TLDR
In this article, the authors present a presentation supporting device having excellent operability and adaptability to oral presentations in a computer multimedia environment, where the first and second accelerometers detect first-and second acceleration of gravity resulting from inclinations in firstand second sensitivity axis directions perpendicular to each other.Abstract:
A presentation supporting device having excellent operability and adaptability to oral presentations in a computer multimedia environment. First and second accelerometers detect first and second acceleration of gravity resulting from inclinations in first and second sensitivity axis directions perpendicular to each other to output first and second acceleration signals, and first and second signal processors process the input first and second acceleration signals to output cursor moving control signals for controlling moving speeds and moving directions in the first and second coordinate axis directions of a cursor on a computer display screen in response to voltage values and polarities of the first and second acceleration signals.read more

A batch-fabricated silicon accelerometer
L.M. Roylance,J.B. Angell +1 more
TL;DR: In this paper, an extremely small batch-fabricatable accelerometer has been developed using silicon IC technology, which is capable of measuring accelerations from 0.001 to 50 g over a 100Hz bandwidth, while readily implemented geometry changes allow these performance characteristics to be varied over a wide range to meet the needs of differing applications.
