The confluence of mobile content sharing and pervasive gaming yields new opportunities for developing novel applications on mobile devices. Yet, studies on users" attitudes and behaviors related to mobile gaming, content sharing and retrieval activities (referred simply as content sharing and gaming) have been lacking. For this reason, the objectives of this paper are three-fold. One, it introduces Indagator, an application which incorporates multiplayer, pervasive gaming elements into mobile content sharing activities. Two, it seeks to uncover the motivations for content sharing within a game-based environment. Three, it aims to identify types of users who are motivated to use Indagator for content sharing. Informed by the uses and gratifications paradigm, a survey was designed and administered to 203 undergraduate and graduate students from two large universities.The findings revealed that perceived gratification factors such as information discovery, entertainment, information quality, socialization, and relationship maintenance, and demographic variables such basic familiarity with features of mobile communication devices, and IT-related backgrounds were significant in predicting intention to use mobile sharing and gaming applications such as Indagator. However, age, gender, and the personal status gratification factor were nonsignificant predictors. This paper concludes by presenting the implications, limitations and future research directions.

“…MobiTOP has been introduced in our previous work [5,6], which describes the client/server architecture of the entire system as well as the concept of multimedia hierarchical annotations. This paper is based on an updated version of the MobiTOP system which consists of a single server and two independent mobile and web clients.…”

The development of numerous information sharing platforms have led to the emergence of multimedia user-generated content. With the prevalence of networking mobile devices and Global Positioning System (GPS) functionality, these contents could also be tagged with their location (geo-tagged) and visualised on a map through a geospatial information system. This in turn raises new challenges to manage the information retrieval process due to the potentially large amounts of data presented on the map. In this paper, we present a spatial clustering approach to enhance the searching feature of MobiTOP, a geospatial annotation system. The technique, which is a modification of DBSCAN (Density based spatial clustering applications with noise) coupled with our ranking schemes, is compared against other techniques. The evaluation results suggest the viability of our approach, and implications are also discussed.

“…In the spirit of social computing, MobiTOP allows other users to annotate on the existing annotations. This collaborative annotating process forms a threaded discussion on a topic, allowing a community of users to exchange and explore information [7]. In previous work [12], [13], MobiTOP was evaluated with the primary goals of obtaining feedback about the application and investigating information behavior while using the system.…”

We investigate the usability of MobiTOP (Mobile Tagging of Objects and People), a mobile location-based annotation system. MobiTOP allows users to annotate real world locations with both multimedia and textual content and concurrently, share the annotations among its users. Equipped with a new interface as well as additional functionality such as clustering of annotations and advanced search and filtering options, a usability evaluation of MobiTOP was conducted in the context of a travel companion for tourists. The results suggested the potential of the system in terms of functionality for mobile content sharing. Participants agree that the features in MobiTOP are generally usable as a content sharing tool. Implications and future work are also reported in this paper.
