Humans have the innate ability to easily explore their surroundings. With sensor-rich mobile devices, everyday people can become data contributors by interacting in physical space. PGAP leverages that ability in order to build detailed models of the world. Notably, we use the concept of immersive, interactive gaming to build the data-gathering model. PGAP creates an interactive, physical-space experience that allows expansive data to be collected. This data can then be fed back into the system to create a stronger immersive experience, allowing more data to be collected.
