Interactive Input and Visualization for Planning with Temporal Uncertainty

Data with temporal uncertainty is ubiquitous in everyone's life. Popular examples are holiday planning or train trips. There are several approaches to visualize temporal uncertainty, but common research usually does not take uncertainty into account, neither as input nor output. We propose a new approach that provides both an interactive drawing for data with temporal uncertainty and their respective visualizations. The user can draw both variable and fixed activities and also has the possibility to set probability distributions and enter indefinite activities. A quantitative user study shows the need and suitability of our new approach.
