Abstract
Introduction. Homonymous Hemianopia is characterized by the loss of half of your visual field in both of your eyes due to a brain injury. To find out whether people with newly acquired hemianopia show different scanning behaviour in comparison to people who have had hemianopia for a long time we conducted an experiment in which participants had to cross a road in virtual reality. We do this by comparing people with people with hemianopia, people with simulated hemianopia and people with unimpaired vision. Method. 18 subjects with hemianopia, 18 with simulated hemianopia and 18 without any visual impairment had to cross a virtual road with cars approaching from both sides. We analysed their performance and their scanning behaviour by studying the exploration of the participants through saccades and head movements per minute, the amount of time they looked towards cars and their safety margin. Results. The three groups did not differ significantly on the variables saccades and head movements per minute, the amount of time looked towards cars and safety margin. Conclusion. As there are no significant differences found between the three groups this suggests that people with newly acquired hemianopia cross the road just as safe as people who have had hemianopia for a long time and show similar scanning behaviour. Further research is needed to find out if similar scanning behaviours are present in other circumstances and environments.
