Forecasting tool on a mobile device

Within the domain of predictive analytics [7, 11], this paper presents a mobile application for data forecasting [9] and its corresponding user interface. Although forecasting tools already exist, none of them were available on mobile devices. With a focus on simplicity, we present the results of usability surveys, based on interactions assumptions we took. These interactions use current mobile best practices, mainly leveraging touch screens and multi-touch capacities. We also present performance results, and their impact and users perception. This paper illustrates this work through a use case on budget forecasting for a city mayor.
