Systems such as Google Street View and Bing Maps Streetside enable users to virtually visit cities by navigating between immersive 360° panoramas, or bubbles. The discrete moves from bubble to bubble enabled in these systems do not provide a good visual sense of a larger aggregate such as a whole city block. Multi-perspective “strip” panoramas can provide a visual summary of a city street but lack the full realism of immersive panoramas.

The movie below provides an overview of the system:

In a paper at SIGGRAPH Microsoft presented Street Slide, which combines the best aspects of the immersive nature of bubbles with the overview provided by multiperspective strip panoramas. They demonstrated a seamless transition between bubbles and multi-perspective panoramas presenting a dynamic construction of the panoramas which overcomes many of the limitations of previous systems.

As the user slides sideways, the multi-perspective panorama is constructed and rendered dynamically to simulate either a perspective or hyper-perspective view. This provides a strong sense of parallax, which adds to the immersion.
