The User Interface Study Based on the Laterality Characteristics: the Universal Design and Its Effects for Different Handedness Persons

According to the principles of universal design, barrier-free, technology acceptance model, left-handed users are able to access information interface smoothly. However, nearly 45% of left handed users complained that there were some difficulties to use 3C. This kind of stimulus-response incompatibility should be remediated. However, the characteristics of interaction with interface are still not clear in users who are left-handed to further bother the formulation and decision of the intervention. Therefore, this 3-year project will study those characteristics first and then develop the web-based interface to find the best and universal interface for left- and right- handed users. In the first year, the effect of curser point orientation, menu position, scrolling position, mouse position on the performance of left- and right handed users will be studied. We will use the E’prime software and cursor moving and dragging software design the simulated interface to address the aforementioned issues. In the end of the 1st year, we will develop a web-based interface which will be used in the 2nd year. In the 2nd year, the best interface design for left- and right handed users will be formulated based on the data in the 1st year after testing and modifying the web-based interface developed in the end of the 1st year. Then, on the web-based interface platform, the users will conduct the task through using ideal interface for left-handed users, the task through using ideal interface for right-handed users, and the task through using current interface. The performance iof the 3 tasks will be compared to be sure what the best combination is for each group. Then, those data can be used to establish the universal design in the 3rd year. Moreover, in the end of the 2nd year, an universal web-based interface will be developed. In the 3rd year, the universal web-based interface will be tested and modified. Furthermore, the universal interface based on the combination of the aforementioned variables (cursor point orientation, menu position, scrolling position, mouse position) will be established. We expect the establishment of the combination won’t be worse than the ideal interface and will be better than the current interface for each group. After that, the users will conduct the task through using universal interface, through using their ideal interface, and through using the current interface. Then the effect of universal web-based interface can be identified. Finally, after the 3 years, the interaction characteristics with interface in left- and right handed users can be delineated. Moreover, the ideal web-based interface and universal interface can be developed.
