Performing Presence: From the Live to the Simulated


Uploaded Image

 

from the project website:

 

what creates a sense of presence? - the presence of a live performer ... the presence of the past ... in a memory ... in ruined remains ... the sense of 'being there' in an online community ... in a VR or mixed reality environment ...

The Presence Project is exploring such questions through a documentation of extended processes engaging with presence. Follow these links to explore our work with Lynn Hershman Leeson | Gary Hill | Tony Oursler | Blast Theory | The Builders Association | Paul Sermon

We are also fully documenting a series of performance workshops, led by Tim Etchells | Bella Merlin | Vayu Naidu | Mike Pearson and Mike Brookes | Fiona Templeton | Phillip Zarrilli

In 2007 and 2008 The Presence Project will be conducting two exercises at UCL's CAVE, the first of which is now in development.

RFID Powder Developed By Hitachi

From Pink Tentacle

RFID powder developed by Hitachi

 

Hitachi researchers have developed a new micro-miniaturized radio frequency identification (RFID) chip that is 64 times smaller than their currently available 0.4 x 0.4 mm mu-chips.

At 5 microns thick, the RFID chips can more easily be embedded in sheets of paper, meaning they can be used in paper currency, gift certificates and identification

Virtual reality and biofeedback training for balance

Functional balance and dual-task reaction times in older adults are improved by virtual reality and biofeedback training.

Cyberpsychol Behav. 2007 Feb;10(1):16-23

Authors: Bisson E, Contant B, Sveistrup H, Lajoie Y

Virtual reality (VR) training has been used successfully to rehabilitate functional balance and mobility in both traumatic brain injury (TBI) survivors and elderly subjects. Similarly, computer-based biofeedback (BF) training has resulted in decreased sway during quiet stance and decreased reaction times during a dual-task reaction time paradigm in elderly subjects. The objective of this study was to determine the effect of VR and BF training on balance and reaction time in older adults. Two groups of twelve healthy older adults completed 10-week training programs consisting of two 30-min sessions per week. VR training required that participants lean sideways to juggle a virtual ball. Participants in the BF group viewed a red dot representing their center of gravity on a screen and were required to move the dot to the four corners of the monitor. Measures of functional balance and mobility (Community Balance and Mobility Scale [CB&M]), sway during quiet stance, and reaction time during a dual task paradigm were recorded before training, as well as 1 week and 1 month after the end of the program. Both groups showed significant improvements on the CB&M, as well as decreased reaction times with training. Postural sway during quiet stance did not change significantly.
