In order to fully test how well cyberspace addresses human needs, the subjects must be permitted to install internet telephoning and video conferencing equipment. Cyberspace does offer visual and auditory contact with people. In fact, such communication will be an important feature of the future internet. One important feature of the study could be an analysis of how and why some people seek out visual and auditory communication, while others do not. We should recognize the fact that no matter how complete we attempt to make the immersion, it by necessity can only be partial.
People have physical bodies.
Even though restricted to an apartment, they are still living within a physical space filled with physical sensations. They may hear sounds or voices outside the apartment. They may have a chance encounter with a delivery man or research assistant. The immersion is a see-through, fragile bubble that can pop at any moment. A week is probably not long enough.
