User interface requirements. The user interface of the system should provide the end-users with the means to collaborate on, consume and reason about the raw and derived data streams as well as to manipulate and create new data stream computation instances. Using graphical and multi-modal query languages, the complexities of the underlying, textual query language are hidden from the end-users for a more intuitive access to the information contained within the data streams. Call for Action Express / Refine queries Set of queries for DSMS Suitable interaction conceptualizations are to be researched, taking into account the different use cases and scenarios in which the system is utilized, as well as the challenges arising from the volatile and real-time nature of the underlying data streams. The interaction conceptualizations are to be integrated into a collaboration tool, for multiple end-users with their roles to reason about the information and coordinate and agree upon and take actions. Furthermore part of the user interface will use appropriate modalities to notify end-users proactively about noteworthy occurrences regarding the system's state with respect to the users' observable activities. The collaborative visual environment should enable two different types of interactions, providing support to:
1. synchronous collaboration between co-located users 2. asynchronous distributed collaboration between remote users To support these tasks and enable collaboration among different workers, the user interface has to identify and provide accessible, flexible and editable artifacts for both individual-based and group- based exploration of data streams. This requires the definition of a group interaction space for collaborative data analysis, where users can interactively access data streams, as well as create, layout, arrange and share artifacts connected with data streams. Each artifact should be enriched with contextual information (such as labels, scales, legends, etc.) that allows users to correctly interpret the information being displayed. Users collaborating in a shared group interaction space should be able to jointly interact with a single shared view of data streams, or to create different views of the same data streams in a personalized workspace that can optionally be shared with other participants and mapped to or fuse with other views. By enabling the sharing and coordination of multiple views of data streams in a common workspace, the visual environment allows users with d...
User interface requirements. 6.1 Users shall be able to view the position of their fleet vehicles at any point of time via a standard web browser (eg. Microsoft Internet explorer, version 8.0 (or later)) on their personal computer. The primary display shall be a map view of state wide fleet vehicles as well in individual regions via login passwords
6.2 The system shall allow viewing of a vehicle in motion leaving tracks or "breadcrumbs" as it travels showing all operations (GPS & Telematic data) as they occur. Users shall be able to view the above mentioned data for their entire fleet or select a specific vehicle(s) for a login session using a Filter Tool. Unit Max Max 6.3 The map display shall be such that vehicle position and status automatically updates on screen without any input from the end-user. Additionally, end-users shall be able to view the status of monitored on-board vehicle equipment with each fix or report.
6.4 The system must have an easy "intuitive" navigation sequence (i.e. navigator bar and/or tabs for easy access to various functional screens). Tools shall include but not be limited to: Map navigational tools (zoom in/out, center, pan, etc.); Automatic Vehicle Location Tool; Breadcrumbs; Filter Tool; Historical Data; and Reports.
6.5 User shall have options to select from different map views of the map in order to accommodate varying business requirements, desktop equipment performance, and Internet connectivity.
