o:2270 Visualizing Spatial and Time-Oriented Data in a Second Screen Application en Mobile devices are more and more used in parallel, esp. in the field of TV viewing as second screen devices. Such scenarios aim to enhance the viewers' user experience while watching TV. We designed and implemented a second screen prototype intended to be used in parallel to watching a TV documentary. It allows to interactively explore a combination of spatial and time-oriented data to extend and enrich the TV content. We evaluated our prototype in a twofold approach, consisting of expert reviews and user evaluation. We identified different interaction habits in a second screen scenario and present its benefits in relation to documentaries. The collection bundles supplementary materials and research data for late breaking paper published at Mobile HCI 2017. information visualization; second screen; mobile; TV 2017-06-27T06:54:08.395Z 44 yes 46 Kerstin Blumenstein Christina Niederer person Markus Wagner person Wilhelm Pfersmann person Markus Seidl person Wolfgang Aigner person http://phaidra.fhstp.ac.at/o:2270 no yes 1 70 1552253 4
