To effectively design computer simulations of shared environments, an understanding is needed of the basic informational requirements and underlying movement patterns generated by two people collaborating in these environments. Results from this study indicate that when passing objects in a natural environment, the fundamental movement patterns seen during simple grasping tasks are altered to accommodate the collaborative nature and social constraints of the task. When giving objects, although subjects reach further they reach more quickly than when the objects are taken. This result may indicate a social consideration taken by the passer to move quickly and efficiently over a long distance to transfer the object to the receiver. Thus, the receiver does not have to travel as far or as fast to receive the given object. However, when objects are taken, passers move more slowly and lift the objects higher. This result may indicate that the passer times their movement so that they are not waiting at the end of their movement for the receiver to reach the target. Thus, although the result of the task is the same (the receiver obtains the object), the underlying movement patterns differ with the goal and social constraints of the movement. These results may be used to develop predictive algorithms when designing virtual and augmented environments. Future experiments will concentrate on the nature of visual and haptic information required for both the passer and receiver to effectively perform a passing task in an augmented environment. |
