The objective of the project is to successfully provide clear visual information of so-called “sensitive” data. Indeed, the data concern the subject of network security and require vigilance in their communication. The data are displayed on a giant screen in the reception hall of the Saint-Denis site, an area where visitors wait for their appointments. The visualization must then make it easier for visitors to wait by guaranteeing them a pleasant data reading experience in a short period of time. In order to be able to process all the available information, 10h11 has developed a scenario of the data in the form of interchangeable “tiles”. Why did we consider this system of representation?
One category, several data
The dataset is characterized by several categories and several degrees of information in each category. The difficulty of the job is to store all the information without degrading the reading experience for the user. Our scenario proposes to create several degrees of information to the user through an animation. The main data is then cut and redefined by secondary data to create a “tile” of the subject by category. This animation provides a quick overview of the main data, then, via a “zoom” of the tile, provides more detailed, compared and contextualized data in a rotation of the information. The system is fun and gives us a freedom of action with the most important data.
A rotation system, a controlled waiting time
To arouse the user’s interest, the time before rotation of each tile must not exceed 1 minute. Thus, the user is caught in the game of waiting in front of the screen to discover all the information in a few minutes. The objective of “helping people to wait” for data visualization thus plays its full role. The data that is not in the so-called “ZOOM” area is only slightly detailed, but still gives access to a quick reading of the information. It is this limited access that creates frustration, a desire to discover more information, that leads the user to consult this dashboard. The full rotation time of the 5 tiles thus lasts 5 minutes, a significant gain in the quality of SNCF’s reception and information on its Saint-Denis site.
1 tile, 1 main shape
To make it easier to read, each subcategory has a predominant form in its representation of the data. Naturally, the viewer understands the categorization by the visual forms used for each tile. We used the following forms for their interpretation performance in relation to the type of data concerned by each tile:
- Safety training : hollow diagram, contour circle
- Personal injuries : accumulation graph, rounded-angle rectangle
- Collisions : pyramid diagram, triangle
- Lost time : diagram comparisons of solid bubbles and variable scales of the solid circle
- ESR : gauges and bubble diagrams
