When providing directions to a place, web and mobile mapping services are all able to suggest the shortest route. At times, however, when visiting a friend, we do not necessarily take the fastest route but might enjoy alternatives that, for example, offer beautiful urban sceneries. We have recently started to work on a framework that automatically generates routes that are not only short but also emotionally pleasant (e.g., that are happy). To quantify the extent to which urban scenes are pleasing, this framework uses a crowd-sourcing web platform that shows two street scenes of a city and let users vote on which one looks more beautiful, quiet, and happy. Such crowd-sourced ground truth allows us to build a graph of locations, weighted by the pleasantness scores, upon which pleasant routes can be extracted. We have initially applied this framework in the context of London and have obtained promising preliminary results.
