Even with Street View, it can be hard to orient yourself in a strange area with a smartphone-based map. The Astonishing Tribe (TAT), an absolutely genius group of UI designers, wants to jazz things up by letting users shift dynamically from a flat object, like a map or a list of contacts, to a 3D one, which can be overlaid with additional information.
Horizon 2D-3D Maps
By allowing the user to seamlessly transition from a two-dimensional display to a three-dimensional one and back, TAT aims to make it easier to comfortably maintain a sense of space and orientation. At the heart of it all lies TAT Cascades, a UI framework for the production of advanced user interfaces.
