Technical and vocational education emphasizes the development and training of hand motor skills. However, some problems exist in the current career and aptitude tests in that they do not truly measure the hand motor skills. This study used the Nintendo Wii Remote Controller as the testing device in developing a set of computerized testing tools to measure the hand motor skills. Through literature analyses, expert reviews, and analysis of the experimental data, it has been confirmed that these computerized testing tools are stable and effective; in addition, the test results were not influenced by gender or prior experiences with using sensor devices. Moreover, the computerized test was capable of diagnosing and measuring the hand motor skills of participants in a safe, low-cost, virtual testing environment. In focusing on the learning experiences from vocational school practice classes, this study provides a reference for decision-making regarding further education and career development.
