Using online technologies: does culture matter?

There has been an increase in the number of international students studying information technology programmes in Australia. There is little information about how this group uses online technologies. The overall aim of this research was to investigate how students use online technologies and teaching resources. A secondary aim was to determine whether there were any differences between international and local students using the online environment. The study consisted of two parts: an online survey  questionnaire and an analysis of the student’s use of the online environment. The overall results showed very little difference between two cohorts and that these results would be enhanced by further research into educational and cultural backgrounds.

Soft tissue modelling for haptic rendering in virtual environments

This paper focuses on the development of a haptic recording and modelling system. Currently being evaluated for multiple uses in surgery and manufacturing, this recording system evaluates haptic data captured via a robotic ann coupled with real time high-resolution load cell. This data is then analysed and validated against previous samples and a generated model before being logged for playback during simulation and training of a human operator. 3D models of point force interactions are created allowing unique visuals to be presented to a user. Primarily designed for the medical field, recorded results of soft tissue cutting have been presented.

Beyond pretence: new sensibilities for computing and communication technologies in teacher education

Making particular reference to schools’ traditional relationships with CCTS (and the kinds of ‘pretend’ and ‘artificial’ learning/assessment tasks that this relationship has historically produced), this paper details a research and teaching agenda focused on exploring the potential of having students work on tasks with value to local and/or school communities. The paper maps the informing theories and current practices of schools
participating in the ‘knowledge producing schools’ (KPS) agenda. Particular attention is given to the ways in which KPS schools are better positioned to respond to the needs of diverse student/community populations, particularly those students traditionally perceived as ‘at risk’.

Haptic handwriting aid for training and rehabilitation

This paper reports a method of controlling a user's hand through the process of writing. Developed predominantly for enabling users to re-learn the skill of writing after a stroke, the process could also be used for teaching children hand/eye coordination, motor skills, movement and position awareness in writing. Utilising low cost haptic technology and custom control software, the system has the potential to increase writing skills in stroke sufferers in the privacy and comfort of their own home.

Re-envisioning literacy instruction with adolescents: multiliteracies, multimodality and new technologies

Engaging students' lifeworlds and the concerns of their communities in globalised, semiotic and information societies is imperative in New Times. As youth continue to exhibit their proficiency with new literacies emerging from Internet communication technologies (leTs), education-particularly curriculum and instruction-remains largely focused around monomodal, print-only literacy practices, often ignoring students' hybrid multiple voices. This paper reports on two curricular interruptions to the progressive reading and writing workshop that acknowledged adolescents' engagement with digital technologies and their new multimodalliteracy practices in a year eight public classroom within a small urban academy of technology.

Re-envisioning teacher education in the new media age: multiliteracies, multimodality and internet communication technologies

Multiliteracies pedagogy and research (New London Group, 1996) addresses the range of literacies needed by diverse students to effectively negotiate the increasing multimodality of texts, both inside and outside of schools. Yet, few university teachers understand how youth are able to express themselves, their experiences and lives, in new, empowering and perception-shifting ways as designers in the 21st century. Several theorists (Bruce, 2000; Lemke, 1998; Luke, 2000; Bolter, 1998; Glister, 1997) argue literacy education must be reconceptualised to recognize the importance of teaching and supporting multimedia literacy in a world where internet communication technologies (ICTs) incorporate all semiotic resources. Expression through multiple media and more recently hypermedia—is common to youth—but has often been demonized by historically logocentric approaches to teaching and assessment by privileging print, over all other forms of expression (Albright & Walsh, 2003; Lemke, 1998; McCloud, 1993). As digital media becomes more pervasive in a post-typographic world, tertiary education will need to engage with its representational resources for acquiring traditional school literacy and knowledge. This paper reports on initiatives in Multiliteracies instruction for both pre-service and in-service teachers to more adequately attend to the multisemiotic landscapes of students’ changing worlds in New Times (Hall, 1996).

Haptic control of multi-axis robotic systems

Control of tele-operated remote robot’s is nothing new; the public was introduced to this 'new' field in 1986 when the Chernobyl cleanup began. Pictures of weird and wonderful robotic workers pouring concrete or moving rubble flooded the world. Integration of force feedback or 'haptics' to remote robot's is a new development and one that is likely to make a big difference in man-machine interaction. Development of haptic capable tele-operation schema is a challenge. Often platform specific software is developed for one off tasks. This research focussed on the development of an open software platform for haptic control of multiple remote robotic platforms. The software utilises efficient server/client architecture for low data latency, while efficiently performing required kinematic transforms and data manipulation in real time. A description of the algorithm, software interface and hardware is presented in this paper. Preliminary results are encouraging as haptic control has been shown to greatly enhances remote positioning tasks.

Self-service technologies and voice intentions : an empirical investigation

Consumer dissatisfaction with self-service technologies (SSTs) has become prevalent. Although consumers’ voice has been studied in the interpersonal services context, in the context of SSTs it has been subject to very little conceptual or empirical scrutiny. To fill this void, this study tests empirically a model of the antecedents of consumers’ voice intentions in the context of unsatisfactory SST encounters. The findings suggest the need to integrate both “new” and “conventional” complaint behaviour management in the SST setting.

Fuzzy haptic augmentation for telerobotic stair climbing

Teleoperated robotic systems provide a valuable solution for the exploration of hazardous environments. The ability to explore dangerous environments from the safety of a remote location represents an important progression towards the preservation of human safety in the inevitable response to such a threat. While the benefits of removing physical human presence are clear, challenges associated with remote operation of a robotic system need to be addressed. Removing direct human presence from the robot's operating environment introduces telepresence as an important consideration in achieving the desired objective. The introduction of the haptic modality represents one approach towards improving operator performance subject to reduced telepresence. When operating in an urban environment, teleoperative stair climbing is not an uncommon scenario. This work investigates the operation of an articulated track mobile robot designed for ascending stairs under teleoperative control. In order to assist the teleoperator in improved navigational capabilities, a fuzzy expert system is utilised to provide the teleoperator with intelligent haptic augmentation with the aim of improving task performance.
