Technologies and considerations for developing internet and multiplayer computer games: a tutorial (extended abstract)

Games are universal and probably as old as humankind. Today the development of computer technology, especially the development of fast networks and the Internet, brings games a faster growth than ever before. Game design and development is now a fast-growing entertainment field, with a lot to offer professionally and creatively. In fact, from IT professional’s point of view, creating computer games provides us with all the usual technical challenges associated with software development, such as requirement analysis, architectural design, rapid prototyping, HCI, parallel and distributed processing, code reuse, programming, performance evaluation, testing and maintenance. It also provides challenges on other exciting aspects, such as storyboarding, screenplays, illustration, animation, sound effects, music, and social impact. By developing a computer game from start to finish, one would be able to acquire multi-disciplinary knowledge to become an IT professional for the modern era.

Reducing the risk of abandonment of assistive technologies for people with autism

This paper reports on an investigation that found that conventional techniques for including users in technology design are likely to fail if the user has autism. The heterogeneity of autistic symptomatology across cognitive, social, behavioural and communication domains suggests a 'single user' environment, while rendering typical design interaction techniques meaningless, making the need for assistive technologies great, and the risk of abandonment high. This complex problem of urgency and constraint was addressed through a Delphi study with a panel of psychologists critiquing design activities for people with autism. The major finding is that while each of the activities may work if modified, all require that the designer is well acquainted with autism in general and has a close working relationship based on trust with the individual user. If these requirements are met, there is no reason that the abandonment rate cannot be reduced.

3D haptic needle insertion simulator utilising an agent based spherical voxel model

This paper describes a technique for the real-time modeling of deformable tissue. Specifically geared towards needle insertion simulation, the low computational requirements of the model enable highly accurate haptic feedback to a user without introducing noticeable time delay or buzzing generally associated with haptic surgery simulation. Using a spherical voxel array combined with aspects of computational geometry and agent communication and interaction principals, the model is capable of providing haptic update rates of over 1000Hz with real-time visual feedback. Iterating through over 1000 voxels per millisecond to determine collision and haptic response while making use of Vieta’s Theorem for extraneous force culling.

Haptic control methodologies for telerobotic stair traversal

Teleoperated mobile robots provide the ability for a human operator to safely explore and evaluate hazardous environments. This ability represents an important progression towards the preservation of human safety in the inevitable response to situations such as terrorist activities and urban search and rescue. The benefits of removing physical human presence from such environments are obvious, however challenges inhibiting task performance when remotely operating a mobile robotic system need to be addressed. The removal of physical human presence from the target environment introduces telepresence as a vital consideration in achieving the desired objective. Introducing haptic human-robotic interaction represents one approach towards improving operator performance in such a scenario. Teleoperative stair traversal proves to be a challenging task when undertaking threat response in an urban environment. This article investigates the teleoperation of an articulated track mobile robot designed for traversing stairs in a threat response scenario. Utilising a haptic medium for bilateral human-robotic interaction, the haptic cone methodology is introduced with the aim of providing the operator with a vision-independent, intuitive indication of the current commanded robot velocity. The haptic cone methodology operates synergistically with the introduced fuzzy-haptic augmentation for improving teleoperator performance in the stair traversal scenario.

Extending haptic device capability for 3D virtual grasping

This paper presents an investigation into the workspace constraints observed through the use of multiple single point haptic interfaces, which lead to the design of a novel grasping device that improves upon current commercial haptic interfaces. The presented device is desktop based, and has been designed to maximise the haptic workspace while offering the ability to grasp and manipulate virtual objects, which is a function that current commercial interfaces are limited in providing. The performance of the commercial haptic interface in producing sustained effective operation and increased workspace with the attached haptic gripper is evaluated, and the improvement of both has been determined.

Conceptualising the effect of self-service technologies on established brands

Self-service technologies (SSTs), such as machine assisted and electronic services are prevalent. Many established brands in industries such as banking, retailing, and hospitality have adopted SSTs to complement or replace existing channels of service delivery, e.g., face-to-face service. However, the influence of SSTs on established brands has not been examined previously. In the light of this, a conceptual model is proposed that incorporates SST-related variables and their influence on brand satisfaction, brand associations, brand attitudes, and brand loyalty, along with customers' future likelihood to reuse the SST. Arguably, these outcomes affect brand equity and the long-term survival of SSTs.

Consumer dissatisfaction with self-service technologies : an empirical exploration of its antecedents

Self-service technologies (SSTs) are commonplace for consumers' use, which is reflected in the growing body of literature that pertains to SSTs. The bulk of this literature has focussed on the adoption of SSTs, while relatively little attention has been given to consumers' consumption and evaluation of SSTs. Arguably, this is an area worthy of exploration in the light of frequent reports of consumers' dissatisfaction with SSTs. Therefore, this paper examines the antecedents of consumers' overall dissatisfaction with an SST encounter, and finds that consumers' dissatisfaction with the attributes of the SST and consumers' perceptions of causal controllability explain 50 per cent of the variance in consumers' overall dissatisfaction with the SST Insights into removing the causes of SST dissatisfaction are offered to managers, which are, arguably, important for consumer retention.

Would Kitty Genovese have been murdered in Second Life? Researching the "bystander effect" using online technologies

The increasing use of online technologies, including ‘virtual worlds’ such as Second Life, provides sociology with a transformed context within which to ply creative research approaches to ongoing social issues, such as the ‘bystander effect’. While the ‘bystander effect’ was coined following a real-life incident, the concept has been researched primarily through laboratory-based experiments. The relationship between ‘virtual’ and ‘real’ world environments and human behaviours are, however, unclear and warrant careful attention and research.

In this paper we outline existing literature on the applicability of computer-simulated activity to real world contexts. We consider the potential of Second Life as a research environment in which ‘virtual’ and ‘real’ human responses are potentially more blurred than in real-life or a laboratory setting. We describe preliminary research in which unsolicited Second Life participants faced a situation in which they could have intervened. Our findings suggest the existence of a common perception that formal regulators were close at hand, and that this contributed to the hesitation of some people to personally intervene in the fraught situation. In addition to providing another angle on the ‘bystander effect’, this research contributes to our understanding of how new technologies might enable us to conduct social research in creative ways.

Intuitive haptic control surface for mobile robot motion control

Haptic human-machine interfaces and similar techniques to enhancing human-robotic interaction offer significant potential over conventional approaches. This work considers achieving intuitive motion control of a tracked mobile robotic platform utilising a 3D virtual haptic cone. The 3D haptic cone extends upon existing approaches by introducing of a third dimension to the haptic control surface. It is suggested that this approach improves upon existing methods by providing the human operator with an intuitive method for issuing vehicle motion commands whilst still facilitating simultaneous real-time haptic augmentation regarding the task at hand. The presented approach is considered in the context of mobile robotic teleoperation however offers potential across many applications. Using the 2D haptic control surface as a benchmark, preliminary evaluation of the 3D haptic cone approach demonstrates a significant improvement in the ability to command the robot to cease motion.
