We propose conversational interfaces as a convenient and complementary way for users to explore OSGi-based software architectures in immersive Augmented Reality (AR). By providing a conversational interface we aim to remedy some peculiarities of AR devices, but also enhancing the exploration task at hand. We exemplify a use case and sketch how different user utterances can be used to retrieve information about the to-be-explored OSGi-based software architecture. We identify crucial components such as natural language generation and intent recognition which are required to implement the user story and we outline the status of our implementation.

Exploring of software architectures with software visualization in Augmented Reality (AR) is possible with different interaction methods, such gesture, gaze, and speech. For interaction with speech (i.e., natural language), we present an architecture and an implementation of conversational interfaces for the Microsoft HoloLens device. We aim to remedy some peculiarities of AR devices, but also enhancing the exploration task at hand. To implement the conversational interface different natural language processing (NLP) components such as natural language generation and intent recognition are typically required. Our proposed architecture integrates conversational components with the AR-based software visualization. We describe its implementation based on different user utterances, where the system provides information about the to-be-explored component-based software architecture in the form of adjusted visualizations and speech-based results. We apply out tool to explore OSGi-based software architectures.
