Indoor navigation isn't a new concept, but it often requires wireless signals or custom infrastructure, neither of which are entirely reliable. Cambridge Consultants has come up with an as-yet-unnamed technology that purports to solve the issue by utilizing low-power sensors along with a custom formula that don't require an existing framework. According to the Cambridge, UK-based company, all you need are its special Bayesian algorithm and run-of-the-mill smartphone components like accelerometers, gyroscopes and magnetometers to do the job. It has already built a concept chipset (seen above) that could be embedded in existing devices -- you can either map your location directly on it or send that info off to a remote system. The firm says the technology will be useful for firefighters and hospital workers, though we wouldn't complain if it's implemented in trade shows either.
