3D virtual haptic cone for intuitive vehicle motion control

Haptic human-machine interfaces and interaction techniques have been shown to offer advantages over conventional approaches. This work introduces the 3D virtual haptic cone with the aim of improving human remote control of a vehicle's motion. The 3D cone introduces a third dimension to the haptic control surface over existing approaches. This approach improves upon existing methods by providing the human operator with an intuitive method for issuing vehicle motion commands whilst simultaneously receiving real-time haptic information from the remote system. The presented approach offers potential across many applications, and as a case study, this work considers the approach in the context of mobile robot motion control. The performance of the approach in providing the operator with improved motion controllability is evaluated and the performance improvement determined.

Exploiting ungrounded tactile haptic displays for mobile robotic teleoperation

Teleoperated mobile robotics offer potential use in a variety of different real-world applications including hazardous materials handling, urban search and rescue and explosive ordnance handling and disposal. Recent research discusses the use of Haptic technology in increasing task immersion and teleoperator performance. This work investigates the utility of low-cost, ungrounded tactile haptic interfaces in mobile robotic teleoperation. In order to achieve the desired implementation using only tactile sensation presents distinct challenges. Innovative haptic control methodologies providing the teleoperator with intuitive motion control and task-relevant haptic augmentation are presented within this paper.

Wikis, blogs and podcasts - using Web2 technologies in teacher education

This paper presents a reflection on the infusion of Web2 technologies into a teacher education program. It explores issues surrounding the use of a range of Web2 technologies including wikis, blogs and podcasts. Web2 technologies are currently being taken up at amazing speed. This paper draws on the experience of using these new technologies in two units of a pre-service education course. As part of their assignment requirements pre-service education students were immersed in these new technologies as they grappled with issues to do with learning how to use these technologies as well as reflecting on how and why, or why not, they might they might use them in primary schools including the potential for democratic collaborative communities of learners. The opportunities the Web2 technologies afford educators as well as the consequences of such educational use of social technologies will be considered.

3D virtual haptic cone for intuitive vehicle motion control

Haptic technology provides the ability for a system to recreate the sense of touch to a human operator, and as such offers wide reaching advantages. The ability to interact with the human's tactual modality introduces haptic human-machine interaction to replace or augment existing mediums such as visual and audible information. A distinct advantage of haptic human-machine interaction is the intrinsic bilateral nature, where information can be communicated in both directions simultaneously. This paper investigates the bilateral nature of the haptic interface in controlling the motion of a remote (or virtual) vehicle and presents the ability to provide an additional dimension of haptic information to the user over existing approaches [1-4]. The 3D virtual haptic cone offers the ability to not only provide the user with relevant haptic augmentation pertaining to the task at hand, as do existing approaches, however, to also simultaneously provide an intuitive indication of the current velocities being commanded.

The use of Web 2.0 Technologies to promote higher order thinking skills

During 2007 several independent Victorian secondary schools participated in a study exploring the ways in which the use of learning technologies can support the development of higher order thinking skills for students. This paper focuses on the use of Information and Communications Technologies (ICT) including Web 2.0 technologies for promoting effective teaching and learning in science. A case study methodology was used to describe how individual teachers used ICT and Web 2.0 in their settings. Data included interviews (focus group and individual), questionnaires, monitoring of teacher and student use of smart tools, analysis of curriculum documents and delivery methods and of student work samples. The evaluation used an interpretive methodology to investigate five research areas: Higher-order thinking, Metacognitive awareness, Team work/collaboration, Affect towards school/learning and Ownership of learning. Three cases are reported on in this paper. Each describes how student engagement and learning increased and how teachers’ attitudes and skills developed. Examples of student and teacher blogs are provided to illustrate how such technologies encourage students and teachers to look beyond text science.

Assisting independence with "the latest and greatest" of technologies

A case study of a long term wheelchair user: This presentation will highlight the difficulties associated with matching client's environmental access, seating and mobility needs using multi-functional systems, which also happen to be the "latest and greatest" technologies. The paper addresses the issues experienced by these clinicians when prescribing systems with minimal trial history (due to their newness) and the compatibility issues encountered by the supplier when matching the new with the old of the current powered wheelchair for a particularly motivated wheelchair user.

Constructing emergent literacy : negotiating literacy technologies in preschool-school transition

Examines conflicting views about early literacy in homes, Preschools and schools as interactive technologies challenge traditional print-based literacies. The research found that significant differences between children's multimodal literacies and versions of emergent policies, may threaten successful literacy acquisition.

Supporting gen Y's engagement, enrichment and entertainment in interactive technologies

This research explored the potential for expansion of the current function, and usage of Interactive Television. The interviews and group discussions assisted in the determination of the theoretical framework for "Interactive Digital Vision", including its inspiration from current technologies to provide an engaging, enriching and intertaining user experience.
