State driven mobile search

摘要

Methods, apparatuses, and systems are provided to process search queries initiated at a mobile computing device based, at least in part, on a state of the mobile computing device as indicated by one or more of travel speed, travel direction, and geographic location of the mobile computing device.

1. A method, comprising:
obtaining a search query initiated at a handheld mobile device, said search query comprising one or more search terms; obtaining an indication of geographic location of said handheld mobile device, and an inertial state of said handheld mobile device indicated by one or more inertial sensor measurements obtained at said handheld mobile device, wherein the inertial state comprises a speed and a travel direction; processing said search query to obtain one or more search results responsive to said one or more search terms, said one or more search results limited to a geographic scope that has a shape and an orientation based, at least in part, on the speed and the travel direction of said inertial state indicated by said one or more inertial sensor measurements; wherein the geographic scope of the one or more search results is limited to a search region in the travel direction of said inertial state of the handheld mobile device by:
defining a geographic search region based on said inertial state of said handheld mobile device, and identifying said one or more search results from within said geographic search region responsive to said one or more search terms of said search query; andorientating said geographic search region relative to said geographic location by aligning an axis of symmetry of said geographic search region with said travel direction of said handheld mobile device, and offsetting said geographic search region from said geographic location in a direction indicated by said travel direction of said handheld mobile device, wherein an offset is a distance from a centroid of said geographic search region to said geographic location of said handheld mobile device; and continuously updating said geographic search region relative to changes in orientation of said handheld mobile device indicated by said one or more inertial sensor measurements.
