We consider the modelling of a particular layout optimisation problem with cellular automata, namely, the LEGO construction problem. We show that this problem can be modelled easily with cellular automata, provided that cells are considered as clusters which can merge or split during each time step of the evolution of the cellular automaton. The LEGO… (More)
We discuss the design and implementation of a generic development platform for 3D virtual environments for autism spectrum disorder therapy tools. The platform is intended to enable researchers and therapists alike to quickly develop individual therapy software without having to resort to extensive software development. The platform includes specific… (More)
We describe the South African Sign Language Machine Translation project, and point out the role that the project is playing in the larger context of South African Sign Language and accessibility for the South African Deaf community.
The South African Sign Language Machine Translation System (SASL-MT System) takes as its input English text, and outputs an avatar signing the equivalent SASL. This paper describes our experiences to date with the implementation of a signing avatar, in the light of the specific requirements of Sign Language.
Systems that automatically process sign language rely on appropriate data. We therefore present the ATIS sign language corpus that is based on the domain of air travel information. It is available for five languages, English, German, Irish sign language, German sign language and South African sign language. The corpus can be used for different tasks like… (More)
We consider the problem of reducing the number of states of nondeterministic finite automata, and show how to encode the reduction as a Boolean satisfiability problem. This approach improves on previous work by reducing a more general class of automata. Experimental results show that it produces a minimal automaton in almost all cases and that the running… (More)
