While the homing pigeon is known for navigating back home over long distances, some other animals, such as the spiny lobster, are able to do the same on a more local level. Research has given some idea that these animals are able to derive positional information from cues that arise from the local anomalies of the Earth's magnetic field. With an accurate compass in every iPhone and Android device, a team of Engineers from the University of Oulu in Finland have created a new breed of indoor positioning technology that does not require WiFi or other beacons, but instead provides a major update to one of Man's oldest navigating technologies.
Using signal processing technology, the university team discovered that steel masses inside buildings twist the Earth's magnetic field such that every spot produces a unique pattern. “Each building, floor and corridor creates a distinct magnetic field disturbance that can be measured to identify a location and generate a map,” explains Dr. Janne Haverinen, the head of the project.
The team realized the practical potential of their findings. To provide a practical solution to be used by smartphone application developers, Dr. Haverinen’s research team has founded IndoorAtlas Ltd to commercialize the innovation. Along with the launch, the company also announces a seed capital investment from the Helsinki-based Vigo accelerator, KoppiCatch.
Valkee, the creator of the bright-light headset used to treat seasonal depression and mood disorders, has published the first results of its clinical and neurobiological research program. The clinical trial, published in Medical Hypothesis, studied therapeutic effects of bright light channeled into the human brain via the ear canal to test the sensitivity of the human brain to light. The trial has been conducted since 2007 and challenges the existing paradigm that light therapy is only effective when transmitted through the eyes.
People with suspicions of Valkee's claimed benefits have long been asking for some proof from a peer reviewed study that acknowledges that the medical concept is sound. Unfortunately this paper will likely do little to remove those suspicions after taking a look at the colorful history of the journal, Medical Hypothesis.
Everyone has an opinion on Valkee, the headset that shoots bright light into the ear canal to treat and prevent Seasonal Affective Disorder (S.A.D.). It's not unreasonable to have some doubts about the device's claims; the theory that the ear canal contains the path to the brain's photosensitive areas is an odd concept to most laymen. And the device, which has small light bulbs inside what looks like MP3 player headphones, does seem strange enough to be touted on a late-night infomercial as a miracle cure for weight loss. But regardless of the misconceptions, this week scientists from the University of Oulu are presenting two peer reviewed clinical trials at the 11th International Forum for Mood and Anxiety Disorders in Budapest with strong results in favor of Valkee's claims.
