The first diagram represents the relationship between a wearable computer and the human. In this case, the computing is not the primary task as the human can be doing other activities while on the computer, simultaneously at the same time.
The second diagram represents the traditional relationship between a regular, nonwearable computer with a human. This computing is based on the notion that computing is the primary task. The human provides the input and recieves the output while on the computer.
The wearable computer (WearComp) is more than just eyeglasses or a wrist-watch, it is designed to intertwine with its user. It replaces regular computers, with keyboards and mousepads. Also laptops, blackberries, PDAs, and ipod touch since WearComps are a combination of these devices. Users don't have to be sitting down at a desk, like I was now, to be on the computer, or be holding a handheld gadget while walking and checking emails. WearComps go a step further than PDAs and Blackberries in that they incooperate the entire body and movements for accessing the internet. The user actually wears the major components of the computer on them, appearing as if they're walking computers.
