What is Soundscape?
Microsoft Soundscape is a research project that explores the use of innovative audio-based technology to enable people, particularly those with blindness or low vision, to build a richer awareness of their surroundings, thus becoming more confident and empowered to get around. Unlike step-by-step navigation apps, Soundscape uses 3D audio cues to enrich ambient awareness and provide a new way to relate to the environment. It allows you to build a mental map and make personal route choices while being more comfortable within unfamiliar spaces.

How does Soundscape work?
Soundscape provides information about your surroundings with synthesized binaural audio, creating the effect of 3D sound. It can run in the background in conjunction with navigation or other applications to provide you with additional context about the environment. Your phone, in hand or in pocket, tracks movement using location and activity sensors, and lets you move toward a self-set audio beacon. Soundscape runs on iPhone 5S or later and is compatible with most wired or Bluetooth stereo headsets.
