We describe the design and trial of a remotely conducted surgical master class, using a haptic virtual environment as an integral part of the learning process. In the trial, we linked a haptic virtual environment in Canberra, Australia with a second installation at Stanford University, California. We were testing several haptic components of the system, and… (More)
A worker performing a physical task may need to ask for advice and guidance from an expert. This can be a problem if the expert is in some distant location. We describe a system which allows the expert to see the workplace from the worker's point of view, and to draw annotations directly into that workplace using a picoprojector. Since the system can be… (More)
This paper presents a system that will support a remote guidance collaboration, in which a local expert guides a remotely located assistant to perform physical, three-dimensional tasks. The system supports this remote guidance by allowing the expert to annotate, point at and draw upon objects in the remote location using a pen and tablet-based interface to… (More)
We describe a (face-to-face) collaborative environment that provides a coherent mix of real world video, computer haptics, graphics and audio. This system is a test-bed for investigating new collaborative affordances and behaviours.
This sketch describes a collaborative virtual environment application involving haptic interaction over long Internet distances. We have developed algorithms to accommodate significant latency for certain applications, notably in the medical domain. The results have shown that we can manipulate simulated human body organs, as well as guide each other's… (More)
This paper describes the development of a tele-robotic rock breaker deployed at a mine over 1000kms from the remote operations centre. This distance introduces a number of technical and cognitive challenges to the design of the system, which have been addressed with the development of shared autonomy in the control system and a mixed reality user interface.… (More)
