Virtual Reality based Telerobotics Framework with Depth Cameras
This work describes a virtual reality (VR) based robot teleoperation framework which relies on scene visualization from depth cameras and implements human-robot and human-scene interaction gestures. We suggest that mounting a camera on a slave robot's end-effector (an in-hand camera) allows the operator to achieve better visualization of the remote scene and improve task performance. We compared experimentally the operator's ability to understand the remote environment in different visualization modes: single external static camera, in-hand camera, in-hand and external static camera, in-hand camera with OctoMap occupancy mapping. The latter option provided the operator with a better understanding of the remote environment whilst requiring relatively small communication bandwidth. Consequently, we propose suitable grasping methods compatible with the VR based teleoperation with the in-hand camera. Video demonstration: https://youtu.be/3vZaEykMS_E
Bell Inequality and Many-Worlds Interpretation
It is argued that the lesson we should learn from Bell's inequalities is not
that quantum mechanics requires some kind of action at a distance, but that it
leads us to believe in parallel worlds.Comment: To be published in "Quantum Nonlocality and Reality", ed. by Mary

Supporting memory and identity in older people: findings from a ‘Sandpit’ process
Identity in old age is challenged by physical changes, evolving roles within the family, and life transitions such as retirement. Supporting identity is therefore important in later life, and might be assisted by media technologies which allow people to reflect on their lives, record their personal histories and share these with family, friends and caregivers. This possibility was explored in two creative ‘Sandpits’ with older people as part of the SUS-IT project, funded by the New Dynamics of Ageing programme in the UK. Discussions were held with PC and non-PC user groups of retirement age to understand memory and identity practices and elicit reactions to three novel product concepts. These included a Reminiscing Radio for life review, a Story Lamp for associating spoken stories with photographs and memorabilia, and a pair of virtual reality Travel Glasses for transporting you back to a special place in the past. The main findings of these discussions will be presented, along with concepts generated by the participants in a re-design exercise. This paper will also show how the sandpits enabled older people to be involved in the design process by allowing them to shape early design concepts through exploring their own ideas and motivations
MiRTLE (Mixed-Reality Teaching and Learning Environment): from prototype to production and implementation
This position paper focuses on our efforts to implement and evaluate a Mixed Reality Teaching and Learning Environment (MiRTLE) in higher education institutions and other organisations, our current technical research to streamline and improve the utility of the system, and potential pedagogical developments for MiRTLE in the future
