M-Views Technology

Technology

Overview

M-Views technology allows for context-sensitive delivery of mobile cinema story elements, creation and submission of new mobile cinema story sequences, and computer-aided coordination of decentralized mobile cinema story production. Context-sensitive delivery is expected to minimize the interference between story presentation and participation by the audience. For example, the M-Views system can pay attention to the audience's daily schedule and present mobile cinema stories at its convenience. The ability to support creation and submission of new mobile cinema story sequences requires new authoring tools, content management, and participant administration. Computer-aided coordination tools can support people, who may or may not know each other, to collectively make mobile cinema stories. Collective production without a fixed central director (decentralized mobile cinema production) has its own advantages, compared with individual production or a centralized director. For instance, any member in a team can initiate a production; teamwork can reduce redundant work; and coordinated members can produce mobile cinema stories from different perspectives. The feasibility of decentralized mobile cinema is based on the decreasing cost of being both mobile and connected.

[Figure 1] Concept Architecture

The M-Views system design, as in Figure 1, primarily consists of two main modules: M-Views Production Platform (MPP) and M-Views Device (MD). An MPP also consists of a mobile cinema authoring tool, M-Studio, and an M-Views server. An MD consists of an M-Views Presenter (mobile cinema story presentation software on customized wireless PDAs) and an M-Views camera (Participatory Networked Camera).

To decrease the creation barrier, an authoring tool, M-Studio, has been created. The M-Studio authoring tool helps the mobile cinema story author to design, simulate, and adjust mobile narratives. M-Studio directly generates XML-based story script code that is required in order to present mobile cinema stories appropriately. To support participatory mobile cinema story experience, an M-Views Device (MD) is being developed. MD is designed to enable the story participant to view mobile cinema stories (M-Views Presenter) and to produce mobile cinema stories (M-Views camera). MD and M-Studio are connected through the M-Views server, which is responsible for detecting contextual information, delivering messages, parsing mobile cinema story scripts, handling video streaming, administrating data, and managing other mobile cinema story production and sharing tasks.
