Abstract
Advances in mobile technology have enabled virtual reality (VR) and augmented reality (AR) systems to become more accessible and affordable. There are several devices that can be integrated with the mobile platform to make the applications more interactive, such as Leap Motion (LM). In this article, an AR environment has been designed that uses an Android smartphone with the LM. It has been evaluated for usability and accuracy by designing 15 sphere-targeting tasks that require the participants to use the LM to place the tip of a virtual index finger within the sphere. The task completion time and fingertip location were recorded, and the accuracy of the task was evaluated by calculating the distance between the fingertip location and the center of the sphere in three dimensions and each individual direction. Participants were the most accurate in the width and height directions, but there was a significant decrease in accuracy in the depth direction. Several participants experienced a decrease in task completion time as they progressed through the tasks, but half of the participants experienced tracking problems that increased their task completion times. Overall, the participants reported that the system was very intuitive and performed as designed; however, further improvements are needed.
