Conflict and Interference Resolution for Physical Annotation Systems

Abstract

Physical Annotation (PA) systems have been widely used in recent years. They help users to annotate the physical entities around them with digital data for different purposes such as education, tourism or personal memories. One of the main problems with the widespread use of PAs is conflict and interference between different annotations for the same entity. Therefore, this paper studies conflict and interference issues in PA systems. The paper first provides a formal definition of PA conflict and interference, and then explains the causes and sources. Based on this, we propose detection techniques and provide policies to resolve conflict and interference in PAs. Finally, we present an implementation of the techniques.
