    Product development consists of two stages: geometrical modeling to define the product's shape, followed by mechanical simulation to verify the design specification and ensure the product's structural integrity. New demands on product design cannot be met using this traditional approach to product development where these two stages remain distinct. Thus, making simulation and analysis pervasive th...

    Subtle phenomena rooted in our body dynamics affect the reactive and evolutive parts of every human interaction. The authors' decision model allows for adaptive physical interactions between a human and a virtual agent. This article presents an evaluation of that model in terms of agent believability, the user's feeling of co-presence, and overall game experience. The results show that the model c...

  • Data-Driven Approach to Synthesizing Facial Animation Using Motion Capture

    Producing cartoon animations is a laborious task, and there is a distinct lack of automatic tools to help animators, particularly with creating facial animation. The proposed method uses real-time video-based motion tracking to generate facial motion as input and then matches it to existing hand-created animation curves. The synthesized animations can then be refined and polished by an animator, s... View full abstract»

  • Fast Neural Style Transfer for Motion Data

    Automating motion style transfer can help save animators time by allowing them to produce a single set of motions, which can then be automatically adapted for use with different characters. The proposed fast, efficient technique for performing neural style transfer of human motion data uses a feed-forward neural network trained on a large motion database. The proposed framework can transform the s... View full abstract»

    A growing body of evidence shows that virtual audiences are a valuable tool in the treatment of social anxiety, and recent works show that it also a useful in public-speaking training programs. However, little research has focused on how such audiences are perceived and on how the behavior of virtual audiences can be manipulated to create various types of stimuli. The authors used a crowdsourcing ... View full abstract»

  • Evaluating and Optimizing Evacuation Plans for Crowd Egress

    Evacuation planning is an important and difficult task in building design. The proposed framework can identify optimal evacuation plans using decision points, which control the ratio of agents that select a particular route at a specific spatial location. The authors optimize these ratios to achieve the best evacuation based on a quantitatively validated metric for evacuation performance. This met... View full abstract»

    Education research has shown that instructor gestures can help capture, maintain, and direct the student's attention during a lecture as well as enhance learning and retention. Traditional education research on instructor gestures relies on video stimuli, which are time consuming to produce, especially when gesture precision and consistency across conditions are strictly enforced. The proposed sys... View full abstract»

    Corrective lenses introduce distortion caused by the refraction effect, which changes the wear's appearance. To give users a more realistic experience, a virtual try-on system for prescription eyeglasses modifies an input video and virtually inserts prescription eyeglasses, producing an output similar to a virtual mirror. The proposed system generates a 3D representation of the corrective lenses m... View full abstract»

    Optical motion-capture systems can be used to animate characters in real time based on human demonstrations. However, most approaches do not consider the detailed finger movements necessary for object manipulation. The proposed online motion-capture framework encourages natural motions by automatically guiding the avatar's motion toward the desired behavior based on a set of captured reference mot...

    There is little doubt that having a theoretic foundation will benefit the field of visualization, including its main subfields. Because there has been a substantial amount of work on taxonomies and conceptual models in the visualization literature and some recent work on theoretic frameworks, such a theoretic foundation is not a foolish or impractical ambition. This article asks, “How can w... View full abstract»
