Actors

End-user Description

This use case describes the process of a user’s interest in query of objects (experiences) within a specified range and direction from a user-specified location. Pre-conditions

AR-capable device, GPS or location source, network connectivity. Flow of events

 User turns on the device and identifies content of interest (profile info: qualifications, subscriber status, interest/topic). User moves through the environment either based on actual location (from personal GPS) or proxy location. Breadcrumbs/handle/label are shown in the field of view for selection by user. User identifies area/point of interest (bearing, azimuth, distance) and topic/content of interest. “What is that?” User receives objects/experiences as specified within range and content definitions. 

Post-conditions

Experiences are interacted with by user software. Remarks

We will designate this use case is the closest (in terms of user input and responses) to the “traditional catalog use case” with which people are likely to be familiar. Instead of typing in the query parameters and pop-up menus, the sensor is directed by the user.
