Usability Evaluation on XVC Framework for In-Vehicle User Interfaces

XVC (extensible viewer composition) is an in- vehicle user interface framework for telematics applications. It provides a document-oriented applications model enables drivers to make use of multiple information services simultaneously, while maintaining satisfactory control of their vehicles. XVC is a new client model which makes use of beneficial functions of in-vehicle navigation devices. However, there was no usability evaluation on XVC framework before this work. In this paper, we present the usability test on XVC framework that was performed to evaluate how the XVC client may affect the driving work of drivers while trying to make use of its functions. The evaluation was performed using the advanced automotive simulator system at KATECH (Korea Automobile Technology Institute). Furthermore, we also analyzed the advantages of XVC Framework and compared over non-XVC Framework through test results.
