Dear Esteemed Colleagues,

We are a research group of the Computer Science Department and Polin Laboratory at University of Turin. We need your contribution to test a dialogue system for exploring finite automata with the accessibility goal in mind.

*Introducing the NoVAGraphS Research Experiment*

Our research team comprising Alessandro Mazzei, Luca Anselma, Pier Felice Balestrucci, Cristian Bernareggi, Elisa Di Nuovo and Manuela Sanguinetti, is thrilled to extend a heartfelt invitation to individuals with a basic knowledge of *English* and* finite state automata*. We need your valuable insights to evaluate our prototype system designed to enhance the accessibility of automata, a graphical structure usually taught in Computer Science courses which is not yet fully accessible for individuals with visual impairments.

*What would you expect?*

- You will interact with a prototype dialogue system using a web interface to explore a simple automaton. - Moreover, you will explore another simple automaton using a state transition table. - Finally, we will ask you some questions to assess your understanding of the two automata and collect your precious feedback on the usability of the dialogue system. Rest assured, any personal information collected will remain completely anonymous. - It will take approximately 15 minutes (standard deviation = 5 minutes :D).

*Interested in participating or needing more information to decide?*

In both cases, please contact Pier at the following email address: pierfelice.balestrucci[at]unito.it

Kind regards, Elisa Di Nuovo on behalf of NoVAGraphS Research Group
