This paper proposes an input mapping system that can transform various input signals from next-generation virtual reality devices to suit existing virtual reality content. Existing interactions of virtual reality content are developed based on input values for standardized commercial haptic controllers. This prevents the challenge of new ideas in content. However, controllers that are not compatible with existing virtual reality content have to take significant risks until commercialization. The proposed system allows content developers to map streams of new input devices to standard input events for use in existing content. This allows the reuse of code from existing content, even with new devices, effectively reducing development tasks. Further, it is possible to define a new input method from the perspective of content instead of the sensing results of the input device, allowing for content-specific standardization in content-oriented industries such as games and virtual reality.

Robot Assisted Surgery

AbstractAccess to systems for robot-assisted surgery is limited due to high costs. To enable widespread use, numerous issues have to be addressed to improve and/or simplify their components. Current systems commonly use universal linkage-based input devices, and only a few applicationoriented and specialized designs are used. A versatile virtual reality controller is proposed as an alternative input device for the control of a seven degree of freedom articulated robotic arm. The real-time capabilities of the setup, replicating a system for robot-assisted teleoperated surgery, are investigated to assess suitability. Image-based assessment showed a considerable system latency of 81.7 ± 27.7 ms. However, due to its versatility, the virtual reality controller is a promising alternative to current input devices for research around medical telemanipulation systems.

Abstract LIRKIS CAVE is a unique immersive virtual reality installation with a compact cylinder-based construction and a high-quality stereoscopic video output rendered on twenty 55” Full HD LCD panels. While the video output of the CAVE provides a high level of immersion to a virtual world, its original implementation of peripherals support had a negative impact because of a limited number of supported devices and certain performance issues. In this paper we describe a new, distributed, peripheral devices support implementation for the LIRKIS CAVE, which solves the performance issues and allows for ease of integration of new input devices into the CAVE. We also present a successful integration of a special input device, the Myo armband,which allows a natural and unobtrusive gesture-based control of virtual environments. The integration includes a newly developed control and monitoring application for the Myo, called MLCCS, which utilization is not limited to CAVE systems or virtual reality applications.

This paper explores the human capacity to use visual feedback to compensate for directional mismatches between input devices and cursor motions in a standardized pointing task. Sixteen participants completed blocks of 64 trials as the directional mismatch between the input device and cursor motion was incremented clockwise by 7.5° over thirteen blocks, from 0° to 90°. At 90°, a vertical motion of the mouse mapped to a cursor motion directly to the right. Participants were robust to these acclimated directional mismatches up to 30°, at which point pointing performance began to decline. The findings have application in understanding the robustness of traditional input methods, as well as in virtual reality where visual feedback mismatches can be used for steering physical motions to make better use of constrained physical space or to reuse tactile stimuli.

This paper describes an experiment using Fitts' Law to evaluate performance in target acquisition tasks comparing a typical virtual reality (VR) display and input device with a typical computer workstation display and input device. The objective was to determine the effects of using VR hardware on target acquisition performance and validate Fitts' Law in a VR setting. Participants performed 2D target acquisition tasks varying width of target, distance of target, and angle of target from starting point. Factors that showed significantly different acquisition times included input device, distance from target, width of target, and angle of target from starting point. Display type did not show significance. In addition, acquisition times significantly increased throughout the experiment, indicating fatigue. Extending the use of Fitts' Law as an evaluation tool for VR systems is discussed.

This paper presents a novel virtual reality navigation (VRN) input device, called the VRNChair, offering an intuitive and natural way to interact with virtual reality (VR) environments. Traditionally, VR navigation tests are performed using stationary input devices such as keyboards or joysticks. However, in case of immersive VR environment experiments, such as our recent VRN assessment, the user may feel kinetosis (motion sickness) as a result of the disagreement between vestibular response and the optical flow. In addition, experience in using a joystick or any of the existing computer input devices may cause a bias in the accuracy of participant performance in VR environment experiments. Therefore, we have designed a VR navigational environment that is operated using a wheelchair (VRNChair). The VRNChair translates the movement of a manual wheelchair to feed any VR environment. We evaluated the VRNChair by testing on 34 young individuals in two groups performing the same navigational task with either the VRNChair or a joystick; also one older individual (55 years) performed the same experiment with both a joystick and the VRNChair. The results indicate that the VRNChair does not change the accuracy of the performance; thus removing the plausible bias of having experience using a joystick. More importantly, it significantly reduces the effect of kinetosis. While we developed VRNChair for our spatial cognition study, its application can be in many other studies involving neuroscience, neurorehabilitation, physiotherapy, and/or simply the gaming industry.

The emerging capabilities of smartphones are fuelling a rise in the use of mobile phones as input devices. The complexity of 3D object manipulation has become a challenge for traditional input. Sensors and interaction methods available in a modern smartphone may turn it into an interactive input device for manipulation of 3D objects. This study investigates the usability of a smartphone as an input device for 3D, and also explores its potential as an optimal input method for manipulating 3D space. As such, usability study requirements are formulated, and prototype 3D software with defined tasks developed, to aid in the usability studies. User satisfaction is investigated for each defined task, with the aim to explore optimal interaction methods for different approaches in manipulating 3D objects.

AbstractRecent advances in the field of web technologies, including the increasing support of virtual reality hardware, have allowed for shared virtual environments, reachable by just entering a URL in a browser. One contemporary solution that provides such a shared virtual reality is LIRKIS Global Collaborative Virtual Environments (LIRKIS G-CVE). It is a web-based software system, built on top of the A-Frame and Networked-Aframe frameworks. This paper describes LIRKIS G-CVE and introduces its two original components. The first one is the Smart-Client Interface, which turns smart devices, such as smartphones and tablets, into input devices. The advantage of this component over the standard way of user input is demonstrated by a series of experiments. The second component is the Enhanced Client Access layer, which provides access to positions and orientations of clients that share a virtual environment. The layer also stores a history of connected clients and provides limited control over the clients. The paper also outlines an ongoing experiment aimed at an evaluation of LIRKIS G-CVE in the area of virtual prototype testing.

Virtual reality (VR) is the term used to describe representation and perception in a computer-generated, virtual environment. The term was coined by author Damien Broderick in his 1982 novel “The Judas Mandala". The term "Mixed Reality" describes the mixing of virtual reality with pure reality. The term "hyper-reality" is also used. Immersion plays a major role here. Immersion describes the embedding of the user in the virtual world. A virtual world is considered plausible if the interaction is logical in itself. This interactivity creates the illusion that what seems to be happening is actually happening. A common problem with VR is "motion sickness." To create a sense of immersion, special output devices are needed to display virtual worlds. Here, "head-mounted displays", CAVE and shutter glasses are mainly used. Input devices are needed for interaction: 3D mouse, data glove, flystick as well as the omnidirectional treadmill, with which walking in virtual space is controlled by real walking movements, play a role here.
