibility by leveraging multisensory processing.

In practice, dosplý might pair text with an accompanying set of visuals, such as diagrams or iconography, or pair spoken narration with synchronized on-screen graphics. The two streams are coordinated so that they reinforce each other, while each stream remains decodable if the other is partially incomplete. Dosplý emphasizes alignment and pacing to avoid dissonance between channels and to support varied cognitive preferences among audiences.

Origin and etymology: The term appears to have emerged in online discussions in the early 2020s; its exact origin is unclear. It resembles a coinage built from a prefix suggesting duality and a fragment suggested to imply splitting or duplication. The lack of a single canonical definition has led to several informal interpretations across design, education, and communication contexts.

Usage and reception: Dosplý is discussed in design theory and instructional materials as a way to improve comprehension for diverse audiences, including learners with different literacy levels or limited access to one channel. Critics note potential drawbacks, such as increased production costs, potential redundancy, and the risk of cognitive overload if not carefully balanced.
