Abstract
X-direction double integratorintegrates twice an acceleration that is detected by x-direction acceleration sensor, estimating a traveled distance in an x direction. Y-direction double integratorintegrates twice an acceleration that is detected by y-direction acceleration sensor, estimating a traveled distance in a y direction. Detection boundary storage unitstores a monitoring area. Detection boundary comparatordetermines whether the projector device is positioned outside of the monitoring area or not based on the traveled distance in the x direction which is estimated by x-direction double integrator, the traveled distance in the y direction which is estimated by y-direction double integrator, and the monitoring area stored in detection boundary storage unit
