Ascending from the valley: Can state-of-the-art photorealism avoid the uncanny?
(2021)Advancements in real-time rendering technology have continued to develop rapidly over the course of the last decade. Consequently, human likenesses have been represented virtually with increasingly impressive detail. ... -
The effect of gender and attractiveness of motion on proximity in virtual reality
(2020)In human interaction, people will keep different distances from each other depending on their gender. For example, males will stand further away from males and closer to females. Previous studies in virtual reality (VR), ... -
The effect of multimodal emotional expression and agent appearance on trust in human-agent interaction
(2019)Emotional expressivity can boost trust in human-human and human-machine interaction. As a multimodal phenomenon, previous research argued that a mismatch in the expressive channels provides evidence of joint audio-video ... -
Evalu-light: A practical approach for evaluating character lighting in real-time
(2020)The demand for cartoon animation content is on the rise, driven largely by social media, video conferencing and virtual reality. New content creation tools and the availability of open-source game engines allow characters ... -
Eye-catching Crowds: Saliency based selective variation
(2009)Populated virtual environments need to be simulated with as much variety as possible. By identifying the most salient parts of the scene and characters, available resources can be concentrated where they are needed most. ... -
How to train your dog: Neural enhancement of quadruped animations
(2021)Creating realistic quadruped animations is challenging. Producing realistic animations using methods such as key-framing is time consuming and requires much artistic expertise. Alternatively, motion capture methods have ... -
Investigating perceptually based models to predict importance of facial blendshapes
(2020)Blendshape facial rigs are used extensively in the industry for facial animation of virtual humans. However, storing and manipulating large numbers of facial meshes is costly in terms of memory and computation for gaming ... -
Investigating the use of recurrent motion modelling for speech gesture generation
(2018)The growing use of virtual humans demands generating increasingly realistic behavior for them while minimizing cost and time. Gestures are a key ingredient for realistic and engaging virtual agents and consequently automatized ... -
Methodology for Building Synthetic Datasets with Virtual Humans
(2020)Recent advances in deep learning methods have increased the performance of face detection and recognition systems. The accuracy of these models relies on the range of variation provided in the training data. Creating a ... -
Model for predicting perception of facial action unit activation using virtual humans
(2021)Blendshape facial rigs are used extensively in the industry for facial animation of virtual humans. However, storing and manipulating large numbers of facial meshes (blendshapes) is costly in terms of memory and computation ... -
Perceptual evaluation of level of detail clothing for virtual humans
(2006)Recent developments in crowd simulation have allowed thousands of characters to be rendered in real-time. Usually this is achieved through the use of Level of Detail (LOD) models for the individuals in the crowd. ... -
Seeing is Believing: Body Motion Dominates in Multisensory Conversations
(2010)In many scenes with human characters, interacting groups are an important factor for maintaining a sense of realism. However, little is known about what makes these characters appear realistic. In this paper, we investigate ... -
Survival at the museum: A cooperation experiment with emotionally expressive virtual characters
(2018)Correctly interpreting an interlocutor's emotional expression is paramount to a successful interaction. But what happens when one of the interlocutors is a machine? The facilitation of human-machine communication and ... -
Sympathy for the digital: influence of synthetic voice on affinity, social presence and empathy for photorealistic virtual humans
(2022)In this paper, we investigate the effect of a realism mismatch in the voice and appearance of a photorealistic virtual character in both immersive and screen-mediated virtual contexts. While many studies have investigated ... -
Understanding the Predictability of Gesture Parameters from Speech and their Perceptual Importance
(2020)Gesture behavior is a natural part of human conversation. Much work has focused on removing the need for tedious hand-animation to create embodied conversational agents by designing speech-driven gesture generators. However, ... -
Virtual Shapers & Movers: Form and Motion affect Sex Perception
(2007)An experiment to determine factors that influence the perceived sex of virtual characters was conducted. Four different model types were used: highly realistic male and female models, an androgynous character, and a point ...
