“…Virtual reality (VR) headsets provide users with an immersive environment, and how to move in such an immersive environment has always been a problem worthy of study. With the development and commercialization of depth cameras, gesture-based VLTs such as using eye, 1 head, 2 hand, [3][4][5] or body movements 6,7 have become one of the research hotspots and have been implemented in many applications. [8][9][10] In gesture-based VLTs, the freehand-based VLT is a commonly used virtual locomotion interface, and there are several advantages when studying freehand-based VLTs.…”

Designing a natural, usable, and efficient gesture-based virtual locomotion interface in immersive environments has been challenging. Freehand-based virtual locomotion technique (VLT) has the advantage of eliminating the need to see the handhold devices and has been implemented in many applications.Translation control and direction control are two essential components of freehand-based VLT; however, the transfer function of turning speed in direction control has not been well explored. In this article, we systematically investigate the effects of turning speed on freehand-based virtual locomotion for the first time. A transfer function that maps the position of the hand to the turning speed is defined, and three parameters related to the turning speed are investigated. In the experiment, participants are asked to travel in the virtual environment from a first-person perspective with different parameters. Statistical analysis of the experimental results reveals the relationship between the turning speed and the traveling performance as well as the traveling experience.

“…However there has not been an equivalent improvement in the way in which users interact with the visualisations. Recognising that navigating a virtual world encompassing data at scales across many orders of magnitude requires a 7-dimensional representation of the view state, we have implemented our AeroSpace 7DoF interaction method [Stannus et al 2014] in a Geovisualisation testbed built around NASA's World Wind virtual globe software. Our approach expands the two-point touch method [Hancock et al ] to 3D with pinches replacing touches.…”

We introduce an intuitive gesture-based interaction technique for creating and manipulating simple three-dimensional (3D) shapes. Specifically, the developed interface utilizes low-cost depth camera to capture user's hand gesture as the input, maps different gestures to system commands and generates 3D models from midair 3D sketches (as opposed to traditional two-dimensional (2D) sketches). Our primary contribution is in the development of an intuitive gesture-based interface that enables novice users to rapidly construct conceptual 3D models. Our development extends current works by proposing both design and technical solutions to the challenges of the gestural modeling interface for conceptual 3D shapes. The preliminary user study results suggest that the developed framework is intuitive to use and able to create a variety of 3D conceptual models.
