Dialog Designs in Virtual Drama: Balancing Agency and Scripted Dialogs [chapter]

Edward Chao-Chun Kao, Von-Wun Soo
2012 Lecture Notes in Computer Science  
The scripts for actors consist of two parts: movements and dialogs, however, the dialogs are insufficiently addressed in current research of story generation, thereby limiting the generated stories.  ...  In addition, we introduce the manner in which agents may improvise scripted dialogs by selecting various courses of actions.  ...  Virtual actors: virtual agents may be implemented by various methods in virtual environments and intended to act as characters in the play.  ...

An LLVM-based decoder for MPEG Reconfigurable Video Coding

J. Gorin, M. Wipliez, J. Piat, F. Preteux, M. Raulet
2010 2010 IEEE Workshop On Signal Processing Systems  
This methodology aims at producing Abstract Decoder Models (ADMs) of MPEG decoders as dataflow programs described in RVC-CAL Actor Language (RVC-CAL) [1].  ...  This paper presents new mechanisms based on the Low Level Virtual Machine (LLVM) capacities that allow the conception of the first decoder able to dynamically instantiate an RVC decoder description.  ...  This property allows each actor of a dataflow model to be unbound to its environment and thus to be easily used in others.  ...

An integrated environment for HW/SW co-design based on a CAL specification and HW/SW code generators

2009 2009 IEEE International Symposium on Circuits and Systems  
Each actor executes in a sequence of steps, during which it can (1) consume input tokens, (2) produce output tokens, (3) modify its own local state.  ...  The demonstration focuses on the capability of the co-design environment to automatically build an executable heterogeneous system implementation running on a platform composed by a processor and a FPGA  ...  In this way the actors mapped as HDL code on the FPGA can execute their tasks when they receive the tokens via the virtual channels established by the API.  ...
