Making CNNs for Video Parsing Accessible
The ability to extract sequences of game events for high-resolution e-sport
games has traditionally required access to the game's engine. This serves as a
barrier to groups who don't possess this access. It is possible to apply deep
learning to derive these logs from gameplay video, but it requires
computational power that serves as an additional barrier. These groups would
benefit from access to these logs, such as small e-sport tournament organizers
who could better visualize gameplay to inform both audience and commentators.
In this paper we present a combined solution to reduce the required
computational resources and time to apply a convolutional neural network (CNN)
to extract events from e-sport gameplay videos. This solution consists of
techniques to train a CNN faster and methods to execute predictions more
quickly. This expands the types of machines capable of training and running
these models, which in turn extends access to extracting game logs with this
approach. We evaluate the approaches in the domain of DOTA2, one of the most
popular e-sports. Our results demonstrate our approach outperforms standard
backpropagation baselines.Comment: 11 pages, 6 figures, Foundations of Digital Games 201
Tangible user interfaces : past, present and future directions
In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research
Aesthetic choices: Defining the range of aesthetic views in interactive digital media including games and 3D virtual environments (3D VEs)
Defining aesthetic choices for interactive digital media such as games is a challenging task. Objective and subjective factors such as colour, symmetry, order and complexity, and statistical features among others play an important role for defining the aesthetic properties of interactive digital artifacts. Computational approaches developed in this regard also consider objective factors such as statistical image features for the assessment of aesthetic qualities. However, aesthetics for interactive digital media, such as games, requires more nuanced consideration than simple objective and subjective factors, for choosing a range of aesthetic features.
From the study it was found that the there is no one single optimum position or viewpoint with a corresponding relationship to the aesthetic considerations that influence interactive digital media. Instead, the incorporation of aesthetic features demonstrates the need to consider each component within interactive digital media as part of a range of possible features, and therefore within a range of possible camera positions. A framework, named as PCAWF, emphasized that combination of features and factors demonstrated the need to define a range of aesthetic viewpoints. This is important for improved user experience. From the framework it has been found that factors including the storyline, user state, gameplay, and application type are critical to defining the reasons associated with making aesthetic choices. The selection of a range of aesthetic features and characteristics is influenced by four main factors and sub-factors associated with the main factors.
This study informs the future of interactive digital media interaction by providing clarity and reasoning behind the aesthetic decision-making inclusions that are integrated into automatically generated vision by providing a framework for choosing a range of aesthetic viewpoints in a 3D virtual environment of a game. The study identifies critical juxtapositions between photographic and cinema-based media aesthetics by incorporating qualitative rationales from experts within the interactive digital media field. This research will change the way Artificial Intelligence (AI) generated interactive digital media in the way that it chooses visual outputs in terms of camera positions, field-view, orientation, contextual considerations, and user experiences. It will impact across all automated systems to ensure that human-values, rich variations, and extensive complexity are integrated in the AI-dominated development and design of future interactive digital media production
Conceptual Model of Game Aesthetics for Perceived Learning in Narrative Games
Narrative games may offer reasoning on players’ behaviour or make-believe on players’ personation as a pursuit to achieve specific goals. One of the goals is probably the intention to instil learning, which subconsciously provide information on the content of the game. However, there is lack of studies on the contribution of game aesthetics towards player’s perceived learning. By means of expert review, this article reports on conceptual model of game aesthetics towards perceived learning and the degree of importance of each attributes in perceived learning. Findings reveal that all experts agreed on the contribution of game aesthetics towards perceived learning. In additon, expert recommends three other factors that may contribute to learning: player’s motivation, learning content, and gameplay. Future work will continue to design and develop the game prototype and to investigate the relationship between game aesthetics and perceived learning
Multi-agent evolutionary systems for the generation of complex virtual worlds
Modern films, games and virtual reality applications are dependent on
convincing computer graphics. Highly complex models are a requirement for the
successful delivery of many scenes and environments. While workflows such as
rendering, compositing and animation have been streamlined to accommodate
increasing demands, modelling complex models is still a laborious task. This
paper introduces the computational benefits of an Interactive Genetic Algorithm
(IGA) to computer graphics modelling while compensating the effects of user
fatigue, a common issue with Interactive Evolutionary Computation. An
intelligent agent is used in conjunction with an IGA that offers the potential
to reduce the effects of user fatigue by learning from the choices made by the
human designer and directing the search accordingly. This workflow accelerates
the layout and distribution of basic elements to form complex models. It
captures the designer's intent through interaction, and encourages playful
discovery
