Alohar can be more precise positioning

In 2006, Google SamLiang began work on geographic location of this large project, and pioneered the use of blue point to indicate to the user the first position.

After 6 years today, in SamLiang's company, AloharMobile, he developed a new blue point: more accurate, more energy saving.He wanted to create a new position tracking technology.

Alohar not only used the general location used in the process of the sensor (such as a GPS receiver or Wi-Fi), has also joined the many other sensors and algorithms, including some of the things Liang is unwilling to divulge.But OK and affirmative is, including the accelerometer and the guide device, and a statistical model to determine whether the user is most likely in position.

Vehicle Double Din DVD Bluetooth applications using such a model: since you are in a car, these applications by default you in the street, even if the GPS does not take you directly positioned in the street, Double Din DVD Bluetooth applications will take you to the nearest road "pull".Alohar do something similar, but it will use more data: for example, if you are at a walking pace in mobile, which you will be positioned on the sidewalk or construction, but not in the middle of the main street.If your mobile phone camera induction to fluorescent light, it will be you is positioned in the interior of a place.If you stop moving, Alohar will turn off the GPS again until you begin to act now, this is its precise positioning while saving a way.

The ultimate goal is to use at any time, can get the accurate position information of data, and does not waste battery.This can lead to lots of cool things.Press conference on March, Liang shows how the application to determine whether users suffered a car accident, and automatically sending emergency information.Alternatively, the user can press the Help button to demand of emergency rescue.According to Liang standard mobile phone GPS cannot accurately enough to help health care professionals or the police found a wounded man, Alohar in precise positioning is much better.

Alohar also for its application of PlaceMe bundled with a rich location database.The application will always keep a record of your position, the establishment of a list of places you have been to, and marked you in every place to stay how long.It is a terrifying thing, you make the trip will be completely recorded, and the information is associated with the mobile phone hardware ID binding, not personally identifiable information, privacy is worrying, once the information is being used by someone else, the user only complain.

Double Din DVD Bluetooth car comments: of course, now PlaceMe is not very perfect, energy-saving is still a problem, but subsequent updates have been made.The ultimate goal of Liang is to promote this precise positioning technology, PlaceMe is just one example.Now has 600 developers to register and try Alohar technology.AloharSDK for free, the majority of development enthusiasts can go to experience.
