3D Visualization and Multimodal Interaction with Temporal Information Using Timelines

Abstract

Abstract. This paper reports on the design, development and evaluation of TimeViewer, a system allowing the storing, visualization and multimodal interaction with temporal and semantic information using timelines in 3D environments. We focus on the appliance of 3D interactive timelines for temporal information visualization, extending their capabilities with the novel concept of a time-tunnel. Our work is intended to investigate beyond the current state of the art interaction with 3D environments using a variety of input modes, such as touch and full-body kinesthetic interaction. Qualitative results were elicited through an evaluation with 16 users in order to assess the users' opinion of the system, the efficiency of the offered interactions and direct future research in the area.

Public Systems Supporting Noninstrumented Body-Based Interaction

“…In this case, players interact with the wall-projected game world through a virtual, two-dimensional, shadow of their body. Finally, the third case, TimeViewer (Drossis et al 2013), presents a public system for exploring timelines in both two and three dimensions that supports detailed body tracking in combination with single-hand, two-hands, and leg gestures. (Zabulis et al 2011) comprises seven interactive systems based on the research outcomes of ICS-FORTH's Ambient Intelligence Programme.…”

“…TimeViewer (Drossis et al 2013) is a system allowing the modeling, storing, visualization, and multimodal interaction with timelines (Fig. 8).…”

“…To assess TimeViewer in terms of usability and user experience but also to compare the various supported interaction methods, an evaluation study (Drossis et al 2013) was conducted with 16 participants (7 female and 9 male) the age of whom varied from 20 to 40 years old. Participants were instructed to express their thoughts aloud (Think Aloud) throughout the completion of each task.…”

“…3. skeleton tracking. The location and orientation of the user's individual body parts, as well as predefined gestures, are identified and mapped into a virtual world (e.g., Drossis et al 2013). …”

Estimating Visual Comfort in Stereoscopic Displays Using Electroencephalography: A Proof-of-Concept

“…Stereoscopic displays have been developed and used for years in computer science, for example to improve data visualization or to better manipulate virtual objects [5]. However, only recently did they begin to reach users beyond experts, at home, with "3D" movies or game consoles.…”
