User Interfaces and Methods for Operating a Mobile Computing Device for Location-Based Transactions

A portable device, having thereon a processor for executing instructions comprising program code to at least:

• detect a gesture performed using the portable device, wherein detecting the gesture comprises detecting a yaw component of the gesture;
• identify a first polygon, wherein the first polygon is defined, at least in part, based on a current geographic location of the portable device, a current compass orientation of the portable device, a distance, and the yaw component;
• identify a second polygon, wherein the second polygon is defined, at least in part, based on the current geographic location of the portable device adjusted for a pre-determined geographical offset, the current compass orientation of the portable device, the distance, and the yaw component;
• and
• in response to the gesture, initiate a search, at least in part, by providing a search query comprising a search string, a search target geographic location, and a geographical search area about the search target geographic location, wherein geographical search area is based on the first polygon and the second polygon.

A method comprising:

• determining a geographic location of a mobile computing device;
• determining a geographical offset location:
• detecting a mobile computing device orientation of the mobile computing device relative to a point-of-transaction location;
• detecting a gesture made with the mobile computing device;
• communicating with a remote database to identify possible transactions in the remote database that are associated with the point-of-transaction location, wherein associations of the possible transactions with the point-of-transaction location are based on a geographical search area for the mobile computing device and/or the geographical offset location, wherein the geographical search area is based, at least in part, on the gesture, the geographic location of the mobile computing device, and a search angle determined from a yaw component of the gesture;
• retrieving retrieved transaction details of the possible transactions independent of an orientation of the mobile computing device;
• filtering the retrieved transaction details based on the orientation of the mobile computing device to determine a filtered set of transactions that excludes those retrieved transaction details that are between the geographic location of the mobile computing device and the geographical offset location;
• presenting at least one presented transaction of the filtered set of transactions on a display;
• and
• receiving input related to the at least one presented transaction.
