Long Term Behavior

There is an attention shift within the gaming industry toward more natural (long-term) behavior of nonplaying characters (NPCs). Multiagent system research offers a promising technology to implement cognitive intelligent NPCs. However, the technologies used in game engines and multiagent platforms are not readily compatible due to some inherent differences of concerns. Where game engines focus on real-time aspects and thus propagate efficiency and central control, multiagent platforms assume autonomy of the agents. Increased autonomy and intelligence may offer benefits for a more compelling gameplay and may even be necessary for serious games. However, it raises problems when current game design techniques are used to incorporate state-of-the-art multiagent system technology. In this paper, we will focus on three specific problem areas that arise from this difference of view: synchronization, information representation, and communication. We argue that the current attempts for integration still fall short on some of these aspects. We show that to fully integrate intelligent agents in games, one should not only use a technical solution, but also a design methodology that is amenable to agents. The game design should be adjusted to incorporate the possibilities of agents early on in the process.

Abstract Interventions using exercise video games, or exergames, have shown short-term cognitive and physical benefits to older adults, though long-term effects are less promising. Enjoyment of exergames may promote exergame use after the intervention period, though little work has examined older adults’ views of exergames before and after gameplay experience. We invited 20 older adults between 65 and 84 years of age (M=73.30, SD=5.95) to play two Xbox Kinect games, Just Dance and Kinect Sports Rivals, for twenty minutes. In our presentation, we will present qualitative and quantitative findings of this pilot study, including findings that older adults reported that they were not likely to play similar exergames in the future and that they did not find the exergames to be more fun compared to other ways of exercising. We will discuss implications for game design and research relevant to game developers, manufacturers, and researchers. Part of a symposium sponsored by Technology and Aging Interest Group.

Mapping Theory

In order to predict the long term behavior of nonlinear dynamical systems the generalized cell mapping is an efficient and powerful method for numerical analysis. For this reason it is of interest to know under what circumstances dynamical quantities of the generalized cell mapping (like persistent groups, stationary densities, …) reflect the dynamics of the system (attractors, invariant measures, …). In this article we develop such connections between the generalized cell mapping theory and the theory of nonlinear dynamical systems. We prove that the generalized cell mapping is a discretization of the Frobenius–Perron operator. By applying the results obtained for the Frobenius–Perron operator to the generalized cell mapping we outline for some classes of transformations that the stationary densities of the generalized cell mapping converges to an invariant measure of the system. Furthermore, we discuss what kind of measures and attractors can be approximated by this method.

Branding Strategies

The gaming industry has seen dramatic change and expansion with the emergence of ‘casual’ games that promote shorter periods of gameplay. Free to download, but structured around micropayments, these games raise the complex relationship between game design and commercial strategies. Although offering a free gameplay experience in line with open access philosophies, these games also create systems that offer control over the temporal dynamics of that experience to monetize player attention and inattention. This article will examine three ‘freemium’ games, Snoopy Street Fair, The Simpsons’ Tapped Out and Dragonvale, to explore how they combine established branding strategies with gameplay methods that monetize player impatience. In examining these games, this article will ultimately indicate the need for game studies to interrogate the intersection between commercial motivations and game design and a broader need for media and cultural studies to consider the social, cultural, economic and political implications of impatience.

Long Term Behavior

This paper is devoted to the long-term behavior of nonautonomous random lattice dynamical systems with nonlinear diffusion terms. The nonlinear drift and diffusion terms are not expected to be Lipschitz continuous but satisfy the continuity and growth conditions. We first prove the existence of solutions, and establish the existence of a multi-valued nonautonomous cocycle. We then show the existence and uniqueness of pullback attractors parameterized by sample parameters. Finally, we establish the measurability of this pullback attractor by the method based on the weak upper semicontinuity of the solutions.

Hydration Kinetics

A jointed plain concrete pavement represents a reliable, historically proven technical solution for highly loaded roads, highways, airports and other industrial surfaces. Excellent resistance to permanent deformations (rutting) and also durability and maintenance costs play key roles in assessing the economic benefits, rehabilitation plans, traffic closures, consumption and recycling of materials. In the history of concrete pavement construction, slow-to-normal hardening Portland cement was used in Czechoslovakia during the 1970s-1980s. The pavements are being replaced after 40-50 years of service, mostly due to vertical slab displacements due to missing dowel bars. However, pavements built after 1996 used rapid hardening cements, resulting in long-term surface cracking and decreased durability. In order to build durable concrete pavements, slower hardening slag-blended binders were designed and tested in the restrained ring shrinkage test and in isothermal calorimetry. Corresponding concretes were tested mainly for the compressive/tensile strength evolution and deicing salt-frost scaling to meet current specifications. The pilot project was executed on a 14 km highway, where a unique temperature-strain monitoring system was installed to provide long-term data from the concrete pavement. A thermo-mechanical coupled model served for data validation, showing a beneficial role of slower hydration kinetics. Continuous monitoring interim results at 24 months have revealed small curling induced by drying and the overall small differential shrinkage of the slab.

BACKGROUND The design of Virtual Reality Serious Games (VR-SG) is a subject still developing. One of its open developments is the definition of metrics to evaluate the fun and learning result. In this way, weaknesses and strengths in the design of serious games can be found for future works in this research field. OBJECTIVE This paper aims to create a metric that can be used to rate the gameplay of VR-SG. This metric’s novelty allows to evaluate the different fun and learning features and give them a quantitative rating. A study case shows the capability of implementing this evaluation to identify strengths and weaknesses of VR-SGs. METHODS The new VR-SG metric is developed on the basis of the Mechanics, Dynamics and Aesthetic (MDA) framework but including User Experience (UX) elements and adapting them to VR-SG. This metric includes 1) UX aspects: VR-headsets, training tutorials and interactive adaptions to avoid VR inconveniences; and 2) MDA aspects: exclusive VR audiovisual elements and its aesthetics interactions. RESULTS The selected indie serious game is Hellblade, developed to raise awareness about the difficulties of people suffering from psychosis with two versions: one for 2D-screens and the other for VR devices. The comparison of metric´s scores for both versions shows: 1) some VR dynamics increase the gameplay impact and therefore, the educational capacity; and 2) flaws in game design where the scores drop down. Some of these flaws are: reduced number of levels, missions and items, lack of a tutorial to enhance usability and lack of strategies and rewards in the long-term to increase motivation. CONCLUSIONS This metric allows to identify the elements of the gameplay and UX that are necessary to learn in VR experiences. The study case shows this research is useful to evaluate the educational utility of VR-SG. Further works will analyze VR applications to synthetize every game element influencing its intrinsic sensations. CLINICALTRIAL The trials have not been registered, as testing for this metric has not involved people with mental conditions or addressed other medical applications. Hellblade is a commercial video game that anyone can purchase and play. The trials have been carried out to obtain results on the gaming experience of different people in relation to the educational purpose of raising awareness of psychosis.
