Collaborative virtual environments allow younger and older people to interact over long distances and stay in contact with their families and friends. Thus, these virtual environments are considered to be both, a crucial factor for active and healthy ageing and a great chance for future developments that may enhance and alter communication for specific age groups. Yet, to date there is a lack of studies examining differences between younger and older adults with special regards to technology usage factors, presence related factors as well as anxiety measures and psychophysiological arousal during social interactions in a collaborative virtual environment. Consequently, the objective of the current study was to evaluate the above mentioned factors in a group of 20 younger and 20 older adults using a slightly stressful collaborative virtual environment. The corresponding results indicate that virtual environments could indeed be beneficial tools for the communication of both, younger and older adults. Yet, older adults reported significantly lower levels of social presence during the interaction and were less able to handle the system than younger adults. Interestingly however, both groups did not differ in their technology related anxiety or regarding physiological mea-sures of stress during the experience of the virtual environment.
