This work presents a novel user interface for navigation in virtual environments and remote control of devices. The proposed system is head-mounted, allowing for the control of up to six degrees of freedom while leaving the user with free hands. The device is composed of six linear accelerometers arranged on a couple of glasses and a specific embedded controller that allows for the measuring of glass acceleration information. This is then translated in motion control information for navigation in virtual environments and/or as other devices input. The specific algorithms to integrate the motion acceleration cues sensed from the glasses while filtering the drifting errors and effect related to head rotations are presented herein.

Abstract
This work presents a novel user interface for navigation in virtual environments and remote control of devices. The proposed system is head-mounted, allowing for the control of up to six degrees of freedom while leaving the user with free hands. The device is composed of six linear accelerometers arranged on a couple of glasses and a specific embedded controller that allows for the measuring of glass acceleration information. This is then translated in motion control information for navigation in virtual environments and/or as other devices input. The specific algorithms to integrate the motion acceleration cues sensed from the glasses while filtering the drifting errors and effect related to head rotations are presented herein.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
