Automatic theorem proving consists of proving mathematical theorems by means of computer programs. Depending on the logic used, the process of proving a formula is not computable. Moreover, depending of the deductive system applied to, the search for a proof can involve the application of long sequences of axioms and inference rules, reinforcing the need of human intervention in the proof process. Such systems are known as interactive theorem provers or proof assistants. In a typical scenario, the user interacts with the prover through a graphical interface, usually a desktop application. Recently, however, applications like those started to be delivered to users through the web. This way of software deployment avoids that final users have to deal with complex activities like prover installation and configuration and allows this user to access the system from different machines with a simple Internet connection. In this research we study the use of web as a platform for interactive theorem proving environments construction. Our purpose is to study some interaction models between user and automated proof environments and verify how these models can be adapted to work as a web application. As a result we show a graphical tool for visualization and direct manipulation of formal proofs on web to work as an alternative interface between user and proving machines.
