Research on enabling novice AR/VR developers has emphasized the need to lower the technical barriers to entry. This is often achieved by providing new authoring tools that provide simpler means to implement XR interactions through abstraction. However, novices are then bound by the ceiling of each tool and may not form the correct mental model of h...

Rule-based approaches have proven effective in automating smart homes, managing IoT sensors and devices, or expressing simple web-based workflows. More recently, rules have been used to define the behaviour of point-and-click games and virtual reality experiences. In this paper, we propose an analysis of the first dataset of point-and-click games d...

This paper proposes a solution for supporting end users in configuring Virtual Reality environments by exploiting reusable templates created by experts. We identify the roles participating in the environment development and the means for delegating part of the behaviour definition to the end users. We focus in particular on enabling end users to de...

This paper presents the early stages of my PhD work, which consists of a solution for supporting end users in configuring eXtended Reality (XR) environments, exploiting templates created by experts. The proposed approach is based on an EUD [8] methodology for solving this problem, employing Event-Condition-Action (ECA) rule-language defining the en...

In this paper, we investigate the effects of including a conversational intelligent agent for helping end user developers in defining the behaviour of point-and-click games through event-condition action rules. We discuss the rule support in a web-based authoring environment, together with the design and the implementation of the agent in the form...

We present and explore the fruitfulness of “first-person cinematographic videogames,” a game model we have devised for the promotion of cultural, environmental, and territorial heritage. To support and foster the development of these type of games, we have developed a Web-based user-friendly authoring environment, extensively presented in the artic...

In this paper we discuss the design and implementation of a preliminary Mixed Reality interface for Microsoft Hololens, supporting medical records retrieval and navigation. The goal is to ease common activities in the dynamic clinical context, using facial recognition and multimodal commands for accessing medical records on the fly through a free-h...
