Analysis of interaction user interface patterns and usability study in computer assisted instruction for Tablet PC

Tablet PCs are used in many colleges and universities for improving the student learning, and enhancing the delivery of course materials. This paper presented the suitable UI patterns design for CAI of the Chemistry course on the Tablet PC. In the prototype, we developed the UI patterns for the CAI based on UI design principles, ISD model and usability evaluation, which are important for a CAI application on the Tablet PC. Since the Chemistry content is difficult to understand, we applied the interaction pattern in the design of CAI to support the course in order to give the effective learning and motivating the students. The result shown that the students were pleasant and satisfy the interface of the CAI application. The suitable interactive UI patterns of CAI on the Tablet PC help them to improve the effective of learning.
