By studying how rats navigate their environments, Queensland University of Technology professor Michael Milford was inspired to use cameras and algorithms to create more accurate GPS technology. Sequence Simultaneous Localization and Mapping, or SeqSLAM, mathematically calculates location using visual-based technologies, which could help secure location data quickly in places with limited satellite reception. "For example, if I am in a kitchen in an office block, the algorithm makes the assumption I'm in the office block, looks around and identifies signs that match a kitchen. Then if I stepped out into the corridor, it would test to see if the corridor matches the corridor in the existing data of the office block layout," Milford said.
