Effectiveness vs efficiency 2x2
In recent years HCI researchers have made significant ...
A 2x2 between subjects design was used: gender pairing (male/male vs. female/female), and pre-task interaction (interaction vs. no interaction). All participants used the AOL IM System to do the task. The pairs were strangers and the gender of the partners was revealed by the experimenter immediately before pairs performed their task. Participants

Consider a production function consisting of both Capital and Labor, Q = F(K,L) = K x L. When one unit of each input is used Q = 1. Doubling both inputs increases outputs to 2x2 = 4. This firm has increasing returns to scale. A firm with the production function Q = F(K,L) = (KL).5 has constant returns to scale.

Overall VE effectiveness may be reduced if users spend most of their time and cognitive capacity learning how to interact and adapting to interacting with a purely virtual environment. We investigated how handling real objects and how self-avatar visual fidelity affects performance on a spatial cognitive task in an immersive VE.
