4046.4 Risk perception and linkage model of decision making, Shoji Tsuchida, Kansai
University, Japan
Linkage Model (LM; Tsuchida, 1994, 2002) is an attitude structure model which assumes that the
concept of acceptance (positive evaluation/valence) or/and the concept of rejection (negative
evaluation/valence) would activate on decision making processes. When an attitude object has the
direct linkage with the concept of acceptance/rejection, it would have associations in adjective and
decisions would make through automatic processes, while in case of the indirect linkage, it would
have associations in noun and decisions would make through deliberative processes. The survey
data on chemical risks of 1,236 samples from Tokyo Metropolitan Residents supported the
hypotheses of LM.

Collaboration in a virtual environment presents many challenges for interface design. It is often
important to support the users' ability to navigate to a desired location while maintaining spatial
awareness of their surroundings. Displays that supply the awareness information can exihit
different degrees of intrusiveness to the user's task at hand. Using a collaborative navigation task,
this work experimentally tested three awareness aids with varied levels of intrusiveness:
Automatic View Switch, Overlay Labels and Tethered Camera View. The results indicated that,
with careful design, intrusive awareness aids can enhance collaborative navigation performance
without negatively impacting users' spatial environment learning.

Understanding the effects of eye gaze on speech and turn taking is crucial for the design of
Collaborative Virtual Environments. We manipulated the gaze synchronization and the level of
gaze, and found that subjects significantly speak more when gaze behavior was synchronized with
conversational attention. However, covariance analysis showed results were likely due to
differences in gaze level rather than gaze synchronization. The result validated the emotional
function of gaze as a favorable explanation of gaze effect on human interaction in multiparty
conversation.
