Virtual Reality (VR) can be used as an assistive system to learn with immersive visualization and interactive control. Anatomy is a branch of biology that is difficult to learn using textbooks because of its limitations in displaying anatomical objects in two-dimensional media. VR can display anatomical objects in the form of a three-dimensional virtual world. Besides being assisted by its immersive appearance, the interactivity learning system can also be improved by using the appropriate VR control device. In this study, three controls were used with different features and functions, namely VIVE Controller, Leap Motion Controller, and Senso Glove, and a user experience study was conducted. The user was asked to use the anatomy learning system with three different control devices, and then the user was asked to fill out a survey form, which uses the Liker scale. The survey focuses on the level of acceptability and user satisfaction in the usability factor, ease of learning, the suitability of movement, suitability of display, and haptic feedback provided by each VR controllers. From this study, it was found that the VIVE Controller is superior compared to the Leap Motion Controller and Senso Glove in terms of usability, ease of learning, movement suitability, and display suitability. The senso glove is superior in terms of haptic feedback satisfaction.
The availability of control devices that use hand and finger movements in virtual reality systems has an essential role in increasing the level of interaction in the virtual reality system. Hand and finger movements in a virtual reality system can be displayed either in the form of a controller that resembles its original shape or in the form of a virtual hand. The translation motion and rotation of the virtual reality controller can be used as input to the system. In addition, the virtual reality controllers allow the use of buttons or gestures as triggers on the system. Input in the form of translational and rotational movements on the virtual reality controller and its triggers can be applied to anatomical learning systems in a virtual reality environment. Virtual reality controller has a role as a system control tools. Different virtual reality controllers have different levels of feasibility to the system, similarity when used, and ease of learning. Therefore a comparison was performed on three virtual reality controllers that have different usage methods and features. The three tools chosen in this study are the VIVE Controller, Leap Motion Controller, and Senso Glove. These three tools have different ways of using and feature, including differences in touching the user or not, triggers in the form of buttons or gestures, and whether or not haptic feedback is available. The analysis of the use and its comparison between these three virtual reality controllers are the outcome of this study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
