The evolution of antibiotic resistance among bacteria threatens our continued ability to treat infectious diseases. The need for sustainable strategies to cure bacterial infections has never been greater. So far, all attempts to restore susceptibility after resistance has arisen have been unsuccessful, including restrictions on prescribing [1] and(More)
Researchers demand much from their embodied conversational agents (ECAs), requiring them to be both lifelike , as well as responsive to events in an interactive setting. We find that a flexible combination of animation approaches may be needed to satisfy these needs. In this paper we present SmartBody, an open source modular framework for animating ECAs in(More)
This paper presents a novel whole-body analytical inverse kinematics (IK) method integrating collision avoidance and customizable body control for animating reaching tasks in real-time. Whole-body control is achieved with the interpolation of pre-designed key body postures, which are organized as a function of the direction to the goal to be reached. Arm(More)
Editing recorded motions to make them suitable for different sets of environmental constraints is a general and difficult open problem. In this paper we solve a significant part of this problem by modifying full-body motions with an interactive randomized motion planner. Our method is able to synthesize collision-free motions for specified linkages of(More)
Real-time 3D graphics are being extensively used to build interactive virtual environments for a number of different applications. In many situations, virtual objects are required to exhibit complex behaviors, and the use of a versatile behavioral programming methodology is required. This paper presents a feature modeling approach to define behavioral(More)
We present new techniques that use motion planning algorithms based on probabilistic roadmaps to control 22 degrees of freedom (DOFs) of human-like characters in interactive applications. Our main purpose is the automatic synthesis of collision-free reaching motions for both arms, with automatic column control and leg flexion. Generated motions are(More)
We describe the design of a modular system for untethered real-time kinematic motion capture using sensors with inertial measuring units (IMUs). Our system is comprised of a set of small and lightweight sensors. Each sensor provides its own global orientation (3 degrees of freedom) and is physically and computationally independent, requiring only external(More)
This paper shows a new approach to model and control interactive objects for simulations with virtual human agents when real time interactivity is essential. A general conceptualization is made to model objects with behaviors that can provide: information about their functionality, changes in appearance from parameterized deformations, and a complete plan(More)
