The e-Lite research group will participate at the ACM Conference on Human Factors in Computing Systems (CHI), one of the most important conference in the field of human-computer interaction. The 2018 edition will take place in Montréal, Canada, from the 21th to the 26th of April.

Alberto Monge Roffarello will present a paper on Tuesday (April, 24) about end-user debugging for the IoT.

In particular, the paper is entitled A Debugging Approach for Trigger-Action Programming, and it introduces a novel end users debugging approach for trigger-action rules (i.e., if something happens, then do something else") in the IoT.

The goal of the work, in fact, is to assists end users during the composition of trigger-action rules by highlighting possible problems that the rules may generate, and allowing their step-by-step simulation, if needed. The approach presented in the paper is based on Semantic Web ontologies and Petri Nets, and it has been implemented in a software tool as well as preliminary evaluated in a user study. Results suggest that the approach successfully helps users in understanding and identifying problems in trigger-action rules.
