The purpose of this investigation is to explore design features of virtual reality (VR) laboratories and assess their potential as a learning environment for engineering students. Virtual laboratories are a promising solution for meeting accreditation requirements for distance learning programs. They can also enrich the educational experience by providing immersive, interactive experiences for remote students while simultaneously training students to work in these environments. This current effort focuses on the development and application of virtual engineering laboratories using the Oculus Rift SDK2 headset combined with the Leap Motion Controller (gesture based, human-computer interface (HCI) device). A virtual environment was created to train users and assess the applicability of different components that can fulfill tasks requirements typically encountered in engineering laboratories, such as equipment control. We build upon a pilot study that investigated basic human-performance measures of buttons and add assessments of sliders and dials. The interface is provided by the LMC, so it is a gesture based interactive system. The investigation varied scale and spatial resolution of these components to provide insight into how effectively users can interface with them. A virtual sound radiation experiment was developed using this technology and assessed for its usefulness in meeting course learning objectives. The investigation has led to a better understanding of how combinations of scale and spatial arrangements effect the user's ability to successfully interact with the virtual components and their usefulness in meeting task requirements. The user's assessment of how visual and aural feedback can make-up for the lack of tactile feedback is also documented. Finally, student and instructor feedback of the virtual laboratory as an educational tool was highly favorable. This data will be used to guide the design and implementation of future VR based engineering laboratories.
