Towards an objective corroborative measure of presence : postural responses to moving video

The current pace of technological development in networks, computing power and displays, as well as improvements in human-system interfaces, enable the creation of services that are capable to elicit a sense of presence in the user. The concept of presence has relevance and implications for the design and evaluation of a broad range of interactive and non-interactive media, and applications in areas such as training and education, telecommunications, medicine, and entertainment. Scientific research into presence is still at a relatively early stage of development. From the early 1990s onwards, the subjective sensation of ‘being there’ in a remote or mediated environment has been studied in relation to various media, most notably virtual environments (VEs). Although substantial progress has been made in presence research, there still exists a clear need for a reliable, robust and valid methodology for measuring presence
