A UI widget is also available, making it simple for developers to embed a full navigation session within their application.

Indoor and Outdoor Location with Sensor Fusion

Mockup of phone displaying routing using Look4 APIThe cornerstone of Look4’s location technology is “Sensor Fusion” which combines data from multiple sensors, including various wireless networks (cellular, WiFi, and Bluetooth), acceleration/orientation, and air pressure. These are processed simultaneously using on-device and cloud-based stores of reference information to determine a device’s location within a few meters, both horizontally and vertically. These sensor datum are processed in conjunction with GPS data, filling in the gaps when GPS is partially obstructed or unavailable.

The result is that with Look4’s patented sensor fusion technology, accurate location fixes can b obtained with or without a GPS signal, offering both indoor and outdoor location fixes. All with the power consumption 20% of a typical GPS based system. In addition, the Look4 location vector tells your application the devices current bearing, velocity, altitude, ambient temperature and current lat/long.
