The attention-tracking iTagPro smart device (ETD) is a headmounted gadget, designed for measurement of 3D eye and head movements beneath experimental and natural situations. The tracker permits comprehensive measurement of eye movement (three degrees of freedom) and optionally head movement (six levels of freedom). It represents a software for the investigation of sensorimotor behaviour, notably of the vestibular and oculomotor iTagPro support programs in both health and illness. It was initially developed by the German Space Agency (DLR) for use on the International Space Station (ISS) and was uploaded to the station as a part of the joint European / Russian house programme in early 2004. The machine was designed by Prof. Dr. Andrew H. Clarke (Vestibular Lab, iTagPro smart device Charité Berlin) together with the businesses Chronos Vision and Mtronix in Berlin and built-in for house utilisation by the Munich-based mostly firm Kayser-Threde. In the first set of experiments, conducted by Prof. Clarke’s group in cooperation with the Moscow Institute for Biomedical Problems, the eye Tracking Device was used for the measurement of Listing’s aircraft - a coordinate framework, which is used to outline the motion of the eyes in the head.

The scientific aim was to find out how Listing’s plane is altered below numerous gravity circumstances. Particularly the affect of long-duration microgravity on board the ISS and of the next return to Earth’s gravity was examined. The findings contribute to our understanding of neural plasticity in the vestibular and oculomotor systems. These experiments had been commenced in the spring 2004 and continued until late 2008 with a collection of cosmonauts and astronauts, ItagPro who each spent six months on board the ISS. Examination of the orientation of Listing’s aircraft throughout the course of a prolonged house mission is of specific interest, as on Earth the Listing’s aircraft seems to be dependent on enter from the vestibular system i.e. detected by way of the top position with relation to gravity.
