I am in here: Implicit assumptions about proximate selection of nearby places

A mobile application whose functionality is somehow based on the ability to connect to locative digital environments, needs to be able to bridge between its current location and a digital counterpart of her current place. This is normally envisioned as a simple proximate selection process, where the application searches the surrounding environment and selects, or assists the user in the selection, of the appropriate place. However, with place-based services becoming truly ubiquitous, for any particular location, there will always be multiple potential target places for selection. In this work, we are concerned with these real-word challenges and their implications for wide-scale contextual place selection. The objective is to investigate the main elements that may affect the reliability of a selection process based on the proximity to virtual representations of places. The research design is organized around the type of place environment in regard to place density and the distance between the place discovery query and the ground zero position representing the location of the target place. The results show that, even for small distances, the ability of the system to identify the target place as the most relevant place or even to return the target place as a possible place for selection, can be severely affected, especially in environments with high place density. The key implication is that virtual discovery, by itself, is not a suitable method for place selection, and should be combined with other techniques, such as detection of physical proximity or explicit user indications.
