This article describes SHPE (Simple Hierarchical Planning Engine), a hierarchical task network planning system designed to generate dynamic behaviours for real-time video games. SHPE is based on a combination of domain compilation and procedural task application/ decomposition techniques in order to compute plans in a very short time-frame. The planner has been able to return relevant plans in less than three milliseconds for several problem instances of the SimpleFPS planning domain. © Springer International Publishing Switzerland 2014.

In the context of using an Unmanned Aerial Vehicle (UAV) in hostile environments, gestures allow to free the operator of bulky control interfaces. Since a navigation plan is defined before the mission, only a few commands have to be activated during the mission. This allows a gestural symbolic interaction that maps commands to a set of gestures. Nevertheless, as gestures are not universal, this asks the question of choosing the proper gestures that are easy to learn memorize and perform. We propose a four step methodology for eliciting a gestural vocabulary, and apply it to this use case. The methodology consists of 4 steps: (1) collecting gestures through user creativity sessions, (2) extracting candidate gestures to build a catalogue, (3) electing the gesture vocabulary and (3) evaluating the non-ambiguity of it. We then discuss the relevance of the GV. Copyright 2015 © ACM. Source
