Shared Interaction on a Wall-Sized Display in a Data Manipulation Task

Abstract

International audienceWall-sized displays support small groups of users working together on large amounts of data. Observational studies of such settings have shown that users adopt a range of collaboration styles, from loosely to closely coupled. Shared interaction techniques, in which multiple users perform a command collaboratively, have also been introduced to support co-located collaborative work. In this paper, we operational-ize five collaborative situations with increasing levels of coupling , and test the effects of providing shared interaction support for a data manipulation task in each situation. The results show the benefits of shared interaction for close collaboration: it encourages collaborative manipulation, it is more efficient and preferred by users, and it reduces physical navigation and fatigue. We also identify the time costs caused by disruption and communication in loose collaboration and analyze the trade-offs between parallelization and close collaboration. These findings inform the design of shared interaction techniques to support collaboration on wall-sized displays

Collaboration on large interactive displays: a systematic review

“…task and group characteristics, have received less attention. Four studies investigated various task characteristics (Jakobsen & Hornbaek, 2016;Tang et al, 2006;Schmitt, Buisine, Chaboissier, Aoussat, & Vernier, 2012;Liu, Chapuis, Beaudouin-Lafon, & Lecolinet, 2016) and group characteristics were examined as an independent variable in only one study (Martin-SanJose et al, 2015).…”

Visual Analytics on Large Displays: Exploring User Spatialization and How Size and Resolution Affect Task Performance

“…Other work has attempted to investigate large display system usage for data manipulation tasks [64], and the effects of display size and navigation technique on classification tasks [63]. However, these studies were performed in shared interaction settings.…”

Exploratory visualization of astronomical data on ultra-high-resolution wall displays

“…11-13 studying co-located users' collaboration strategies, 6,7 or users' perception of visual variables based on their relative position in front of the display; 14 designing interaction techniques that support physical navigation, by coupling ultra-walls with input devices such as touch frames, motion-tracking systems and wireless multitouch devices, in order to enable multi-device and multiuser interaction with the displayed data. Examples of such techniques include high-precision remote pointing techniques to enable users to interact when they are not within arm's reach of the display, 1 or mid-air panning and zooming techniques for navigating maps, images and datasets that exceed the display capacity of ultrawalls.…”

“…Wall displays also offer good support for collaborative work, enabling multiple users to simultaneously visualize and interact with the displayed data. [5][6][7] In this paper, we introduce FITS-OW, an application that enables astronomers to visualize and interact with very large FITS images and collections thereof. They can pan and zoom in images that are several hundred thousand pixels in both width and height, overlay the results of data analyses, fetch and display additional images of a specific object or region in the sky, showing observations in different ranges of the electromagnetic spectrum or made at different times.…”

“…6,7 Better support for collaborative work was actually identified by Wigdor et al 26 as something that would be highly valuable in some of the typical workflows of astronomers, including data analysis as well as the preparation of observation proposals. Their WeSpace platform, designed to facilitate face-to-face collaborative research sessions (which were not normally part of the astronomers' workflows), was informed by interviews and observations of astronomer group meetings, who expressed a "desire for synchronous co-located collaboration at various phases of their process".…”
