An Extendable Multiagent Model for Behavioural Animation
This paper presents a framework for visually
simulating the behaviour of actors in virtual environments.
In principle, the environmental interaction
follows a cyclic processing of perception,
decision, and action. As natural life-forms
perceive their environment by active sensing,
our approach also tends to let the artificial actor
actively sense the virtual world. This allows
us to place the characters in non-preprocessed
virtual dynamic environments, what we call
generic environments. A main aspect within
our framework is the strict distinction between
a behaviour pattern, that we term model, and
its instances, named characters, which use the
pattern. This allows them sharing one or more
behaviour models. Low-level tasks like sensing
or acting are took over by so called subagents,
which are subordinated modules extendedly
plugged in the character. In a demonstration
we exemplarily show the application of
our framework. We place the same
character in different environments and let it
climb and descend stairs, ramps and hills autonomously.
Additionally the reactiveness for
moving objects is tested. In future, this approach
shall go into action for a simulation of an urban
environment
Open Medical Gesture: An Open-Source Experiment in Naturalistic Physical Interactions for Mixed and Virtual Reality Simulations
Mixed Reality (MR) and Virtual Reality (VR) simulations are hampered by
requirements for hand controllers or attempts to perseverate in use of
two-dimensional computer interface paradigms from the 1980s. From our efforts
to produce more naturalistic interactions for combat medic training for the
military, USC has developed an open-source toolkit that enables direct hand
controlled responsive interactions that is sensor independent and can function
with depth sensing cameras, webcams or sensory gloves. Natural approaches we
have examined include the ability to manipulate virtual smart objects in a
similar manner to how they are used in the real world. From this research and
review of current literature, we have discerned several best approaches for
hand-based human computer interactions which provide intuitive, responsive,
useful, and low frustration experiences for VR users.Comment: AHFE 202
A Survey of Deep Learning in Sports Applications: Perception, Comprehension, and Decision
Deep learning has the potential to revolutionize sports performance, with
applications ranging from perception and comprehension to decision. This paper
presents a comprehensive survey of deep learning in sports performance,
focusing on three main aspects: algorithms, datasets and virtual environments,
and challenges. Firstly, we discuss the hierarchical structure of deep learning
algorithms in sports performance which includes perception, comprehension and
decision while comparing their strengths and weaknesses. Secondly, we list
widely used existing datasets in sports and highlight their characteristics and
limitations. Finally, we summarize current challenges and point out future
trends of deep learning in sports. Our survey provides valuable reference
material for researchers interested in deep learning in sports applications
