machine can produce a certain output based on its input. Sometimes it may be required that the same input has to be used to generate the output. So in this machine, the distinction between input and output has been removed. Thus a common set of alphabets can be used for the Turing machine.

This paper introduces a Turing machine and pushdown automata simulators as a virtual environment for learning computational models and automata theory. The twofold contribution of this work is a novel use of modern technology to improve learning and a

** An Interaction Between User and an Augmented Reality System using A Generalized Finite State Automata and A Universal Turing Machine **

Most interactions between users and augmented reality system (ARS) are that user assigns a marker to ARS, and the ARS responds the marker. In this context, a marker is mapped to an ARSs response, or in general, an array of markers is mapped to an array of ARSs
