Factors Affecting Usability of Interactive 3D Holographic Projection System for Experiential Learning

Abstract

Innovative information display/control interface is an important issue for interactive experiential learning. In this study, an interactive 3D holographic projection system was developed. And it is used in a physiologically-based experiential learning. Learners can manipulate three-dimensional learning objects (targets) through the non-touch way of somatosensory and learn the characteristics of physiological structure in 3D holographic projection environment. The learners do not need any physical button interface. The embodied function of Gesture recognition is designed in this interactive system. Further, this study explored the system’s usability factors to improve the human-computer interaction and availability of this system. A total of sixty subjects (30 females and 30 males) participated in this usability experiment for the 3D interactive holographic projection learning system. These Subjects must complete an interactive experiential learning task about the physiological structure of the human organ. At the end of the task, the subject was asked to fill in the questionnaire of the five-point scale. Four important system usability factors are proposed through Principal Component Analysis (PCA). These factors include “Labeling”, “Continuity”, “Backlash”, and “Ambiences”. In addition, gender has no significant effect in each of these factors (p > 0.05).
