Advances in machine translation for sign language: approaches, limitations, and challenges

Abstract: Sign languages are used by the deaf community around the globe to communicate with one another. These are gesture-based languages where a deaf person performs gestures using hands and facial expressions. Every gesture represents a word or a phrase in the natural language. There are more than 200 different sign languages in the world. In order to facilitate the learning of sign languages by the deaf community, researchers have compiled sign language repositories comprising of gestures. Similarly, algorithms have been proposed to translate the natural language into sign language, which is subsequently converted into gestures using avatar technology. On the other hand, several different approaches for gesture recognition have also been proposed in the literature, many of which use specialized hardware. Similarly, cell phone applications have been developed for learning and translation of sign languages. This article presents a systematic literature review of these multidisciplinary aspects of sign language translation. It provides a detailed analysis of carefully selected 147 high-quality research articles and books related to the subject matter. Specifically, it categorizes different approaches used for each component, discusses their theoretical foundations, and provides a comparative analysis of the proposed approaches. Lastly, open research challenges and future directions for each facet of the sign language translation problem have been discussed. To the best of our knowledge, this is the first comprehensive survey on sign language translation that discusses state-of-the-art research from multi-disciplinary perspectives.

Tongues as a Sign: Towards a Sacramental Understanding of Pentecostal Experience

Abstract: Simon Tugwell observed that most classical Pentecostals' do not regard baptism and the eucharist as \"sacramental\" in significance. Instead of functioning as visible signs of God's presence to save, the principle sacraments of baptism and the eucharist among Pentecostals appeared to Tugwell to be tied more closely with human acts of repentance and testimonies of faith. Of significant interest, however, is Tugwell's recognition of the \"sacramental\" character of Pentecostal speaking in tongues. He noted that, for Pentecostals, glossolalia signified God's presence here and now. Rather than representing mere emotionalism, tongues made God present for Pentecostals in a special, audibly identifiable way. As a Catholic, Tugwell felt most at home in this aspect of Pentecostal worship and speculated that tongues might provide a fruitful point of departure for future Pentecostal/Catholic

Human–computer interaction viewed as pseudo-communication

Abstract: Semiotics is considered fundamental to an understanding of human–computer interaction, and of all computer artifacts. Informatics should therefore be viewed as technical semiotics (or semiotics engineering). In particular, interaction between human and computer is characterized by features of communication, a sort of communication, however, that lacks decisive communicative features. It must be identified as a process of pseudo-communication. Interaction is viewed as the coupling of two autonomous processes: a sign process (carried out by the human user) and a signal process (carried out by the computer). Software appears as a semiotic entity in a duplicate way: calculated and calculating, i.e. both as a result and agent of calculations. This dialectics characterizes the class of signs on the computer medium. Problems of software design (functionality and usability design) are specific problems of the coupling of sign and signal processes.
