Abstract Title : Assessment of Visual Aiding in Virtual Reality-based Motor Task Performance Using a Haptic Interface
Abstract :
Within the recent past, virtual reality has become a popular tool for simulating motor task performance and facilitating skill training. Many research systems and programs have been developed incorporating 3-D displays and haptic devices. Considering the potential growth of application of these systems, the importance of familiarizing novice users with visual and haptic interfaces is critical. This study involved a group of students from North Carolina State University in a pilot experiment to test the hypothesis that visual cues, such as color changes in virtual objects in a VR simulation of a simple motor task, could reduce user cognitive processing load and accelerate learning of displays and control interfaces. The task was a virtual dice manipulation application requiring positioning and orientation of a die at a target location. Participants were divided into two groups at random, one performing the original version of the training task and the other performing the augmented version with visual cues available. The visual cues included two colors applied to the original color of the die: a red color highlighting the surface of the corresponding target face of the die, and a green colored surface when the die was oriented to the correct position by a participant. Performance data was automatically collected through the VR simulation and subjective ratings of system usability were gathered using the System Usability Scale. Results demonstrated that the augmented version of the simulation, including visual cues, helped participants to learn the VR system faster and to understand system functions better.
