Dear colleagues, we are happy to announce the third episode of the UI-Engineering live talks, which are bimonthly seminars organised by the IFIP WG 2.7/13.4 and given by members or invited experts. This month, prof. Davide Spano will discuss techniques for supporting end users and novice programmers in creating XR environments, particularly for defining their interactive behaviour. The talk will be given on * September 28, 15:30 CET * Title: Easing XR Development for Novices and End Users Speaker: Davide Spano Link: https://youtube.com/live/mXDPX8CSEGQ?feature=share Abstract: This talk discusses a rule-based approach for enabling end-users and novice developers to define interactive behaviours in immersive eXtended Reality (XR) experiences. We start with a cultural and environmental preservation case study, introducing an authoring environment for first-person cinematographic video games based on 360-degree videos. Then, we extend the technique to the end-user configuration of Virtual Reality (VR) environments. The solution relies on template environments created by expert developers and an extensible library supporting their configuration by end-users through rules in a constrained natural language. Finally, we show how novice developers can benefit from the same rule-based representation, inspecting development examples defined through different XR toolkits. Our Unity Editor plugin can identify and describe interactions as rules, suggest similar interactions, and copy-paste interactions from examples, even if they use different toolkits. We conclude by discussing open questions and further extension of this research. -- [image: photo] Prof. Lucio Davide Spano Dipartimento di Matematica e Informatica Università di Cagliari Via Ospedale 72, 09124, Cagliari, Italy Tel: +39 070 675 8760 Website <https://www.unica.it/unica/page/it/luciod_spano> | RG <https://www.researchgate.net/profile/Lucio_Spano> | ORCHID <https://orcid.org/0000-0001-7106-0463>
