SMART DATA SELECTOR

Reminder

Problem Domain

Dataflow in SolutionExperimental Aircraft

Experimental aircraft transmits data to ground receivers

Ground ReceiversSeveral ground receivers record the data

Preprocess unit (XXX-Telemetry records creator)

The raw data that was recorded in each receiver is formatted and metadata files are created

Smart Data Selector (SDS)

Integrates all inputs to one master record that is as close as possible to the original data

Analysis tools and QuickView Master record is used for analysis of flight and plotting

Use Cases

Use CasesUse Case 2 [UC2]: generate masterPrimary Actor: Telemetry technician (or common user).Interests: The technician wants to generate a master output from source inputs.Pre-conditions: User opened a new job, loaded sources and defined a configuration.Post-conditions: The master is generated and saved in the job directory with metadata information.Main success scenario: 1. User clicks on "play" icon. 2. An estimate for the execution time is displayed for the user and he is asked to confirm. 3. After confirmation, master output and metadata information are generated according to user configuration and saved in job directory.Main fail scenario: 1. User clicks on "play" icon. 2. An estimate for the execution time is displayed for the user and he is asked to confirm. 3. User cancels master generation.

User Interface

The interface will be implemented according to the KISS (Keep It Simple and Stupid) principles. The interface is designed according to the guidelines and the physical, technological, cognitive limitations, learning and attention limitation that Lansdale & Ormerod (1994) presented.
