....Because of Moore s law (which shows no signs of letting up for the next decade) and continuing advances in panel display and projector technology, we may expect hugely powerful ubiquitous computers [7] in many different form factors. Examples include wearable computers (the CMU wearable computers [6]) PDAs, whiteboard sized or even wall sized displays, as well as lightweight, minimally intrusive headmounted displays for virtual and augmented reality. In augmented reality, the user sees computer gener66 February 1997 Vol. 40, No. 2 COMMUNICATIONS OF THE ACM Figure 2. A 3D model appears like ....

....Metronaut is alternatively powered by a mechanical flywheel converting kinetic energy to electrical energy. Keywords: wearable computers, mobile computing, sensing, two way pager, bar code, navigation. 1 Introduction The Metronaut mobile computer exemplifies some of our early vision [1], 2] in being able to sense information and locate position via bar code reader, provide wide range communications via two way pager, supporting applications like navigation, messaging, and scheduling and still consuming less than one watt of power and weighing less than one pound. Metronaut s ....

.... W. For n 1, if this new, faster system is used to define a r , then r r. If n = r [a(1 r) then (1, r ) is the point where the 1.0 contours cross. At this value of r, the CPU frequency is optimal, because any change in n will result in a decrease in W n W. The Navigator 1 wearable computer [4] will serve as an example of how the contour plot can be used. The power of the Navigator 1 was measured to be (5.36 0.15 x CPU frequency) Watts. The minimum operating frequency of the design is 8 MHz and the maximum is 32 MHz. Suppose the current design operates at 8 MHz and a designer would ....

....value of n into the equation forr, one finds that the optimal point is where r = a (a 1) Whether most systems can operate at this point is a question for further investigation. 4. Results The Navigator 1 is a wearable computer intended for a campus tour application and is fully described in [4]. To test the work ratio, the Navigator 1 was modified to run in a continuous loop. The number of loops executed was counted by attaching a logic analyzer to the Navigator 1 s address bus and triggering on an address occurring only once per loop. The Navigator 1 ran until the batteries were fully ....
