The Future of Visual Analytics? EU Flagship project – FuturICT

Kai Xu October 14, 2011 Research, Video, Visualisation 0

This is proposed to be a 10 year €1 billion (yes, not a typo) European project and was ranked number 1 after the first round. There is certainly lots of potential for Visual Analytics here.

INVISQUE requirements

Kai Xu November 5, 2010 Research, Software, Visualisation 0

Data type
- Structured text data (such as database records)?
- Semi-structured text data (such as emails)?
- Free text?
- Picture?
- Audio?
- Video?
- Anything else?
Data size

Displayed data item number (items on the screen)?
Processed data item number (for functions such as faceted search or dynamic querying; probably much larger than the displayed data item number)?

*These are for the data items in INVISQUE; they are different from how many records in the database.

Performance

Maximal response time for display, mouse/touch interaction, filter/query, …?

Interaction

Mouse: click/right click, drag, wheel (zoom), …?
Multi-touch gesture?: click, drag, 2/3/4 finger vertical/horizontal swipe, …?
Anything else?

Functionality

Reasoning space: what are the requirements?
Faceted search or dynamic querying?

Image quality (and how to measure it)?
2D?
3D?
Operating system independent?
Mobile platform?
Compatibility of any existing systems?
Development time frame?
