Item A process of selecting computer access devices for persons with physical disabilities.(2010/07/24-29) Wu, T. F.; Chen, M. C.; Meng, L. F.Item The performance of mouse proficiency for adolescents with intellectual disabilities.(Springer Berlin Heidelberg, 2010-07-01) Wu, T. F.; Chen, M. C.; Wu, C. F.Information and computer technology has grown rapidly and played an essential role in our education, vocation, and daily life. However, for students with intellectual disabilities, effective cursor control is challenged. The purpose of this study is to investigate the performance of mouse control of 10 adolescents with intellectual disabilities compared with their aged peer. A mouse proficiency assessment software was utilized to collect the data. The results indicated that the adolescents with intellectual disabilities who had mouse using experience do not perform as efficient as their peers without disabilities, although they could use the mouse with high accuracy rates. The adolescents with intellectual disabilities spend less reaction time, longer total time and movement time, larger ratio of PL/TA, more movement units to complete pointing and clicking tasks. The results provide essential reference for designers of computer assisted learning software when developing e-learning material for adolescents with intellectual disabilities.Item Characteristics and solutions of digital divide for People with physical impairments in Taiwan(Springer Berlin Heidelberg, 2008-01-01) Yeh, Y. M.; Wu, T. F.; Meng, L. F.; Chen, M. C.; Wang, H. P; Wu, J. G.; Chu, C. N.; Lin, Y. L.; Yeh, C. C.The purpose of this study is to narrow down the digital gap between people with and those without physical impairments in Taiwan. To better understand the need of the digital learning for people with physical impairments, the authors have created the digital characteristic assessment scale, digital need assessment scale, and developed the mouse training system and on-screen keyboard assessment system. In order to comprehend the performance and practicability of the scales and systems, this integrated project have also applied these tools to evaluate and train the clients with muscular dystrophy and cerebral palsy.Item The effectiveness of a pedagogical agent-based learning system for teaching word recognition to children with moderate mental retardation(British Educational Research Association, 2008-01-01) Lin, Y. L.; Chen, M. C.; Wu, T. F.; Yeh, Y. M.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 The Performance of Mouse Proficiency for Adolescents with Intellectual Disabilities(Springer Berlin Heidelberg, 2010-01-01) Wu, T.

F.; Chen, M. C.; Chu, C. N.; Yeh, C. C.; Wu, T. F.To know the directional efficiency of cursor moving is important for the purpose of guiding the rearrangement of icons and toolbars in the window environment. This rearrangement resolution can achieve better computer access especially in the clients with quadriplegia. However, the information about the directional efficiency of cursor movement is not clear even in the typical persons. Therefore, before surveying the quadriplegics, typical persons were researched in this study. Four typical persons simulated quadriplegics to operate trackball with their right dorsal hand and the kinematic parameters of cursor moving were measured. The single subject experimental research (SSER) with alternating treatments design was used to compare the effects of four cursor moving direction (right to left, down to up, left to right, and up to down) on the kinematic variables. The prior auto-correlation coefficients and Bartlett’s ratio values were computed to make sure there was no any series dependence between measuring points before conducting parametric one-way repeated measures ANOVAs. From analyzing the parameter of deviation from the straight line, velocity, movement unit and execution time, the efficiency to move on the horizontal direction (left to right or right to left) was better than move on the vertical direction (up to down or down to up). To further know the cursor kinematic performances in patients with quadriplegics will be important.Item The effect of different representations on reading digital text for students with cognitive disabilities(British Educational Research Association, 2009-01-01) Chen, M. C.; Wu, T. F.; Lin, Y. L.; Tasi, Y. H.; Chen, H. C.Item CAT motor: An innovative system to detect the behavior of human computer interaction for people with upper limb impairment(Springer Berlin Heidelberg, 2007-01-01) Cko, C. C.; Chen, M. C.; Wu, T. F.; Chen, S. Y.; Yeh, C. C.This paper described a system which could measure cursor movement and control site motion simultaneously. In addition to evaluate a client’s pointing and selecting proficiency, CAT Motor system, developed on the basis of the previous CAT system, was also used to detect the motion of his control site. This feature could provide clinical professionals more detailed information when comparing the difference of performance among devices. The CAT Motor system consisted of four basic types of mouse operating skills, including clicking, cursor moving, cursor moving and clicking, and dragging. The CAT Motor recorded the location and the response of the pointing device and captured the picture of the control site synchronally. Then, the system visualized the results of cursor moving and control site motion on the screen. The CAT Motor system not only provided the professionals with an objective mean of evaluating specific difficulties of mouse operating difficulties, but also allowed them to evaluate the effort of the motor control training. Besides, this paper had some suggestions for the research in the future.Item Performance of different pointing devices on children with cerebral palsy(Springer Berlin Heidelberg, 2007-01-01) Wu, T. F.; Chen, M. C.With the popularization of graphical user interfaces (GUIs), pointing devices have become standard equipment of most computer systems. However, for people with motor impairments, accurate cursor control is often difficult or impossible to achieve. The focus of this study is to empirically compare effectiveness of three different pointing devices on children with cerebral palsy in order to select the most efficient device for each individual. Computerized Assessment Tool was developed to assess clients’ cursor control performance and to provide proper recommendations of pointing devices based on the results of assessments. Performance of pointing, clicking, and dragging of using different devices was measured. The results of this study indicated that Joystick seems to be the most effective device for children with cerebral palsy to perform cursor control tasks. However, factors such as each participant’s experience and preference may be related. The instrument use in this study, CAT, seems to be a convenient tool for rehabilitation therapists to assess clients’ cursor control performance. Replication of this study using a larger sample size, or recruiting clients with different diagnosis and various ages should be developed.
