Interaction sequences can be used as an abstraction of an interactive system. We can use such models to consider or verify properties of a system for testing purposes. However, interaction sequences have the potential to become unfeasibly long, leading to models which are intractable. We propose a method of reducing the state space of such sequences using the self-containment property. This allows us to hide (and subsequently expand) some of the model describing parts of the system not currently under consideration. Interaction sequences and their models can therefore be used to control the state space size of the models we create as an abstraction of an interactive system.

Writing mathematical contents on digital format is more common every day. The usual method is to use WYSIWYG (What You See Is What You Get) equation editors included in mainstream text editors. However, this method requires a good deal of interaction with formula templates and the use of a pointing device. While this type of equation editors is accessible to users without visual disabilities, they present barriers for users with visual disability (UWVDs). Keyboard-based equation editors should promote not only inclusion but also an acceptable performance for sighted and non-sighted users. In this article, we analyze the efficiency of the typing protocol of the Algebra Editor, an accessible keyboard-based equation editor prototype, with sighted users. Results suggest that the protocol allows typing approximately 60 characters per minute. We also analyze the type and frequency of errors made by participants and suggest improvements to the protocol, derived from the findings. These results can be used as a reference to compare the efficiency of the protocol with non-sighted users and with other equation editors in future studies.
