New study finds blind people have the potential to use their 'inner bat' to locate objects
May 21, 2013 12:48 pm | by EurekAlert! | CommentsNew research from the University of Southampton has shown that blind and visually impaired people have the potential to use echolocation, similar to that used by bats and dolphins, to determine the location of an object. The study, which is published in the journal Hearing Research, examined how hearing, and particularly the hearing of echoes, could help blind people with spatial awareness and navigation.
New study recommends using active videogaming ('exergaming') to improve children's health
May 21, 2013 12:45 pm | by EurekAlert! | CommentsLevels of physical inactivity and obesity are very high in children, with fewer than 50% of primary school-aged boys and fewer than 28% of girls meeting the minimum levels of physical activity required to maintain health. Exergaming, using active console video games that track player movement to control the game (e.g., Xbox-Kinect, Wii), has become popular....
