TL;DR: Data acquisition, feature extraction and classification methods employed for the analysis of sign language gestures are examined and the overall progress toward a true test of sign recognition systems--dealing with natural signing by native signers is discussed.
Abstract: Research in automatic analysis of sign language has largely focused on recognizing the lexical (or citation) form of sign gestures as they appear in continuous signing, and developing algorithms that scale well to large vocabularies. However, successful recognition of lexical signs is not sufficient for a full understanding of sign language communication. Nonmanual signals and grammatical processes which result in systematic variations in sign appearance are integral aspects of this communication but have received comparatively little attention in the literature. In this survey, we examine data acquisition, feature extraction and classification methods employed for the analysis of sign language gestures. These are discussed with respect to issues such as modeling transitions between signs in continuous signing, modeling inflectional processes, signer independence, and adaptation. We further examine works that attempt to analyze nonmanual signals and discuss issues related to integrating these with (hand) sign gestures. We also discuss the overall progress toward a true test of sign recognition systems?dealing with natural signing by native signers. We suggest some future directions for this research and also point to contributions it can make to other fields of research. Web-based supplemental materials (appendicies) which contain several illustrative examples and videos of signing can be found at www.computer.org/publications/dlib.

TL;DR: The semiotic basis for the claim that transmediation increases students' opportunities to engage in generative and reflective thinking is explored and generative potential is illustrated.
Abstract: The emerging shift from transmissionto inquiry-oriented models of teaching and learning implies that students need more than words to learn. Transmediation, the act of translating meanings from one sign system to another, increases students' opportunities to engage in generative and reflective thinking because learners must invent a connection between the two sign systems, as the connection does not exist a priori. In this article I explore the semiotic basis for this claim and illustrate the generative potential of transmediation.

TL;DR: Deaf children who are unable to acquire oral language naturally and who are not exposed to a standard manual language can spontaneously develop a structured sign system that has many of the properties of natural spoken language.
Abstract: Deaf children who are unable to acquire oral language naturally and who are not exposed to a standard manual language can spontaneously develop a structured sign system that has many of the properties of natural spoken language. This communication system appears to be largely the invention of the child himself rather than of the caretakers.

TL;DR: It is shown that the quality of representations is closely related to the preservation properties of semiotic morphisms; these measures of quality also provide the orderings needed by the category theoretic formulation of blending.
Abstract: This paper introduces a new approach to user interface design and other areas, called algebraic semiotics. The approach is based on a notion of sign, which allows complex hierarchical structure and incorporates the insight (emphasized by Saussure) that signs come in systems, and should be studied at that level, rather than individually. A user interface can be considered as a representation of the underlying functionality to which it provides access, and thus user interface design can be considered a craft of constructing such representations, where both the interface and the underlying functionality are considered as (structured) sign systems. In this setting, representations appear as mappings, or morphisms, between sign systems, which should preserve as much structure as possible. This motivates developing a calculus having systematic ways to combine signs, sign systems, and representations. One important mode of composition is blending, introduced by Fauconnier and Turner; we relate this to certain concepts from the very abstract area of mathematics called category theory. Applications for algebraic semiotics include not only user interface design, but also cognitive linguistics, especially metaphor theory and cognitive poetics. The main contribution of this paper is the precision it can bring to such areas. Building on an insight from computer science, that discrete structures can be described by algebraic theories, sign systems are defined to be algebraic theories with extra structure, and semiotic morphisms are defined to be mappings of algebraic theories that (to some extent) preserve the extra structure. As an aid for practical design, we show that the quality of representations is closely related to the preservation properties of semiotic morphisms; these measures of quality also provide the orderings needed by our category theoretic formulation of blending.
