Paper Abstract:
|
This paper presents a comparative two-group experimental study to explore if the addition of multimodal interaction
metaphors would enhance the usability of e-learning interfaces. Two independent groups of users were involved in the
experiment each of which tested one of the two interface versions provided by the experimental e-learning tool. The first
interface was based on textual approach in delivering learning information about class diagram notation. In the second
interface, recorded speech, earcons and avatar with simple facial expressions were combined to present the same
information. Efficiency, effectiveness, and user satisfaction were considered to evaluate the usability of both interfaces.
This paper reports and discusses results in regard to effectiveness only. Results of the experiment showed that users of the
multimodal-based interface significantly performed more successful tasks than their counterparts who used the text-based
interface. Therefore, adding audio visual interaction metaphors to the interface of e-learning applications can improve its
usability. |
