“…Laha and Bowman [21] proposed the volume cracker, a technique that uses a Leap Motion (a commercial visionbased hand-tracker) and allows-via mid-air interaction-the direct manipulation and separation of volumes in scientific visualisations. Miranda et al [27] studied the use of gestures to support 3D scatterplot InfoVis tasks. They found three main categories of issues using mid-air gestures: the size of the tracking volume; ambiguity of the gestures; and ambiguities in depth perception while using a 2D screen.…”

We introduce the concept of "spatio-data coordination" (SD coordination) which defines the mapping of user actions in physical space into the space of data in a visualisation. SD coordination is intended to lower the user's cognitive load when exploring complex multidimensional data such as biomedical data, multiple data attributes vs time in a space-time-cube visualisation, or three-dimensional projections of three-or-higher-dimensional data sets. To inform the design of interaction devices to allow for SD coordination, we define a design space and demonstrate it with sketches and early prototypes of three exemplar devices for SD coordinated interaction.

“…Studies have also shown positive results while teaching and training the VR interaction gestures to people with a disability such as Down Syndrome [42]. The LMC also has been used by Miranda et al [43] to categorize the issues with mid-air InfoVis (Information Visualization) interaction. However, the issue we have noticed and explained later in this paper is not mentioned in their work due to the different use of the LMC.…”

The Effect of Semi-Transparent and Interpenetrable Hands on Object Manipulation in Virtual Reality

Manipulating objects with the hand is a common task in Virtual Reality (VR). However, some issues can occur during these manipulations. Occlusion is one issue that happens when the virtual hand covers an object, and therefore the perception of that object is hindered. Semi-transparent hands could solve this problem. Another issue is the difficulty of delicate hand object manipulation. By using interpenetrable hands, turning off the physics of the hands, this difficulty might decrease. Still, there is a lack of research into how significant the impact is while using these methods. In this paper, with the designs of semi-transparent hands and interpenetrable hands, we present the results of our conducted user study focusing on the effect of semi-transparent and interpenetrable hands on hand object manipulation tasks in virtual reality. The user study includes a VR environment where participants are asked to perform tasks. These tasks are recorded in objective results of accuracy and speed. Afterwards, they fill out a questionnaire about their opinion on the difficulty while using the different methods in which the subjective findings are recorded. Additionally, we improved the semi-transparent hands by adding a feature that smoothly transitions the hand from opaque to semi-transparent. As an input device, we used the Leap Motion Controller (LMC) for this user study. However, any hand tracking sensor that tracks hands from the VR headset's point of view could be used. Semi-transparent and interpenetrable hands have shown significant improvement for precise manipulation, which was verified by user feedback from the questionnaire and the data from the tasks.

“…However, data exploration involves many tasks, such as filter, select, adjust or annotate the dataset, which are not entirely covered in existing solutions. Indeed, a large interaction vocabulary is required and approaches based on mouse, touch and mid-air interaction fail to offer enough degrees of freedom (DoF) [17,34,39]; other solutions are often ambiguous and tiring (especially mid-air gestures [7,34,35]); finally many restrict the user's interaction to a defined place, usually a desktop, to use the input device (3D mouse or other [30]). The challenge then is to provide an interactive solution for immersive environments that preserves the freedom of movement of mid-air interaction and the DoFs of tangible interaction.…”

Recent technological advances in immersive devices open up many opportunities for users to visualize data in their environments. However, current interactive solutions fail at providing a convenient approach to manipulate such complex immersive visualizations. In this article, we present a new approach to interact in these environments, that we call On-Body Tangible interaction (OBT): using the body to physically support the manipulation of an input device. The use of the body to support the interaction allows the user to move in his environment and avoid the inherent fatigue of mid-air interactions. In this paper, we explore the use of a rolling device, which fits well on-body interaction thanks to its form factor and offers enough degrees of freedom (DoF) for data manipulation. We first propose a new design space for OBT interactions, and specifically on the forearm. Then we validate the feasibility of such an approach through an experiment aimed at establishing the range, stability and comfort of gestures performed with the device on the forearm. Our results reveal that on-body tangible interaction on the forearm is stable and offers multiple DoFs with little fatigue. We illustrate the benefits of our approach through sample applications where OBT interactions are used to select and execute space-time cube operations.
