Pathfinder:a performance-game for the augmented drum-kit

Pathfinder is a performance-game for solo drummer, exploring the synergies between multiple contemporary creative practices. The work navigates between music composition, improvisation, projection/light art and game art. At its heart lies a bespoke electro-acoustic instrument, the augmented drum-kit, used not only to provide the sonic content of the work in real-time, but also as a highly expressive game controller that interacts with an instrument-specific game. The musical instrument offers a much wider range of expressive possibilities, control and tactile feedback in comparison to a traditional general-purpose game controller, and as a result it affords a more diverse and nuanced game play performance. Live electronics, lights, projections and the drum-kit all make up the performance-game’s universe, within which the performer has to explore, adapt, navigate and complete a journey

It’s not the model that doesn’t fit, it’s the controller! The role of cognitive skills in understanding the links between natural mapping, performance, and enjoyment of console video games

This study examines differences in performance, frustration, and game ratings of individuals playing first person shooter video games using two different controllers (motion controller and a traditional, pushbutton controller) in a within-subjects, randomized order design. Structural equation modeling was used to demonstrate that cognitive skills such as mental rotation ability and eye/hand coordination predicted performance for both controllers, but the motion control was significantly more frustrating. Moreover, increased performance was only related to game ratings for the traditional controller input. We interpret these data as evidence that, contrary to the assumption that motion controlled interfaces are more naturally mapped than traditional push-button controllers, the traditional controller was more naturally mapped as an interface for gameplay

On Cheating and Whistle-Blowing

We study the role of whistle-blowing in the following inspection game. Two agents who compete for a valuable prize can either behave legally or illegally. After the competition, a controller investigates the agents' behavior. This control game has a unique equilibrium in mixed strategies. We then add a whistle-blowing stage, where the controller asks the loser to blow the whistle. This extended game has a unique perfect Bayesian equilibrium in which only a cheating loser accuses the winner of cheating and the controller tests the winner if and only if the winner is accused of cheating. Whistle-blowing reduces the frequencies of cheating, is less costly in terms of test frequencies, and leads to a strict Pareto-improvement if punishments for cheating are sufficiently large.Principal-two-Agents; Inspection Games; Asymmetric Information; Signalling

Bespoke controllers and their impact on game feel

This project explores the role and effect of bespoke game controllers on game feel and accessibility. The project aims to develop a range of custom controllers and associated games, designed to tightly couple the user interaction with the game execution. Player analytics will be collected to quantify, explore and improve the user experience.Game feel encompasses a wide range of definitions including intuitive controls, physical interaction with virtual objects, and the appeal of playing. Game feel is subjective and therefore challenging to quantify, but something every player instinctively recognises. There is a growing niche of games utilising bespoke hardware to deliver a unique player experience, such as games played with Unicorn horns or by shouting, rather than the traditional controller. The project seeks to push the boundaries of games and explore how game design, user experience and accessibility are affected when the limitation of traditional input systems is removed. The project has developed four bespoke controllers, utilising creative technologies and physical sensors. The controllers are based on inputs using force sensitive sensors, flex sensors, distance sensor and orientation sensors. Prototype games have been developed for each controller designed to exploit the controllers unique form of user interaction. The next steps are to evaluate the player experience and explore how the various controllers are utilised using a data-driven approach.The project proposes that the bespoke controller could widen engagement and improve the user experience by delivering a more intuitive interface and improving game feel. The project will provide insights and design guidelines for both of the development of the custom game controllers and how they can be linked to certain game mechanics in the associated games

Recall and recognition of in-game advertising : the role of game control

Digital gaming has become one of the largest entertainment sectors worldwide, increasingly turning the medium into a promising vehicle for advertisers. As a result, the inclusion of advertising messages in digital games or in-game advertising (IGA) is expected to grow steadily over the course of the following years. However, much work is still needed to maximize the effectiveness of IGA. The aim of the study was to contribute to IGA effectiveness research by analyzing the impact of two factors on the processing of IGA in terms of brand awareness. The primary objective was to investigate the effect of a person’s sense of involvement related to the control and movement mechanisms in a game (i.e. kinesthetic involvement). A within-subjects experiment was conducted in which control over a racing game was varied by manipulating game controller type, resulting in two experimental conditions (symbolic versus mimetic controller). Results show that the variation in game controller has a significant effect on the recall and recognition of the brands integrated into the game, and that this effect can be partially brought back to players’ perceived control over the game: when a game is easier to control, the control mechanisms require less conscious attention, freeing attentional resources that can be subsequently spent on other elements of the game such as IGA. A second factor that was taken into account in the study was brand prominence. The influence of both the size and spatial position of in-game advertisements was examined. Findings demonstrate that there are significant changes in effectiveness between different types of placements. Spatial position seems to be the most important placement characteristic, with central brand placements obtaining the highest recall and recognition scores. The effect of ad size is much smaller, with the effectiveness of the large placements not differing significantly from the effectiveness of their smaller counterparts

ICARUS: a game/performance for drum-kit and live electronics.

ICARUS is a game/performance for drum-kit and live electronics. The work explores improvised musical structures within an game setting, where the player navigates between five musical chapters. Each of these levels defines a particular set of musical interactions, sonorities, and performance possibilities through distinct mappings and level design. The performer is free to improvise, fail, explore, and through trial and error understand what the game rules are and complete each chapter. This results into a dynamic audio-visual performance, where while the rules are fixed, each level can be completed in multitude of ways.The game is designed specifically for the augmented drum-kit and the instrument's affordances; performance minutiae, digital electronics and musical parameters are analyzed and used as control input to the game. As the musical instrument offers a much wider range of expressive possibilities compared to a conventional game controller, the result is a musically expressive game play performance where the game acts as the mediator to the improvised drum-kit performance, while the musical output becomes the live soundtrack of the game.<br/

A robust momentum management and attitude control system for the space station

A game theoretic controller is synthesized for momentum management and attitude control of the Space Station in the presence of uncertainties in the moments of inertia. Full state information is assumed since attitude rates are assumed to be very assurately measured. By an input-output decomposition of the uncertainty in the system matrices, the parameter uncertainties in the dynamic system are represented as an unknown gain associated with an internal feedback loop (IFL). The input and output matrices associated with the IFL form directions through which the uncertain parameters affect system response. If the quadratic form of the IFL output augments the cost criterion, then enhanced parameter robustness is anticipated. By considering the input and the input disturbance from the IFL as two noncooperative players, a linear-quadratic differential game is constructed. The solution in the form of a linear controller is used for synthesis. Inclusion of the external disturbance torques results in a dynamic feedback controller which consists of conventional PID (proportional integral derivative) control and cyclic disturbance rejection filters. It is shown that the game theoretic design allows large variations in the inertias in directions of importance
