  2. Overview • Project Goals • Challenges • Main Steps • Technologies • Schedule

  3. Project Goals • Sightless navigation by sensory substitution • Development of an application that allows a person to navigate, relying primarily on the sense of hearing • Development of spatial auditory environment • Providing a flexible testing environment for future research

  4. Main challenges • 3D sound generation • Choosing / generating sound samples that on one hand will reveal as much information as possible about the visual objects and on the other hand will be intuitive (easily interpreted). • Image analysis • Applying a reliable object tracking mechanism

  5. Main steps • Shapes detection • Objects tracking • Sounds creation (according to a 3D image) • Human subject research

  6. Technologies • Image processing • OpenCV • 3D sound generation and processing • Binaural spatialization using HRTF datasets • OpenAL (Creative Labs / Rapture3D) • JavaSound3D • DirectSound3D

  7. Project schedule (expected) • Summer 2010 – Theoretic research • Learning and testing 3D sound & image technologies • October – November • Choosing technologies • System architecture • Application Requirements Document draft • December – January 2011 • Final version of ARD • Working on prototype

  8. Project schedule (cont.) • February – March • Final prototype • Application Design Document draft • Application development • April - May • Final version of ADD • Application testing and experiments conduction • June • Preparation to the Projects day
