Portable viewer with magnifying glass-like user interface

We propose a portable viewer with a user interface in which the contents of the screen, displayed as output, change based on the movements of the viewer itself, as which is used input. The user interface requires no special input devices such as a keyboard or mouse. First, we begin by analyzing the portable viewer´s movements and discussing the detection sensor. Next, we detail the output display control parameters based on movement parameters detected as input information. Finally, we give the results of an experiment with an embedded microcomputer for consumer use and a small sensor that demonstrates the feasibility of our proposal.
