Multiple linked-view exploration on large displays facilitated by a secondary handheld device
2019
Large displays are capable of visualising a large amount of data on multiple views including scatterplots and parallel coordinates and are often present in meeting rooms. They can be used to interact with a dataset and foster discussion among team members. Although some of these large screens have multi-touch capabilities, in many cases it is cumbersome to have to stand close to the display in order to interact with it. One of the solutions is to use a small handheld display to interact with the large display. This paper discusses how traditional interactions such as selection, brushing, and linking can be performed using a secondary handheld device. As a proof of concept, a system including scatterplots and parallel coordinates views is implemented. The interactions are straightforward and are useful for any interactive visual analysis application on a large display with wireless connectivity.
