Item Designing a scanning on-screen keyboard for people with severe motor disabilities(Springer Berlin Heidelberg, 2008-01-01) Lin, Y. L.; Wu, T. F.; Chen, M. C.; Yeh, Y. M.; Wang, H. P.This study aims to explore the effectiveness of a scanning on-screen keyboard for persons with severe motor disabilities. In order to enhance the typing performance, the on-screen keyboard employs the group-row-column scanning and a frequency-of-use layout. Besides the international alphabetical layout, the on-screen keyboard also provides two Chinese selection layouts for Chinese users. The usability evaluation was carried out with simulations and experiments. The usability evaluation was conducted to compare the performance with that of the QWERTY layout of block scanning built in Microsoft Windows XP. The results demonstrated that the performance of using the scanning on-screen keyboard was better than that of using the Windows XP. No significant difference between the error rates of the two different keyboards was found.Item Designing a scanning on-screen keyboard for people with severe motor disabilities(Springer Berlin Heidelberg, 2008-01-01) Lin, Y.

L.; Chen, M. C.; Wu, Y. P.; Yeh, Y. M.; Wang, H. P.This study was to design an alternative on-screen keyboard and evaluate the efficacy of this innovative layout design for people with severe physical disability. The matrix keyboard layouts was designed based on human computer interaction. A repeated experiment was performed to compare the speed and accuracy of text entry with point-and-click input method between the matrix on-screen keyboard and the Windows XP QWERTY virtual keyboard. Data analysis revealed that the matrix on-screen keyboard provided better performance for the participant. The result also indicates that layout adaptation assessment is a valid tool to confirm proper layout size for users and that alphabetic order is better than QWERTY order for a novice user to learn a new on-screen keyboard. A usability study was undertaken to evaluation the performance of the double click instead of the point-and-click plus Shift key input method. The possible causes of the results and suggestions for further studies are discussed.
